TIVES. 



Angleworm or Earthworm. The common angleworm often do- 

 stroys greenhouse plants by its burrowing. It is some- 

 times annoying in gardens also.

 Aphides or Plant-Lice, and Bark-Lice. Minute insects of various 

 kinds, feeding upon the tender parts of many plants.

 sion. Hot water (about 125°). Coal-tar fumes. Potash. 

 Fish-oil soap. Tobacco-water, and fumes. Alcoholic and 

 water extracts of pyre thrum. Hughes' fir-tree oil, 

 Apple. Apple-Bucculatrix {Bucculatrix pomifoliella, Clemens). 

 — A minute yellow or green larva feeding upon the upper 

 surface of the leaves, causing the lower surface to turn 

 brown. The cocoons are white and slender and are laid side 

 by side upon the under sides of twigs, where they are 

 conspicuous in winter. 



Remedies. — Burn cocoons in winter or apply strong kero- 

 sene emulsion to them. Arsenites for the larvae in summer. 

 Apple-Curculio {Aiitlionomus quadriuibbus, Say). — A soft 

 white grub, about half an inch long, living in the fruit.

 fifth inch or less long, feeding upon leaves. 

 Remedy. — Arsenites. 

 Apple-Maggot {Trypeta pomonella, Walsh). — Maggot; infests 

 fall apples mostly, occasionally attacks winter fruit. It 

 tunnels apples through and through, causing the fruit to fall
