不同石榴品种对井上蛀果斑螟生长发育和繁殖的影响
Effects of pomegranate varieties on the development and fecundity of Assara inouei Yamanaka (Lepidoptera : Pyralidae)
摘要
Abstract
Assara inouei Yanmanaka is an important pest of pomegranate fruits in Yunnan Province.To examine the effects of different pomegranate varieties on the development and reproduction of A.inouei,the biological characteristics,such as the developmental duration,the survival rate and reproduction of this pest feeding on five pomegranate varieties including Tianlvzi,Houpitianshazi,Tianguangyan,Suanlvzi and Suanshazi were observed respectively,and the life table parameters were established under the laboratory conditions of (25±1) ℃,RH (70±10)％ and a photoperiod of 15 L:9 D.The results showed that there were no significant differences in the egg stage,larval stage,pupal stage,the longevity of male adults,generation duration form egg to adult and egg hatch rate among the five varieties.There were significant differences in the pre-pupal stage,the longevity of female adults,larval survival,pupation,eclosion and total survival rates,the number of eggs laid per female as well as male and female pupal mass among the five varieties,and all of which except the larval survival were higher on Suanlvzi,followed by Houpitianshazi,but there was no significant difference between these two varieties.The results of life table showed the net reproduction rate,the intrinsic rate of increase and finite rate of increase of the Suanlvzi population were the highest.There were no significant differences in the mean generation time among the five varieties,but significant difference was observed in the population doubling time,which was the shortest on Suanlvzi population.The development and reproduction of A.inouei were better on the Suanlvzi and Houpitianshazi among the five varieties.关键词
