Description
Summary:Studies were conducted under controlled laboratory conditions to evaluate the effect of the predator, Zelus longipes (Hemiptera: Reduviidae) on mortality of Diaphorina citri (Hemiptera: Liviidae) as well as its effect on the specialized parasitoid, Tamarixia radiata (Hymenoptera: Eulophidae). All tested life stages of Z. longipes consumed significantly more D. citri adults than nymphs. Zelus longipes nymphs were only effective as predators of D. citri adults at a predator density of 8 individuals (or specimens) per arena. The mortality of D. citri nymphs caused by Z. longipes adult females was higher at the densities of 2 or more predators per arena. All densities of male and female adult Z. longipes resulted in mortality of nearly all the T. radiata adult parasitoids offered. The importance of intraguild predation and possible interference with T. radiata are discussed.
