摘要

Significant predation of diaspidid scale insects occurs in unsprayed kiwifruit crops. Two predators, Forficula auricularia L. (Dermaptera: Forficulidae) and Halmus chalybeus (Boisduval) (Coleoptera: Coccinellidae) are likely to be important. Most F. auricularia were found as late instars or adults in the canopy of kiwifruit vines in late spring and early summer. Adults of H. chalybeus were present throughout the year but at lower densities on kiwifruit vines than on other host plants. In the field predation of scale insects occurred mainly at night and preferentially on late-instar scale insects consistent with the feeding behaviour of F. auricularia, not H.chalybeus. The latter mainly fed on early instar insects during the day. Numbers of scale insect crawlers were not correlated with numbers of F. auricularia or of H. chalybeus in kiwifruit vine canopies.

Chalybeus的成年人全年都存在，但在Kiwifruit葡萄藤上的密度低于其他宿主植物。 在规模昆虫的野外捕食中主要发生在夜间，优先对瞬间鳞片昆虫与F.Auricularia的饲养行为一致，而不是H.Chalybeus。 后者主要在白天早期龄昆虫喂食。 规模昆虫爬虫数量与Kiwifruit葡萄藤Canopies的F. Auricularia或H.Chalybe的数量没有相关。
