华山松木蠹象Pissodes punctatus是松类树种的重要蛀干害虫。本文通过对华山松木蠹象连续4年的饲养,总结出了采用松木段和人工蛹室的简便实用饲养方法,可以实现华山松木蠹象的连续传代饲养,建立了华山松木蠹象实验种群,并观察其隐蔽阶段的生活习性。饲养结果表明:华山松木蠹象在昆明1年2代,完成1个世代的平均历期为104.5 d,其中卵期8~20 d,幼虫期45-88 d,蛹期20~28 d,世代不整齐,没有明显的越冬期。成虫寿命很长,平均可成活377 d,且全年可以持续交尾和产卵,每头雌成虫一生平均产卵105.5粒
Pinus armandi Pissodes punctatus is an important borer pest of pine species. This paper summarizes the simple and practical feeding method of pine wood pipit and the artificial pupation room by feeding the Picea pungens for four years in succession, which can achieve the continuous subculture of Pinus armandii and establish the experimental population Observe the hidden habits of life. The breeding results showed that the average age of Picea asperata in Kunming was 1 year and 2 generations, and the average duration of one generation was 104.5 days, of which 8-20 days were in egg stage, 45-88 days in larva stage, 20-28 days in pupal stage, Unregular, no obvious wintering. Adult life is very long, the average survival of 377 d, and throughout the year can continue to cross and spawn, each female average life spawning 105.5
