second, dusting part of the squashes with green arsenite (copper 

 arsenite), combined with spraying the cucumbers or melons with 

 Bordeaux mixture, 1-to-ll formula. For garden patches are 

 recommended: First, planting squashes on the margins of the 

 patch previous to planting the cucumbers or melons; second, dust- 

 ing part of the squashes with green arsenite, combined with the 

 use of covers over the plants. For fall treatment, either squashes 

 or beans should be planted on the cucumber or melon fields during 

 September, and as soon as the beetles are found feeding upon them, 

 dust the plants with green arsenite. 



Il^TEODUCTIOK 



Although the striped cucumber beetle has been described and 

 figured, and some remedies for it have been given by Mr. Lowe 

 in Bulletin ISTo. Y5 of this Station, results obtained from attempts 

 to control the pest on a large scale in the pickle-growing sections 

 of Long Island, during the past two years, warrant the publica- 

 tion of a separate bulletin. Furthermore, the economic import- 

 ance of this pest, not only in the market garden sections but 

 throughout the whole State, makes it advisable that farmers 

 should be kept posted as to the best up-to-date methods of con- 

 trolling its ravages, so that even frequent repetition of old meas- 

 ures is pardonable. In addition, some new facts regarding the 

 life, history and habits have been obtained, which progressive 

 farmers can use to advantage and thus avoid applying remedies at 

 random.
