【摘要】 本文主要研究温、湿度因子对家白蚁初建群体的影响,实验指出家白蚁初建群体对温度及栖息地基质含水量要求严格,温度过高或过低都不利于种群发展,在20℃定温环境下,虽然能产几粒卵,但不能孵化。在25℃定温虽能产卵,但推迟孵化,影响以后种群数量的变动。家白蚁初建群体还要求基质含水量适中,过低的基质含水量,产卵量少且不能孵化,基质含水量过高,雌、雄虫死亡率亦高。实验室内要求的条件与野外群体飞行时要求的温湿度条件基本上是吻合的。更多还原

【Abstract】 The present paper deals with the influence of temperature and humidity on the initial colonies of Coptotermes formosanus Shiraki.The results indicate that incipient colonies of C. formosanits need optimal temperature and humidity.If the temperature is higher than the optimum or below it, the development of the colonies is inhibited.Eggs hatched at 30℃. At 25℃ the females can lay a few eggs, but the incubation period become longer. Although they can lay a few eggs at 20℃, but the eggs fail to hatch. At 15℃ they can not lay eggs until death.The incipient colonies of C. formosanus choose optimal temperature for flight. They also require the suitable water content in the food media. Below optimal condition, the number of eggs deposited decreases and they fail to hatch. If the humidity is higher, the incubation period becomes longer, and the mortality of adults is also higher.更多还原
