INNFLUENCE OF BENZOYLPHENOL INSECTICIDES AND THEIR ACTION MECHANISMS ON APRIONA GERMARI ADULTS

The adults of Apriona germari were fed in rooms with insecticides of benzoylphenol No.3 and triflumuron. The results showed that there was no obvious effect on the morphology of the internal reproductive system of the adult insects. The ultrastructure of the sperms of male A. gremari was observed and clearly defined by using electron microscope. Benzoylphenol No.3 can obviously decrease the sperm amount and cause sperm structure malformation, and there were no obvious effects on eating behaviour and life span, and some obvious effects were found on egg amount laid in the early stage of the adults, but there was no significant effect on the total egg amount laid. However, benzoylphenol No.3 and triflumuron treatments could decrease the egg incubation rates to 39.92%～48.82% and 74.33%～100%, respectively.
