THE CODLIN MOTH.

REQUIRES ATTENTION THIS MONTH Considered from a general standpoint, says Mi'./U\ A. Boucher, endlin moth is possibly the orchard pest that requires the greatest amount of attention during January. The hatching of tho moth in small numbers conimen:es in the latter part of October and continues in increasing numbers-through-November and December, the percentage developing from tho grub to tho chrysalis and moth form depending on the weather conditions. Whatever development .nay 'have taken place prior- to January, it is now well recognised that about tho middle of tha month, in districts where the moth has r.ot' already been brought* well under control, a heavy flight will take place, and, unless tho necessary precautions have been taken, within a very brief period a considerable percentage of fruit will show signs of infection. In anticipation of this flight tho classes of fruit liable to infection by. tho pest should be carefully laid thoroughly sprayed. Spraying "about January 8 or 10 for tho control of the moth may be regarded by the careful apple or pear grower as one of the most important operations of tho season. It has, says Air. Boucher, been no uncommon thing for some commercial and many domestic growers, after spraying up to the end of December and finding few, if any, signs of infection to feel satisfied that further trouble would not occur during tho rest, of tho season. Serious infection by tlie January flight mentioned, has been noticed too late. The grower has then realised that the materia) and labout already expended have been largely wasted, and he has been left to regret tho loss of a high percentage of his crop. Moreover, unless prompt end careful measures have Ixien taken to' prevent the escape of considerable .numbers of grubs to their hibernating quarters, infection has been created for tho following season.
