Azinphosmethyl, spinosad, thiacloprid, esfenvalerate and indoxacarb were evaluated in the laboratory for contact toxicity to apple maggot flies during a 10-min exposure treatment. LC50 and LC90 values (ppm) were established as 108.0 and 115.0 for azinphosmethyl, 21.0 and 35.5 for spinosad, 59.7 and 108.2 for thiacloprid, and 84.3 and 256.0 for esfenvalerate. No LC50 and LC90 could be established for indoxacarb because of its little contact toxicity. Compared with field rates, azinphosmethyl was most toxic, followed by spinosad, which was more toxic than thiacloprid and esfenvalerate.
