Abstract:The active chemicals in the saliva of the maize weevil, Sitophilus zeamais Motschulsky, that elicit the production of wheat volatiles was investigated. Our results demonstrated that the Lariophagus distinguendus females, irrespective of experience, were apparently attracted by the odors released from wheat induced by the saliva of the weevil larvae that never have been applied in previous researches. Moreover, we compared the responses of female parasitoids to odors released from wheat induced by protein substances of regurgitant and non-protein substances. Further experiments revealed that volatiles attracting parasitoid L. distinguendus are possibly induced by the some protein substances from weevil larvae saliva. The effect of experience on the response of the parasitoids to several stimuli was discussed.
