The application of azadirachtin to foliage of cantaloupes did not significantly reduce successful pollination by commercially managed honey bees, Apis mellifera L., as measured by numbers of foraging honey bees and yield. Similar results were obtained when the synthetic insecticide imidacloprid (used as a standard by cantaloupe growers) was applied to the soil. Fruit yield and quality, as a function of bee pollination, were statistically equal between the two treatments, and equal to that of the untreated control. The standard treatment of imidacloprid gave significantly better control than azadirachtin of one pest (cucumber beetle) early in the season. Fruit maturity was delayed in untreated plots, consistent with light insect pressure observed. These results indicate that an organically based insect control approach will not alter bloom acceptance and bee forager activity in cantaloupes.
通过商业管理的意大利蜜蜂(Apis mellifera L.)对哈密瓜进行授粉,以觅食蜜蜂数量和产量衡量,印楝素施用于哈密瓜叶片上并未显著降低成功授粉率。当将合成杀虫剂吡虫啉(哈密瓜种植者用作标准)施用于土壤时,也获得了类似结果。作为蜜蜂授粉的函数,两种处理之间的果实产量和品质在统计学上相等,且与未处理对照相等。在季节早期,吡虫啉的标准处理对一种害虫(黄瓜甲虫)的防治效果明显优于印楝素。未处理地块的果实成熟延迟,这与观察到的轻微虫害压力一致。这些结果表明,基于有机的昆虫控制方法不会改变哈密瓜的花朵接受度和蜜蜂觅食活动。
