内吸性杀虫剂被广泛用于密闭环境中如温室、仓库和室内,用于防治多种取食植物韧皮部的害虫,如蚜虫、粉虱、粉蚧和一些介壳昆虫。内吸性杀虫剂可用于喷雾,活性成分直接穿透植物组织(叶和茎),或被灌注及用作颗粒剂施于栽培基质上,经植物的根吸收,通过维管(韧皮部和木质部)系统分布到整个植物。昆虫在取食中摄入活性成分,当活性成分的量达到一定时昆虫死亡。
Internal systemic insecticides are widely used in closed environments such as greenhouses, warehouses and rooms for the control of pests such as aphids, whiteflies, mealybugs and some crustacean insects that feed on the phloem of plants. Suction insecticides can be used for spraying, the active ingredient penetrates directly into the plant tissues (leaves and stems), or is infused and used as a granule for application to the cultivation substrate, which is absorbed by the plant roots and is released through the vascular (phloem and xylem The system is distributed throughout the plant. Insects consume the active ingredient during feeding, and the insects die when the amount of active ingredient reaches a certain level.
