Root Louse 151 



causes the familiar rolling upward of the leaflets. The 

 soft tissue of the leaf is eaten and what remains turns 

 reddish brown, giving the plant a burned appearance. 

 There are two broods, and the winter is passed in the pupal 

 condition. Spray the plants in August with an arsenical 

 spray at the time the second brood appears. On account 

 of the first brood of the insects pupating in the rolled 

 leaves, the foliage may be mowed off and burned, thereby 

 practically exterminating them from the plantation. 



Sawfly; Slug. The adult of this insect appears in spring 

 and deposits its eggs in the tissues of the stem or leaf. The 

 larvae hatch in a short time and gnaw holes in the leaf, 

 developing in the course of five or six weeks into pale 

 green worms about three-fourths of an inch long. The 

 larvae burrow slightly beneath the surface to pupate, 

 emerging later as flies. There are two broods in the 

 Southern states and one in the North. Spray the foliage 

 with lead arsenate before the plants bloom, and again after 

 the fruit has been harvested, if necessary. 



Strawberry Weevil. This beetle deposits its eggs in 

 the developing flower bud of a pollen-producing straw- 

 berry. The insect punctures a bud and turns and deposits 

 its eggs into the puncture, then shoves it down into the 

 bud with its beak. It then passes down the stem of the 

 developing flower, where it punctures the stem, shutting 

 off the supply of sap, and the bud shrivels and drops to the 

 ground. There the larva develops to maturity and emerges 

 as an adult beetle in about a month from the time the egg^ 

 was deposited. 



Spraying with arsenicals is recommended, although, 

 from the feeding habits of the beetle it will hardly get 

 enough poison to destroy it. Mulch the field with straw 

 and burn it as soon as the fruit is off. The least amount of 

 damage will come by planting, pistillate varieties, setting 

 four rows pistillate with one row of some variety of stam- 

 inate berry, capable of producing an abundance of pollen. 

 The weevil attacks only the staminate flowers, and lives on 

 the pollen cells.
