Effect of selected compounds from the group of chitin synthesis inhibitors on insects of sanitary importance

The effect of three aryl and heteroaryl dichlorobenzoylurea compounds as insect chitin inhibitors on sanitary important insects were investigated. These compounds were given insects: larvae and adults flies (Musca domestica) and cockroaches (Blattella germanica) with food. The best results on flies were after exposition to AG-6 and on cockroaches to AG-5. AG-6 complete inhibited metamorphosis after exposition of larvae and after exposition of adults in generation F1. No mature cockroaches from larvae exposed to AG-5, no hatching from cocoons lied by treated adults were observed.
