What is the spruce budworm?<\/h2>\n \n \n

The spruce budworm (SBW) is the most destructive insect of conifer stands in North America. In Quebec, the spruce budworm mainly consumes the annual foliage of the balsam fir, the white spruce and, to a lesser extent, the red spruce and black spruce.<\/p>\n<\/div>\n \n

The Bacillus thuringiensis<\/em> var. kurstaki (Btk<\/em> )<\/h2>\n \n \n

Btk<\/em> is a bacterium naturally present in soil, water and vegetation. This bacterium was isolated from the soil for use as a biological insecticide. Its insecticidal power comes from the fact that during its growth cycle, the bacterium produces spores and crystals that are, after ingestion, transformed into a toxin. This process only has an effect on insects of the lepidopteran family. A quantity in the order of 1.5 liters per hectare is sprayed on precisely targeted forests. Registered by Health Canada, Btk<\/em> Biological Insecticide is recognized worldwide for its safety towards non-target species.<\/p>\n<\/div>\n \n

What are the regions affected by the spruce budworm epidemic?<\/p>\n<\/span>\n \n +<\/span>\n

\n

The regions of Quebec currently affected by the epidemic are Bas-Saint-Laurent, Saguenay\u2013Lac-Saint-Jean, Capitale-Nationale, Abitibi-T\u00e9miscamingue, C\u00f4te-Nord, Gasp\u00e9sie\u2013\u00celes-de-la-Madeleine, Chaudi\u00e8re-Appalaches and Outaouais.<\/p>\n<\/div>\n <\/div>\n <\/div>\n\n \n

\n
\n

Which tree species are most vulnerable to the SBW?<\/p>\n<\/span>\n \n +<\/span>\n

\n

Balsam fir is the species most vulnerable to the SBW. Next comes the white spruce, red spruce and black spruce. The Norway spruce is also vulnerable to SBW, but this is less well documented. SBW larvae can also be found on other tree species, such as larches. Hardwoods and pines are not affected by this insect.<\/p>\n<\/div>\n <\/div>\n <\/div>\n\n \n

\n
\n

When do aerial sprays occur?<\/p>\n<\/span>\n \n +<\/span>\n

\n

Aerial spraying against the SBW epidemic occurs between late May and early July. The periods of operation, meaning the periods when spraying is carried out, are in the morning (between 4 a.m. and 9 a.m.) and in the evening (between 6 p.m. and 9:30 p.m.), every day (7 days a week) if the weather is favourable to spraying.<\/p>\n<\/div>\n <\/div>\n <\/div>\n\n \n

\n
\n

How long will the current epidemic last?<\/p>\n<\/span>\n \n +<\/span>\n

\n

On average, if we observe the evolution of previous epidemics, a SBW epidemic lasts from 15 to 20 years in the same area. On the other hand, aerial spraying lasts around 10 to 15 years in the same region.<\/p>\n<\/div>\n <\/div>\n <\/div>\n\n \n <\/div>\n\n
