Here, we describe the biology of a relatively new pest cockroach species in Southeast Asia, Symploce pallens (Stephens) (Dictyoptera: Blattellidae). S. pallens collected from Penang Island, Malaysia, were used for the biological parameter studies and were observed for molting and reproduction events. Nymphal development took 118.2 +/- 1.7 d, with a mean of 9.5 +/- 0.1 molts. The oothecal incubation period was 36.1 +/- 0.2 d. Females produced a mean of 16.0 +/- 10.2 oothecae, with mean 17.6 +/- 0.1 nymphs per ootheca. Nymphal survivorship per ootheca was 90.4%, and 90.7% of nymphs achieved adulthood. The sex ratio did not deviate from 1:1. The mean longevity of adult males and females was 309.3 +/- 7.6 and 322.6 +/- 14.8 d, respectively. In general, S. pallens exhibited higher oothecal production and longer nymphal development and longevity compared with the German cockroach, Blattella germanica (L.).
在这里，我们描述了东南亚一种相对较新的害虫蟑螂物种——苍白弓背蚁（Symploce pallens）（直翅目：蜚蠊科）的生物学特性。从马来西亚槟城岛采集的苍白弓背蚁用于生物学参数研究，并观察其蜕皮和繁殖事件。若虫发育需要 118.2 +/- 1.7 天，平均蜕皮 9.5 +/- 0.1 次。卵鞘孵化期为 36.1 +/- 0.2 天。雌虫平均产 16.0 +/- 10.2 个卵鞘，每个卵鞘平均有 17.6 +/- 0.1 个若虫。每个卵鞘的若虫存活率为 90.4%，90.7%的若虫达到成虫期。雌雄性别比例为 1:1。雌雄成虫的平均寿命分别为 309.3 +/- 7.6 和 322.6 +/- 14.8 天。总体而言，苍白弓背蚁的卵鞘产量较高，若虫发育和成虫寿命较长，与德国蟑螂（Blattella germanica）相比。
