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 14, 2023
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
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 24, 2023
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
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
Bollworm trap counts were steady or lower in every county this week, which indicates that we are past the peak emergence from the generation that developed in corn. However, there were still plenty of moths caught, so significant egg pressure
Heliothine Trap Counts, August 3, 2023
Bollworm pheromone trap catches for the week were down from last week’s catches in the Delta, but catches were still substantial, suggesting plenty of eggs are being laid in susceptible crops. Traps in Northeast Mississippi were fairly steady compared to
Heliothine Trap Counts, July 27, 2023
Bollworm pheromone trap counts were largely higher this week than last, with catches high enough to generate substantial bollworm pressure in susceptible fields. Tobacco budworm pressure was moderate in the Delta, but light in Northeast MS.
Heliothine Trap Counts, July 21, 2023
Corn earworm pheromone trap counts were average to above average for this time of year while tobacco budworm trap catches were about average overall for the week. With this number of moths flying, you should expect to have Heliothine eggs
Heliothine Trap Counts, June 8, 2023
As has been done for many years, pheromone traps for bollworm and tobacco budworm have been placed in numerous fields around Mississippi to give people an overview of the overall moth pressure from these two major pests. The data are
Heliothine Trap Catches, September 16, 2022
Pheromone trap catches of bollworm and tobacco budworm moths were down this week to more typical levels for this time of year. This is the last week that trap catches will be reported for this year. If you think that
Heliothine Pheromone Trap Catches, September 9, 2022
Bollworm moth trap catches rose this week and were very high for this time of year. While most crops are matured past the point where they are susceptible to bollworm feeding, any remaining late crops that are still susceptible could
Heliothine Trap Catches, September 2, 2022
Bollworm trap catches were down some in the Delta but stable in the Northeastern Hills region while tobacco budworm catches were similar to last week. Bollworm catches were still above long-term averages, so larval pressure should still be expected in
Heliothine Trap Catches, August 26, 2022
As expected, bollworm pheromone trap catches were up sharply this week in the Delta region to levels well above historical averages. However bollworm catches were similar to last week and to historical averages in the Hills region.
Heliothine Trap Catches, August 19, 2022
Bollworm moth pheromone trap catches were steady this week while tobacco budworm catches rose slightly. Both species were about average for this time of year. However, based on the high bollworm catches during late July and a lifecycle that takes
Heliothine Trap Catches, August 12, 2022
Bollworm catches were lower to steady this week compared to last week while tobacco budworm catches dropped to very low numbers. Bollworm catches are still above average for this time of year, so continuing pressure should be expected in vulnerable
Heliothine Trap Catches, August 5, 2022
After a record high catch reported last week, this week’s catch of both bollworm and tobacco budworm was lower, but still at or above average for this time of year. Therefore growers and consultants should continue to expect substantial bollworm
Heliothine Trap Catches, July 29, 2022
Bollworm pheromone trap catches were up again this week to record levels. Since 2008 (the first year I have easily available records), there has never been a week with a higher average bollworm moth catch than this week. The second
Heliothine Trap Counts, July 22, 2022
Bollworm and tobacco budworm pheromone trap catches were both up sharply this week in the MS Delta region and were somewhat higher in the NE Mississippi as well. Corn is no longer attractive to these moths, so expect to see
