with black dots in ring-like patches. In Illinois it usually 

 makes its appearance about the first of July, but sometimes 

 not until late in August. 



INSECTS. 



There are two or three kinds of insects usually spoken 

 of as leaf rollers which prey upon the leaves of strawberry 

 plants and cause them to roll up. They are very destruct- 

 ive some seasons, especially in the commercial strawberry 

 fields of our state. The strawberry crown borer and white 

 grub, the latter being the larva of the May beetle, are also 

 quite destructive in strawberry fields which have been 

 planted more than a year or two. The crown borer works 

 its way into the crown of the plant in midsummer and the 

 white grub eats the roots. The wilting and dying of the 

 plant is an evidence of the work of these insects, and they 

 may be found by digging up the plant. 



While your currant and gooseberry bushes are in 

 flower you may be surprised some day to see that scarcely 

 a leaf is left on the bushes. Go out and examine them. 

 You will probably find hundreds of small green worms. 

 These are the larvse of the currant saw fly, a fly not very 

 unlike a common housefly, but rather more yellow. The 

 fly usually appears when the flrst leaves open and their 

 tiny white eggs are laid on the under side of the leaves. 

 In about ten days they hatch and the worms, at first a 

 whitish color, change to green and later are ornamented 

 with black spots. Many people allow these worms to eat 

 up their currant foliage year after year, until the bushes 

 are too much weakened to produce fruit in any quantity. 

 Among raspberry insects the cane borer probably causes 

 the most mischief. It is a small black beetle, very slim^ 

 and about one half inch long. It makes two girdles 

 around the tip of the cane in June and lays an egg be- 

 tween the two, just above the lower girdle. The larva, 

 when fully developed, is about an inch long, bores down
