Life tables for the guava psyllid Triozoida limbata in southeastern Brazil
BioControl 57 (6), 779-788
Abstract: The aim of this study was to identify, quantify, and determine the importance of biological control agents of the psyllid Triozoida limbata (Enderlein) (Hemiptera: Sternorrhyncha: Triozidae). Ecological life tables were developed during four periods to determine the critical stage and key mortality factors of this pest. Predation and parasitism were found to be the two major factors driving the population dynamics of this pest. The major predators of eggs and nymphs of first and second instars were coccinellids, predatory thrips, lacewings, ants, and spiders, while the major predators of third, fourth, and fifth instars were several species of predatory wasps and syrphids. The endoparasitoid Psyllaephagus sp. (Hymenoptera: Encyrtidae) parasitized fifth instar psyllids. The fifth instar was found to be the critical mortality stage of T. limbata, and key mortality factors include the parasitoid Psyllaephagus sp. and predatory wasps.
