G3 Four lined leaf bug (Poecilocapsus lineatus). Bugs about y^^ inch long, yellowish, with four black stripes^ frequent various plants and injure some considerably. A serious enemy of the currant. There is but one brood annually. The winter is passed in the egg, which hatches about the last of May, the insect being full-grown about the middle of June. The white eggs are deposited in slits made in the wood. Treatment: dust affected plants with ashes. Spray young with kerosene emulsion. Cut and burn tips of bushes containing eggs. GRASS INSECTS 64 Army worm (Leucania unipuncta). Brownish, white striped caterpillars about 2 inches long devouring grasses and allied plants occasionally ap- pear in immense numbers. There are two or three generations an- nually in this state, but it is very exceptional that this pest is as destructive as it was in 1896. The parent moth is brownish, with a small white spot on the fore wing. The eggs are laid by preference in tough stalks of rank herbage, such as grows along neglected ditches, etc. Treatment: exclude the pests by ditching, or kill with poisoned baits. Prevent their occurrence by clean culture. 65 Hessian fly ( C e c i d o - myia destructor). Dark- er, broad leaves with free stool- ing, followed by the infested patches turning yellow, are the usual indications of attack. Fig. 55 Hessian fly There are two broods annually,.
