The Currant Worm And Hop-louse

Theso pests having already caused troublo to our Michigan horticulturists, tbis comtnunication on the subject, to the Massachusetts Ploughman, may prove timfily, as it is from one competent to write : Tho Currant Worm at present kiiown to mo niay be divided into threo classes - 1. Thoso which make burrows in the stems and twigs, of which I know two kinds infesting the cultivated red curran ts. 2. ïhoso which cut ofF tho tips of the twigs, of which I know one kind. 3. Ihose which eat tho leaves, of which I know 6even kinds. You will therefore perceive tbe improprioty of speaking oí' the Currant Worm. Of tho latter soveu, however, only three do important iujury in this State. Of these three tho ono which I have most frequently mont on the currant bushes in my garden within the last two years is the Imported Gooseberry Saw-fly (Uematus VciUricosus). The larvas (false Caterpillar) of this is green with black spots, except souietimes toward the end ot' its life, when the black spots are lost, Ithas 14 belly legs in addition to the usual six jointed legs. The one which I consider next in importance is the American Currant Moth (Eüopia ribearia), thehirvec (caterpillar) of which is yellow with white and black spots, and has oaly four bolly legs in addition to tho six jointed legs. The Imported Gooseberry Saw-fly may be attacked in tho eggs or in the larva. From about tho middle to the latter part ot ittay, or soon alter the leaves of the cnrrant bushes aro put forth tho eggH can be found attached to tho under side of the ribs ot' the leaves. Tho leaves should be examined every day at thia season, and those whioh have oggs on thera ahould bo picked off and burncd. Soon after, if tho eggs havo not been destroyed, little holos will be made in th blade of the leaf by tho young larvro whioh can thus be discovored more easily nnd should be killed. If this is neglectec the leaves will be moro and inore dovoured, tho larvBD reniaining beneath them most of tho time in easy reaoh, If tho bushes are not considered worth their care, thoy should be cut down, so as not to servo as nurseries for the propagation of these and other pests. Thu farmer who neglects them should feel ashamed. Somo of the larva; should be enclosed in a box, and brod to tho winged state, that the farmer may learn to reoognize the parents, tho males and femalos looking much unlike. Tho winged insec ts are very sluggish, and can be captured without difficuity when they are seen. A second-brood beeins to appear bv the latterpart of June and through July.if the former brood lías not been dostroyed, and must be attacked in a similar way. I fcnow very little of the Hop-plant Louso {Ajihk humuli ) whioh is a recontly importod European insect, if I am not misinformed. Any particulars in regard to its history will bo duly credited to the farmer who will supply mo with them. It is stated that an efficaeious remedy is to char tho hop-poles overy year before using them. Boiling the hop-poles in water, or soaking them in oil or corrosivo sublimato, would bo as good as ehurring them.
