中文摘要:研究了温度和寄主植物与寄生蜂密度对瓢虫柄腹姬小蜂PediobiusfoveolatusCrawford功能反应的影响。结果表明 瓢虫柄腹姬小蜂对自身密度的干扰反应均符合Watt所提出的模型 (A =aP-b)。在19~ 31℃ 5个温度下 ,以 28℃下的干扰系数最小 ,其模型为 A<
英文摘要:Influence of temperature and host plants on interference responses of Pediobius foveolatus Crawford was studied in the laboratory. The interference response of P. foveolatus to conspecific density was fitted very well to the modelA=
