入侵性害蟲會嚴重干擾當?shù)乩ハx群落,對農(nóng)業(yè)和森林造成相當大的破壞。在這些害蟲中,粉虱（半翅目Hemiptera:粉虱科Aleyrodidae）和小菜蛾（Plutella xylostella L.）（鱗翅目Lepidoptera:小菜蛾科Plutellidae）是對包括中國在內(nèi)的全球農(nóng)作物危害最為嚴重的害蟲類群。小花蝽屬（Orius）是雜食性捕食昆蟲,捕食范圍廣。在這些種類中,南方小花蝽（Orius strigicollis Poppius）（半翅目Hemiptera:花蝽科Anthocoridae）正是我國農(nóng)田常見而有效的天敵,被用作經(jīng)濟作物害蟲防控的重要生防因子。捕食者捕食特定獵物后的發(fā)育、繁殖及其適應(yīng)能力,突出了其作為一種有效生物控制因子的潛力。獵物的類型和溫度波動會顯著影響捕食者的生物學(xué)和生命表參數(shù)。在本研究中,作者評估了在不同溫度下,食料種類的不同對南方小花蝽在捕食行為和生命表特征上的波動效應(yīng)。同時,采用蟲齡-蟲態(tài)、兩性生命表技術(shù),對南方小花蝽作為生物防治因子的性能進行了評價。主要研究結(jié)果如下:一、飼喂不同密度的兩種粉虱條件下南方小花蝽的捕食功能反應(yīng)研究在實驗室條件下,研究了南...
