Abstract
Laboratory bioassay was conducted to evaluate the efficacy of Ginkgo biloba L.leaf crude extracts against striped stem borer (SSB), Chilo suppressalis (Lepidoptera:Pyralidae). The results showed that the extracts had a strong oviposition deterrent to SSB moth, 72 h after treatment with 1.25 g/L concentration, the deterrent rate reached 61.67%. In choice and nonchoice tests, the antifeeding medium concentration (AFC50) of the extracts against SSB larvae in 2nd instar were 2.3 ,3.8 g/L, respectively. The extracts also showed an obvious growth inhibition activity to the larvae, and the extracts presented some insecticidal activity to the neonate of SSB.
