The study found endosulfan as the best choice for aphid control. Of the several naturally occurring parasites and predators, green lacewing (Chrysopa carnea) and two spotted lady beetle (Adalia bipunctata) have shown a potential to control cotton aphids, (Aphis gossypii), which are known to transmit cucumber mosaic virus (CMV) to many of their host plants.

Leaves may turn yellow and on ornamentals the large amounts of honeydew and exuvia may look unsightly. Conformance level of PDF/A standard 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). the chemical control of A. gossypii is an important issue in agriculture as this pest can severely decrease yield and quality in cultivated cotton. Melon aphid occurs in tropical and temperate regions throughout the world except northernmost areas. Production of yellow dwarfs in Aphis gossypii is very different from dwarfing produced through lack of nutrition. The use of the entomopathogenic fungus Beauveria bassiana significantly reduced CABYV transmission rate (González-Mas et al., 2019). The biological pest control agent, B. bassiana, showed somewhat insecticidal activities against the cotton aphid, Aphis gossypii, too.
