摘要
室内条件下饲养狭翅大刀螳 (Tenoderaangustipennis) ,研究温度与光照两个因子对狭翅大刀螳生长发育的影响 ,同时考察狭翅大刀螳若虫对不同密度小菜蛾幼虫与成虫及萝卜蚜的捕食功能反应 .结果表明 ,温度对狭翅大刀螳生长发育的影响显著 ,随着温度的升高 ,在设定的温度范围内其历期明显缩短 .狭翅大刀螳 1～ 3龄若虫最适生长温度为 2 5℃ ,而 4、5龄若虫的最适生长温度为 2 5～ 30℃ .单因子光照对狭翅大刀螳生长发育无显著影响 .捕食功能反应试验所得的数据 ,按Holling模型进行模拟 ,经卡方检验 ,其理论值与实测值无显著差异 ,证明建立的模型能较好地模拟狭翅大刀螳的捕食情况 .
Tenodera angustipennis was raised under laboratory conditions to study the influence of temperature and light on the growth and development of its nymphs.The functional responses of T.angustipennis to Plutella xylostella (L.) larvae and adults and to Lipaphis erysimi (Kaltenbach) were also studied.The results showed that temperature remarkably affected the growth and development of T.angustipennis,but light did not.The Holling models could well describe the functional responses of T.angustipennis to P.xylostella and L.erysimi.
