Abstract

There is currently growing interest in knowing how predators relate to their environment, which includes relationships between the predators themselves and between them and their prey. Nesidiocoris tenuis y Orius laevigatus are two predators successfully used for control numerous pest species in horticultural crops. In this work the objective was analyze the influence of the prey Spodoptera exigua eggs density in intragremial interaction these two predators species and establish what extent they interaction affect the control pest potential. The intragremial interaction between N. tenuis and O. laevigatus was positive with regard they consumption capacity, at low S. exigua eggs density, and at high eggs density was negative. Likewise, the interaction occasion a high mortality of the two predators, regardless of the density of prey. These results should be considered for the joint use of these predators in biological control pests strategies, specifically of S. exigua
