Abstract This study aimed at evaluating the toxicity of allyl isothiocyanate (AITC) to adults of Callosobruchus maculatus (Fabricius) (Coleoptera: Chrysomelidae) and its effects upon oviposition rate, population development, respiration rate, and dry mass loss in cowpea beans. The toxicity of AITC was determined by applying lethal concentrations (LC) of the compound, whereas the mortality curves were drawn by utilizing increasing concentrations of AITC (from 5.0 to 13.33 mL m−3 of grains). Population development was assessed through oviposition, progeny and both daily and accumulated emergence at sublethal concentrations (LC1 = 3.81 mL m−3, LC 10 = 5.71 mL m−3, LC 30 = 7.67 mL m−3, and LC 50 = 9.41 mL m−3). Furthermore, the loss of dry mass in grains and the respiration rate of adults when exposed to AITC (LC1, LC10, LC30, and LC50) were withal appraised. The values of LC 50 and LC 95 to adults of C. maculatus were of 9.41 and 17.85 mL m−3 of grains, respectively. At sublethal concentrations of AITC, the respiration oviposition, and emergence rates declined. The fumigant agent also prevented mass loss in cowpea beans. On account of that, it is safe to say that the compound has significant potential for controlling C. maculatus, inhibiting its development in storage conditions.

异硫氰酸烯丙酯对黄斑蝾螈的毒理和生理作用

摘要 本研究旨在评估异硫氰酸烯丙酯 (AITC) 对豇豆（Fabricius）（鞘翅目：Chrysomelidae）成虫的毒性及其对豇豆的产卵率、种群发展、呼吸率和干物质损失的影响。AITC 的毒性是通过应用该化合物的致死浓度 (LC) 来确定的，而死亡率曲线是通过使用逐渐增加的 AITC 浓度（从 5.0 到 13.33 mL m-3 的谷物）绘制的。通过产卵、后代以及亚致死浓度（LC1 = 3.81 mL m-3，LC 10 = 5.71 mL m-3，LC 30 = 7.67 mL m-3，LC 50 = 9.41 mL）评估种群发育米-3）。此外，暴露于 AITC（LC1、LC10、LC30、和 LC50) 进行了评估。C. maculatus 成虫的 LC 50 和 LC 95 值分别为 9.41 和 17.85 mL m-3 谷物。在亚致死浓度的 AITC 下，呼吸产卵和出现率下降。熏蒸剂还可以防止豇豆的质量损失。有鉴于此，可以肯定地说，该化合物具有控制黄斑念珠菌的巨大潜力，可抑制其在储存条件下的发育。
