bores downward through the pith. There is but one brood a year 

 of this insect. Pruning and burning the infested canes in au- 

 tumn seems to be the only way to fight it. 



TJie four-lined leaf hug, or yellow lined currant bug, sometimes 

 attacks gooseberries, though more frequently it is found on cur- 

 rants. It infests the leaves of the new growth. Slingerland ad- 

 vocates* the pruning and burning of the tips of infested shoots 

 in autumn, jarring the insects into a dish of kerosene and water 

 and spraying the young red nymj)hs as soon as they appear in 

 spring using kerosene emulsion diluted with five parts of water. 



The Sam, Jose scale does much injury when its gets established 

 on gooseberries. It has been found on the gooseberry in a few 

 localities on Long Island, and it should be especially watched for 

 in that section of the state and adjacent territory. For an ac- 

 count of its habits and best methods of fighting it the reader is 

 referred to Bulletin 87 of this Station. 



The goosebeni'ry fruit fly, also called the currant fly (Epochra 

 Canadensis, Loew.) causes considerable injury to the fruit of cur- 

 rants and gooseberries in some sections of the country. Accord- 

 ing to Harvey t the adult is a two-winged fly about the size of a 

 house fly, pale yellow with dark bands across the wings as shown 

 in Fig. 5. The fly appears in June and slings the fruit depositing 

 an egg under the skin. This hatches into a small white maggot. 

 Fig. 6, which feeds on the seeds and causes the fruit to turn red 

 and drop prematurely. When the maggot is full grown it enters 

 the ground, pupates and the following June emerges as a fly. 



Speaking of their attacks on currants Ilarvey says:}: a radical 

 remedy would be to pick the entire crop while green and before 

 the flies appear. Since gooseberries are frequently marketed 

 green this would seem to be the best method of fighting this 

 insect whenever it attacks that fruit. 



We are indebted to Dr. Lintner for the information that this 

 insect was noticed in Camden, N. Y., in 1893, and for several 

 years previous. Up to the present time it has attracted little 

 attention in this state.
