| 摘 要： | 木麻黄皮暗斑螟（ＥｕｚｏｐｈｅｒａｂａｔａｎｇｅｎｓｉｓＣａｒａｄｊａ）在福建省一年发生５代，以幼虫于１２月中旬在树干被害处的虫道内越冬（亦有少数以蛹越冬），林间世代重叠现象明显。成虫羽化盛期的温度为３０．３—３４．０℃，相对湿度为７５．７％—８４．３％，平均寿命７．９天，产卵量４５．７粒。卵孵化率９０．５％。幼虫共５龄，具群集性，以第一代幼虫取食量最大，老熟幼虫喜在粪粒层与树干交界部结茧化蛹，蛹期８．５天。皮暗斑螟的天敌有１０余种，其中拟小腹茧蜂在自然界的寄生率达１６％。

| Abstract: | Euzophera batangensis had 5
generations per year in Fujian Province and the overlap phenomenonof generations was
evident in the forests.This paper detailedly studied the biological characteristics of
thelarvae.adults and pupae of E.batangensis.There were over ten species of natural enemies
for E.batangen- sis,among which the parasitical rate of P seudapantelessp.reached 16%in the
nature. |
