Abstract

The predator Chrysoperla externa (Neuroptera: Chrysopidae) has great potential for its use in biological pest control programs. In order to assist future biological control programs that use Chrysopidae as a control agent, this research aims to study the behaviour of the green lacewing, C. externa, consuming two-spotted spider mites, Tetranychus urticae (Acari: Tetranychidae). In the laboratory, experiments were carried out to determine the predation behaviour of C. externa on different densities of adults of the two-spotted spider mite, T. urticae (1, 2, 4, 8, 16, 32, and 64 prey). For comparison purposes, the behaviour of C. externa was also studied using eggs from the alternative prey Ephestia kuehniella (Lepidoptera: Pyralidae). The functional response was determined by logistic regression of the number of mites consumed as a function of the initial number of prey using polynomial logistic regression. The random equation was used to describe the parameters of the functional response. The predator C. externa showed a type II functional response consuming both E. kuehniella eggs and T. urticae adults. The results obtained will allow to define the best strategy for the use of green lacewings in the biological control of the two-spotted spider mite, T. urticae.

捕食者外茧蝇（Chrysoperla externa，神经翅目：茧蝇科）在生物害虫防治中具有很大的应用潜力。本研究旨在研究绿草蛉（C. externa）对荨麻叶螨（Tetranychus荨麻叶螨，螨亚纲：叶螨科）的捕食行为，为今后以叶螨为防治剂的生物防治提供依据。在实验室中，研究了外生革螨对不同密度双斑螨成虫（1、2、4、8、16、32和64个猎物）的捕食行为。为了进行比较，我们还利用可选择的猎物库氏Ephestia kuehniella（鳞翅目：Pyralidae）的卵研究了外蠓的行为。利用多项式逻辑回归方法，将捕获螨的数量作为初始猎物数量的函数进行逻辑回归，确定了功能响应。采用随机方程来描述功能响应参数。捕食者外生伊蚊对库氏伊蚊卵和荨麻疹伊蚊成虫均表现出II型功能反应。所得结果将有助于确定绿草蛉生物防治荨麻疹双斑蜘蛛螨的最佳策略。

期刊介绍： Established in 1910, the internationally recognised Bulletin of Entomological Research aims to further global knowledge of entomology through the generalisation of research findings rather than providing more entomological exceptions. The Bulletin publishes high quality and original research papers, ''critiques'' and review articles concerning insects or other arthropods of economic importance in agriculture, forestry, stored products, biological control, medicine, animal health and natural resource management. The scope of papers addresses the biology, ecology, behaviour, physiology and systematics of individuals and populations, with a particular emphasis upon the major current and emerging pests of agriculture, horticulture and forestry, and vectors of human and animal diseases. This includes the interactions between species (plants, hosts for parasites, natural enemies and whole communities), novel methodological developments, including molecular biology, in an applied context. The Bulletin does not publish the results of pesticide testing or traditional taxonomic revisions.
