Third-instar German cockroach nymphs were held to maturity in continuous proximity to test surfaces treated with hydroprene and fenoxycarb, which they were unable to contact directly. Surfaces tested were unfinished plywood, fiberboard, vinyl tile (absorbent surfaces), glass, stainless steel, ceramic tile, and formica (nonabsorbent surfaces). Number of oothecae, percent egg hatch, and survival did not differ between any fenoxycarb treatment and the untreated controls, but there was significant wing twisting (76-94%) for all nonabsorbent surfaces. Number of oothecae was significantly lower and percent wing twisting was significantly higher for all hydroprene-treated surfaces with respect to the untreated controls, although survival was not affected. These effects were less pronounced for the nonabsorbent surfaces. These results indicate that hydroprene, but not fenoxycarb, has significant biological activity through volatile action when applied at current label rates. This activity is likely to have important consequences for control, especially for "crack and crevice" applications in confined spaces.
将三龄德国小蠊若虫饲养至成熟，使其持续接近用烯虫酯和苯氧威处理过的测试表面，但它们无法直接接触这些表面。测试的表面有未处理的胶合板、纤维板、乙烯基瓷砖（吸水性表面）、玻璃、不锈钢、瓷砖和富美家（非吸水性表面）。在任何苯氧威处理组与未处理的对照组之间，卵鞘数量、卵孵化率和存活率均无差异，但所有非吸水性表面均出现了显著的翅扭曲（76 - 94%）。与未处理的对照组相比，所有用烯虫酯处理过的表面的卵鞘数量显著减少，翅扭曲百分比显著升高，尽管存活率未受影响。这些影响在非吸水性表面上不太明显。这些结果表明，按照当前标签用量施用时，烯虫酯而非苯氧威通过挥发作用具有显著的生物活性。这种活性可能对防治有重要影响，尤其是在密闭空间中的“缝隙和孔洞”施药方面。
