Association between Temperature and Reproductive Fitness of Diaphorina citri Infected with Candidatus Liberibacter Asiaticus

Diaphorina citri is a serious insect pest of citrus and an vector Candidatus Liberibacter asiaticus (CLas) that causes Huanglongbing disease (citrus greening). In this study, we investigated the effect CLas pathogen on life history parameters D. at different temperature regimes. Our results demonstrated survival rate first to fifth instar CLas-positive CLas-negative fluctuate with change in over range 16–35 °C. Meanwhile, mean developmental time (52.5 d) (d = day(s)) adult longevity (5.2 psyllids was longer as compared (32.81 (3.50 low- high-temperature regimes (16 35 °C). However, high regimes, significant CLas-bacteria fecundity higher than corresponding non-significant their survivorship when non-vectored psyllids. These indicate long-term, stable evolutionary relationship among vector-pathogen climate change.
