6 MAINE AGRICULTURAI, EXPERIMENT STATION, 



Codling Moth (Carpocapsa pomoneUa.) 

 Although this insect nowhere in the State is so significant a 

 pest as the two just mentioned, it needs to be guarded against 

 and can be by proper spraying as explained elsewhere in this 

 paper. 



INSECTS DEVELOPING BY CHEWING LEAVES. 



Mottled Fruit Caterpillar (Crocigrapha norniani). 

 A caterpillar not before recorded as an orchard pest was 

 discovered by us to feed upon apple, — both leaves and green 

 fruit. Arsenical sprays. 



Saddled Prominent Caterpillar {Heterocampa guttivitta)'. 



A sj)ecies never before recorded as an injurious insect 

 stripped many orchards and forest growths of Maine during a 

 few years attack. We worked out the total life cycle of this 

 insect, gave it its popular name, studied its color variations, 

 parasites, and its collapse under bacterial and fungous disease. 

 Arsenical spray sufficient to protect the orchard. 



Brown-tail Moth {Biiproctis chrysorrhoea). 



The first scouting to ascertain the limit of infestation by the 

 Brown-tail Aloth and the initial educational campaign concern- 

 ing this insect was undertaken by this Station. There seems to 

 be no limit to the instruction desired in this connection as the 

 people of York County are still sending in Brown-tail Moths in 

 dififerent stages for identification. 



Besides the foregoing species the following apple caterpillars 

 have been published by this Station with descriptions, habits 

 and effective remedies in each case practical for orchard use : — 



Apple-leaf Bucculatrix, Bucculatrix pomifoliella. 



Apple Leaf-sewer, Ancylis nuheculana. 



Ash-gray Pinion, Lithophane antennata. 



Bud Moth, Tmetocera ocellana. 



Canker Worms : Fall, Alsophila pometaria; Spring, Palea- 

 crita vernata. 



Cecropia, Samia cecropia. 



Cherry-tree Tortrix, Archips cerasivorana.
