Abstract
[Objective] The aim was to discuss the predatory functional response and catching effect of Propylea japonica to Anaphothrips obscurus. [Method] The predatory functional response and catching effect of P. japonica adult and its 2nd instar to A. obscurus were studied by laboratory experiment. [Result] The predatory functional response of P. japonica fitted Holling-Ⅱequation. The predation amount of P. japonica adult and its 2nd instar to A. obscurus adult was increased with the increment of pray density and the catching effect was decreased with the increment of pray density. Under the same pray density, the predation amount of P. japonica adult was more than that of its 2nd instar. Under the same A. obscurus density, the catching effect of P. japonica adult was higher than that of its 2nd instar. The upper predation of P. japonica adult and its 2nd instar to A. obscurus adult were 73.5 heads and 16.2 heads, resp. [Conclusion] The research laid the foundation for field control of P. japonic to A. obscurus.关键词
