摘要
档案窃蠹Falsogastrallus sautevi Pic每年发生一代。在22～30℃和相对湿度60%以上时,卵孵化率与温、湿度呈显著正相关。在20℃和相对湿度50%以下时,极不利于卵的发育。卵、幼虫和蛹的平均历期和成虫寿命的长短,均与其适合范围内的温度变化呈显著或极显著对数曲线负相关。卵、幼虫、蛹的死亡率分别为24.6%、88.1%和10.07%。雌、雄成虫寿命各为38.33±10.47及34.18±10.14天。成虫产卵前期为20.95±4.02天。平均每雌每次产卵7.6±0.6粒,每雌产卵14.7±3.6粒。雌性比率与温度呈极显著幂函数曲线负相关。
Falsogastrallus sauteri Pic usually produces one generation a year. The hatching percentage of eggs is positively correlated with the change of temperature within 22-30℃ and RH above 60%, Temperature lower than 20℃ and RH lower than 50% are unfavorable to the development of eggs. The mean development period of eggs, larvae, pupa and the longevity of adult are negatcively correlated with temperature and he correlation coefficients were sinificant or highly significant. Mor(?)lity of eggs, larvae, pupa is 24.60%, 88.1% and 10.07% respectively. The longevity of females and males is observed to be 38.32±10.47 and 34.18±10.14 days. The oviposition period is 20.95±4.02 days. On an average, a female adult can lay 14.70±3.6 eggs, 7.6±0.6 eggs are deposited each time. The percentage of the female in the population is ngatively correlated with temperature chaneg, too. The crrelaltion coefficient is highly significant.
