摘要

摘要/ ABSTRACT摘要:研究了普克科河马铃薯作物中2种本地和3种外来捕食昆虫防治番茄马铃薯木虱的潜力;在无选择和选择贪婪实验室分析中评估TPP。研究了不同生活期小圆蚧与桃蚜的食蚜率和捕食能力。褐草蛉(Micromus tasmaniae)、小食蚜蝇(Melanostoma fasciatum)、太平洋豆小虫(Nabis kinbergii)、11斑瓢虫甲虫(Coccinella十一孔瓢虫)和大斑瓢虫甲虫(Harmonia conformis)这5种物种即使在蚜虫存在的情况下，也会吃掉cockerelli的所有生命阶段。在无选择试验中，除金伯氏乳杆菌外，所有捕食者对cockerelli卵的偏好程度最低。两种常见的本地捕食者，塔斯马尼斯田鼠和筋膜田鼠，在最小的生命阶段都能在24小时内吃掉12个以上的小cockerelli若虫。在天敌保护的作物中，这些物种可能是cockerelli的重要天敌。

The voracity of five insect predators on Bactericera cockerelli (Sülc) (Hemiptera: Triozidae) (tomato potato psyllid; TPP)

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.

期刊介绍： The invertebrate diversity of New Zealand is of great interest worldwide because of its geographic isolation and geological history. The New Zealand Entomologist plays an important role in disseminating information on field-based, experimental, and theoretical research. The New Zealand Entomologist publishes original research papers, review papers and short communications. We welcome submissions in all aspects of science regarding insects and arthropods in a New Zealand or Australasian setting. The journal’s subject matter encompasses taxonomy, phylogenetics, biogeography, biological control and pest management, conservation, ecology and natural history. The journal is the official publication of the Entomological Society of New Zealand. Papers published or submitted elsewhere for publication will not be considered, but publication of an abstract or summary elsewhere (e.g. conference proceedings) does not preclude full publication in the New Zealand Entomologist. Accepted papers become copyright of the Entomological Society of New Zealand. The journal is published in English, but we also welcome publication of abstracts in Maori.
