ABSTRACT The potential of two native and three exotic insect predators residing in potato crops at Pukekohe to control Bactericera cockerelli (tomato potato psyllid; TPP) was assessed in no-choice and choice voracity laboratory assays. Rates of consumption and ability to predate on different life stages of B. cockerelli compared with the aphid species Myzus persicae were examined. All five species, brown lacewing (Micromus tasmaniae), small hoverfly (Melanostoma fasciatum), Pacific damsel bug (Nabis kinbergii), 11-spotted ladybird beetle (Coccinella undecimpunctata) and large spotted ladybird beetle (Harmonia conformis) ate all life stages of B. cockerelli even in the presence of aphids. Eggs of B. cockerelli were the least preferred by all predator species except for N. kinbergii in no-choice assays. The smallest tested life stages of each of the two commonly occurring native predators, M. tasmaniae and M. fasciatum, were capable of eating more than 12 small B. cockerelli nymphs in 24 h. These species may be expected to be important natural enemies of B. cockerelli in crops where natural enemies are conserved.

五种昆虫捕食者对可卡氏杆菌（Sülc）（半翅目：Triozidae）（番茄马铃薯木虱；TPP）的贪婪

摘要 在无选择和选择贪婪实验室测定法中评估了居住在 Pukekohe 马铃薯作物中的两种本地和三种外来昆虫捕食者控制公鸡杆菌（番茄马铃薯木虱；TPP）的潜力。检查了与蚜虫物种桃蚜相比，公鸡不同生命阶段的消耗率和能力。所有五个物种，棕色草蛉（Micromus tasmaniae）、小型食蚜蝇（Melanostoma fasciatum）、太平洋少女蝽（Nabis kinbergii）、11 点瓢虫（Coccinella undecimpunctata）和大型斑点瓢虫（Harmoniaconformis）都吃掉了 B 的所有生命阶段. cockerelli 即使在蚜虫存在的情况下。在无选择试验中，除了金氏猪笼草外，所有捕食者物种最不喜欢 B. cockerelli 的卵。两种常见的本地捕食者 M. tasmaniae 和 M. fasciatum 中每一种的最小测试生命阶段都能够在 24 小时内吃掉超过 12 只小型 B. cockerelli 若虫。在保护天敌的作物中，这些物种可能是公鸡的重要天敌。
