| Abstract: | Abstract. 1. The paper describes the population dynamics of Prays citri (Milliere), relevant to the control of this pest by synthetic pheromone, as well as infestation of lemon trees in various areas and seasons. 2. The responses of males to natural and synthetic sex pheromones are compared, and ratios for the degree of attraction of traps compared with the degree of attraction of competing wild females are calculated. 3. The ratios obtained with various population densities over two seasons of the pest's activity are presented. 4. The data are used in a model simulating control of Prays citri by male mass trapping. |
