摘要: 为明确东亚小花蝽的饥饿耐受能力以及不同程度饥饿对其繁殖和捕食能力的影响,通过室内模拟饥饿胁迫环境,测定了长期饥饿环境下不同发育阶段东亚小花蝽的存活率和寿命,并分析了不同程度短期饥饿对其雌成虫产卵量、卵孵化率、捕食量和捕食效能的影响。结果表明,东亚小花蝽雌成虫的耐饥饿能力最强,平均寿命为14.15 d,显著高于雄成虫和若虫。不同程度短期饥饿对东亚小花蝽雌成虫繁殖力影响不同,当饥饿时间达到72 h后,其产卵率和产卵量明显下降,分别为78.33%和82.47粒,显著低于对照(无饥饿处理的雌成虫,96.67%和110.20粒)。对照和各饥饿处理组东亚小花蝽对棉铃虫卵的捕食功能反应均符合Holling Ⅱ模型,但模型的各项参数均发生了变化,当饥饿时间分别为24 h和48 h时,其捕食效能(分别为38.384 1和32.026 9)与寻找效应最低值(分别为0.707 0和0.680 5)均高于对照(28.372 0和0.643 8);当饥饿时间达到72 h后,其捕食效能与寻找效应最低值(分别为19.070 9和0.592 5)均显著低于对照。综上,应优先选择东亚小花蝽雌成虫作为田间释放应用的最佳虫态,但运输、储存时饥饿时间超过72 h会显著降低雌成虫的繁殖和捕食能力,影响其在田间的定殖和控害效果。

Abstract: In order to clarify the starvation tolerance of Orius sauteri and its fecundity and predation capacity under different extents of starvation,this study simulated a starvation stress environment indoors.The survival rate and lifespan of O.sauteri at different developmental stages were measured under long‑term starvation conditions,and the effects on longevity,egg number,egg hatch rate,predation amount,predation function response and searching efficiency of female adults under various levels of starvation were analyzed.The results showed that female adults of O.sauteri possessed the highest starvation tolerance,with an average lifespan of 14.15 days,significantly longer than that of male adults and nymphs.There was a significant difference in the fecundity of female adults of O.sauteri under varying durations of starvation.Both the oviposition rate and egg number of females starved for 72 hours declined significantly(78.33% and 82.47 eggs,respectively)in relative to the control(females adults without starvation treatment,96.67% and 110.20 eggs,respectively).Under the control and three starvation treatments,predation of female adults of O.sauteri on Heliothis assulta eggs still conformed to Holling Ⅱ functional response models,though with modifications to their parameters.The predation efficiency(38.384 1 and 32.026 9,respectively)and the lowest value of search effect(0.707 0 and 0.680 5,respectively)of female adults starved for 24 and 48 hours were both significantly higher than those of the control(28.372 0 and 0.643 8).However,the predation efficiency(19.070 9)and minimum search effect(0.592 5) of females starved for 72 hours were lower than those of the control.Our results indicated that O.sauteri females should be prioritized as the optimal biological agent for field applications.However,starvation duration exceeding 72 hours significantly reduced the reproductive and predatory capacities of female adults,negatively impacting their field colonization and pest control efficacy.
