【Abstract】 The host-searching kairomones of Bracon greeni exist in the mixture of lae, the frass and silk of Eublemma amabilis larvae. The active ingredients were successfully extracted by methanol, and could elicite antennation and oviposition probing of 52.5%, 40%, respectively. The laboratory studies showed that the kairomones are stable. The kairomones could increase the parasitising rate of Bracon greeni on the larvae of great wax moth, and it will be beneficial to enhance mass reproduction of the parasites.更多还原
