Winter Update (Oct 2, 2017; Wk 22) - 2017 Pea leaf weevil distribution map for SK

The 2017 Saskatchewan Pea leaf weevil distribution map was recently posted by Saskatchewan Agriculture.  The survey is based on the average number of feeding notches observed per plant (read more about PLW monitoring).  Watch for the November issue of Agriview when the 2017 map below will be posted accompanied by a written summary.  

Participants involved with the survey are thanked for their efforts and the extra sites that produced the 2017 pea leaf weevil map!  

The effort revealed a marked expansion in distribution within Saskatchewan in 2017 compared to 2016!

More information on pea leaf weevil can be accessed by reviewing Week 6 of the Weekly Update! 

Remember - a NEWLY UPDATED PPMN monitoring protocol is available!  Also refer to the pea leaf weevil page within the "Field Crop and Forage Pests and their Natural Enemies in Western Canada: Identification and management field guide" - both English-enhanced or French-enhanced versions are available.  A review of this insect was published in 2011 by Carcamo and Vankosky in Prairie Soils and Crops.
