"When, as usually happens, they occur in large numbers, the leaves are rapidly consumed, and whole rows of bushes have been entirely stripped in forty-eight hours. Hence the impor- tance of close watching and prompt attention in applying the remedies to destroy them. A single defoliation, while it does not kill the bushes, retards growth, and commonly greatly.

When the larvae attain full size, they burrow underground, or hide under scat- tered leaves, and spin an oval brown cocoon. After some weeks the perfect insect comes out and lays eggs, from which a second brood may appear in Southern localities. The win- ter is passed as larvae in their cocoons in the soil beneath the bushes. Fortunately this currant pest is easily destroyed by the ap- plication of poisons. White hellebore has been the standard remedy for many years. It is either dusted on to the bushes or a water mixture of it sprayed on. It is the only safe thing to use after the fruit is over half-grown. But extensive currant- growers now use a Paris-green spray (one pound to one hun- dred and fifty gallons of water) freely when the larvae first ap- pear, and often so effectually destroy the first brood that the insect is not a serious menace to the crop during the rest of the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - colora
