松褐天牛成虫羽化出孔规律研究

Adult Eclosion of Monochamus alternatus

对不同来源虫害木松褐天牛成虫羽化出孔特性进行对比研究 ,结果表明不同来源虫害木松褐天牛羽化出孔在时间动态上有一定差异 ,但其雌、雄成虫在各地种群中出孔动态基本相同。松褐天牛成虫出孔具有明显的时段性 ,高峰时段为 18:0 0～ 2 0 :0 0 ,占总数的 2 8% ,且雌、雄成虫同步。不同来源虫害木松褐天牛出孔率有一定差异 ,松材线虫病区虫害木中 。

Monochamus alternatus , a major vector of the fatal disease PWN, emerges from dead pine woods from late May through late July, with the peak number mainly in mid June depending on where the woods come from Both male and female adults come out from the wood most frequently at 18:00 pm 20:00 pm, contributing 28% to the total The ratio of eclosion and emergence varied among different locations, while the pine wood nematode, Bursaphelenchus xylophilus , negatively affects the ratio in the same wood source
