European apple sawfly (EAS). We examined 

 100 or 200 leaves or terminals per block for 

 leafminers (eggs and mines), leafhoppers, mites, 

 and mite predators. Fruit were examined by 

 both IPM scouts and growers for fresh plum 



curculio (PC) injury. Based on this monitoring, 

 recommendations were made to the grower for 

 treatment of the experimental block. Combined 

 injury from early season fruit pests was similar 

 in first- level IPM (grower control) blocks and in
