Goals / Objectives
Conduct foreign exploration for natural enemies of the Olive Fruit Fly from a variety of areas.
Project Methods
Conduct bioclimatic matches with central California olive production zones of the olive species. Genetic finger printing will be utilized with taxonomic identification of natural enemies. Develop rearing methods and biological studies.

4d Progress report. This report serves to document research conducted under a specific cooperative agreement between ARS and the Biotechnology and Biological Control Agency, Rome, Italy. Additional details of research can be found in the report for the parent CRIS 4012-22000-0219-00D,Discovery, Biology & Ecology of Natural Enemies of Insect Pests of Crops, Urban & Natural Areas. Explorations for olive fruit fly and its natural enemies were made in the Canary Isles, Morocco, South Africa, Namibia, tropical southern China and Kenya. Resulting parasitoids were recovered in the quarantine laboratory at USDA-ARS EBCL. Cooperative research agreements to ensure more collections and shipments of parasitoids were arranged with cooperators in Pakistan, India, Kenya, and China. Large numbers of the host-specific braconid parasitoid, Psyttalia lounsburyi, were collected from Kenya. P. concolor was obtained from 2 sites on Grand Canary Island and from two sites north of Agadir, Morocco; both these areas have similar climates to olive growing areas in California. Collections from southern Africa and Kenya included the braconids Bracon celer, Bracon spp., Utetes africanus, Psyttalia concolor, and P. lounsburyi. Populations of Psyttalia c.f. ponerophagus emerged from olive fly pupae collected in Pakistan, and several shipments of material were also received from cooperators in Kenya and China. Two shipments of following olive fly parasitoids were sent from EBCL quarantine to the UC Berkeley quarantine for host range testing: 1) Psyttalia lounsburyi (originally collected at Burguret Forest and Mt. Elgon, Kenya; 2) Psyttalia concolor/nr.concolor from Namibia; 3) Psyttalia concolor(?), Kenya; 4) Psyttalia c.f. ponerophaga from Cherat, Pakistan; 5) Utetes africanus from South Africa.

    4. What were the most significant accomplishments this past year? This report serves to document research conducted under an agreement between EBCL-USDA-ARS and the California Department of Food and Agriculture Biological Control Program. Field explorations, surveys and collections in support of ongoing research on natural enemies of the olive fruit fly were continued in South Africa, Kenya, and Pakistan, and were initiated in Namibia and La Reunion. Laboratory culture and biological evaluation of the parasitoid Psyttalia lounsburyi and P. concolor has continued. Live material of P. lounsburyi from culture and from field collections in Kenya, South Africa, and Namibia was shipped to cooperators in California and Italy for collaborative rearing and host- range studies.
