(1) Background: Genistein is a naturally occurring flavonoid with a rich spectrum of biological activities, including plant-herbivore interactions. The aim of the study was to evaluate the effect of exogenous application of genistein on aphid behavior during probing in plant tissues. (2) Methods: , ssp. , and were treated transepidermally with a 0.1% ethanolic solution of genistein, and the probing behavior of generalist aphid species , , and was monitored on their respective treated and untreated host plants using electropenetrography (=electrical penetration graph technique, EPG); (3) Results: Genistein did not deter aphid probing activities in non-phloem tissues. In and , a trend towards reduction and in a trend towards increase in phloem sap ingestion occurred on genistein-treated plants, but these trends were not statistically significant. (4) Conclusions: Genistein is not a deterrent chemical against generalist aphid species studied; therefore, it is not recommended for practical application.
(1) 背景：金雀异黄素是一种天然存在的类黄酮，具有广泛的生物活性，包括植物与食草动物的相互作用。本研究的目的是评估外源施加金雀异黄素对蚜虫在植物组织中取食时行为的影响。(2) 方法：用0.1%的金雀异黄素乙醇溶液经表皮处理大豆、菜豆和蚕豆，使用刺探电位图谱技术（EPG）监测多食性蚜虫物种豌豆蚜、桃蚜和蚕豆蚜在各自处理和未处理的寄主植物上的取食行为；(3) 结果：金雀异黄素并未阻止蚜虫在非韧皮部组织中的取食活动。在豌豆蚜和蚕豆蚜中，经金雀异黄素处理的植物上韧皮部汁液摄取有减少趋势，而在桃蚜中有增加趋势，但这些趋势均无统计学意义。(4) 结论：金雀异黄素对所研究的多食性蚜虫物种并非驱避性化学物质；因此，不建议将其用于实际应用。
