Economic losses due to insect pests is estimated at over $204 million in an ‘average’ year. Every year, insect pests cause substantial economic losses on the Prairies. Yet there is no estimate of the total economic cost from insect damage. A review was conducted to develop...
Mechanical wounds on canola cotyledons, simulating flea beetle feeding, allowed infection of the blackleg pathogen while no infection occurred on un-injured cotyledons. Wounds that were 8 hours or older before inoculation had lower levels of infection. Temperature, leaf wetness and relative humidity also played a...
This study validated the nominal economic threshold of 25 per cent defoliation. It also determined significant associations between landscape structure and flea beetle abundance, weather and flea beetle abundance, and plant density and flea beetle damage. As well, two flea beetle predators were confirmed. Flea beetles...
