 DOING ON INSECT PESTS OF APPLES? 



John G. Stoffolano, Jr.

Amid the great concerns about safe and efficient use of pesti- 

 cides, fruit growers rightly ask what type of research is being 

 done by entomologists today to resolve these concerns. During 1974, 

 I attended 4 national conferences of entomologists, at which a num- 

 ber of papers were presented that are of direct interest to growers. 

 A report on one of these meetings, the Apple Maggot Conference, was 

 published in Fruit Notes , July-August, 1974. An analysis of the

Among the 4 meetings, 14 papers were presented on topics deal-

 pest; 4 were on pest management; 3 were on pheromones [sex attrac-

tants) ; 1 was
