Weekly Update (June 22, 2016; Wk 08) - Bertha Armyworm

Bertha armyworm (Lepidoptera: Mamestra configurata) - Moths should have appeared in pheromone traps by now since all areas of arable prairie farmland are highlighted either yellow or orange in the map below.

Those monitoring BAW pheromone traps may want to compare trap “catches” to the following reference photo kindly shared by Saskatchewan Agriculture below:

Provincial staff coordinate BAW pheromone trapping across the prairies and summarize cumulative counts in report or map formats:

● Saskatchewanians.... Watch for future Insect Reports.  
● Manitobans..... Exceedingly low numbers of male moths were intercepted during the first week of monitoring (Insect and Disease Report posted June 15, 2016, prepared by J. Gavloski).  

● Albertans......  Refer to the live 2016 map reporting Bertha armyworm pheromone trap interceptions.  A copy of the map (retrieved June 22, 2016) is below for reference.
