STATE POMOLOGICAL SOCIETY. 1 59 



In view of the fact that orcharding is one of the chief inter- 

 ests of the State, the Experiment Station has the orchard con- 

 stantly in mind with reference to insects of economic impor- 

 tance. The principal orchard insects of Maine are practically 

 well known so far as their life histories and remedial measures 

 are concerned. In order that this knowledge may be shared 

 by anyone in the State who is interested, the Station has always 

 on file the following circulars upon insects which are concerned 

 with the apple tree, — root, trunk, branch, leaf, blossom or fruit :

These circulars are sent as replies in full to persons submit- 

 ting any of these insects for identification. 



While the available circulars include only a small number of 

 the multitude of apple insects, yet if the orchards are so treated 

 as to combat the serious pests, the multitude of lesser evils 

 need not be feared, for they will for the most part succumb 

 incidentally to the treatment given to the really dangerous 

 insects and thus many species may be killed with one treatment. 

 Moreover the remedial measures against the standard pests 

 overlap. For instance, the destruction of windfalls by pastur- 

 ing orchards with hogs is a measure directed at once against 

 3 of the worst apple insects in the State — the apple maggot, the 

 curculio and the codling moth; or removing colonies while 

 young and still gregarious includes the red-humped caterpillar, 

 the yellow-necked caterpillar, the tiger caterpillar and others.
