Oviposition site preference and developmental performance of a gall-inducing leafhopper on galled and non-galled host plants

摘要: Oviposition preferences of herbivorous insects affect offspring performance. Both positive and negative links between oviposition preference performance have been reported for many species. A gall-inducing leafhopper, Cicadulina bipunctata Melichar (Hemiptera: Cicadellidae), feeds on various Poaceae plants induces galls enhanced nutritional value their offspring. Although gall induction by C. bipunctata improves nymphal performance, the females galled non-galled host is still unclear. In this paper, feeding-site were investigated using wheat, Triticum aestivum L., barley, Hordeum vulgare as plants. The survival rate wheat was significantly higher than barley. choice test, more eggs laid into whereas number deposited both hosts not different in no-choice test. settling individuals per leaf area suggesting no clear these Experience a nymph with growing did adult female. inconsistent correspondence may reflect high mobility nymphs and/or differences results indicate that previous finding are always positively correlated applicable to insects.
