EXPERIMENTS ON THE USE OF ESSENTIAL OILS AGAINST STORED-PRODUCT INSECTS IN STOREHOUSE

摘要: 采用4种精油对4种仓库害虫进行了模拟实仓防治试验.结果发现,0.2％(W/W)肉桂油拌种对小麦的保护效果可维持8个月以上.以0.45mg/cm~2的剂量处理麻袋,齿叶黄皮和八角茴香精油处理能保持小麦4个月无虫,肉桂油可保持8个月无虫.实仓试验中发现,15ppm马拉硫磷加15ppm肉桂油混用处理.虫口减退率达100％.30ppm马拉硫磷和30ppm肉桂油处理的虫口减退率分别为89.8％和98.5％.

Abstract: The tests of four essential oils against 4 species of storedproduct insects, Sitophilus zeamais, Tribolium casta-neum, Oryzuephilus surinamensis and Rhizopertha dominica,insimulated storehouse were carried out in Guangdong Province. The results showed that cassia oil at a dosage of 0. 2% by seed dressing kept the stored wheat free from damage by insects for as long as 8 months. Using a dosage of 0. 45 mg/cm2 to treat gunnysack, the essential oils from Illici-um verum and Clausena dunniana protected the wheat from being damaged by stored-product insects for 4 months, whereas cassia oil for as long as 8 months. The results of experiments in storehouse indicated that the combination of 15 ppm cassia oil caused 100% mortality of stored-product insects and 30 ppm malathion or 30 ppm cassia oil caused tested insects 89. 5% and 98. 5% mortalities, respectively.
