在感染真菌内生菌（枝顶孢属，Acremonium spp.，和Epicheliotyphina）。34个宿主真菌协会中有29个产生一种或多种生物碱，最常见的是peramine或ergovaline。在感染A.而peramine、lolitrem B和ergovaline在感染A. coenophialum和A. lolii产生相似的生物碱模式，无论他们感染的草的种类或品种，E. typhina在所测试的草中不产生生物碱或仅产生一种或两种不同的生物碱。蚜虫生物测定结果表明，禾谷缢管蚜和麦二叉蚜不能在含黑麦草碱的禾本科植物上存活，麦二叉蚜在含黑麦草碱的禾本科植物上存活。禾本科植物不能在含peramine的草上存活。含麦角缬氨酸的草不影响蚜虫。
The occurrence of the alkaloids N-formyl and N-acetyl loline, peramine, lolitrem B, and ergovaline and the response of aphids to plants containing these compounds were determined in species and cultivars of Festuca, Lolium, and other grass genera infected with fungal endophytes (Acremonium spp., and Epichloe typhina). Twenty-nine of 34 host-fungus associations produced one or more of the alkaloids, most frequently peramine or ergovaline. Three alkaloids (lolines, peramine, and ergovaline) were found in tall fescue and in perennial ryegrass infected with A. coenophialum, while peramine, lolitrem B, and ergovaline were present in perennial ryegrass and in tall fescue infected with A. coenophialum and A. lolii produced similar patterns of alkaloids regardless of the species or cultivar of grass they infected, isolates of E. typhina produced either no alkaloids or only one or two different alkaloids in the grasses tested. Aphid bioassays indicated that Rhopalosiphum padi and Schizaphis graminum did not survive on grasses containing loline alkaloids and that S. graminum did not survive on peramine-containing grasses. Ergovaline-containing grasses did not affect either aphid.
