Show LURED BY A LIGHT. A Caelum Carbide Lamp Traps Vineyard Vine-yard Peata. For anveral yeara peat the vlueyarda In the Important wluo growing dls-trlct dls-trlct of llcaujolttla have suffered grtat-ly grtat-ly from the attucks of numerous (lying Insects, the moat important of which is known as the pyrulld. Last year, says tho Klcctricul ll. -view of louden, a series of experiments waa carried out In one of tho large vineyards to aee If the Insects could bo caught by bright lights burning at night. Aa apparatus was constructed, eonalatlut of an acetylene generator holding about six ounces of calcium carblda Ovor this waa 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 llxht at about ton candls power. This light the carbide was sufficient suf-ficient to keep burning for sis or eight hours. In a baaln a layer of water wot placed, and on top of this a layer of kerosene or some other cheap oil, of which about two fluid ounces were required. re-quired. These machines were set us about 650 yarda apart and were set In motion at dusk, preferably on dark nlghta. On ihe Drat night one lamp caught 4, KM) pyrallds and IIS moths of other kinds. During July the lamps averaged J, 200 luaecta per lamp psr night. The expenae of the lamps Is reported to have been two cenU per night each, or about two and a halt cents per night per acre. It la said that this method of catching noxlois Insects Is more efficacious than aay method which haa boon tried before. |
