摘要
鞭角华扁叶蜂是柏木、柳杉的一种毁灭性害虫,自1987年在仙居萍溪林场发现小面积柏木受害后,至1989年迅速扩展到164ha。本文在摸索鞭角华扁叶蜂生物学特性、防治方法的基础上,根据害虫发生规律,利用物候、农事及根据蛹化率、孵化率分别与日期回归方程所确定的期距法进行害虫发生期的预测预报;参照其它森林害虫繁殖量计算方法,并根据上年老熟幼虫虫口密度基数进行幼虫发生量预测预报。为防治鞭角华扁叶蜂为害提供依据。
Chinolyda flagellicornis is a devastating insect pest of Cupressus funebris Endl.
and Cryptomeria fortunei Hooibrenk. From 1987, after finding disaster of Cupressus funebris
Endl.of small area at Pingxi forest farm, till 1989 it has rapidly spread to 164 ha. On the basis of
groping for biological characteristics and control method of Chinolyda flagellicornis, according
to happening regular of insect pest to forecast happening period of insect pest with phenoiogy
and farming, refering to calculative method of breeding quantity of insect pest in other forest
and according to population density base of old maturi larva last year to forecast happening
quantity of larve. It provides basis for control harm of Chinolyda flagellicornis.
