习水县蚜虫发生情况及放蜂后蚜虫变化调查

The Investigation of Aphids Occurrence and Put Queen Change in Xishui County

通过调研蚜虫的发生情况以及蚜茧蜂放飞后蚜虫密度变化情况,可以为科学防治蚜虫提供理论依据。以习水县为调研地点,选择烟草、白菜、萝卜、油菜等作物,调查了蚜虫的发生情况与蚜茧蜂防治效果。结果表明,烟草蚜虫发生情况重于其他作物,其中,烟草无翅蚜发生情况最重,而其他作物是有翅蚜发生最重;从蚜茧蜂防治效果来看,在蚜虫发生不严重时,具有较好的防治效果;当蚜虫发生较重时,防治效果欠佳。

The research of aphid occurrence and the change of the density of aphid cocoon bees fly after aphids, can provide theoretical basis for scientific prevention and control of aphids. In xishui county as the research site, selection the tobacco, Chinese cabbage, radish, rape and other crops, the paper examines the occurrence of aphids and aphid cocoon bees control effect. The results showed that tobacco aphid was more important than other crops, tobacco wingless aphid occurrence was the heaviest, other crops winged aphid was the heaviest; from the point of aphid cocoon bees control effect, not serious in aphids has good control effect, when aphids occurred heavier, control effect was limited.
