Résumé

Double aerial spray of B.t . ( Bacillus thuringiensis ) is considered an efficient approach to limit the impact of spruce budworm, Choristoneura umiferana (Clem.). A study was conducted to better understand the behaviour and performance of spruce budworm larvae subjected to double exposure to B.t . and to determine whether B.t . ingestion could generate supernumerary instars. Results indicated that a sublethaly treated spruce budworm population was generally less resistant to a second application of B.t . than an untreated population of similar developmental stage. The second application increased lethal and sublethal effects by inducing higher mortality rate, a second but shorter feeding cessation period, an increase in larval development time, the reduction of pupal weight and an increase in developmental polymorphism rate.
