Abstract

Data characterizing the gypsy moth Lymantria dispar population in the eruptive phase in the Far East territory in 2008 are presented. The death of insects based on biotic factors (parasitoids and nuclear polyhedrosis virus) has been studied; the sex ratio, weights of male and female pupae, and female fecundity have been determined. It is shown that nucleopolyhedrovirus is the main cause of death for caterpillars and inhibits the eruptive phase of abundance. It appears that no gypsy moth caterpillars die from entomopathogenic fungi. A strong decrease in the proportion of females is partially mediated by sex-specific parasitism and the moderate fecundity of females, and a high rate of virus-induced mortality is responsible for the fast decline in L. dispar population density in the Far East.

远东吉普赛蛾（Lymantria dispar L.）人口暴发的特征

摘要

数据表征舞毒蛾舞毒蛾在2008年的远东领土的喷发阶段人口呈现。已经研究了基于生物因子（寄生虫和核多角体病毒）的昆虫的死亡；确定了性别比，雌雄weight的体重和雌性繁殖力。结果表明，核多角体病毒是毛毛虫死亡的主要原因，并抑制了丰富的爆发期。看来没有吉普赛蛾毛虫死于昆虫病原真菌。雌性比例的强烈下降部分是由性别特异性寄生虫和雌性中度繁殖力引起的，病毒引起的死亡率高是造成L. dispar迅速下降的原因。 远东的人口密度。
