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.

Download or read book Viral Insecticides for Biological Control written by Karl Maramorosch and published by Elsevier. This book was released on 2012-12-02 with total page 823 pages. Available in PDF, EPUB and Kindle. Book excerpt: Viral Insecticides for Biological Control focuses on the basic as well as applied aspects of viral insecticides, which have the potential to significantly reduce the current reliance on chemical pesticide technology. This book serves as a guide for the development of means to identify hazardous problems and prevent them. Organized into six parts with a total of 23 chapters, this book describes the taxonomy, nomenclature, identification, physical, biological, as well as chemical characteristics, replication, and pathology of insect viruses. This reference material also explores the dispersal, stability, and utilization of insect viruses as biological control agents. The factors and considerations that must be taken into account when a viral insecticide is sought as a large-scale commercial alternative to other more traditional methods of pest control are also addressed. Because this reference material collates information in this field of interest, it will benefit a wide audience of readers, including researchers, students, and those working directly in crop protection.
