Here is the latest update on where the trap catches are for western bean cutworm in the region based on trap site data entered into the Great Lakes and Maritimes Pest Monitoring Network. Peak flight for Ontario and most other states and provinces on the network (except Michigan) occurred during Week 11 (Aug 3-9) (see Fig. 1). Trap catches are…
Before I talked about the WBC trap data, I want to thank everyone who set up a trap this year and are entering their data into the network. Despite COVID-19, there are more than 1000 WBC traps in the system! That is a record and helps us figure out what the flight patterns are. Now for the trap results. We…

Some regions caught up…
OMAFRA Field Crop Team July 19, 2018 2345 Comments Off on OMAFRA Field Crop Report – Week of July 17, 2018Cereals Winter wheat harvest progress is around 7-10 days ahead of last year. Given the relatively dry summer, early reports of yield have been average to below average although crop quality has been respectable. Post-harvest weed management A significant amount of annual weed seeds can be produced and dispersed after wheat harvest if the ground is left fallow. In some…
Tracey Baute July 16, 2018 3737 Comments Off on Western Bean Cutworm Trap Catches So Far and Crop Staging and Spray TimingWestern bean cutworm trap counts this year have been very low so far. Although I would normally expect at least the far southwest to be reaching peak moth flight later this week, the traps are not indicating that yet. It might happen but there are not nearly the same number of moths flying around at this time compared to previous…

Tracey Baute May 1, 2018 2316 Comments Off on Resistance Prevention – Managing Western Bean Cutworm and Mycotoxins in CornAuthored by: Dr. Art Schaafsma and Dr. Jocelyn Smith, University of Guelph Ridgetown Campus and Tracey Baute, Ontario Ministry of Agriculture, Food and Rural Affairs As the planting season begins, it is important to consider how best to manage western bean cutworm (WBC) damage this year and reduce the risk of resistance development. Western bean cutworm has become a serious…
I’m seeing a lot of pics on Twitter of recent WBC moth catches in traps, which I think is great. The more people that are trapping, the more data we have to work with to determine when peak flight takes place and when scouting is required. But trap counts do not indicate if a spray is required in corn. There…

Tracey Baute August 6, 2015 2215 Comments Off on Western Bean Cutworm – Still Scout Corn and Now Dry Beans TooTrap counts are still quite high this week in Ontario which indicates that peak flight hasn’t plateaued yet. So there is likely still lots of egg laying happening. Moths will prefer to lay eggs in later planted corn that is still in pre to early tassel stages or will find dry bean fields nearby. Just because a trap is catching…
A few tweets, text messages and reports from our scouts have indicated that WBC egg masses are being found in corn this week. The next two to three weeks are key for scouting and managing WBC for the bulk of the corn crop. Though the typical hot spots (eg. Bothwell area) are more prone to significant populations, last year taught…
Author: Jen Bruggeman, Research Assistant, University of Guelph Ridgetown Campus Western Bean Cutworm traps have been up in Ontario for approximately 5 weeks, with nil to low catches being reported until now. Just this week we have started to see an increase in moth captures, due to our resident population starting to emerge from the soil and due to the…
Tracey Baute September 22, 2014 2425 Comments Off on Scout for Western Bean Cutworm and Ear Mould NowAuthor: Jocelyn Smith, University of Guelph Ridgetown Campus “Check your fields for WBC and ear rots now and consider harvesting early to stop mould growth. Adjust your combine to discard lightweight mouldy kernels and dry mouldy corn as soon as possible.” If you had trouble finding Western bean cutworm (WBC) egg masses when scouting back in late July and early…
Tracey Baute July 23, 2014 2188 Comments Off on Western Bean Cutworm Reaching Threshold in Some FieldsEither our own resident WBC populations did fine over the winter or the recent storm fronts brought in the bunch of moths from the US or a combination of the two. But reports are coming in that fields between Thamesville and Bothwell and near Rodney have reached threshold, well, sort of. What is messing up everyone’s ability to determine which…
