摘要: 井上蛀果斑螟是云南石榴上的一种主要蛀果害虫.为明确石榴不同品种对该虫生长发育和繁殖的影响,在温度(25±1) ℃、光周期15 L∶9 D、相对湿度(70±10)%条件下,系统观察了井上蛀果斑螟在甜绿籽、厚皮甜沙籽、甜光颜、酸绿籽和酸沙籽5个品种上的发育历期、存活率和产卵量等生物学特性,并组建了其实验种群生命表.结果表明: 井上蛀果斑螟在5个石榴品种上的卵期、幼虫期、蛹期、雄成虫寿命、全世代历期及卵孵化率均无显著差异;预蛹期、雌成虫寿命、幼虫存活率、化蛹率、羽化率、总成活率、单雌产卵量及雌雄蛹质量存在显著差异,除幼虫存活率外,均以酸绿籽种群较高,厚皮甜沙籽种群次之,二者间差异不显著.生命表参数表明,净增殖率、内禀增长率和周限增长率均为酸绿籽种群显著高于甜绿籽、甜光颜和酸沙籽种群,但与厚皮甜沙籽种群差异不显著;平均世代周期各品种间无显著差异;种群加倍时间为酸绿籽种群显著小于其余4个品种.5个石榴品种中,酸绿籽和厚皮甜沙籽较适宜井上蛀果斑螟的生长发育和繁殖.

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.
