Abstract

Maysin, a flavone glycoside from corn silks, inhibits ingestion, and thus growth, ofHeliothis zea (Boddie) larvae. Pinitol from soybeans inhibitedH. zea growth by the same mechanism. Despite the widely held assumption that tannins inhibit growth by inhibiting assimilation, cotton condensed tannin inhibitedH. zea growth by reducing ingestion; no evidence was found for a reduction in assimilation. Neonate larvae are shown to be much more sensitive to allelochemics than larvae that have fed on control diet before being transferred to diet containing plant allelochemics.

摘要

玉米丝中的类黄酮糖苷梅萨辛通过抑制取食来抑制玉米螟幼虫(Boddie)的生长。来自大豆的肌醇也通过相同的机制抑制玉米螟的生长。尽管人们普遍认为单宁通过抑制吸收来抑制生长,但棉花单宁却通过减少取食来抑制玉米螟的生长;没有发现吸收减少的证据。与幼虫在转移到含有植物化感物质的饲料之前先喂食对照饲料相比,初孵幼虫对化感物质更为敏感。
