A total of 73 ethanol extracts from different anatomical parts of 44 plant species belonging to 24 families, native to the Mid-Western region of Brazil, were assessed in vitro for their effect on the reproductive cycle of engorged females of the cattle tick Rhipicephalus (Boophilus) microplus, using the adult immersion test. All extracts were evaluated at the concentration of 0.2 % and, among the extracts tested, the one obtained from the fruits of Guarea kunthiana (Meliaceae) proved to be highly efficacious, showing 99.1 % of product effectiveness. Extracts from other three species were shown to be moderately active, namely Nymphaea amazonum trunk (Nymphaeaceae) [51.7 %], Strychnos pseudoquina trunk (Loganiaceae) [48 %] [corrected] and Ocotea lancifolia leaves (Lauraceae) [34.5 %], while the remaining extracts were shown to be weakly active or inactive. This is the first report on the bioactivity of these species on egg production by engorged females of R. microplus.
总共对来自巴西中西部地区的 24 个科的 44 种植物的 73 种乙醇提取物进行了评估，这些植物的不同解剖部位属于 24 个科，采用成虫浸泡试验，评估其对已饱血的牛蜱 Rhipicephalus (Boophilus) microplus 雌虫生殖周期的影响。所有提取物均在 0.2%的浓度下进行评估，在所测试的提取物中，从瓜拉那果实（桃金娘科）中获得的提取物效果非常好，产品有效率达 99.1%。其他三种植物的提取物表现出中度活性，即亚马逊王莲树干（睡莲科）[51.7%]、假奎宁树干（马钱科）[48%] [更正]和月桂叶（樟科）[34.5%]，而其余提取物则表现出弱活性或无活性。这是关于这些物种对已饱血的 R. microplus 雌虫产卵的生物活性的首次报道。
