Research suggests canola flower midge are native species
Ontario is the only province to deal with two canola midge pests
Bt-resistant corn borer concern grows
Critical tools for controlling corn borer could be lost
Bt-resistant populations of European corn borer pose a significant risk to Canadian crop producers. With multiple resistance uncovered, it’s possible Bt-based control technologies will cease to work for the problem […] Read more
Insects posing problems in Saskatchewan crops
Grasshopper, flea beetle damage already reported
MarketsFarm – Although it’s still early in the growing season, some insect pests have already posed a threat to crops in Saskatchewan or could do so in the near future, […] Read more
Controlling insect pests without harming beneficial insect species
Science Notes: Horizontally transferred genes in insect genomes can selectively kill green peach aphids
Killing crop-damaging insects by targeting genes essential to their survival is a promising approach to pest control. Because essential genes are often conserved across multiple insect species, the challenge is […] Read more
Beneficial bugs protect stored grain
Biocontrols prevent bug infestations in processing and grain facilities
Glacier FarmMedia – Intentionally placing bugs in grain and food processing facilities to help manage pests is a tough idea to swallow in Canada, but the practice has been used […] Read more
Silage growers urged to protect feed supply from Bt-resistant corn rootworm
Pest has caused significant yield loss in both Canada and the U.S.
Some livestock producers in the U.S. corn belt have had to make a difficult and costly decision. They’ve harvested their silage corn for grain to salvage some financial return. Now […] Read more
Ontario confirms canola flower midge populations
New midge species could be native to North America
The emergence of a new canola gall midge in Ontario in 2021 has prompted researchers to re-assess swede midge data. The canola flower midge (CFM) was first noted in Western […] Read more
Local data useful for better crop management decisions
Engineering graduates develop technology that helps vineyards and orchards manage fungal and pest pressures
A Niagara-region start-up is offering field-specific, real-time weather data and spore collection to help farmers with smart fungicide scheduling for orchards and vineyards. Founded by three University of Waterloo mechatronics […] Read more
Pest management research in dry beans largely grower-led
White mould and western bean cutworm control among top priorities
Research results from the University of Guelph’s Ridgetown campus are equipping bean growers with new knowledge to make informed pest management decisions. Chris Gillard, associate professor in the department of […] Read more
National group launches standardized corn borer scouting protocol
Goal is to address lack of knowledge about ECB in non-corn hosts
A nationwide entomologist working group is promoting a new online scouting tool for farmers, crop advisors and researchers with the aim to broaden knowledge about European corn borer (ECB) damage […] Read more
