806 EXPERIMENT STATION RECORD. 



of cattle lice, the spotted paiia or strawberry leaf beetle, and the cur- 

 laut and gooseberry fruit fly. Brief notes are given on the yellow 

 woolly bear {Spilosoma virginica) which is reported as attacking- rasp- 

 berry leaves, on the tapestry moth {Tinea t(q)etzeUa)^ and on the 

 cucumber flea-beetle {Crepidodera cucumeris), with directions for com- 

 bating their injuries. 



The author figures, describes, and suggests remedies for the follow- 

 ing 3 si^ecies of cattle lice: Short nosed ox louse {Hcematojnnns eurys- 

 ternus), the long nosed ox louse {H. vitnla), and the biting louse of 

 cattle {Trichodectes scalaris). Tlie use of various powders, unctions, 

 liquids, and fumes is recommended and methods of treatment are 

 described. 



The spotted paria or strawberry leaf beetle [Typophorus caneUus gil- 

 mpes) is reported as attacking raspberry buds, causing serious injury. 

 The life history and description of the insect, together with some cor- 

 respondence relating to its appearance and treatment, are given. The 

 use of arsenites, handpicking, and the destruction of all rubbish are 

 recommended as i)reventive and remedial measures. It would seem 

 from the correspondence that Paris green was not wholly successful in 

 destroying the pest. In this case emulsions or repellents should be 

 employed. 



The most important work of the year was a study of the life his- 

 tory of the currant or gooseberry fruit fly {Epoehra canadensis). The 

 author reviews some of the literature referring to this insect and 

 gives in considerable detail its history, life history, and the remedies 

 suggested. 



The general description is as follows : 



"Perfect insect, a 2-wiDged. fly about the size of a house fly. Pale yellow or 

 orange with greenish iridescent eyes and dark bauds across the wings. Found 

 about currant and gooseberry bushes during June in Maine. Stings the currants, 

 depositing an egg under the skin that hatches and develops into a small white mag- 

 got, causing the fruit to turn red and drop prematurely. The maggots when grown 

 leave the fallen or hanging fruit, enter the ground, change to a pupa state from 

 which the fly emerges the following June." 



The premature falling of the fruit in which the worms usually remain 

 for some time suggest the destruction of the former as a possible means 

 of greatly restricting the number of the insects; mulching about the 

 bushes will also aid in keeping the fly in check. Other means are sug- 

 gested of greater or less practicability. So far as known there are no 

 parasites to keep the pest in check.
