从鹰嘴豆（Cicerarietinum）的野生近缘种中分离的四种抗虫素，在100 ppm浓度下对棉铃虫幼虫有拒食作用，尤达菌素和金合欢素分别在50 ppm和10 ppm浓度下对棉铃虫幼虫有拒食作用。在组合和与绿原酸的组合中测试了青蒿素;含有judaicin和maackiain的组合是最活跃的，并且绿原酸增强了所有四种青蒿素的拒食活性。H.阿尔米盖拉是四个军团中唯一一个被所有四个军团威慑的军团。单用Judaicin和S. frugiperda由maackiain单独。Heliothis virescens和S.甜菜没有被任何一种昆虫阻止进食。当加入到饲料中时，甜菜碱降低了H. armigera比后来的stadia，maackiain和judaicin是最有效的。因此，本研究认为，黄芩苷，尤其是槐素和菊素，可能在降低Cicer对H. armigera。
Four recently identified isoflavonoids, isolated from wild relatives of chickpea, Cicer arietinum, were shown to deter larval feeding by Heliocoverpa armigera at 100 ppm, judaicin and maackiain retained their antifeedant activity at 50 ppm and 10 ppm, respectively. The isoflavonoids were tested in combinations and with chlorogenic acid; the combinations containing judaicin and maackiain were most active, and chlorogenic acid enhanced the antifeedant activity of all four isoflavonoids. H. armigera was the only one of four noctuids to be deterred by all four isoflavonoids. Spodoptera littoralis was deterred by judaicin alone and S. frugiperda by maackiain alone. Heliothis virescens and S. exigua were not deterred from feeding by any of the isoflavonoids. When incorporated into a diet, isoflavonoids decreased the weight gain of early stadia larvae of H. armigera more than they did later stadia, and maackiain and judaicin were most potent. We conclude that the isoflavonoids, especially maackiain and judaicin, could play a role in decreasing the susceptibility of Cicer to attack by H. armigera.
