Mechanisms of Feeding Deterrence by Ziziphins.

Abstract

The mechanism of feeding deterrence by ziziphins for southern armyworms (Spodoptera eridania; Lepidoptera:Noctuidae) was investigated using both long-term, two-choice and no-choice measures, and short term (20 min) high magnification video analysis. Ziziphus jujuba leaves and leaf extracts are non-preferred in two-choice tests, and only eaten sparsely and sporadically, with long initial delays, in no-choice tests. In short-term tests, treatment of mouth parts with ziziphins significantly reduced total time feeding and feeding bout duration, compared to classical deterrent and carrier treatments. Time feeding decreased after ziziphins treatment while time crawling, time searching, and quiescent increased. A taste modifying action of ziziphins may account for this. Originator supplied keywords: tase modifiers, video analysis, larvae.
