We examined population dynamics of one-parasitoid-two-host systems, using pteromalid wasp (Anisopteromalus calandrae) and two bruchine hosts (Callosobruchus chinensis, C. maculatus). The resource seeds are provided in combination with the azuki and the black-eye beans, so that we could adjust the predation pressure. Introducing the parasitoid greatly enhanced the coexistence time, to a maximum of 118 weeks, where C. maculates and C. chinensis showed anti-phase oscillations. The parasitoid performed frequency-dependent predation on two host species and switched the preference depending on their abundance. Learning experiments confirmed the frequency-dependent predation of A. calandrae with olfactory cue. The parasitoid increased their preference for the common host species, which results in three-species coexistence for a long time.

我们以金小蜂（Anisopteromalus calcium）和两种豆象宿主（Callosobruchus chinensis、C.斑）。将资源种子与红豆、乌眼豆组合提供，以调节捕食压力。寄生蜂的引入大大延长了寄生蜂的共存时间，最长可达118周。maculates和C. chinensis表现出反相振荡。该寄生蜂对两种寄主进行频率依赖性捕食，并根据其丰度切换偏好。学习实验证实了A.有嗅觉提示的大脑。寄生蜂对共同寄主的偏好性增强，导致三种寄生蜂长期共存。
