second, dusting part of the squashes with green arsenite (copper 
arsenite), combined with spraying the cucumbers or melons with 
Bordeaux mixture, 1-to-11 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. 
INTRODUCTION. 
Although the striped cucumber beetle has been described and 
figured, and some remedies for it have been given by Mr. Lowe 
in Bulletin No. 75 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.
