摘要: 目前柑桔潜叶蛾的防治主要依赖化学农药, 而且生产中缺少有效测报技术。为此, 我们于2009年6月30日至10月6日在浙江宁波通过有机合成柑桔潜叶蛾Phyllocnistis citrella(鳞翅目, 细蛾科)的3种性信息素化合物顺7, 顺11, 反13-十六碳三烯醛、顺7, 顺11-十六碳二烯醛和顺7-十六碳烯醛, 配制成不同浓度比例的混合物, 进行田间试验比较其引诱活性。结果表明, 单一的顺7, 顺11, 反13-十六碳三烯醛对柑桔潜叶蛾雄蛾就可以显示较强的引诱作用, 而顺7, 顺11-十六碳二烯醛单一成分没有引诱活性, 顺7, 顺11, 反13-十六碳三烯醛与顺7, 顺11-十六碳二烯醛的二元混合物30∶1~3∶1之间活性较强, 而在30∶1的质量比例时诱虫量最高。含顺7-十六碳烯醛的三元混合物, 当顺7, 顺11, 反13-十六碳三烯醛∶顺7, 顺11-十六碳二烯醛∶顺7-十六碳烯醛三者比例为100∶10∶3时有显著增效作用。剂量与诱捕活性试验显示每枚诱芯1 mg顺7, 顺11, 反13-十六碳三烯醛的剂量引诱作用最强, 随浓度降低, 引诱作用下降。诱捕器在0.8~1.5 m之间的不同悬挂高度对诱捕数量无显著影响。结果说明, 顺7, 顺11, 反13-十六碳三烯醛、顺7, 顺11-十六碳二烯醛和顺7-十六碳烯醛组成的三元混合物诱芯可以作为柑桔潜叶蛾的诱杀技术并应用于其生物防治和预测测报。

Abstract: The prevention and control of the citrus leafminers Phyllocnistis citrella (Lepidoptera: Gracillariidae) currently relies on chemical pesticides, and shows a lack of effective forecasting techniques. Sex pheromone components Z7,Z11,E13hexadecatrienal (Z7,Z11,E13-16Ald), Z7,Z11-Hexadecadienal (Z7,Z11-16Ald) and Z7-hexadecenal (Z7-16Ald) from P. citrella were synthesized and tested for their attractiveness to male moths in citrus orchards in Ningbo, Zhejiang, China during the period of June 30 to October 6, 2009. The results showed that Z7,Z11,E13-16Ald attracted male moths strongly, but neither Z7,Z11-16Ald nor Z7-16Ald trapped a significant number of male moths. The optimal ratio of binary blends of Z7,Z11,E13-16Ald and Z7,Z11-16Ald was between 30∶1 and 3∶1, and the binary blends at the ratio of 30∶1 trapped the highest number of males. The highest dosage for catching males was 1 mg pheromone blend formulated with the mixture of Z7,Z11,E13-16Ald and Z7,Z11-16Ald at the ratio of 3∶1. The trinary blends (Z7,Z11,E13-16Ald∶Z7,Z1116Ald∶Z7-16Ald=100∶10∶3) showed significant synergistic effects. The height of pheromone trap between 0.8 and 1.5 m had no significant effect on trapping efficiency. These results indicate that the synthetic pheromone lures can be used as the trap strategy of citrus leafminers and applied in pest control and forecasting in the field.

Key words: Phyllocnistis citrella, sex pheromone, pheromone trap, Z7,Z11,E13-hexadecatrienal, Z7,Z11-hexadecadienal, Z7-hexadecenal
