The Mediterranean fruit fly in California: taking stock

Medflies have been captured in California 11 different years since 1975, and every year since 1986. Ten eradication programs have been mounted against this pest at a cost of over $150 million. While considerable scientific debate still exists on the nature of the medfly problem in the state, most agriculturalists agree that the problem is probably long-term. This paper provides a brief historical background of the medfly in the state, reviews existing control technologies and outlines future research needs and directions.
