in the fall, dnd in the mornings a little glisten of dew on the 

 edge of the leaves, and if you looked at them closely, you 

 would find it to be honey dew. 



The pear psylla is a very small insect. The only insect 

 that I can compare it with and with which perhaps you are 

 dJl acquainted is the cicada. The pear psylla is like the cica- 

 da in shape and appearance, only it is about possibly 1-200 

 part as large. It is very small. 



It stays during the winter on our trees in the adult stage, 

 usually hiding underneath the bark. If you examine the 

 trees closely on a sunny day on th." south side and lift up 

 some of the bark, you will find it very active, — moving very 

 quickly. For that reason we find that during the month of 

 Novembe r we can partly control the pear psylla by spraying 

 with lime-sulfur during those days when the thermometer 

 runs to about 40, because the pear psylla usually moves out 

 from underneath the bark of the trees to sun itself, and you 

 can get a fairly good percentage of them at that time. 



The trouble is that there does not seem to be any time 

 when Ave can get a large enough per'-entage of the insects to 

 control it. 



Then, in the spring, just as the blossom buds — the clus- 

 ter — separates, the pear psylla begins laying its eggs, and 

 those may be destroyed or partially controlled, but it i'« al- 

 most impossible to control them all. because they are usuall^' 

 placed underneath the bud scales and are not all exposed. 



Then later on in the season when we spray before the 

 blossoms open and after the petals have fallen off, if we' use 

 Black-leaf-40 in those two conditions we will usually get some 

 more of them. But even with those three or four applica- 

 tions and trying the best we can, I haven't found anyone yet 

 that has been able to keep them entirely under control, so be- 

 fore fall again, you have got a bad infestation of pear psylla. 

 I think it is a subject we ought to investigate more thor- 

 oughly, and if we are going to grow any pears in this state 

 at all. we ought to try and find some solution for it.
