In apple orchards in Ontario, Quebec, and Nova Scotia yellow Sectar Pull-down traps prebaited with a mixture of HyCase protein hydrolysate, ammonium acetate, and adhesive trapped significantly more Rhagoletis pomonella (Walsh) adults than did Sectar 1 yellow traps prebaited as before or Pherocon ICPY baited with a solution of soy hydrolysate and ammonium acetate. The largest number of flies was caught with Sectar Pull-down traps, and 1st capture was significantly earlier than with the others. Nontarget insects, of which ca. 95% were Diptera, accounted for ca. 70, 25, and 5% of all captures on Sectar Pull-down, Pherocon, and Sectar 1 traps, respectively. The use of prebaited yellow traps of the Pull-down design, obtained from Zoecon Corp., to time 1st spray and later applications resulted in fewer sprays than are presently recommended in orchards with low or moderate apple maggot populations.
