ABSTRACT
Diamondback moth (Plutella xylostella) is the most destructive pest on Brassicaceae plants family around the world. The present study investigated the feeding selection behavior of diamondback moth larvae with an approach to the acetone extract effects of Salvia Miltiorrhiza Bunge (SMB). It was found that acetone extracts of Salviami ltiorrhiza Bunge (SIB) represented by cryptotanshinone and dihydrotanshinone had lethal effect on diamondback moth larvae, and the correlation coefficient was 0.972. Through further antifeedant test, it was found that diamondback moth larvae had obvious antifeedant behavior to acetone extracts of SIB represented by cryptotanshinone and dihydrotanshinone, and the correlation coefficient was -0.915. By further observing the influence of acetone extract of SIB on the feeding selection behavior of diamondback moth larvae, it was found that diamondback moth larvae had obvious avoidance behavior towards acetone extract of SIB. Therefore, it can be considered that acetone extract of SIB can affect the feeding behavior of diamondback moth insects because of its biological effects such as dihydrotanshinone and cryptotanshinone. This effect is firstly fatal to diamondback moth larvae after feeding, and may also cause antifeedant and aversion of diamondback moth larvae.
