Diaphorina citri Kuwayama (Hemiptera: Liviidae) is the
main vector of the bacteria that causes Huanglongbing
(HLB), the most destructive disease of
Citrus
. The
presence of D.
citri was reported in Ecuador in 2013 on
branches of citrus,
Citrus spp., and orange jessamine,
Murraya paniculata
(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.
