Although sugarbeet root maggot (SBRM) fly activity is currently at low levels throughout most of the Red River Valley (RRV), all indicators thus far suggest that some sites within the Valley will experience very high populations this year.
The first sugarbeet root maggot (SBRM) flies of the season were observed on Tuesday, May 26 in a field near St. Thomas, ND.
This week’s featured is the green lacewing (Chrysopa species). The adult is a beautiful 1 inch long, green insect with 2 pair of clear, network-like wings, and large golden to red eyes.
Insect pest updates on canola, alfalfa, wheat, and field peas.
This week’s featured group is beneficial wasps (also called parasitoids) that attack and kill eggs and immature stages of many insect pests. Parasitoids are described as tiny wasps in the insect order Hymenoptera and include many different families (Braconidae and Ichneumonidae, for example).
Since the cold temperatures have slowed insect pest activity this past week, I thought this would be a good opportunity to update you on the status of a few invasive insect pests of field crops. Please look for these invasive insect pests when you are out scouting fields or around your home.
Aster leafhoppers and other species of leafhoppers were observed in large numbers in a winter wheat field near Aneta in Nelson County (source: Huso Crop Consulting).
This week’s feature is spiders; which are closely related to insects, but in the Class Arachnida.
Early season cutworms are starting to show up in fields.
We will be running a “good” bug section in the newsletter this year to increase knowledge and identification of good or beneficial insects.
This table summarizes the transgenic traits that are available in corn for insect and weed management. Dr. Chris DiFonzo, Field Crops Entomologist, of Michigan State University updates the table each year.
