许多作物依靠昆虫传粉,传粉的主要媒介是蜜蜂。如果在这些作物上使用杀虫剂,把害虫和传粉昆虫同时杀死,其实用价值就很成问题。不过,只要不在蜜蜂大量活动的开花期施药,对蜜蜂的大部份危害仍是可以避免的,若在夜晚施药就更为安全了。其他措施还有:(1)仅在需要时施药;(12)以最低的有效剂量和施用最少的次数;(3)如果不得不在蜜蜂活动的时候施药,则应采用对蜜蜂危害最轻而对目标害虫有效的药剂;(4)尽量使用颗粒剂或低浓
Many crops depend on insects for pollination, and the main medium for pollination is bees. The practical value of using pesticides on these crops to kill pests and pollinators at the same time is problematic. However, most of the damage to bees can be avoided as long as they are not applied at the flowering stage of large bee activities, and it is even safer to administer them at night. Other measures include: (1) spraying only when needed; (12) with the lowest effective dose and the least number of applications; (3) the least harmful to bees if they have to be applied while bees are active While the target pest effective agents; (4) try to use granules or low concentration
