Abstract

A spruce budmoth population reduction of 82%, as measured by moth emergence, was realized after a foliar spray in which Futura®, a commercial Bacillus thuringiensis Berliner (B.t.) formulation, was added to a suspension of Steinernema carpocapsae (Weiser). The nematode suspension, which took advantage of the wetting and spreading agents in the formulation, was applied to runoff at the rate of 9785 viable infective juvenile nematodes per litre. Mortality was attributed to the nematodes; B.t. was not available to the cryptic larvae. Soil drench treatments were encouraging, and suggested that applications of nematodes to the soil may be feasible.

Résumé

Une diminution de 82% d’une population de la tordeuse de l’épinette, évaluée par l’éclosion des tordeuses adultes, a été obtenu suivant pulvérisation du feuillage avec Futura®, une formulation commerciale de Bacillus thuringiensis Berliner (B.t.), ajoutée à une suspension de Steinernema carpocapsae (Weiser). La suspension de nématodes, qui a tiré l’avantage des agents de mouillage et de dispersement de la formulation, a été répandue à la fuite au taux de 9785 jeunes nématodes infectieux viables par litre. La mort a été attribuée aux nématodes; B.t. n’a pas été disponible aux larves cryptiques. Les traitements de trempage du sol ont été encourageants et ont laissé supposer que l’épandage des nématodes au sol pourrait être utilisable pour faire la lutte.
