| 摘 要： | 为选择蠋蝽Arma chinensis(Fallou)早期释放的最佳阶段,预测蠋蝽释放后的存活率,本研究在人工气候箱内,不提供食物,只提供水的情况下比较了不同龄期蠋蝽耐饥能力,探究了不同饥饿处理时间对蠋蝽成虫取食能力以及雌虫繁殖能力的影响。结果表明,饥饿状态下,蠋蝽各龄期存活时间存在极显著差异,其中雌成虫耐饥能力最强,平均存活时间为28.74 d;1~5龄若虫以及雄成虫的平均存活时间分别为7.43、6.59、10.04、13.39、17.96和20.29 d。饥饿处理后,蠋蝽雌、雄成虫取食黏虫2龄幼虫量(雌3.0头、雄2.9头)较对照(雌0.5头、雄0.7头)显著提高。此外,同一时间的饥饿处理,雌、雄成虫之间取食量没有显著差异。饥饿处理3、6和9 d后蠋蝽产卵总量(117.0、162.3和140.0粒)较对照(181.8粒)下降,但未达到显著差异;饥饿处理3、6 d后卵孵化率(64.45%、68.10%)较对照(78.03%)显著下降,而饥饿9 d处理较对照孵化率(77.85%)虽然降低,但未达到显著差异。本文研究结果表明,蠋蝽成虫耐饥能力最强,且短时间饥饿对其繁殖力未产生显著影响,是田间早期释放的最佳虫态。

| 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. |
