abstract：:The diamondback moth (Plutella xylostella), a crucifer-specialist pest, has been documented to employ glucosinolates as host recognition cues for oviposition. Through the use of mutant Arabidopsis thaliana plants, we investigated the role of specific classes of glucosinolates in the signaling of oviposition by P. xylo...
