Kaupp and published by [Sault Ste. Marie, Ont.] : Forest Pest Management Institute. This book was released on 1989 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two 20 ha plots located in the Gaspe region of Quebec were treated with spruce budworm, Choristoneura fumiferana (Clem.), nuclear polyhedrosis virus (NPV). Plot 1 received a single application of 1.15x10 12 polyhedral inclusion bodies (PIBs)/ha in a emitted volume of 4.5L/ha when second instar larvae were emerging from hibernacula. Plot 2 received two applications of NPV. The first treatment of 3.44 x 10 12 PIBs/ha was applied as second instar larvae were emerging from hibernacula; the second treatment of 2.3 X 10 12 PIBs/ha was applied 26 days later, when balsam fir buds had flushed and 94% on the larvae were in their third instar. Both treatments were applied in an emitted volume of 4.5L/ha. Assessment of the population reduction due to treatment and defoliation showed no significant differences (p=0.05) between the two treated plots and an untreated check plot. However, incidence of NPV infection, confirmed by microscopic diagnosis of smeared larvae, reached 22.9+-18.5% of larvae infected in plot 2, which was significantly higher than either plot 1 (10.3+-13,7%) or the check plot (6.9+-14.4%). Incidence of infection with the microsporidian parasite, Nosema fumiferanae, remained relative stable in all three areas with approximately 60% of the larvae infected. NPV infection in the check plot was attributed to a low level, persistent, naturally occurring virus. These dosages of NPV were unsuccessful in protecting foliage or achieving insect control by initiating an epizootic. Early application of NPV does not appear to be a viable control strategy. Even higher dosages of NPV may be required to initiate in spruce budworm populations.
