322 PESTS OF ORCHARD AND SMALL FRUITS 



lime-sulphur solution in early spring, just as the buds are starting, is 

 also an effectual treatment, resulting in killing the eggs. Use the mate- 

 rial at the same strength as for San Jose scale. 



Red Spider on Fruit Tree Foliage {Tetranychus bimaculatus Harvey) 



Another mite attacking the foliage of fruit trees, and sucking the 

 juices, is the common red spider so often troublesome in greenhouses. 

 It hibernates in the soil near the trees. When feeding on fruit tree 

 foliage, this mite usually is green in color. It has two dark spots on 

 the abdomen. It spins a very thin web on the under leaf surface, 

 and feeds beneath. This habit will readily distinguish it from the 

 clover mite just described. See page 207. 



Spraying with sulphur, 10 pounds to 50 gallons of water, is an 

 effective treatment. Add soap to make the sulphur mix with the 

 water, and keep the mixture well stirred. Screen the sulphur to 

 remove lumps before adding to the water. 



The Rose-chafer {Macrodactylus subspinosus Fab.) 



Hordes of long-legged, sprawling beetles attack the blossoms of 

 grapes, ripening fruit, such as cherries, and the blossoms of flowers.

The body of the beetle is a little over one third of an inch long, rather 

 slender and cyUndrical, and dull greenish or golden yellowish in color.
