中文摘要:为明确红颈常室茧蜂Peristenus spretus Chen et van Achterberg定位寄主绿盲蝽Apolygus lucorum（Meyer-Dür）时利用的挥发性信息物质来源，利用Y型昆虫嗅觉仪测定了红颈常室茧蜂雌雄成虫对绿盲蝽3龄若虫及其为害寄主植物棉株以及雌性红颈常室茧蜂成虫、绿盲蝽成虫对苗期和花期的棉花、蓖麻的选择行为。结果表明，与干净空气（空白对照）相比，雌性红颈常室茧蜂对绿盲蝽3龄若虫、健康棉株的选择行为无显著差异，绿盲蝽3龄若虫为害的棉株对雌性红颈常室茧蜂具有显著的吸引作用,但在为害后去虫和未去虫处理间无显著差异；雄性红颈常室茧蜂对各处理均无明显的选择行为。与健康或为害后去虫的苗期棉花相比，雌性绿盲蝽成虫显著趋向花期蓖麻；而雌性红颈常室茧蜂只趋向于为害后的花期蓖麻。雌性红颈常室茧蜂对为害后去虫的花期棉花和花期蓖麻的选择行为显著高于相应的苗期植株。这表明雌性红颈常室茧蜂主要利用绿盲蝽若虫为害后寄主植物释放的挥发性信息物质来定位寄主绿盲蝽，且其对花期寄主植物的选择行为与绿盲蝽成虫具有一致性。

Abstract:To clarify the source of volatiles used by parasitoid Peristenus spretus Chen et van Achterberg (Hymenoptera: Braconidae) to locate the nymphs of green mirid bug Apolygus lucorum (MeyerDür) (Hemiptera: Miridae), behavioral selection of P. spretus to A. lucorum nymphs and its damaged cotton plants, vegetative and flowering cotton and castor bean plants were measured by using Y-tube olfactometer in this study. The results showed that the 3rd instar A. lucorum nymphs, and healthy cotton plants had no significant attraction to female P. spretus. Female wasps were significantly attracted to damaged cotton plants (both with and without mirid nymphs), but no difference was found between these two treatments. However, male P. spretus showed no markedly preference to any above mentioned treatments. In addition, compared with healthy and damaged but with nymphs removed vegetative cotton plants, female A. lucorum adults were significantly attracted to flowering castor bean plants in the same treatment, whereas female wasps only preferred damaged flowering castor bean plants but not healthy ones. Furthermore, female P. spretus preferred damaged flowering cotton and castor bean plants (with mirid nymphs removed) to the corresponding vegetative host plants. The results indicated that female P. spretus mainly utilizes the volatiles from host plants damaged by A. lucorum, and the behavioral selection of female P. spretus to flowering host plants was consistent with that of A. lucorum.
