THE RASPBERRY-CANE MAGGOT, 



Pho bia sp. 

 Order Diptera ; famil}^ Anthomyiid^. 



20. — A raspberry shoot attacked by the raspberry- 

 cane maggot. Natural size. 



Recently a new insect pest has appeared in many raspberry 

 plantations in New York state. It attacks the new shoots in the 

 spring, and in one field sixty per cent of the new growth was 

 killed by the insect in 1895. We first learned of its ravages in our 

 state in May, 1895, when specimens were sent to theinsectary from 

 two localities in central New York, Spencer and Cortland. Rasp- 

 berry plantations in the vicinity of Ithaca, N. Y., were at once 

 examined with the result that in some cases one-third of the new 

 shoots were being killed by the pest ; it was also nearly as destruc- 

 tive at Ithaca in 1896. 



Raspberry growers should therefore at once familiarize them- 

 selves with the work of this new insect enemy, so as to be able to 

 intelligently combat it whenever it may appear in their planta- 

 tions.
