【摘要】 为了解截头堆砂白蚁Cryptotermes domesticus(Haviland)群体中不同品级、不同虫态的雌雄性比,本文研究了该种白蚁自行配对室温条件下饲养4年巢龄的实验群体与采集的自然群体的各个品级和不同虫态的雌雄性比。结果表明:自行配对室温饲养4年巢龄群体与自然环境群体中原始繁殖蚁、幼蚁、若蚁、兵蚁都有雌雄之分,其中自行配对室温饲养群体的原始繁殖蚁雌雄比例为1∶1,兵蚁雌雄比例为1∶1.24,幼蚁和若蚁雌雄比例为1∶1.46;自然环境群体原始繁殖蚁雌雄比例为1∶1,兵蚁雌雄比例为1∶1.15,幼蚁和若蚁雌雄比例为1∶1.43。更多还原

【Abstract】 In order to clarify the sex ratios(♀:♂)of different castes and immatures of Cryptotermes domesticus(Haviland),we investigated sex ratios of self-pairing four years old colonies and nests collected from the wild at room temperature in a laboratory and in wild colonies.The results show that primary reproductive termites,soldiers,larvae and nymphs in either laboratory or wild colonies were comprised of both females and males.Sex ratios in the laboratory colonies for primary reproductive termites and soldiers were 1∶1 and 1∶1.24,respectively,and 1∶1.46 for immature termites,including larvae and nymphs.In the natural colonies,the sex ratios of primary reproductive termites,soldiers and immature termites were 1∶1,1∶1.15 and 1∶1.43,respectively.更多还原
