Abstract:As a single parasitic,capacitive parasitic wasp,Meteorus pulchricornis has a wide range
of hosts and can parasitize a variety of larvae of large lepidopteran pests exposed to food.The parasitic wasp
has excellent biocontrol value.Under the premise of effectively controlling the vegetable pest bases,it also
has the advantages of environmental friendliness,target specificity,human and animal safety,etc.It is an
important biological control resource.Host identification behavior is the key link of parasitic wasps in making
parasitic decisions to the host.Understanding the host recognition behavior of parasitic wasps is of important
significance for the synergistic application of parasitic wasps and the other pathogens,prevention and control of
pest dominant populations,and protective utilization of parasitic wasps,etc.This paper reviews the factors
affecting M. pulchricornis in host recognition,so as to provide references for productive application of M.
pulchricornis and enhancing biocontrol value of vegetable pests,etc.The paper also prospects the direction of
future research activities.
