After the discovery of Du 19111, many hundreds of related benzoylphenyl ureas were synthetized and screened with respect to larvicidal activity. 

We knew that a shift of at least one chlorine atom from the ortho-position to the meta- or para-position resulted in much more soil-degradable benzamides but this could not be applied here, because we had learned from other QSAR studies with the benzoylphenyl ureas mentioned earlier that the 2,6-position of the(chlorine)substituents was essential for a high larvicidal activity. 

Cinnamon oil exhibited fumigant toxicity to adults of Acanthoscelides oblectus and inhibited its reproduction through ovicidal and larvicidal action. Both cinnamaldehyde and cinnamyl alcohol showed ovicidal and larvicidal activity (Roger and Hamraoui, 1994). Cinnamaldehyde possessed antifeedant activity against Ceratitis capitata, a pest causing damage to fruit crops (Moretti et al., 1998).

Thiadiazine insecticides are derivatives of thiadiazine. Buprofezin is the only current member of this group. It is an insecticide with persistent larvicidal activity against sucking insects such as mealybugs, rice planthoppers, scales, and whiteflies in rice, potatoes, citrus, cotton, and vegetables. Its oral LD50 in rats is 2198 mg/kg.

Structure-activity relationships were defined in the house fly for a series of highly fluorinated and larvicidally active N,2-diphenylhydrazinecarbox-amides. The most effective larvicide identified from the study was Hi, 2-(2-fluorophenyl)-N-[2-(trifluoro-methyl)phenyl]-hydrazinecarboxamide. Compound completely inhibited larval development at 1-5 ppm in the diet. As a part of this study, nine related diazenecarboxamides were synthesized and evaluated.
