摘要
佯死被认为主要是作为一种躲避捕食者的行为进化而来的,在 31 个昆虫目中有 10 个目有过佯死的报道。然而,目前还没有关于鞘翅目昆虫佯死行为的报道。我们发现,两种蝎蝇(Panorpa japonica 和 P. pryeri)的幼虫在受到外部刺激时,会通过刷戳刺激表现出佯死行为。首先,我们研究了装死姿势的频率。这两个物种表现出两种不同的佯死姿势,即 "直 "和 "球"。大多数粳稻和杓鹬的1龄幼虫都采用了 "直 "佯死姿势。接下来,我们研究了佯装死亡的持续时间。随着幼虫龄期的增加,两种Panorpa的佯死姿势都从直的转变为球的。在 P. japonica 中,死亡假动作持续时间最长的是 2-3 龄幼虫,而在 P. pryeri 幼虫中,死亡假动作持续时间最长的是 4 龄后期。
Death Feigning in Larvae of Scorpionflies (Mecoptera: Panorpidae): Frequency and Postural Changes Based on Larval Instars
Death feigning is thought to have evolved primarily as a predator avoidance behavior, and has been reported in 10 of the 31 orders of insects. However, there have been no reports of death-feigning behavior in Mecoptera species. We found that larvae of two scorpionfly species, Panorpa japonica and P. pryeri, showed death feigning in response to external stimuli by brush poking stimulation. First, we examined the frequencies of death-feigning postures. The two species showed two different postures of death feigning, “straight” and “ball.” Most of the 1st instar larvae of P. japonica and P. pryeri adopted the straight death-feigning posture. Next, we examined duration of death feigning. As the larval instar progressed, the death-feigning posture shifted from straight to ball in both Panorpa species. In P. japonica, the longest durations of death feigning were found in the 2nd to 3rd instars, while the longest duration of death feigning was found in the late 4th instar in P. pryeri larvae.
