[目的]研究新疆喀什设施蔬菜种植区人工繁殖丽蚜小蜂的扩散功能,为利用人工繁殖丽蚜小蜂防治温室白粉虱提供技术支持。[方法]试验设置三个重复处理,放蜂数量均为2 000头,放蜂点设在温室大棚的中部,以放蜂点为中心点,对距离中心点东西方向2、4、6、8 m处植株作插牌标记,放蜂后3 d,采集标记植株叶片,带回室内观察寄生率,分析扩散距离与寄生率之间的关系。[结果]丽蚜小蜂释放后第3 d,寄生率由中心点向东西两侧呈降低趋势,放蜂中心点和距中心点2 m处被丽蚜小蜂所寄生的白粉虱若虫寄生率之间没有显著差异,分别为中心点83.94%、2 m处为80.79%和77.36%,而与距中心点4、6和8 m处存在显著或极显著差异。距中心点8 m处平均寄生率最低,为11.46%和3.17%。[结论]在温室条件下,人工繁殖丽蚜小蜂由放蜂中心点向两侧扩散距离越远,寄生率越低。放蜂后3 d丽蚜小蜂的扩散范围集中在半径2 m的范围内,有部分个体扩散距离可以达到4～6 m,有极少数个体扩散距离可以达到8m。
[Objective] The study aimed to study the dispersal function of Artemia aphididae propagated in vegetable planting areas in Kashgar, Xinjiang, and to provide technical support for the control of B. tabaci by artificial propagation of Aphididae. [Method] The experiment was set up with three repeated treatments. The number of bee-pollination was 2 000. The bee-keeping point was set in the middle of the greenhouse and the bee point was taken as the central point. The distance from the center to the east-west direction was 2, The plants were inserted into the m mark for 3 days after the bee-eater, and the leaf marks of the plants were collected to observe the parasitism rate. The relationship between the spread distance and the parasitism rate was analyzed. [Result] The parasitism rate decreased from the central point to the east and the west of the 3rd instar larvae on the 3rd day after the release of the larvae. The parasitism rate of the parasite of the whitefly parasitoids parasitized by the larvae at 2 m away from the central point Were 83.94% at the center, 80.79% and 77.36% at 2 m, respectively, but not significantly different from 4, 6 and 8 m from the center. The average parasitism rate was the lowest at 8 m from the center, which was 11.46% and 3.17% respectively. [Conclusion] Under the condition of greenhouse, the parasitism rate was lower with the spread of Artemia aphid from the center of amphibian to the both sides. The dispersal range of the queen aphid was concentrated within a radius of 2 m 3 d after beekeeping, with some individuals reaching 4 to 6 m, and a very small number of individuals spreading to 8 m.
