The red-striped fireworm, Gele- chia trialbamaculella Cham., does some harm to blueberries at times. The larvae, which are pale green when small, develop reddish brown stripes along the back and sides as they grow older until they appear to have a solid color unless closely sxamined. These worms fasten two or more leaves and feed between them. They make a tubular case of silk covered with brown castings. The injury to the older leaves is light, but the stunting of new shoots resulting from the work of these worms on the terminal leaves is more harmful. A thorough appli- cation of the following spray about August 6, controls this pest: 40 '\ Nicotine Sulfate . 1 quart Fish-oil Soap ... .415 pounds Water 100 gallons White grubs, the larvae of June beetles, Phyllophaga sp., injure blueberry plants seriously by eating the fibrous roots. They are usually troublesome in the propagating bed in dry seasons unless excluded by a fine metal screen, coarse gravel, or cinders under the bed. Plants set on land recently in sod are very subject to attack. This can be pre- vented by keeping the land fallow for a year before planting. Mature bushes sometimes become infested. A solution of sodium cyanide, 6 ounces in 100 gallons of water, ap- plied around the crowns at the rate of 2 gallons per square foot, kills most of the grubs. The cyanide is a deadly poison, and must be used with
