Larvae of diamondback moth infesting canola were found in canola located in southwest of Roseglen, McLean County, north central ND.
Sugarbeet root maggot (SBRM) fly activity is being monitored this year at 40 Red River Valley (RRV) sites by NDSU staff in cooperation with American Crystal Sugar Company and the MinnDak Farmers Cooperative.
Scouting for wheat midge is critical from heading through early flowering (<50% flowered), especially in areas where the 2013 fall soil survey indicated moderate to high risk for wheat midge larvae.
Corresponding with the relatively slow start to the 2014 growing season, sugarbeet root maggot (SBRM) fly emergence is also off to a slow start.
Scouting is crucial now when field crops are in early development stages. So, scout regularly for alfalfa weevil, cutworms, and grasshoppers
Flea beetles have emerged in large numbers with the warm, sunny days. Significant feeding injury (>50% defoliation) and stand loss are being observed in Bottineau, Rolette, Towner, Cavalier, Ramsey, Walsh, and Dunn Counties, especially on the early-seeded canola (before mid-May).
Several calls have come in about these giant mosquito-like insects.
Due to the recent hot weather, adult alfalfa weevils are emerging and have been observed in the southern regions and north central regions of North Dakota (sources: V. Chapara, NCREC).
Alfalfa weevil was a major pest problem in forages last year, especially in the southwest and south-central regions of North Dakota.
Most of the bare / turf soil temperatures are still below 50 degrees F for most of North Dakota.
With warmer spring weather, tick season is upon us.
