【摘要】 本文研究 4种非嗜食植物乙醇提取物和机油乳剂在田间对柑桔潜叶蛾 Phyllocnistis citrella的产卵驱避效果 ,并用干扰作用控制指数 IIPC对这些效果进行评价。结果表明 ,处理后 2 4小时 ,0 .2 5 %机油乳剂和鸡矢藤、五爪金龙、樟树叶的提取物都有显著的产卵驱避作用 ,其中机油乳剂的驱避效果最好 ,IIPC为 0 .0 6 7,即产卵驱避效果为 93.3%,鸡矢藤、五爪金龙、樟树叶提取物也有较好的驱避效果 ,IIPC分别为 0 .0 96、0 .117、0 .15 6 ,即产卵驱避效果分别为 90 .4 %、88.3%、84 .4 %。只有番茄提取物没有显著的产卵驱避作用更多还原

【Abstract】 Alcohol extracts from 4 species of non preferable plants and a Petroleum Spray Oil,D C Tron NR were tested against citrus leafminer Phyllocnistis citrella in field. D C Tron NR and extracts from 3 plant species,Ipomoea hederacea,I. cairica and Cinnamomum camphora showed significant oviposition deterrence effect 24h after treatment. D C Tron NR gave the best result, with IIPC of 0.067. The IIPCs for extracts from I. hederacea,I. cairica and C. camphora were 0.096?0.117 and 0.156 respectively, with oviposition deterrent of 90.4%? 88.3% and 84.4% respectively. Alcohol extract from Lycopersicon esculentum didn’t show significant oviposition deterrence.更多还原
