| 摘 要： | 为了筛选在荔枝蝽若虫期对其具有良好防效的天敌昆虫，本试验探究蠋蝽对荔枝蝽1龄若虫的捕食潜力，在室内条件下评价了蠋蝽4龄若虫、5龄若虫、雌成虫和雄成虫对荔枝蝽1龄若虫的捕食能力，结合果园的观察总结了蠋蝽捕食行为特点。结果表明：蠋蝽4龄若虫、5龄若虫、雌成虫和雄成虫对荔枝蝽1龄若虫的捕食功能反应符合Holling Ⅱ模型，对荔枝蝽若虫的日最大捕食量分别为9.066、8.210、8.354和5.903头，瞬时攻击率分别为0.956、1.327、1.100和1.244，处理时间分别为0.10、0.162、0.132和0.149 d。不同龄期蠋蝽对荔枝蝽1龄若虫的搜寻效应均随猎物密度的增大而减小。室内外观察发现，蠋蝽捕食荔枝蝽若虫时的行为和捕食草地夜蛾等其他猎物时相似，经历搜索、跟随、攻击、取食、转移等行为反应。捕食功能试验证实蠋蝽对荔枝蝽1龄若虫具有较高的控害潜能，是实现荔枝蝽绿色防控的一种良好备选天敌产品。

| Abstract: | Predation of lychee stink bugs, Tessaratoma papillosa Drury, by Arma chinensis (Fallou) was evaluated with respect to functional responses the fourth instar nymphs, fifth instar nymphs, the female and male adults of A. chinensis to the first instar nymphs of T. papillosa. Logistic regression analysis revealed that the functional responses of A. chinensis to T. papillosa fitted well with type II. The maximum daily predation by the fourth instar nymph, the fifth instar nymph, female, and male of A. chinensis was 9.0, 8.2, 8.4 and 5.9, respectively; the corresponding attacking efficiency was 0.9562, 1.327, 1.100, and 1.244, respectively; and handling time was 0.105 d, 0.162 d, 0.132 d and 0.149 d, respectively. The search rate of A. chinensis on the first instar nymph of T. papillosa decreased with the increase in prey density. The predatory behaviors of A. chinensis, including searching, following, attacking, feeding, and movement were similar in predating nymphs of T. papillosa to other preys, such as armyworm. The results show that A. chinensis can achieve high control potential on the first instar nymph of T. papillosa and can serve as an effective bio-control agent against T. papillosa. |
