The incjuiries received regarding treatment come from all parts of the country. :\Liny growers say washing witli parattin of little use. Thrs is certainly true, as the ova of any one species I tiud hatch ver\- uueveidy, and the result is, many lice have damaged Inuls ami blossom and eurled leaves, whilst others are coming out, and thus a ceitaiii number escape the If we wash as soon as thev beuin to hatch it is no good unless we are prepared to go on evei'y dav for jierliaps sevi'i'al weeks, an impossilde process. <_»nly a penetrative wash will get into tlie lice pro- tected by curled leaves. After many experiments I eventually have come to the conclusion the most vulner- able time in the life-liistory of these plant lice is wdien in the sexual stage in the autumn. "When we find the small Vjiugiess or winged sexual fomrs under the leaves is tlie time to kill them. At this time a heavy paraffin emulsion may be used, as the leaves are of little value and it does not matter if we burn them. The Apple Aphides are then killed before they lay their eggs, and their future attack is guarded against. The emulsion must not be put on with much force, as the leaves may lie knocked off. The tree should have it good spraying, ami the ground below ^^â ell w"etted and also the trunk, the (.iviparous females will then lie killed. I am confident that untiiniiKiI sjjrai/ini/ for these pests is most essential. If it is more troublesome it does good, and the usual spra}'ing when ttie leaves are
