黑胸散白蚁分离饲养补充型生殖蚁的产生及羽化分飞行为

The production of substitute reproductives and eclosion-swarming behavior in segregated,captive colonies of Reticulitermes chinensis

对黑胸散白蚁Reticulitermes chinensis Snyder成熟群体进行室内自然条件分离饲养观察,结果表明:单品级分离群体和多品级分离群体均能产生补充型生殖蚁,产生补充型生殖蚁的概率与分离群体内的个体数量呈正相关关系,分离时间和气温对产生补充型生殖蚁的历期影响较大,1、4、6、9月分离的群体产生补充型生殖蚁的历期分别为78.50、46.00、32.17、26.00d,经分析差异显著(P<0.05)。分离群体能迅速产出有翅成虫羽化分飞,在分离后2年就可发育进入羽化分飞的成熟年龄,分离时间对产生羽化分飞的历期有一定影响,6月分离的多品级分离群体产生羽化分飞的历期平均为659.3d。单品级翅芽若蚁分离群体可产生羽化分飞,且存在反季节羽化现象。

Mature, segregated colonies of Reticulitermes chinensis Snyder were reared in a laboratory. Both single-caste and multiple-caste colonies all could produce substitute reproductives ; the rate of production was positively correlated with colony size. The date and temperature when the colony was segregated significantly influenced the duration of production of substitute reproductives. The duration of producing substitute reproductives in January, April, June, September was 78.50 d, 46. 00 d, 32. 17 d and 26.00 d, respectively. Analysis of variance indicates a significant （P 〈 0. 05） difference between these durations. Segregated colonies rapidly underwent eclosion-swarming up to 2 years after the removal of the queen. The date on which the colony was segregated had some influence on eclosion-swarming. The average duration during which multiple-caste segregated colonies underwent eclosion-swarming in June was 659.30 d. Single-caste wing- bud nymph colonies underwent eclosion-swarming and also displayed reverse-season eclosion-swarming.
