Bacteria Associated with the Caribbean Fruit Fly1,2

Abstract

Attempts were made to identify bacteria normally associated with Anastrepha suspensa (Loew). Isolations (70), were made under aerobic conditions from apparently healthy field-collected larvae and larval trails in infested guavas, as well as from laboratory-reared eggs and larvae. Four different bacteria, Micrococcus sp. ( flavus -like), Erwinia sp., Pseudomonas sp., and P. ovalis Chester were encountered. Although possible, none were isolated with such regularity as to suggest an intimate symbiotic relationship.
