【摘要】 为探究外源营养对圆柏大痣小蜂Megastigmus sabinae Xu et He成虫寿命的影响，本研究通过给当日羽化的同批次圆柏大痣小蜂成虫饲喂清水、蔗糖水及蜂蜜水，研究不同外源营养饲喂对雌、雄成虫寿命的影响。研究表明：3种喂养条件下雄蜂寿命均短于雌蜂，其中清水饲喂雌、雄蜂寿命差异显著；取食蔗糖水和蜂蜜水的圆柏大痣小蜂雌蜂寿命分别为18 d和14 d，两者均与饲喂清水对照之间存在显著差异；雌、雄蜂单独饲喂与雌、雄蜂混合饲喂存活数变化趋势基本一致。本研究为圆柏大痣小蜂生物防治研究提供虫源保障，同时也为研究圆柏大痣小蜂的生物学特点和行为提供支持。更多还原

【Abstract】 The effect of supplementary food on the longevity of female and male adults of Megastigmus Sabinae was investigated by feeding the wasps with water, sucrose solution and honey solution. The results showed that the males lived shorter than the females under the three feeding treatments, and the longevity of females and males fed with water differed significantly. The females fed with sucrose solution and honey solution lived 18 days and 14 days, both significantly different from that of the wasps fed with water. The survival of the wasps showed no difference between the wasps individually reared and group reared. The results are of help for the mass rearing of M. sabinae and for future study of the biological characteristics and behavior of M. sabinae.更多还原
