(Diptera: Culicidae) is responsible for the transmission of lymphatic filariasis. The search for natural sources of new insecticides to control mosquitoes has intensified in recent years. is an exotic species in Brazil, known as 'ipê de jardim'. pericarps were extracted with hexane in Soxhlet apparatus, and fatty acids (FA) and methyl esters (FAME) were obtained by transesterification reaction of hexane extract (HE). HE, FA, and FAME were evaluated against 3 and 4 instar larvae of . Analysis by gas chromatography-mass spectrometry (GC/MS) identified the hydrocarbon nonacosane (81.69%) as the major compound in HE, and linolenic (16.89%), linoleic (16.83%), and palmitic acids (21.00%) were predominant in FA. FA and HE, at a concentration of 250 µg/mL, promoted mortality of 81.67% and 68.66% of larvae, respectively. HE and FA obtained from pericarps have larvicidal potential for the control of .
（双翅目：蚊科）负责传播淋巴丝虫病。近年来，人们加紧寻找天然来源的新型杀虫剂来控制蚊子。 在巴西是一种外来物种，被称为“花园朴树”。用索氏提取器用己烷提取 的种皮，通过己烷提取物（HE）的酯交换反应得到脂肪酸（FA）和甲酯（FAME）。HE、FA 和 FAME 用于评估对 3 龄和 4 龄 的幼虫的影响。气相色谱-质谱联用（GC/MS）分析鉴定出 HE 中的主要化合物是碳氢化合物二十九烷（81.69%），FA 中的主要脂肪酸是亚麻酸（16.89%）、亚油酸（16.83%）和棕榈酸（21.00%）。FA 和 HE 在浓度为 250μg/mL 时，分别使 81.67%和 68.66%的幼虫死亡。从 种皮中获得的 HE 和 FA 对 的幼虫具有杀幼虫潜力，可用于控制 。
