Biology
|
Gall
former on the leaves, petioles and twigs of the Coral tree Erythrina
latissima (Fabaceae). Three described species of
Aprostocetus and
3 other described species of Quadrastichus are associated
with Erythrina galls (Prinsloo & Kelly 2009). In addition a
species of
Eurytoma erythrinae is believed to be a parasitoid of
the eulophid gall inducers (Gates & Delvare 2008).Aprostocetus
exertus and
Eurytoma erythrinae have the potential to act as biocontrol
agents of the Erythina Gall Wasp
Quadrastichus
erythrinae,
which is rapidly spreading around the world (La Salle
et al. 2009). |
