Nerium oleander (Apocynaceae) is evergreen shrubs widely used for ornamental purpose in mediterranean region. The present investigation, revealed for the first time the insecticidal effect of ethanolic extract from leaves of this plant against 2nd instar larvae of the medically important false stable fly Muscina stabulans (Diptera: Muscidae). LC50 of the extract was 113.66 ppm. This dose delayed larval and pupal duration suppressed oviposition and decreased adult longevity of the survivors. Morphogenic abnormalities were recorded and photographed in larval, pupal and adult stages, which were produced from treating 2nd instar larvae with different concentrations of the extract.
夹竹桃（夹竹桃科）是一种常绿灌木，在地中海地区广泛用于观赏目的。本研究首次揭示了该植物叶片乙醇提取物对重要医学害虫厩腐蝇（双翅目：蝇科）二龄幼虫的杀虫效果。提取物的半数致死浓度（LC50）为113.66 ppm。该剂量延长了幼虫和蛹期，抑制了产卵，并缩短了存活成虫的寿命。对用不同浓度提取物处理二龄幼虫后产生的幼虫、蛹和成虫阶段的形态异常进行了记录和拍照。
