Digging into Research
Lygus populations varied from year to year and by geographic location. More rainfall in the grey and moist black soil zones resulted in lower Lygus abundance. The Lygus genus is a diverse group with over 11,000 species, with four species being important pests on the Prairies:...
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...
Safflower and sunflower demonstrated potential as trap crops to reduce Lygus damage to faba beans. The Lygus pest complex in the Canadian Prairies is dominated by L. lineolaris, L. keltoni, L. elisus, and to a lesser extent, L. borealis. While Lygus have a broad host range,...
The overall Economic Injury Level was found to be around 9 to 23 Lygus bugs per 10 sweeps using $15.47/bu ($682/tonne) canola prices. However, insecticide trials on farmers’ commercial fields found that yield was protected from Lygus feeding with a foliar insecticide application at the...
Research in southern Alberta found that canola fields seeded in April were the most susceptible to cabbage seedpod weevil. A new action threshold of 25 to 40 cabbage seedpod weevils per 10 sweeps at early flowering stage was developed. When cabbage seedpod weevil populations were...
Lygus bug and chocolate spot disease can damage faba bean seed. Research found both organisms are widespread in central and southern Alberta. Seed damage occurs independently of each other, and is primarily caused by lygus bug. Seed damage caused by lygus bug (Lygus spp.) or chocolate...
