The Aphis gossypii is a global problem for its pesticide resistance with substantial economic and ecological cost and a wide host range, including cotton and cucurbits. Some aphids have wings, but they are not strong fliers, and are more likely to be blown in the wind onto new crops. In the tropics it is a major pest of many crops including cotton, cucurbits, coffee, cocoa, peppers and okra.

Of those aphid species, Baker (2015) lists 8 as occurring in Britain (Show British list). Aphis gossypii is known to transmit at least 50 plant viruses. The 4 most common aphid species in greenhouse crops are the cotton aphid Aphis gossypii, the green peach aphid Myzus persicae, the potato aphid Macrosiphum euphorbiae and the foxglove aphid Aulacorthum solani. endstream With biological control you are ready to … Development and fecundity of Aphis gossypii (Glover) (Homoptera: Aphididae) on three Malvaceae hosts.

Control of whitefly, Trialeurodes vaporariorum and cotton aphid, Aphis gossypii in glasshouses by two isolates of the fungus, Verticillium lecanii.

When compared with a known susceptible population, the aphids were found to be resistant to pirimicarb. Development of biopesticides against A. gossypii is critical and will require a better understanding of the effects of plant secondary metabolites on aphid population dynamics. gossypii has largely relied on chemical pesticides. 10.1186/s41938-018-0065-9 Identification Technology Program, CPHST, PPQ, APHIS, USDA; Fort Collins, CO. In many crops, natural controls often can regulate the population below economic impact thresholds. A. gossypii is usually controlled with widespread application of chemical pesticides such as carbamates, neonicotinoids, pyrethroids, and organophosphates, but the indiscriminate and extensive use of these synthetic chemicals causes disruption of the biological control system and the emergence of strains resistant to many insecticides with several economic and health problems (Cao et al., 2008).
