摘 要：Larvae of some leaf beetles carry masses of feces covering parts or all of the body,which is called afecal shield In general,the shield is thought to be a defense structure against natural ***,some studies have suggested that defense effectiveness varies depending on the natural *** this study,we used a fecal retention leaf beetle Ophrida xanthospilota(Coleoptera:Chrysomelidae),and 2 local generalist predators(an ant,Camponotus japonicus(Hymenoptera:Formicidae)and a stinkbug,Arma custos(Hemiptera:Pentatomidael)as a system to test the hypothesis that the fecal shield of *** plays different roles in predation behavior of different predators and can provide multiple chemical communication signals in predator-prey *** bioassays showed that the fecal shield of *** larvae repelled the ant *** while attracting the stinkbug *** results also strongly demonstrated that hexane extracts of the fecal shield significantly repelled ***,while dichloromethane(DCM)extracts did not inhibit ant ***,DCM extracts attracted ***,but hexane extracts did ***,we suggest that the fecal shield is a double-edged sword for the larvae of *** results also indicated that the risk-benefit tradeoff of an insect should be estimated at a community level involving multiple enemies(predators and parasites)and herbivores,rather than in a single prey-predator pair.
