Several species of Aphids infest pines, including Lachnus pini- 

 radiatae, Davids., and Essigella calif ornica, Essig. The former is a 

 sedentary species, often remaining in one position for weeks at a 

 time. The attacked leaves become covered with a gray, waxj 

 secretion and eventually a coating of black, sooty mould, which 

 grows on the honey-dew secreted by the Aphids. E. californica is 

 an active species which feeds for a day or two in one place and retreats 

 to a protected position if disturbed or in wet, windy weather. Though 

 the damage it does is inconspicuous, it is probably more important 

 than all the above species together.

 to Florida as an experiment for the control of Dialeurodes citri, which 

 is the worst insect pest of citrus fruit in that state. In the three
