Insecticides. [1] One which shows promise as a biocontrol agent is Aphelinus asychis. Ranjitha, G., M.R Srinivasan, and R Jegadeeswaran. Unlike many aphid species, melon aphid is not adversely affected by hot weather. [3], Predators include midges, lacewings, syrphid fly larvae, anthocorid bugs and ladybirds (ladybeetles). The wide host range of melon aphid makes crop rotation a difficult tactic to implement successfully. This aphid is globally distributed, located in all but the coldest terrestrial habitats. (Hemipt. Credits: Paul M. Choate, UF/IFAS Figure 5. 45 (5), 416. The body appears dull because it is dusted with wax secretions. Honey dew secreted by the aphids fall on the betelvine leaves and lead to the development of sooty mould which appear as black spots. Aphids (Homoptera:Aphididae) colonizing cotton in the United States. Studies on the quantity dynamic of pear aphids and their natural enemy in Kunming region. Melon aphids, Aphis gossypii Glover, on okra. disease transmission, but this is expensive to implement on a large scale. [1] In the former Soviet Union it is found up to 54°N. More than 48 species (belonging to 19 families in 9 orders) of natural enemies of this aphid have been found in cotton fields in China. Time of planting may influence potential aphid population increase potential. Indian Journal of Entomology 2(1):14 >> Aphis gossypii; Knowlton. [1] In Russia various wild plants are hosts to the overwintering eggs. Wingless females of Aphis gossypii are usually medium-sized and blackish green or dark green mottled with lighter green (see first two pictures below). There are many aphids attacking a wide range of crops; Aphis gossypii, described here, is common in Pacific island countries. [3], The wingless female cotton aphid has an ovoid body about two millimetres long in varying shades of green. In Aphis gossypii (bottom) the cauda is pale to dusky and has two or three pairs of setae, in Aphis spiraecola (top) the cauda is dark brown to black and has five or six pairs of setae. Goff CC, Tissot AN. Webb SE, Linda SB. Egg: When first deposited, the eggs are yellow, but they soon become shiny black in color. In the south, cotton is an important host, which explains the second common name, cotton aphid. effect on virus transmission by non-colonizing, transient aphids, though insecticides can prevent produced and overwintering hosts are more numerous, including dock, Rumex crispus; Lamium Pronunciation of Aphis gossypii with 1 audio pronunciation and more for Aphis gossypii. Ants are commonly found associated with melon aphid but they are there to collect honeydew, and may even hinder predation by other insects. Florida Citrus Management Guide for aphids. A. gossypii is small, adaptable, easily spread, with a rapid reproductive rate, and the ability to cause serious plant injury in isolated communities. Earias spp. [5], Resistance to carbamates and organophosphates has been traced to two variant acetylcholinesterase genes in A. gossypii, MACEA and MACEB. Aphids are easily dislodged from plants if they are sprayed forcefully with water, reducing their abundance and lessening plant damage. Other vegetable crops sometimes affected are asparagus, bean, beet, carrot, celery, parsley, parsnip, pea, pepper, radish, tomato, eggplant, and okra. In hot conditions or when crowded they are smaller, and these dwarf forms are a very pale whitish yellow (see third picture below). Figure 1. Aphids: (Toxoptera aurantii and Aphis gossypii) They colonize on the underside of tender leaves, succulent stem, flower buds and small cherelles. [3] Winged forms then migrate to secondary host species in the families Rosaceae, Chenopodiaceae, Malvaceae, Cruciferae, Cucurbitaceae, Solanaceae, Compositae and others. Handbook of Vegetable Pests. The cylindrical black siphunculi are wide at the base and one fifth of the body length. “Hyperspectral Radiometry for Detection and Estimation of Damage Caused by Aphids Aphis Gossypii(Glover) in Cotton.” In A Book of Extended Summary of National Sympisum on Emerging Trends in Ecofriendly Insect Pest Management Eds. Ma L(1), Li MY(1), Chang CY(1), Chen FF(1), Hu Y(1), Liu XD(1). Because melon aphid sometimes overwinters in greenhouses, and may be introduced into the field with transplants in the spring, it has potential to be damaging almost anywhere. Small yellow forms apparently are produced in response to crowding