Identification and control of tomato pinworm, Keiferia lycopersicella Walsingham, with Melia azedarach L. extracts on tomato in San Luís Potosi, Mexico

 M. azedarach extracts were evaluated in order to know their effect on tomato pinworm larvae. The study was done in the municipality of Rio Verde. Pinworm species correspond to Keiferia lycopersicella, considering the structure of male genitalia. Two leaf extracts at 5 and 10%, two fruit extracts at 5 and 10%, and the control (without extracts) were evaluated. SAS 9.0 was used for the results analysis. Fruit extracts were more effective than leaf extracts at the same concentration. Keiferia lycopersicella is the only species of Gelechiidae attacking tomato crops in the State of San Luis Potosi, Mexico.
