Abstract

Diaphorina citri Kuwayama (Hemiptera: Liviidae) is the main vector of the bacteria that causes Huanglongbing (HLB), the most destructive disease of Citrus check for this species in other resources . The presence of D. citri was reported in Ecuador in 2013 on branches of citrus, Citrus spp., and orange jessamine, Murraya paniculata check for this species in other resources (L.) Jack (Rutaceae), but HLB has not been detected so far in this country. This paper reports for the first time the presence of two important natural enemies of D. citri in Ecuador, i.e., its main parasitoid Tamarixia radiata (Waterston, 1922) (Hymenoptera: Eulophidae) and the adventitious ladybird beetle Cheilomenes sexmaculata (Fabricius, 1781) (Coleoptera: Coccinellidae) attacking psyllid nymphs on M. paniculata, in Guayaquil, Guayas province, Ecuador. A short diagnosis of the two natural enemies and their distribution in the New World is presented based on published literature.
