Southwestern Corn Borer Monitoring – Week ending 7/13/2024
Bollworm pheromone trap counts rose slightly this week compared to the previous week. Tobacco budworm counts were higher in the Delta region, but absent in Northeast MS. Overall, heliothine insect pressure appears to be about average for this time of
Over the last 7 to 10 days, fall armyworm infestations in rice have increased a good bit. Currently pyrethroids are the only products labeled for fall armyworm management in rice. Since 2021 the performance of pyrethroids against fall armyworm has
Bollworm counts were stable to higher this week compared to last week, but much lower than last year at this time. The generation that developed on silking corn should be emerging, so expect bollworm moth counts to rise over the
Bollworm trap catches were stable to slightly lower this week compared to last week. The pressure from bollworms is much lower than last year’s record-breaking pressure. Tobacco budworms were barely present this week in all traps.
Bollworm trap counts were similar to last week overall, which is much lower than last year at this time. Tobacco budworm counts were fairly low this week.
Corn progresses through six stages as ears develop through reproductive growth stages. Identification of these stages can help time development, make prudent decisions and anticipate crop response to management practices and environmental conditions.
Bollworm pheromone trap counts were down sharply this week compared to last week in every county, so it appears we are in a lull between generations. Tobacco budworm we higher in the Delta, particularly in Leflore county. Actually only 1
With corn acres rapidly approaching tassel, southwestern corn borer traps are beginning to be deployed across the state. Limited data is available for this week but will become more abundant as the season progresses.
Below are the trap catches in pheromone traps for corn earworm (bollworm) and tobacco budworm. The numbers reported are the average trap catch in the county for the week. There are 3-4 traps for each species placed in each reported
Vegetative growth stages of corn are determined by counting the number of fully emerged leaves with leaf collars present. It is important to appreciate this methodology since it is a basis for timing many management practices, including herbicide application, sidedress fertilizer, and others.
The Feekes scale is likely the most commonly used system to describe wheat and other small grain’s growth and development stages. Understanding of wheat plant development is important so that you may better time management inputs to optimize crop response. This article helps you identify specific wheat growth stages.

Bollworm moth pheromone trap catches varied depending on the region of the state. While trap catches in all counties in the Northeastern part of the state were down to single digits this week, catches in the Delta region were up
Bollworm moth pheromone trap counts dropped some from last week to levels about average for this time of year. While overall insect pressure is not extremely high at this time, the number of fields that are attractive to bollworms are
Overall bollworm trap counts dropped slightly this week from last week, but this varied greatly by county with Lowndes county nearly tripling its counts while Sunflower county had less than 25% as many this week compared to last week. Compared
Bollworm moth pheromone trap counts were relatively stable from last week to this week, with catches rising in some counties and falling in others. Tobacco budworm catches remained low, with no moths caught in the Northeast MS counties this week
Bollworm moth pheromone trap counts rose modestly in most counties this week in both the Northeast and Delta regions. The moth catches in all counties were higher than the 10-year average, especially in the Delta region, so bollworm pressure in
