The botanical compound allyl isothiocyanate (AITC) is toxic to many microorganisms and insects. The aim of this study was to assess the effects of AITC on the Bradysia odoriphaga Yang et Zhang (Diptera: Sciaridae) and the seeds and seedlings of the Chinese chive. Allyl isothiocyanate was toxic to all four developmental stages of B. odoriphaga. The adult was significantly more sensitive to AITC than the other three stages, which exhibited no significant differences to one another in sensitivity to the chemical. The control efficacy of AITC against B. odoriphaga was far superior in the greenhouse than the field. In addition, seedling survival was higher in the greenhouse compared with that in the field. In the absence of B. odoriphaga, seed germination and seedling growth of Chinese chives were inhibited by 16 µl/liter of AITC, and significant inhibition occurred under higher doses of AITC. These results indicate that AITC could be used to control B. odoriphaga during cultivation of Chinese chives.
植物化合物异硫氰酸烯丙酯（AITC）对许多微生物和昆虫具有毒性。本研究的目的是评估AITC对韭菜迟眼蕈蚊（双翅目：眼蕈蚊科）以及韭菜种子和幼苗的影响。异硫氰酸烯丙酯对韭菜迟眼蕈蚊的所有四个发育阶段均具有毒性。成虫对AITC的敏感性明显高于其他三个阶段，而这三个阶段对该化学物质的敏感性彼此之间无显著差异。AITC在温室中对韭菜迟眼蕈蚊的防治效果远优于田间。此外，与田间相比，温室中的幼苗存活率更高。在没有韭菜迟眼蕈蚊的情况下，16微升/升的AITC会抑制韭菜种子发芽和幼苗生长，在更高剂量的AITC下会出现显著抑制。这些结果表明，AITC可用于韭菜种植过程中对韭菜迟眼蕈蚊的防治。
