Trapping 50+ moths…in just 3 days… and it’s only May…is…concerning! <\/figcaption><\/figure><\/div>\n\n\n\n

Peridroma saucia<\/em> is common in Oregon. But for the past three years, we are detecting them at much higher-than-normal<\/strong> levels in early spring.<\/p>\n\n\n\n

The graph below<\/strong> shows pheromone trap counts (# of adult moths per day) in recent years vs. a long term average. Please note that all data points before May 10th are NOT regional averages. They represent only the Corvallis location. These 5 single-location data points are filled with a dot pattern (hard to see, sorry). However, in 2020, the true regional average (peach diamonds) remained higher than normal until June 1st.<\/p>\n\n\n\n\n\n\n\n

What does this mean? <\/h2>\n\n\n\n

Well, this species is known to overwinter (mostly as larvae > pupae > adults) in Oregon. Since there are 2+ overlapping generations<\/strong>, this first peak could mean a higher abundance throughout the season. <\/em><\/p>\n\n\n\n

Variegated cutworm larvae feed on many hosts<\/strong>. They are well known as a pest of peppermint but feeding has been documented on tomatoes, beets, alfalfa, grapes, ornamentals, and various vegetables. Scout now for eggs<\/strong> – they are laid in clusters on various landscape plants, weeds, even twigs and fence posts! If temperatures remain suitable, larvae could be evident by mid-May<\/strong>. <\/p>\n\n\n\n

NOTE: <\/em>It’s kind of odd\/cool that this is the first species to report on this year, because my new boss, Len Coop, did his dissertation<\/a> on variegated cutworm 35 years ago and it is still one of the best resources around! Thanks, Dr. Coop! <\/p>\n\n\n\n
