Host Plant Species of Bemisia tabaci Affect Orientational Behavior of the Ladybeetle Serangium japonicum and Their Implication for the Biological Control Strategy of Whiteflies.

摘要: Serangium japonicum Chapin (Coleoptera: Coccinellidae) is a predominant predator with preference for Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae). To date, the orientational behavior of S. toward B. tabaci-infested plants has seldom been reported. In this study, greenhouse cage experiments and bioassays wind tunnels, Y-tube olfactometer tabaci-induced plant volatiles were executed to clarify behavior. experiments, adults significantly preferred eggplant, cucumber tobacco cotton tomato, whereas tomato. tunnel bioassays, showed clear tobacco. Compared or cotton, was rarely visited by japonicum. did not distinguish between uninfested eggplant. Nine common detected in different species, suggesting that these may play an important role process which looks prey. light current results, we discuss implications our findings put forward new strategy—i.e., eggplant + system—to control damage integrated management whitefly.
