Excerpt from Report of Observations of Injurious Insects and Common Farm Pests: During the Year 1898, With Methods of Prevention and Remedy During the past season there has been more than usual variety in the amount and also in the kinds of insect infestations. In a few instances these have been more than usually numerous, in some less observed than is ordinarily the case, a few species that are very rarely noticed were reported, and also one or two observations of extension of locality of somewhat serious infestations have been given. Amongst attacks that were unusually present, Aphides, or "Blight, " were especially named, and later in the year widespread loss was caused in many places to Cabbage growers, and also in private gardens, by the visitation of caterpillars of different species of Cabbage butterflies Pieris), which appeared almost in flocks, and set on foot little short of complete devastation. Amongst fruit attacks, that of the Pear Gnat Midge Diplosis pyrivora), causing destruction of the young forming Pears, was much more prevalent than in any year since 1883, when its presence was first recorded in this country. Amongst infestations which have been very little noticed previously is that of the Pith Moth Laverna atra), of which the maggot destroys entire bunches of Apple blossom-buds by tunnelling up the shoot immediately beneath the cluster. This attack has probably long been present, but not distinguished from another very similar in its effects, and it being brought forward may be certainly expected to enable orchard growers to get rid of it to a great extent. The Ground Beetles Pterostichus and other allied kinds, which have been so injurious for the last few years to Strawberry fruit, and for the ravages of which simple remedial measures have now been reported, see pp. 124-126)again appeared as a field crop pest to Mangold roots, also the Pigmy Mangold Beetle Atomaria linearis), an insect almost too small to be noticed excepting in the collections of hundreds or thousands in which it attacks the germinating or young Mangolds, again showed itself. Potato haulm has for some years been occasionally reported from various localities as being seriously injured by the tunnelling of a moth caterpillar for many inches up the stem, and from last seasons observations this appears to be the work of Hydroecia micacea, but two species may be present, and as one of these would be very easily kept in check, but not the other, more information is needed.
