Screening host plant for Myzus persicae (Sulzer) in large-scale propagation of Aphidius gifuensis Ashmaed in Ji’an tobacco-growing areas
摘要
Abstract
To assess the appropriate host plants for Myzus persicae (Sulzer) in the large-scale propagation of Aphidius gifuensis Ashmaed in Ji’an tobacco-growing areas, the daily oviposition, developmental duration and propagation quantity of M. persicae, aphid parasitization rate and emergence rate of A. gifuensis on three host plants (tobacco, rape and pakchoi) were compared. The results showed that the daily oviposition of M. persicae on pakchoi was slightly higher than on tobacco and rape, but the difference was not significant. At early growing stage of aphid, the developmental duration of M. persicae on the three plants did not significantly differ, while it varied remarkably at middle and late growing stages. In general, the developmental duration on tobacco was the shortest. On the 12th day after aphid inoculating, the propagation quantities of M. persicae were clearly different on the three plants, the aphid propagation quantity on tobacco was the most with the fastest growth rate. The aphid parasitization rate by A. gifuensis on tobacco was significantly higher than on rape and pakchoi. The emergence rate of A. gifuensis was not significantly different on the different plants.关键词
