POPULAR FRUIT GROWING. 



berry leaf that it has drawn together by silken bands and of 

 which it is devouring the green surface. When abundant, this 

 insect may do very much damage. It changes to a small rust 

 colored moth with white markings on the wings at maturity. 

 It has at least two broods. It winters over in the pupa state 

 in the ground near the plants. 



Remedies. The larvae are not easily reached with any in- 

 secticide as they are protected by the folded leaf. The first 

 brood is rather difficult to destroy without injuring the fruit. 

 Since the second brood does not appear until July, they may be 

 destroyed by mowing off and burning the foliage of the plants 

 or by scattering straw and burning it. Where there are but a 

 few infected leaves, they should be crushed in the hand. A 

 few trials will show the best method of crushing the worm in- 

 side. Arsenical sprays are also used but 

 the insect is so well protected that this 

 remedy is seldom satisfactory. 



White Grub (Lachnosterna sp). This is 

 the common white grub found in sod land. 

 It is the larvae of the June beetle and is 

 sometimes exceedingly destructive, when 

 plants are set out on land that has recently 

 been in sod, by eating the roots of the new- 

 ly set plants. On land that has been culti- 

 vated for two years it is seldom trouble-

 bug. It may be avoided by not planting 

 on land that was the preceding year in sod. 

 Strawberry Weevil (AntJionomus signatus). This appears 

 as a small, blackish beetle with gray pubescence when the 

 strawberry flower buds are well developed and lays an egg in 

 each, afterward puncturing the flower stock below the bud, so 

 as to check development. The larva feeds upon the pollen in 

 the unopened bud, and changes to beetle stage in midsummer. 

 It also attacks a number of other flowers in the same way. Oc- 

 casionally it is very troublesome to the strawberry for a num- 

 ber of years; then its injury stops suddenly for no apparent rea- 

 son. Only staminate or pollen varieties are attacked.

 commonly as June
