Chemical design and bioefficacy screening of new insect growth regulators as potential insecticidal agents against Spodoptera littoralis (Boisd.)

Abstract The 13 new compounds were chemically synthesized and their spectroscopic analysis was done to determine their chemical structure. All the compounds were screened for their insecticidal potential against Spodoptera littoralis (Boisd.). Among the tested compounds, the compound 13 was found to be the most potent. It displayed one fold more activity than a reported insect growth regulator, fenoxycarb. The other target compounds demonstrated weak to strong toxicological activities against Spodoptera littoralis (Boisd.).
