Abstract

Nymphs of the Oriental cockroach Blatta orientalis were exposed during the penultimate and final instars to vinyl tiles treated with the juvenile hormone analogue hydroprene. Adults moulting from these nymphs exhibited deformities such as twisted wings in both sexes and modified genitalia in females. Females with deformities were unable to produce viable oothecae. B.orientalis confined on tiles treated with hydroprene at rates of 25-100 mg/m2 did not reproduce. The treatment rate of 10 mg/m2 reduced fecundity and caused 47-57% of resultant adults to have deformities, but some adults reproduced successfully and population growth was not suppressed.

摘要

将东方蜚蠊（Blatta orientalis）的若虫在倒数第二龄和末龄时暴露于用保幼激素类似物烯虫酯处理过的乙烯基瓷砖上。由这些若虫羽化而来的成虫出现了畸形，如两性均有翅膀扭曲，雌性生殖器也发生了改变。畸形雌性无法产出可孵化的卵鞘。将东方蜚蠊饲养在用25 - 100毫克/平方米的烯虫酯处理过的瓷砖上时，它们无法繁殖。10毫克/平方米的处理剂量降低了繁殖力，导致47 - 57%的羽化后成虫出现畸形，但仍有一些成虫成功繁殖，种群增长未受到抑制。
