AN OVERVIEW ON SOME BIOTIC AND ABIOTIC FACTORS AFFECTING THE POPULATION DYNAMICS OF LEUCAENA PSYLLID, Heteropsylla Cubana Crawford (HOMOPTERA: PSYLLIDAE): CONTRIBUTORY FACTORS FOR PEST MANAGEMENT

The present review was written with the objectives of providing basic information for pest control about leucaena psyllid, Heteropsylla cubana Crawford (Homoptera: Psyllidae) the most destructive insect pest of Leucaena sp. In the regard of pest control, the review focus on discussing the findings of the existing researches about the factors affecting the distribution and seasonal fluctuations of H. cubana in the world. These factors are biotic such: biological control agents, and abiotic such: climatic factors, leaves chemical composition and genetic control which significantly affect pest population. A basic understanding of the relationship of these factors with psyllid population is important in developing an integrated control strategy for psyllid in leucaena and determining the potential pest control needs under the given biotic and abiotic factors trend. Besides, develop some concepts of pest control which effect directly and indirectly on the survival and population dynamics of H. cubana around the world.
