Technical Abstract: Asian citrus psyllids (ACP) are the most serious pest of citrus worldwide. This invasive pest is the vector of Candidatus Liberbacter asiaticus (Las) which causes citrus greening. As rates of inoculation of Las by ACP increase proportionally to the number of infected ACP feeding on a plant, study of the ecology of ACP is crucial to management ACP populations in citrus groves. Little is known of the population dynamics of ACP in the grove, which can undergo violent fluctuations in abundance by rapidly exploiting their environment when limiting factors are relaxed, due to their high fecundity and short life cycle. Furthermore, ACP population dynamics have not been related to both community and environmental factors in multiple groves. The purpose of this study was: 1) to identify compare seasonal trends in adult population density in two citrus groves in south west Florida; 2) determine the degree to which environmental and community factors correlate with adult ACP density and nymph infestation within the same groves. Data obtained over a 3 year long term monitoring program in Immokalee, Fl was utilized to provide estimates for seasonal trends accounting for multi-year variability.
