Our newest bio-control of spotted knapweed, the blunt knapweed flower weevil, Larinus obtusus. This beetle will establish itself readily and spread quickly through your knapwee. We've seen noticeable declines in knapweed seed production and increased plant stress due to this new insect.
Pre-order your weevils now for July 2001 delivery!
$100/carton of 105 adult flower weevils.
Our second insect against spotted and diffuse knapweeds is the Lesser Flowerhead Weevil, Larinus minutus. This long-lived beetle lays its eggs throughout the summer on the flowers of both diffuse and spotted knapweeds. Like the other flower attacking agents, this species contributes greatly to reducing the production of new knapweed seed.
The Knapweed Flowerhead Weevil is winter cold hardy and yet thrives
in hot, dry summer knapweed environments. If you have spotted
or diffuse knapweed, you should get some of these beetles released
this year. Both the Blunt and Lesser knapweed weevils are compatible
in your knapwee infestations. Cartons of105 adults are $100.00.
