INSECTS ATTACKING THE PEAR TREE. 



" Sucking Insects." 



I. * The Pear ' Leaf Blister Mite. Eriophyes pyri. Order 



Phytoptidae. 



This pest is found all over England now, and is on the increase. 



It has also been found out that trees near badly infested trees need 

 not be, and are not, themselves attacked. It is said to attack the apple 

 and several other rosaceous plants. It is easily recognized, as the 

 mite-infested pear leaves show raised patches or blisters with a minute 

 opening on the under side. These blisters are red or green, later 

 becoming brown. The mite is very minute, being about one hundred 

 and thirtieth of an inch long, having a rounded body and elongated 

 form. The anterior end of the thorax has a semicircular shield on 

 its upper surface. There are two pairs of five-jointed legs, each ending 

 in a claw with a four-plumed bristle. The abdomen is transversely 

 ringed. On the upper surface of the mite and springing from the hind 

 edge of the shield are two bristles. The abdomen bears two bristles 

 towards its front end, about the middle are two fairly long bristles, 

 • This is not a true insect.
