PEACH INSECTS 287 



The Striped PiJach Worm 

 Gelechia confuseUa (Jhaml^ers 



111 restricted localities in Michigan peaches are sometimes 

 attacked by small, dirty, yellowish-white caterpillars marked on 

 the back and sides by six longitudinal, reddish -brown stripes ; 

 when full-grown they are about | inch in length. They appear 

 in July and again in September and feed upon the leaves, which 

 they web together into loose nests. When full-grown, they 

 transform to pupae within the nest. The winter is passed in 

 the pupal state. The moth has an expanse of about f inch ; 

 the front wings are almost })lack with a purplish gloss ; the hind 

 wings are cinereous. 



When only a few trees are infested, it will pay to cut out and 

 burn the nests. In larger orchards the first-brood caterpillars 

 can be destroyed when they first appear by spraying with arse- 

 nate of lead, 4 pounds to 100 gallons of water, to which 4 pounds 

 of lime should be added to prevent burning of the foliage.
