Here is the first Heliothine trap catch report for 2025. We will strive to report our pheromone trap catches here weekly throughout the growing season. Each county reported is the average weekly catch per trap from 3-4 traps. The traps

Heliothine Trap Counts, July 12, 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
Heliothine Trap Counts, July 3, 2024
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 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.
Heliothine Trap Counts, June 12, 2024
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
Heliothine Trap Counts, May 22, 2024
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

Heliothine Trap Counts, September 7, 2023
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
Heliothine Trap Counts, August 31, 2023
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

Heliothine Trap Counts, August 17, 2023
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
Heliothine Trap Counts, August 11, 2023
