Southwestern Corn Borer Traps – July 31, 2021
Pheromone trap catches were similar to last week for both bollworm and tobacco budworm, which is near or below average for this time of year.
Bollworm pheromone trap catches were up sharply in the Delta region this week while the bollworm traps in Northeast MS were down slightly.
Bollworm and tobacco budworm moth trap pheromone catches increased this week at most locations. However, trap catches are still below normal for this time of year for both species.
Bollworm moth catches in pheromone traps were similar or lower than last week, and continue to be lower than long-term average catches. However isolated traps sometimes catch large numbers of moths, so while the overall state should not have a
Bollworm and tobacco budworm moth catches continued to be average to below average this week in all locations. However, as corn matures past the point where it is attractive to bollworms, more of these moths will begin laying their eggs
Bollworm moth catches were up slightly from last week in the Delta region but down in the Hills region. Overall, both bollworm and tobacco budworm moth catches were below average for the week.
Corn borer trap numbers were variable and fairly low throughout the state this week.
Bollworm and tobacco budworm moth catches were both up slightly during the last week at most locations. Densities are much lower than last year at this time. Compared to long-term averages, bollworm catches are low in the Delta region and
Pheromone trap catches for bollworm moths in Mississippi were steady to slightly higher this week while tobacco budworm trap catches remained low. Overall the trap catches were at or below historical averages for this time of year.
Whitney Crow and I have placed pheromone traps for bollworm (corn earworm) and tobacco budworm in several Mississippi counties again this year and I will be reporting the catches weekly throughout the rest of the growing season. Coahoma county only
Bollworm moth catches for this week remained about average while tobacco budworm moth catches were very low.
Average bollworm trap catches for the week were at or below average for this time of year, while tobacco budworm catches remained very low this week.
Average bollworm moths per trap for this week were similar to last week and a little low for this time of year. Tobacco budworm moth catches were 0 in all traps except for 1 trap in Noxubee County.
Bollworm moth catches in pheromone traps were down this week to levels about average for this time of year. Tobacco budworm moth catches were zero in nearly all traps, so all heliothine eggs should be assumed to be bollworm at
Bollworm moth trap catches were up this week compared to last week as expected. Moths are emerging from corn now and will be primarily laying their eggs in cotton and soybeans at this time, so be attentive in scouting these
Bollworm moth trap catches were generally down this week from last week and were fairly average for this time of year. Tobacco budworm catches continued to be low, also about average for this time of year. However, as corn is
After reporting the first week of catches in the “normal” range last week, bollworm traps were filled with a unusually large number of moths this week, especially in the Northeastern part of Mississippi. Tobacco budworm trap catches remained at average
After two months of bollworm trap catches running higher than normal, this week the catches are similar to long-term averages. Tobacco budworm catches were also about average for this time of year.
Trap counts for southwestern corn borer are highly variable this week. We did have two locations in Tate and Leflore Counties that exceeded the threshold this week. As a reminder, thresholds for southwestern corn borer suggest spraying non-Bt corn 7
