Abstract
THIS publication includes a series of useful and interesting articles on injurious insects, by Profs. Howard, Marlatt, Felt and other well-known entomologists. Fortunately, injurious insects seem to have their day of destructiveness, and then cease to do much mischief; at least, for a time, owing to natural or artificial checks. Thus, respecting the much-dreaded San José Scale, Prof. Marlatt writes: “It is not especially feared to-day in California, and, in fact, it is looked upon by some of the largest fruit-growers (as I am informed by Prof. Washburn) as having been of positive advantage, the yearly treatment of trees having necessitated a system of regular short pruning, which has greatly improved the quality of the fruit, and much lessened the expense of gathering.” He, therefore, argues against undue alarm and excessive preventive measures respecting sudden and perhaps temporary insect attacks. Prof. Howard prints a translation from the Russian, by Dr. Fireman, of a paper by Porchinski, respecting the destruction of Tabanidæ by pouring kerosene into the pools to which they resort to drink. Other articles deal with caprification in California; the destruction of hairy caterpillars by birds; the progress of the never-ending campaign against the Gipsy Moth in Massachusetts, &c.