or plant stress. In addition, they secrete a great deal of honeydew which provides a substrate for growth of sooty mold, so the quality of fruit may be impaired and the photosynthetic capacity of foliage further hindered. Stoetzel et al. There is often a great deal of leaf curling and distortion which hinders efficient photosynthesis. Photograph by Paul M. Choate, University of Florida. This sap-sucking insect affects plants via direct feeding and indirectly via plant viral disease transmission (more than 50 plant pathogenic viruses known). The cotton aphid, Aphis gossypii, has a worldwide distribution and causes damage to numerous economically important crops 17. Row covers can be used to inhibit development of aphid populations. Use of insecticides for other, more damaging insects sometimes leads to outbreaks of melon aphid. Management Raise papaya seedlings under insect-proof conditions. Aphid : Aphis gossypii (Aphididae: Hemiptera) Damage symptoms: Both nymph and adults desap the tender shoot and leaves causing yellowing, curling and crinkling in leaves of support plants viz.,Sesbania spp. Adult: The wingless (apterous) parthenogenetic females are 1 to 2 mm in length. Photograph by Paul M. Choate, University of Florida. Melon aphids will transmit viruses to crops that they do not colonize. Melon aphids, Aphis gossypii Glover, tended by ants. Figure 6. Cotton aphid: Aphis gossypii Symptom of damage. Release of the parasitoid Aphidius colemani (Hymenoptera: Braconidae) into greenhouses can effectively reduce populations of melon aphid feeding on chrysanthemum, and this would likely work equally effectively for some vegetable crops. The cotton aphid. Proceedings of the Utah Academy of Sciences, Arts and Letters 18:67 >> Aphis gossypii; Shinji. Phytopathology 76: 1276-1281. The egg-laying (oviparous) female is dark purplish green; the male is similar. Aphids, particularly Aphis gossypii and others (Hemiptera: Aphididae) are soft-bodied insects, 1–2 mm long, yellowish green to black, with or without wings. Here, both males and sexual females are produced, mating takes place and the females lay eggs which overwinter, ready to repeat the life cycle the following year. In India Papaya ringspot virus (PRSV) is transmitted by both A. gossypii and M. persicae (Kalleshwaraswamy et al. They often have a dark head, thorax and wing pads and the distal portion of the abdomen is usually dark green. quite variable in color: light green mottled with dark green is most common, but also occurring are whitish, yellow, pale green, and dark green forms. At least 60 host plants are known in Florida, and perhaps 700 host plants worldwide. Viviparous (gives birth to live young) females produce a total of about 70 to 80 offspring at a rate of 4.3 per day. The optimal temperature for reproduction is reported to be about 21 to 27 degrees. Females continue to produce offspring without mating so long as weather allows feeding and growth. Nymphs (mixed ages) and dark form of wingless adult of melon aphids, Aphis gossypii Glover. Aphis gossypii is one of the most biologically diverse and widely distributed aphid species. The cornicles also are black. Tamil Nadu Agricultural University (TNAU), Madurai 625104 **Department of Agricultural Entomology, TNAU, Coimbatore 641003 *** ... Aphis gossypii. Honeydew is excreted by the aphids and this allows sooty moulds to grow, resulting in a decrease in the quantity and quality of the produce. Glover (Hemiptera: Aphididae), is a cosmopolitan, polyphagous insect and attacks numerous crops including cotton, vegetables, Southwestern Entomologist 14: 302-313. Inst. Figure 6. Several members of the Aphidiinae and Aphelinidae wasp families are parasitoids of aphids. Arkansas Agricultural Experiment Station Bulletin 462. 1992. Melon aphid occurs in tropical and temperate regions throughout the world except northernmost areas. The oval eggs are yellow when first laid but soon turn glossy black. Marco S. 1986. Inadvertent destruction of beneficial insects is purported to explain this phenomenon However, resistance by melon aphid to chlorinated hydrocarbon, organophosphate, and pyrethroid insecticides is widespread. Melon aphids, Aphis gossypii Glover, on okra. The duration of the adult's reproductive period is about 15 days, and the post-reproductive period five days. The aphids are a vector of crinkle, mosaic, rosette, CTV and other virus diseases. It has a very wide host range with at least 700 host plants being known world-wide. In the United States, it is regularly a pest in the southeast and southwest, but is occasionally damaging everywhere. Evaluation of spunbounded polyethylene row covers as a method of excluding insects and viruses affecting fall-grown squash in Florida. 