BLUEBERRY CULTURE 



15 



The red-striped fireworm, Gelechia trialbaniac-ideUa Cham., does some harm 

 to blueberries at times. The lar^•ae, 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 examined. These worms fasten two or more 

 leaves together and feed between them (Fig. 9). They make a tubular case of 

 silk covered with brown castings. The injury to the older leaves is slight, but the 

 stunting of new shoots resulting from the work of these worms on the terminal 

 leaves is more harmful. A thorough application of the following spray about 

 August 6, controls this pest: 



40 percent Nicotine Sulfate 1 cjuart 



Fish-oil Soap 4-5 pounds 



Water 100 gallons

 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
