采用选择试验研究了4种食蚜瓢虫和2种草蛉的产卵忌避幼虫迹对4种瓢虫雌虫的影响。食蚜性瓢虫Cycloneda limbifer凯西（Casey）、十一点瓢虫Semiadalia undecimnotata（Schneider）和七星瓢虫Coccinella septemunctata L.在有未取食的同种1龄幼虫足迹的地点产卵量显著低于干净地点，但Leisdimidiata（F.）在两个地点产卵的数量相似。在一些但不是所有的物种中，异种捕食者的踪迹也阻止了瓢虫的雌性。异域种间的种间效应强于同域种间。septempunctata和S. undecimnotata。C.在以前接触过的地点，缘栖动物产卵相对较少。undecimnotata和L.二瓣的S. undecimnotata避开了L.双翅幼虫两个较小的种C. limbifer和S. undecimnotata的产卵量显著低于较大的瓢虫，C. septempunctata和L.二瓣的C. limbifer和S. undecimnotata在干净的地点和有草蛉幼虫足迹的地点产卵的数量相似。雌性C. septempunctata产卵较少的网站先前暴露于幼虫的C。oculata而不是C.在一次选择试验中，瓢虫雌虫在干净和有捕食性幼虫足迹的基质上的粪斑密度差异显著（C.雌性缘栖动物暴露于S. undecimnotata幼虫）。这表明幼虫足迹的存在对雌性产卵的影响大于它们搜索的地方。
The effects of oviposition-deterring larval tracks of four aphidophagous coccinellids and two chrysopids were investigated on females of four coccinellid species in choice tests. Aphidophagous coccinellids Cycloneda limbifer Casey, Semiadalia undecimnotata (Schneider) and Coccinella septempunctata L. laid significantly fewer eggs on sites with tracks of unfed conspecific first instar larvae than on clean sites, but Leis dimidiata (F.) laid similar numbers of eggs on both sites.In some but not all species, tracks of heterospecific predators also deterred coccinellid females. Interspecific effects were stronger between some allopatric species than between the sympatric coccinellids C. septempunctata and S. undecimnotata. C. limbifer laid relatively few eggs on sites previously exposed to larvae of S. undecimnotata and L. dimidiata. S. undecimnotata avoided sites with tracks of L. dimidiata larvae. The two smaller species, C. limbifer and S. undecimnotata, laid considerably fewer eggs per batch than the larger coccinellids, C. septempunctata and L. dimidiata. C. limbifer and S. undecimnotata oviposited similar numbers of eggs on clean sites and sites with tracks of chrysopid larvae of the species Chrysopa oculata and Chrysopa perla. Females of C. septempunctata laid fewer eggs on sites previously exposed to larvae of C. oculata but not C. perla.Densities of faecal spots of coccinellid females on clean substrates and substrates with tracks of predatory larvae differed significantly in only one choice test (C. limbifer females exposed to tracks of S. undecimnotata larvae). This indicates that the presence of larval tracks affects where females lay eggs more than where they search.
