林口红松球果害虫幼虫鉴定及发生时序

Larva Identification of Cone Pests and Damaging Timeline from Pinus koraiensis in Linkou,China

2020年6月6日、7月10日、8月10日、9月15日,在黑龙江省七台河市林口县通天一林场40~50年红松(Pinus koraiensis)林内,采集2年生红松球果受害球果内的幼虫,利用幼虫形态特征并结合线粒体COⅠ基因对比进行幼虫种类鉴定。共鉴定出5种球果害虫:油松球果小卷蛾(Gravitarmata margarotana)、冷杉梢斑螟(Dioryctria abietella)、赤松梢斑螟(D.sylvestrella)、小卷蛾未知种(Cydia sp.)、小花尺蛾(Eupithecia abietaria debrunneata);详细描述了5种球果害虫幼虫形态特征及在红松球果内的发生时序。

The larvae from damaged Pinus koraiensis biennial cones in forest farm Tongtianyi(Linkou, Heilongjiang province) were collected on 6 June, 10 July, 10 August, and 15 September, and were identified by morphology and COⅠ gene. There are five pests in the cones: Gravitarmata margarotana, Dioryctria abietella, D. sylvestrella, Cydia sp., and Eupithecia abietaria debrunneata. The larval morphology and damaging timeline of the five pests were detailed described.
