The rate of reduction was studied at various prey and predator densities. The food activity of spiders, as well as the relative activity and distribution of mosquitoes in the isolator, were analysed in various relations of prey and predator density. The authors studied the effect of the spider and mosquito reactions mentioned on prey reduction. Besides, the modyfying effect of vegetation structure in the isolators and of different periods of the season when the experiments were carried out was taken into account in its bearing on the character and rate of prey reduction.
