Pheromone trapping began for western bean cutworm moths this week. Within just one day several cooperators were reporting catches. This is just the beginning of an extended moth emergence and flight, with their peak activity expected 2-3 weeks from now.
Take a gander at the “Armyworm Pheromone Trap Report.” The number of moths suddenly flying this week has us wondering where females will lay their eggs?
Locally, we found Japanese beetle adults on Monday, June 11, in field crops and flying around campus. This is certainly earlier than normal, as we typically think of them emerging more toward the end of June.
Grubs of the Asiatic garden beetle have been recently found damaging corn seedlings in northern Indiana counties.
Armyworm moth captures have varied throughout the state (see “Armyworm Pheromone Trap Report”). As I observed last week in Tippecanoe County, when larvae are small, their damage is negligible and easily overlooked.
Black cutworm pheromone trap cooperators have faithfully reported their week’s catches, but most haven’t been numerically challenged.
Pest managers should now be scouting their alfalfa for leaf feeding from weevil larvae. This pest is often overlooked during the early spring planting season.
Over the past few weeks armyworm moths have been captured in abundance in some of the traps placed at Purdue Ag Research Centers (see accompanying “Armyworm Pheromone Trap Report”).
Increasingly, slugs are becoming a topic of discussion with field crop producers. Not from the slugs’ disagreeable nature, but because damage to crops is becoming more apparent.
