Bollworm pheromone trap catches went down slightly in most counties, but rose sharply in Sunflower county, mostly due to a single trap which caught more than 400 moths during the week. Tobacco budworm catches were up in Noxubee and Washington

Bollworm moth trap counts rose in all counties except Noxubee, which was extremely high last week. Most corn is no longer attractive to bollworm moths, so these moths are likely to lay most of their eggs in cotton and soybean.

Bollworm and tobacco budworm moth catches in pheromone traps were very high in Noxubee County, but low to average in all other regions. I have been finding an unusually large number of yellow-striped armyworms in my pheromone traps the last

This week’s pheromone trap catches of adult bollworm moths were similar to last week, which are similar to historic levels in NE Mississippi, but much lower than typical in the MS Delta region. Tobacco budworm catches remained low except for 2

Pheromone traps in the Delta caught about twice as many bollworm moths this week compared to last week while bollworm trap counts in the Northeastern counties declined. Both regions were still lower than last year and long-term average catches. Tobacco

Bollworm pheromone trap catches were similar to lower than last week and tobacco budworm catches were few. For most crops, the threat of an economic bollworm infestation is likely past unless the field was planted very late.

Bollworm moth trap catches were down sharply this week, so hopefully that will translate to a break in bollworm larval pressure soon. Tobacco budworm trap catches remain at very low levels.

Bollworm pheromone trap catches were somewhat higher in Mississippi this week, especially in Coahoma county. Therefore expect bollworm egg and larval pressure to continue at similar levels for another week in susceptible crops. Tobacco budworm trap catches remain at very
