Abstract

The toxicity of different doses (3, 4, 5, 6 and 7 percent) of Acorus calamus essential oil, against insect pest Sitophilus oryzae were evaluated in the laboratory of Division of Entomology, FoA, Wadura, SKUAST-Kashmir during the year 2022. The various concentrations of Acorus calamus essential oil had significant effect on mortality of Sitophilus Oryzae. The highest mortality of 74.27 percent was recorded in 70 µl concentration of Acorus calamus essential oil on 12 Hours After Treatment (HAT) followed by 60 (71.01%), 50 (67.15%) and 40 (39.11%) µl concentration while untreated control recorded 5.13 percent mortality respectively. However, on 24 HAT the cumulative mortality increased to 76.35 in 70µl, 74.11 in 60 and 50 µl, 43.01 in 40 µl concentration. On 72 HAT the concentrations of 70, 60 and 50 µl recorded 94.11, 91.27 and 90.11 percent mortality respectively, while only 7.05 percent mortality was recorded in untreated control.

不同剂量的石菖蒲精油对镰刀菌的杀虫活性

2022 年，在克什米尔 SKUAST 瓦杜拉 FoA 昆虫学分部的实验室里，对不同剂量（3%、4%、5%、6% 和 7%）的石菖蒲精油对害虫嗜坐螨的毒性进行了评估。不同浓度的石菖蒲精油对稻田害虫的死亡率有显著影响。在处理后 12 小时（HAT），70 µl 浓度的石菖蒲精油的死亡率最高，达到 74.27%，其次是 60 µl 浓度（71.01%）、50 µl 浓度（67.15%）和 40 µl 浓度（39.11%），而未经处理的对照组死亡率仅为 5.13%。然而，在 24 小时孵化期，70 微升浓度的累积死亡率增至 76.35%，60 和 50 微升浓度的累积死亡率增至 74.11%，40 微升浓度的累积死亡率增至 43.01%。在 72 小时孵化期，70、60 和 50 微升的浓度分别记录了 94.11%、91.27% 和 90.11%的死亡率，而未经处理的对照组仅记录了 7.05%的死亡率。
