INSECTS INJURIOUS TO CURRANT AND GOOSEBERRY 491 



where it is easily seen. The egg hatches in a few days into a 

 small white maggot, which burrows around the berry and then 

 feeds upon the seeds. The location of the larva may be seen, as 

 the infested currant soon shows a clouded appearance and finally 

 turns red and a black spot appears. The maggot becomes full 

 grown in about three weeks and then eats its way out of the berry, 

 which has usually fallen to the ground. The mature maggot 

 enters the soil for about an inch and there changes to the pupa, 

 from which the fly emerges the next spring. 



Control. As the maggots usually remain in the berries a few 

 days after they drop, all fallen berries should be frequently 

 picked up and destroyed. Poultry running among the bushes 

 will do this very effectually. Other methods will suggest them- 

 selves from the above life history, but none seems to have been 

 carefully tested.
