不同糖源对象虫金小蜂寿命和繁殖能力的影响

为提高象虫金小蜂的室内扩繁效率,采用人工恒温饲养方法,分别选择葡萄糖、果糖、蔗糖、蜂蜜4种糖源,比较了糖源种类、浓度对象虫金小蜂寿命及繁殖能力的影响.结果表明:饲喂糖源可延长象虫金小蜂雌蜂和雄蜂的寿命,饲喂蜂蜜和果糖后象虫金小蜂雌、雄蜂寿命为对照的5.1～6.7倍,显著高于其他处理.随着糖源浓度的增加,象虫金小蜂雌蜂和...

Effects of different sugar sources on longevity and reproductive capacity of Anisopteromalus calandrae

In order to improve the indoor propagation efficiency of Anisopteromalus calandrae, the effects of types and concentrations of sugar sources on longevity and reproductive capacity of A. calandrae were studied by using glucose, fructose, sucrose and honey as sugar sources. The results showed that the longevity of female and male A. calandrae was significantly prolonged by feeding sugars. The longevity of female and male A. calandrae fed with honey and fructose was 5.1-6.7 times of the control, and was significantly longer than that under the other treatments. With the increase of sugar concentration, the longevity of female and male A. calandrae increased first and then decreased. The total number of adult wasps increased to 118.8-130.0, which was significantly higher than that of the control; however, there was no significant difference among different concentrations. When supplemented with 15% (volume fraction) honey water, the number of female progenies was the most (76.7), and the female to male ratio was the highest (2.9). Two sugar sources, honey and fructose, had the most influences on the longevity of A. calandrae, and the sugar concentration of 15% was the most beneficial for the improvement of reproductive efficiency of A. calandrae.
