Abstract

Eight eudesmane and eremophilane sesquiterpenes administered to Tribolium castaneum larvae caused different allelochemical effects. Topical application of 3-oxo-gamma-costic acid produced the greatest lengthening in the duration of the pupal stage. Morphological deformities were found, specifically when ilicic, costic, and gamma-costic acids and costic aldehyde were used. Ilicic acid exhibited the major toxicity 72 hr following topical application. All compounds were significantly toxic at the end point of the experiment (60 days). Treated surface toxicity was lower than when topical assays were carried out. Responses to tessaric acid in choice bioassays had the highest attractive effect. Maximum repellency was caused by the 3-oxo-gamma-costic acid. However, experimental series carried out using gamma-costic acid, eremophilan-1(10),2,11(13)-trien-12-oic acid, costic aldehyde, and ilicic aldehyde showed no clear response.

摘要

对赤拟谷盗幼虫施用八种桉烷型和雅槛蓝烷型倍半萜烯会产生不同的化感效应。局部施用3-氧代-γ-木香酸会使蛹期持续时间延长最多。发现了形态畸形，特别是在使用异土木香酸、木香酸、γ-木香酸和木香醛时。局部施用72小时后，异土木香酸表现出主要毒性。在实验终点（60天）时，所有化合物均具有显著毒性。处理后的表面毒性低于进行局部试验时的毒性。在选择生物测定中，对特沙酸的反应具有最高的吸引作用。最大驱避作用由3-氧代-γ-木香酸引起。然而，使用γ-木香酸、雅槛蓝-1(10),2,11(13)-三烯-12-酸、木香醛和异土木香醛进行的实验系列未显示出明显反应。
