摘要 1978—79年在云南昆明、嵩明等地先后采到豌蚜的一种优势寄生天敌—阿尔蚜茧蜂。本文着重研究了几种主要环境因子对其生殖的影响。 食物是决定阿尔蚜茧蜂寿命的基本环境因子之一。饲以20%蔗糖液的雌蜂寿命最长可达20—21天。...展开更多 The present paper deals with the influence of environmental factors on ...
The braconid Aphidius ervi Haliday (Hymenoptera, Braconidae) is an endophagous parasitoid of the pea aphid, Acyrthosiphon pisum (Harris) (Homoptera, Aphididae). Parasitized host aphids show different degrees of castration, a response that is total when parasitoid oviposition takes place in first ...

Broad bean plants ( Vicia faba ) infested by the pea aphid, Acyrthosiphon pisum , play a key role in the in-flight orientation of the parasitoid Aphidius ervi , by producing host-induced synomones (HIS). These volatiles are herbivore-specific and are systemically released from insect-free par...

This study aims at evaluating whether the bacterial endosymbionts of the pea aphid, Acyrthosiphon pisum (Harris), may be of any nutritional importance to the endophagous braconid parasitoid Aphidius ervi Haliday. Aposymbiotic aphids, obtained by rifampicin treatment on artificial diet, were parasitize...
Adult size (in terms of dry weight; DW) and development time ( T p ) of the solitary parasitoid Aphidius ervi varied when reared in different nymphal instars of its host, apterous virginoparae of the pea aphid ( Acyrthosiphon pisum ). Parasitoid DW increased with an increase in the DW...
