STUDIES ON PREDATION AND SIMULATION MODEL OF DWARF SPIDER ERIGONIDIUM GRAMINICOLUM TOCOTTON BOLL WORM HELIOTHIS ARMIGERAII. STUDIES ON ONE-PREDATOR-MULTI-PREYSPECIES INTERACTING SYSTEM
草间小黑蛛对棉铃虫幼虫的捕食作用及其模拟模型的研究——Ⅱ.捕食者——多种猎物系统的研究

This paper suggests an equation to estimate the total amount of prey capturedand a method to estimate the parameter of preferencewhereand also a simulation model under the existing of an alternative food species (cotton aphid)The results of predation experiments carried out in big cages can be described by following the modelAnd the more the prey species exist with one predator species, the lower the predation rate to a special prey species is.The research on the behaviour of the simulation model shows some...
