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). part Text Which reminds me, I ought have said why our initial identification was Introduction.
