For several years past the vineyards in the important wine-growing district of Beaujolais have suffered greatly from the attacks of numerous flying insects, the most important of which is known as the pyralid. Last year a series of experiments was carried out in one of the large vineyards, to see if the insects could be caught by bright lights burning at night. An apparatus was constructed, consisting of an acetylene generator holding about six ounces of calcium carbide. Over this was a circular metal dish about twenty inches in diameter, and over this at a height of about eight inches a single acetylene jet giving a small, bright light at about ten candle-power. This light the carbide was sufficient to keep burning for six or eight hours. In a basin a layer of water was placed, and on top of this a layer of kerosene or some other cheap oil, of which about two fluid ounces were required. These machines were set up about 550 yards apart, and were set in action at dusk, preferably on dark nights. On the first night one lamp caught 4,600 pyralids and 218 moths of other kinds. During July the lamps avoipged 3,200 insects per lamp per night. The expei se of the lamps is reported to have been two cents per night each, or about two and one-half cents per night per acre. It is said that this method of catching noxious insects is more efficacious than any method which has been tried before.- Electrical Review.
