Abstract

spp., entomopathogenic bacteria symbiotically associated with the nematodes and , occur in two forms. In general, only one form, designated the primary form, is transmitted into new hosts by the infective stage of the nematode. The significance of the relationship between the two forms has been examined with , the symbiont of The forms of can be differentiated by their colony characteristics but by only two biochemical tests. The two forms of are equally pathogenic when injected into the haemocoel of larvae. However, the primary form when injected into larvae with axenic nematodes provides better conditions for reproduction of the nematodes than the secondary form, for which a role has not been determined. Although the primary form readily converts to the secondary form and occasionally , the secondary form is usually stable. Possible causes of the instability have been investigated.
