Two wild mated female Medflies were detected, and reported to APHIS by the California Department of Food and Agriculture from a residential area of Rancho Cucamonga, San Bernardino County on September 23, 2005. The detection was confirmed as wild mated females on September 27, 2005 and is within the sterile Medfly Preventative Release Area program area. Analyses are being performed to attest if the wild females were mated with sterile males. The detection is within 4 miles of the Ontario airport.
Foliar treatment, using protein bait spray (Spinosad), will be applied to all host trees within 200 meters of the detection. The rate of aerial sterile fly release will be increased to 250,000 sterile male Medflies per square mile per week in a 9 sq mile area surrounding the infested property.