1932. 1996. Many of the natural enemies known to be effective against other aphids also attack melon aphid: ladybird beetles (Coleoptera: Coccinellidae), flower flies (Diptera: Syrpidae), and braconid wasps (Hymenoptera: Braconidae). One other species commonly encountered is Aphis spiraecola Patch, the spirea aphid. It is common in North and South America, Central Asia, Africa, Australia,[3] Brazil, East Indies, Mexico and Hawaii and in most of Europe. Figure 2. For many organisms which cannot internally regulate their own temperature, development is dependent on temperatures to which they are exposed in the environment. The head and thorax are black, and the abdomen yellowish green except for the tip of the abdomen, which is darker. Reflective mulches also affect aphid populations under open-field conditions. The winged female has a fusiform body. noted previously, the eggs normally are deposited on catalpa and rose of sharon. It is a true bug and sucks sap from plants. Infested crops should be destroyed immediately after harvest to prevent excessive dispersal, and it may be possible to destroy overwintering hosts if they are weeds. It thrives outdoors in southern Europe but survives only under glass in northern Europe. Some other important crops injured regularly are citrus, cotton, and hibiscus. melon aphid from most other common vegetable-infesting aphids. Their feeding also causes a great deal of distortion and leaf curling, hindering photosynthetic capacity of the plant. [4], The adults and nymphs of the cotton aphid feed on the underside of leaves or on the growing tips of shoots, sucking juices from the plant. Excessive and unnecessary use of insecticides should be avoided. The legs are yellow, as are the antennae which are three quarters of the length of the body. Arq. Aphididae) (Cotton Aphis, Melon Aphis). Both aluminum and plastic mulch are reported to be useful for suppression of watermelon mosaic virus. The host range of Aphis gossypii is dependent on aphid genetic background and feeding experience. The cotton aphid, Aphis gossypii Glover, is a major pest of cotton in China. Alon Hanotea. Females continue to produce offspring without mating so long as the weather is favourable for feeding and growth. Academic Press, San Diego. [1], It is not known where this species originated, but it is now found in tropical and temperate regions throughout the world except extreme northern areas. plants.

Browse the list of datasets and find organisations you can join if you are interested in participating in a survey for species like Aphis (Aphis) gossypii Glover, 1877 Photograph by P.M. Choate, University of Florida. The dispersants typically select new growth to feed upon, and may produce both winged (alate) and wingless (apterous) female offspring. Melon aphid has a very wide host range. Scientific name: Aphis gossypii. The melon aphid. Nymph: The nymphs vary in color from tan to gray or green, and often are marked with dark head, thorax and wing pads, and with the distal portion of the abdomen dark green. Also, the incidence of virus diseases transmitted by aphids is lower, and crop yields are higher, where reflective mulch is used. A. gossypii Cotton Coimbatore (TNAU) JQ690330 JQ690300 JQ690322 A. gossypii Cotton Akola, Maharashtra JQ690331 JQ690301 JQ690323 A. gossypii Sponge guard Jaipur, Rajasthan JQ690332 JQ690302 JQ690324 A. gossypii Brinjal Jaipur, Rajasthan JQ690333 JQ690303 JQ690325 A. gossypii Pumpkin Jaipur, Rajasthan JQ690334 JQ690304 JQ690326 Photograph by Lyle J. Buss, University of Florida. The legs are pale with the tips of the tibiae and tarsi black. Parthenogenesis on these hosts allows large populations of aphids to build up quickly. Under warm conditions, a generation can be completed Elimination of alternate hosts of both aphids and the virus diseases is often key to disease management; both weeds and crop plants can harbor the disease and vectors. Row covers, A review of known and potential factors affecting the population dynamics of the cotton aphid. Plant disease free seedlings.

