本文对规格化养殖的德国小蠊的生活史进行了观察。卵鞘呈长肾形,挟持在雌虫腹部末端,待若虫孵出后脱落,第一个卵鞘,平均孵出若虫40.20只,卵孵化率95.17%,卵鞘孵化率97.14%。若虫蜕皮五次,有6个龄期,发育历期为37.56天,存活率为55.98%。成虫雌、雄性比为1:0.811。雌虫一生产卵鞘4～10只,平均6.86个,第5个以后的卵鞘孵出若虫数逐渐下降。雌、雄虫寿命平均为203.89天、157.82天,单个饥饿雌、雄虫寿命下均为14.29天和8.50天。整个生活史需62.81天,一年可繁殖5代多,一对成虫的繁殖为1000亿只。
In this paper, the life history of cockroaches in normalized culture was observed. Oviparoid kidney shaped, held host in the abdomen of the female, until the nymphs hatch off, the first egg sheath, the average hatched nymph 40.20, egg hatching rate of 95.17%, egg sheath hatching rate of 97.14%. Nymph molting five times, there are 6 age, developmental duration of 37.56 days, the survival rate was 55.98%. Adult female, male ratio of 1: 0.811. Egg production of a female 4 to 10, an average of 6.86, after the 5th egg hatch nymphs gradually decreased. The average life expectancy of female and male was 203.89 days and 157.82 days, respectively. The average length of life of a single hungry female and male was 14.29 days and 8.50 days, respectively. The entire history of life takes 62.81 days, a year can reproduce more than 5 generations, a pair of adults breeding 100 billion.
