 Department of Entomology 



A conference on apple maggot research in the Northeastern 

 United States and Canada was held on March 27-28, 1974, at the New 

 York State Agricultural Experiment Station, Geneva, New York. 

 Twenty-seven participants in this area of research attended, includ- 

 ing 6 Canadians. 



Topics covered included: 



1. Apple Maggot Population Monitoring. The relative effec- 

 tiveness, spacing and positioning of various traps. Uses of traps 

 in orchard monitoring. Improvement and future development of moni- 

 toring systems. 



2. Apple Maggot Management and Control. Chemical control, al- 

 ternate control measures (habitat manipulation, trapping, hormones 

 and pheromones, and male sterile release programs). 



3. Laboratory and Mass Rearing Techniques . Artificial diets, 

 handling techniques, and artificial oviposition systems.
