Abstract

The present study describes the feeding effects of Neoseiulus cucumeris Athias-Henriot (Acari: Phytoseiidae) on western flower thrips (WFT), Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae) and two-spotted spider mite (TSSM), Tetranychus urticae Koch (Acari: Tetranychidae). In addition, daily and total predation capacity, preference, and prey switching potential of this predator were studied on both pest species. WFT had a boosting effect on the biological parameters of N. cucumeris, primarily resulting in shorter developmental time, higher fecundity, and higher population growth potential than TSSM. Although immatures and males of N. cucumeris consumed significantly more TSSM than WFT, there was no significant difference in net predation rate, stable and finite predation rates of the predator between two prey species. We found an average of 10.58 and 7.93 TSSM and WFT are required to produce a single predator egg, respectively. WFT is preferred over TSSM by the predator. Negative switching behaviour was seen in N. cucumeris as it switched from the abundant prey to the rare prey. Both prey species were suitable for N. cucumeris, being able to develop successfully on them. The predator performed optimally on WFT compared with TSSM owing to its enhanced biological parameters as well as its preference, indicating that thrips are a more relevant resource than spider mites.

黄瓜新绥螨捕食性螨对双斑蜘蛛螨和西花蓟马的效果定量评价。

本文研究了黄瓜新绥螨（neseiulus cucumeris Athias-Henriot）（蜱螨亚纲：植物绥螨科）对西部花蓟马（WFT）、西Frankliniella occidentalis（恙螨亚纲：蓟科）和两斑蜘蛛螨（TSSM）、荨麻叶螨（螨亚纲：叶螨科）的取食效果。此外，还对两种害虫的日捕食量、总捕食量、偏好和猎物转换势进行了研究。与TSSM相比，WFT对黄瓜乳螨的发育时间更短，繁殖力更高，种群生长潜力更大，对黄瓜乳螨的生物学指标有促进作用。黄瓜小蠊的净捕食率、稳定捕食率和有限捕食率均无显著差异，但幼虫和雄虫对TSSM的消耗显著高于WFT。我们发现，产生一个捕食者卵平均需要10.58和7.93 TSSM和WFT。捕食者更喜欢WFT而不是TSSM。黄瓜N.黄瓜在从丰富的猎物到稀少的猎物的转换过程中表现出负转换行为。这两种猎物都适合黄瓜乳杆菌，能够成功地在它们身上发育。与TSSM相比，食肉动物在WFT上的表现最佳，这是由于其生物学参数的增强以及对TSSM的偏好，表明蓟马是比蜘蛛螨更相关的资源。

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.
