 figure. The larva pupates within the rolled leaf, 

 and about midsummer emerges as a moth. These 

 moths deposit eggs for a second brood of caterpillars 

 that feed upon the leaves late in summer, changing 

 ■to pupse early in autumn, and, passing the winter in 

 that condition, emerge again as moths the following 

 spring, thus completing the cycle of the year. In. 

 the Southern States there are three, and possibly 

 four, broods a year. 



Remedies. — The best way to destroy this pest is 

 to mow the field soon after the strawberry crop is 

 gathered, and after leaving it a day or two to become 

 dry, burn it over. This will destroy the leaf-rollers 

 as well as several other kinds of insects, and the 

 spores of fungous diseases. It is sometimes necessary 

 to scatter a little straw over the field where the leaves 

 are not thick enough to burn well. The plants will 

 not be damaged, but will soon send up a new lot of 

 leaves that will grow rapidly, and be free from insect 

 .and fungous attack. If for any reason this method
