Abstract The invasive container-dwelling mosquito Aedes albopictus (Skuse) shows modest behavioral responses to water-borne cues from predatory Corethrella appendiculata Grabham in North America. We investigate whether Ae. albopictus adjust their antipredatory responses to be proportional to size-dependent risk of predation. Fourth-instar Ae. albopictus attain a size refuge from C. appendiculata predation, and we compared the responses of second- and fourth-instar Ae. albopictus to cues from C. appendiculata predation. More vulnerable second-instar larvae showed a larger change in behavior in response to predation cues than did less vulnerable fourth-instar larvae, indicating threat-sensitive behavioral responses by Ae. albopictus.

白纹伊蚊对捕食者的行为反应与大小相关的捕食风险相关

摘要 侵入性容器居住蚊子白纹伊蚊 (Skuse) 对北美掠食性 Corethrella appendiculata Grabham 的水传播线索表现出适度的行为反应。我们调查是否 Ae。albopictus 将它们的反捕食反应调整为与大小相关的捕食风险成正比。四龄 Ae。albopictus 从 C. appendiculata 捕食中获得了一个大小避难所，我们比较了二龄和四龄 Ae 的反应。albopictus 从 C. appendiculata 捕食的线索。与较不脆弱的四龄幼虫相比，更脆弱的二龄幼虫在对捕食线索的反应中表现出更大的行为变化，表明 Ae 对威胁敏感的行为反应。白线虫。
