Abstract

The egg parasites of citrus root weevil complex of the Caribbean and Florida have been known to contribute appreciably to the control of these pests for decades. In Jamaica however, no emphasis was placed on developing biological control strategies as chemical pesticides had the confidence of the citrus industry. Field sampling of egg masses for parasitism levels at two plantation sites from August 1990 to April 1993 showed levels of 94 % and 71 % for United Estates, St. Catherine and Greenwood Farms, St. Mary respectively. Since April 1991,139, 160 F. citri and 197,850 A. haitiensis have been released at United States. Assessment of release activities showed higher parasitism levels in areas where releases were can·ied out though these observations were not consistent over time.