[2], The cotton aphid has a very wide host range with at least 60 host plants being known in Florida and perhaps 700 worldwide. secondary transmission within crops where colonization occurs. M.R.Srinivasan et.Al., 423–424. Melon aphid can complete its development and reproduce in as little as a week, so numerous generations are possible under suitable environmental conditions. Appearance of Aphis gossypii Glover and Aphis spiraecola Patch (Rhynchota: Aphidoidea) on avocado, persimmon and macadamia. Melon aphid occurs in tropical and temperate regions throughout the world except northernmost areas. Figure 5. The biggest ecosystem level threat might be its ability to transmit plant viruses. In hot conditions or when crowded they are … Light colored mulches (e.g., silver, white) reflect short-wave light, repelling flying aphids. Melon or cotton aphid. Information in this database comes from published articles. Host Plants: polyphagous, especially cotton and Cucurbits. Romanow LR, Moyer JW, Kennedy GG. Author information: (1)Department of Entomology, Nanjing Agricultural University, Nanjing, China. [1], Carbamates and organophosphates are commonly used against A. gossypii around the world. One other species commonly encountered is A. spiraecola Patch, the spirea aphid. Cotton aphid, Melon aphid.. Distribution. The closely related Aphis gossypii (cotton or cucumber aphid) is a cosmopolitan polyphagous pest of warm climates, and is a greenhouse pest in cooler climates. thorough cover of foliage. As noted above, it is difficult to disrupt transmission of nonpersistent A field experiment was conducted during the kharif season of 1997-98 in Tamil Nadu, India to evaluate the bioefficacy of carbosulfan 25 EC, bifenthrin 10% WP and Neemitaf (a neem-based product) against the carmine spider mite Tetranychus cinnabarinus and the aphid Aphis gossypii. This is the basis for the common name melon aphid. Winged adult (yellow morph) melon aphid, Aphis gossypii Glover. Fungi also are sometimes observed to affect melon aphid. 1992. Wingless adult (yellow morph) melon aphid, Aphis gossypii Glover. Late in the season, winged females apparently seek primary hosts, and eventually both males and egg-laying (oviparous) females are produced. [1] The nymphs vary in colour, being shades of green, tan and gray. It is cosmopolitan in habitat. Oil is postulated to inhibit virus acquisition and transmission by preventing virus attachment to the aphid's mouthparts, or to reduce probing behavior. Early in the season, aphid infestations are often spotty, and if such plants or areas are treated in a timely manner, great damage can be prevented later in the season. These values vary considerably, mostly as a function of temperature. They mate and females deposit yellow eggs: eggs are the only overwintering form under cold conditions. A new distribution map is provided for Aphis gossypii Glover (Doralis frangulae[Aphis frangulae] Kalt., Cerosipha gossypii[Aphis gossypii] (Glov.)) 2001. Photograph by P.M. Choate, University of Florida. They may feed, mature, and reproduce parthenogenetically (viviparously) on this host all summer, or they may produce winged females that disperse to secondary hosts and form new colonies. The body is dull in color because it is dusted with wax secretions. ... Aphis gossypii - 2019. [4], In the southern half of the US, as far north as Arkansas, sexual reproduction of the cotton aphid is not important. amphlexicaule; boneset, Eupatorium petaloiduem; and citrus, Citrus spp. Effect of synergist to breakdown the neonicotinoid resistance in cotton aphid, Aphis gossypii (Glover) Abstract Cotton aphid, Aphis gossypii is an important sucking pest on cotton and other crops. ... T : Eect of TNAU neem oil on thrips damage in cardamom-Bodimettu, Bodi (mean of three observations). 1941. The two primary aphid species that result in fruit damage are the cotton aphid (Aphis gossypii) and another unidentified species referred to as the pomegranate aphid (Carroll 2010). In the United States, it is regularly a pest in the southeast and southwest, but is occasionally damaging everywhere. However, Sedum is not a host of melon aphid, but a closely related Castner, University of Florida. Fewer aphids land on crop plants growing in fields with reflective mulch (relative to bare soil). Other aphids are similar in appearance to Aphis gossypii (Glover), the melon or cotton aphid. Cucumber mosaic virus, watermelon mosaic virus 2, and zucchini yellow mosaic virus are transmitted despite applications of insecticide and oil sprays, probably because the viruses can be transmitted within 15 seconds. In the south, overwintering eggs are not commonly Vectored by aphids Aphis gossypii, A. craccivora and also spreads to cucurbits not through seeds. Capinera JL. Incidence of aphid-transmitted virus infections reduced by whitewash sprays on Coccinellids, spiders and lacewings are the most important predators of aphids and other pests in cotton fields. Several researchers have noted the existence of host races; for example, aphids reared on cotton could be transferred successfully to okra but not to cucurbits. Infesting tender shoots and under surface of the leaves; Curling and crinkling of leaves; Stunted growth; Blighted appearance when infestation is severe; Development of black sooty mould due to the excretion of honey dew giving the plant a dark appearance; Identification of the pest Figure 3. Its head and thorax are black, the abdomen yellowish-green with black lateral spots and the antennae are longer than those of the apterous female. It is a widely distributed pest of a variety of agricultural crops in the families Cucurbitaceae, Rutaceae and Malvaceae. 