短期饥饿处理对蠋蝽寿命、繁殖力及捕食量的影响
Effects of Short Term Starvation on Longevity, Fecundity and Predation of Arma chinensis (Hemiptera: Pentatomidae)
摘要
Abstract
In order to choose an optimal release stage and predict the survival rate after release,we examined the effects of starvation on longevity,fecundity and predatory capacity of adult Arma chinensis (Fallou) under laboratory conditions.The results showed that there was significant difference in survival time among different developmental stages under starvation,the tested female adults lived longer (28.74 d) than the other stages (1-5 instar larvae and male adults,at 7.43,6.59,10.04,13.39,17.96 and 20.29 d,respectively).The starved A.chinensis adults consumed significantly more 2nd instar larvae of Mythimna separate (Walker) (3.0 and 2.9 preys for female and male adults,respectively) than the un-starved control (0.5 and 0.7 preys for female and male adults,respectively).However,no difference in predation was found among different states of starvation or between male and female adults.The fecundity of the females starved for 3,6 and 9 days declined (117.0,162.3 and 140.0 eggs,respectively) in relative to the control (181.8 eggs),but the differences were not significant.Egg hatchability of both 3-day-starved (64.45%) and 6-day-starved (68.10%) A.chinensis were significantly lower than that of the control (78.03%) and the 9-day-starved (77.85%) ones.The results of this paper indicate that the adults ofA.chinensis have the strongest starvation tolerance,short term starvation does not significantly decrease the fecundity ofA.chinensis,but increases their predation.Thus,adults ofA.chinensis can be the optimal stage to be used in the early field release.关键词
