A mathematical method for determining the optimal quantity of natural enemies of a pest species to raise. (Chinese. English summary) Zbl 1055.92519

Summary: A dynamic model of pests’ population quantity with random rise and fall as the environment varies was evaluated by using the methods of Itô stochastic differential equations. A formula to determine the optimal quantity of the pests’ natural enemies for biological control was proposed by using the method of finding the minimal value, and a statistical method to determine the parameters in the formula was pointed out.
