Abstract

Mirid bugs include polyphagous predators, which are used for augmentative biological control in the greenhouses to manage whiteflies, thrips and lepidopteran pests around the world. Nesidiocoris tenuis (Reuter) (Hemiptera: Miridae), which is indigenous to Japan, has recently been commercialised to control whiteflies and thrips. This predator species is expected to control both Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) and Thrips palmi Karny (Thysanoptera: Thripidae) on greenhouse-grown cucumbers in Japan. To examine the suppressive effects of N. tenuis against these two pest species, occurring in cucumbers, it is essential to clarify the prey selection between them. In this study, we examined the preference of N. tenuis between B. tabaci and T. palmi on cucumber leaf discs under controlled conditions. Nesidiocoris tenuis female adults preferred T. palmi larvae over B. tabaci nymphs. Preference for T. palmi larvae was weakest when the density ratio of B. tabaci to T. palmi presented to the N. tenuis female was highest. Neither the nymphal developmental stage of B. tabaci, nor predation experience in either prey species prior to the experiment, significantly affected prey selection. Nesidiocoris tenuis has excellent predatory characteristics for the control of T. palmi when it co-occurs with B. tabaci on cucumbers in greenhouses.

烟粉虱（半翅目：烟粉虱科）与棕榈蓟马（翅目：蓟马科）的取食偏好

Mirid臭虫包括多食性捕食者，它们在温室中被用于增强生物控制，以管理世界各地的白蝇、蓟马和鳞翅目害虫。nisidiocoris tenuis（路透社）（半翅目：Miridae），原产于日本，最近被商业化用于控制白蝇和蓟马。该掠食性物种有望防治日本温室黄瓜上的烟粉虱（半翅目：烟粉虱科）和棕榈蓟马（翅目：蓟马科）。为了研究黄瓜对这两种害虫的抑制作用，有必要明确它们之间的猎物选择。在控制条件下，研究了烟粉虱和棕榈粉虱对黄瓜叶盘的偏好。与烟粉虱若虫相比，烟粉虱雌成虫更喜欢棕榈螟幼虫。当烟粉虱与棕榈粉虱的密度比最高时，对棕榈粉虱幼虫的偏好最弱。烟粉虱的若虫发育阶段和实验前两种猎物的捕食经历对猎物选择都没有显著影响。在大棚黄瓜上与烟粉虱共生时，细纹螟具有优良的防治棕榈螟的捕食性。
