First discovery of Selitrichodes neseri in the field

Biocontrol agent for eucalyptus gall wasp released

It was with great excitement that we found the first Selitrichodes neseri wasp emerging from Leptocybe-infested material collected in the field. This material was collected from a site in Mtunzini, Zululand, where S. neseri was released in September this year. The finding of S. neseri in the field shows that the wasps released at that site were able to successfully locate and parasitize their host (Leptocybe invasa) and produce healthy offspring. This discovery is an important step in confirming the ability of S. neseri to act as an effective biocontrol agent for L. invasa. Samples from this and other release sites will be continually monitored every two months to investigate the establishment success and rate of spread of S. neseri.

Further information about S. neseri and the releases can be found in the attached article that will appear in the next issue of the TPCP newsletter.
