of the damage by PC to fruit sampled at harvest may 

 be as a consequence of re-mfestations that occurred 

 after the petal-fall spray of insecticide. It would be very 

 important to detemiine, under sprayed conditions, the 

 extent to which PCs show this type of back-and-forth 

 movement after the petal-fall application of insecticide. 

 More research is also needed to determine what type 

 of factors (e.g., weatherand tree size) influence this 

 behavior.
