 ■Leaf-Notcher (Artipr^ Floridmius, Horn). — Beetle, one-fourth 

 inch long, greenish blue or copper-colored, eating the edges 

 of the leaves. 

 Remedy. — Jarring. 

 Mite {Tetranychus 6-maculatus) . 



Remedies.— Kerosene emulsion. Sulphur. Practice clean 

 culture. 

 Scale. — Many species, preying upon the leaves and shoots. 

 Remedies. — Kerosene emulsion applied with a brush or in 

 spray, just before the trees bloom, and at intervals of two 

 or three weeks as occasion may require. Lye wash. Lye- 

 and-sulphur wash. Pyrethrum decoction. Resin and fish- 

 oil soap. When young the scale is more easily destroyed. 

 Parsley. Parsley- Worm (Papilio Asterias, Cramer). — Larva, 

 inch and a half long, light yellow or greenish yellow with 

 lines and spots ; feeding upon leaves of parsley, celery, car- 

 rot, etc. When the worm is disturbed, it ejects two yellow 

 horns with an offensive odor, from the anterior end. 



Remedies.— Hand-picking. Poultry are said to eat them 

 sometimes. 

 Parsnip. Parsley-Worm.— See under Parsley. 

 Parsnip Web- Worm {Depressaria heracliana, De Geer) . — Larva, 

 about a half inch long, feeding in the flower-cluster and caus- 

 ing it to become contorted. 



Remedies. — Arsenites, applied as soon as the young worms 

 appear, and before the cluster becomes distorted. The 

 worms are easily disturbed, and hand-picking is often ad- 

 visable. Burn the distorted umbels. 

 Pea. Pea- Weevil or Pea-Bug {Bruchus pisi, Linn.).— A small 

 brown-black beetle, living in peas over winter. The beetle 

 escapes in fall a«kd spring and lays its eggs in young pea- 

 pods, and the grubs live in the growing peas. 



Preventive. — It is said that coal-ashes or sand saturated 

 with phenyl and sown with the peas will prevent attack. 



Remedies. — As soon as the mature peas are picked, and 

 while the grubs are only partly grown, subject the peas to 

 a temperature of 14.5° for an hour. The seed will not be 

 injured. The ripe peas may also be confined in some tight 

 receptacle, and a little bisulphide of carbon added.