1940. (1996) published a key for cotton aphids that is also useful for distinguishing 1939. A. devastans and A. gossypii showed preference ratios of 1.51 and 1.17 respectively, towards bhendi, in TNAU IPM module whereas they did not prefer any intercrop in Guntur IPM module. Stoetzel MB, Miller GL, O'Brien PJ, Graves JB. Aphis gossypii and M. persicae are known to be capable of transmitting more than 75 plant viruses, and they are most versatile of insect vectors of plant viruses (Blackman & Eastop, 2000). 1941. The life cycle differs greatly between north and south. The dorsum has no dark sclerotized markings. The aphids' impact is especially important on vegetable crops such as courgette, melon, cucumber, aubergine and strawberry and on cotton, citrus and mallow. The wasp Lysiphlebus testaceipes (Cress) (Hymenoptera: Braconidae) is especially effective, sometimes causing up to 99% parasitism. species. California Agriculture 46: 35-39. Among cucurbit vegetables, it can seriously affect watermelons, cucumbers, cantaloupes, squash and pumpkin. Florida Entomologist 79: 193-205. Slosser E, Pinchak WE, Rummel DR. 1989. The Canadian Entomologist 70(9):183 >> Aphis gossypii; Blanchard, Everard Eel. Aphis gossypii is a tiny insect, an aphid ("greenfly") in the superfamily Aphidoidea in the order Hemiptera. Other vegetable crops attacked include pepper, eggplant, okra and asparagus. 1986. Both cause sooty mold and soft rot to occur where fruit share common surfaces (Day and Wilkins 2011). The nymphal period averages about seven days. Leaf distortions caused by aphid feeding provide excellent shelter for the insects, so systemic insecticides are useful. Physis 17:917 >> Aphis gossypii; Ghulamullah. viruses with insecticides, so total dependence on insecticides is not advised. However, the taxonomy of this species is uncertain, so some records may be incorrect. [2] Common names include cotton aphid, melon aphid and melon and cotton aphid. Read more... Aphis gossypii (Melon aphid, Cotton aphid) Wingless females of Aphis gossypii are usually medium-sized and blackish green or green mottled with dark green (see first picture below). Raise sorghum / maize as barrier crop before planting papaya. 1. Aphis gossypii Glover (Hemiptera: Aphididae) is a destructive pest of numerous crops worldwide. parthenogenetically in about seven days. Also, some plants may be damaged by oil applications, especially during hot weather. If insecticides are used to suppress melon aphid, care should be taken to obtain Among cucurbit vegetables, it can be a serious pest on watermelon, cucumber, and cantaloupe, and to a lesser degree squash and pumpkin. It also affects citrus, cotton and hibiscus. [1] As autumn approaches, the winged forms migrate back to the primary hosts. A.E. Research reveals pattern of cucurbit virus spread. The foliage may become chlorotic and die prematurely. Information is given on the geographical distribution in EUROPE (excl. 2007). This inability to transfer to other hosts has subsequently has been shown for several other combinations. In the south, and at least as far north as Arkansas, sexual forms are not important. If continuous cropping is implicated in retention of aphid populations then a crop-free period is needed. During heavy infestations, plant vigor is greatly reduced. Rogue out affected plants immediately on noticing symptoms. When disease inoculum or aphid densities are at high levels, oils may be inadequate protection. Though probably not practical in most vegetable cropping environments because of the potential for plant injury, sturdy vegetable plants in the home garden can benefit from spraying with water. It is a widely distributed pest of a variety of agricultural crops in the families Cucurbitaceae, Rutaceae and Malvaceae. Other aphids are similar in appearance to Aphis gossypii (Glover), the melon or cotton aphid. In Europe it reproduces exclusively by asexual reproduction and can produce nearly fifty generations a year under favourable conditions. They damage sweetpotato plants by sucking sap from growing shoots causing wrinkling, cupping, and downward curling of young leaves. One means of identifying them is by examining the cauda. Rather, catalpa, Catalpa bignonioides, and rose of sharon, Hibiscus syriacus, were the overwintering hosts in northern locations. Castner, University of Florida. The body is Common names. Also, crops grown down-wind from infested fields are especially susceptible because aphids are weak fliers and tend to be blown about. 729 pp. Transmission of nonpersistent viruses such as cucumber mosaic virus can sometimes be reduced by coating the foliage with vegetable or mineral oil. Under high density conditions, deterioration of the host plant, or upon arrival of autumn, production of winged forms predominates. Figure 4. The life span of a parthenogenic female is about twenty days in which time it can produce up to 85 nymphs. The foliage may become chlorotic and die prematurely. whitewash sprays, and reflective mulches or coarse net covers are helpful in delaying or reducing The apices of the femora, tibia and tarsi are black. The overwintering, or primary, host in cold climates was long thought to be limited to live-forever, Sedum purpureum.
