Lots more WBC moths have been captured in Ontario in the last couple of weeks. We have been having some technical difficulties with our online trapping system and some participants are still not entering their trap data or site information. But from the data that we have been able to collect, I can say with confidence that we have accumulated at least 364 moths, as of early last week. To put this in perspective, this time last year we had only captured 4 moths in our traps. Moths have been captured from Essex county all the way into southern Quebec.
Michigan and Ohio are also breaking records. Michigan has accumulated at least 3771 moths and Ohio has captured 927 so far. Speaking with my NY colleague today, they have now caught moths as far east as Long Island New York.
What does this all mean?
Moth flight continues to increase. They are apt to still be attracted to corn to lay their eggs but will prefer those fields not in tassel yet. Scouting for egg masses in corn fields is advised. Dry beans in regions where most of the corn is already in tassel may also be at risk.
I will write a blog tomorrow and a CropPest article for this week to provide you with all information needed to scout and manage your corn and dry bean crops for western bean cutworm.
