The western bean Cutworm monitoring program needs the help of bean producers in the province

- Peak moth flight for WBC is expected this week or next week (2-3 weeks earlier this year)

- WBC moth numbers in Ontario traps are much higher than last year

- bean growers need to scout their earliest planted fields starting this week for WBC feeding damage on the pods. If they find significant damage, they need to spray the field with Matador asap.

Please refer to the links in Tracey Baute’s “Bugblog” below for specific information.

- all bean growers are encouraged to email or call 519-784-7110.

“We need fields to do small plot research on insecticide efficacy.”

Description: Potato leafhopper (PLH) adults (Figure 1) are pale green, winged insects about 3 mm long with piercing and sucking mouthparts. The adults are wedge-shaped, broadest at the head, with the body tapering evenly to the wing tips. There is a row of six rounded white spots behind the head. Eggs are 1 mm long, elongate and whitish. Wingless nymphs pass through five instar stages. In the first instar stage, the nymphs are about 1 mm long and are pale yellow in colour. By the fifth instar stage (Figure 5), nymphs have almost reached adult size and colour, but the wings are short, blunt nubs. Adults will readily jump or fly away if disturbed. Nymphs have the unique ability to easily move frontwards, backwards or sideways.
