油茶桃蛀螟生物学特性及灯光诱杀技术研究

Study on Biological Properties and Light Trap of ConogethespunctiferalisDamagingto Camellia oleifera Seeds

摘要: 调查了桃蛀螟Conogethespunctiferalis在丽水、衢州、金华地区危害油茶Camellia oleifera的情况，研究了其生物学特性，同时采用清除虫害果结合灯光诱杀进行了防治试验。结果表明，桃蛀螟对新造油茶林的危害低于老油茶林，桃蛀螟在丽水老油茶林内发生严重，油茶果危害率达31.27%；该虫在浙江地区1年4代，以老熟幼虫越冬，主要以第三代和越冬代幼虫危害油茶果；虫害果清理结合灯光诱杀对桃蛀螟有很好的控制效果，连续诱杀两年，危害率由28.78%降至10.72%。研究结果为油茶桃蛀螟的监测和防治提供了基础信息。

Abstract: In October 2016, investigations were carried out on damage ofConogethespunctiferalisto Camellia oleiferaseeds at stands in Quzhou, Lishui and Jinhua, Zhejiang province.Larvae of trapped C.punctiferaliswere feed at lab for observation of biological properties.In April 2017, sample plots were established for light trap.The results showed that C.punctiferalishad four generations a year, overwintered by mature larva in Zhejiang province.Itoccurred seriously in agedC.oleiferastands in Lishui, with damage rate of seeds of 31.27%.Larvae of the 3rd generation and overwintered generation damaged C.oleiferaseeds in filed.The experiments demonstrated that light trap had good control effect of C.punctiferalis.The damage rate dropped to 10.72% after two years experiment.
