在猎物孵化后的不同天数，将新孵化的三色伊蚊幼虫加入实验种群，以检验发育不同步的假说。Triseriatus和Tx.金龟子通过Ae逃避捕食。小水体中的三栖动物。Tx的存在。粉虱对猎物存活率有显著影响。存活率[log10(x+1)转换]与猎物头部开始的天数的回归得到了一个很小但显著的正斜率，表明随着头部开始的天数的增加，存活率略有增加。对于雌性，羽化时的平均体重不受处理的显著影响；然而，不同处理之间羽化的中位数天数有显著差异，雌性羽化所需的时间明显长于Tx。当捕食者出现时，红蜘蛛不在。对于雄性，平均体重和中位羽化天数都不受处理的显著影响。治疗对Tx的死亡频率或平均重量没有显著影响。因此，Tx之间的发育不同步。Rutilus和Ae.三栖类对捕食者没有影响，但在高孵化密度下对猎物的性能有微弱的影响。
Newly hatchedToxorhynchites rutilus(Coquillet) were added to experimental populations ofAedes triseriatus(Say) at varying days after prey hatch to test the hypothesis that a developmental asynchrony ofAe. triseriatusandTx. rutilusleads to escape from predation byAe. triseriatusin small water bodies. Presence ofTx. rutilussignificantly affected prey survivorship. Regression of survivorship [log10(x + 1) transformed] versus days head start for prey yielded a small, but significant positive slope, indicating that survivorship increased slightly with an increasing number of days head start. For females, mean weight at emergence was not significantly affected by treatments; however, median days to emergence differed significantly between the treatments, with females taking significantly longer to emerge withTx. rutilusabsent than when the predator was present. For males, neither mean mass nor median days to emergence was significantly affected by treatments. Treatments had no significant effect on the frequency of deaths or on mean weight ofTx. rutilus.Thus, a developmental asynchrony betweenTx. rutilusandAe. triseriatusappears to have no effects on the predator, but does have a weak effect on prey performance at high hatch densities.
