334 INSECTS INJURIOUS TO THE STRAWBERRY, 



ATTAOKINa THE IRUIT. 

 No. 201. — The Stalk-borer. 



Gortyna nilcla Giienee. 



This larva, which is commonly found in the stalks of the 

 potato and tomato, may be said to have a rather varied taste, 

 as it also bores into the stalks of the dahlia, aster, and cockle- 

 burr, the cob of the Indian corn, and the fruit of the straw- 

 berry. In Fig. 347 we have a representation of the larva. 



Fig. 347. Fig. :34S. 



When it leaves the fruit or other substance it has occupied, it 

 descends a little below the surface of the earth, and in a few 

 days changes to a brown chrysalis, from which the moth (Fig. 

 348) emerges from about the end of August to the middle of 

 September. 



In case this insect should so multiply as to require a 

 remedy, hand-picking is the only one suggested.
