Heliothine Trap Catches, September 6, 2019
Bollworm moth catches were lower in the Delta but higher in the Northeastern Hill region of the state this week compared to last week. Tobacco budworm catches were lower than last week’s peak, but still higher than during most of
Heliothine Trap Counts, August 30, 2019
Pheromone trap catches of tobacco budworm in Lowndes and Noxubee counties were the highest they have been all year and they were high in most traps in these counties, so it appears to have been a widespread flight. However, tobacco
Heliothine Trap Catches, August 23, 2019
Bollworm pheromone trap catches were down this week compared to last week. They were also low compared to long-term averages for this time of year.
Heliothine Trap Counts, August 16, 2019
Bollworm moth trap catches rose slightly in the Delta region this week and didn’t change in the Northeastern Hills region. Catches were about average for this time of year. Tobacco budworm catches remained low throughout the state.
Heliothine Trap Counts, August 9, 2019
Bollworm trap catches in the Delta appear to be between generations. Moth densities will likely begin to rise soon, so be alert for increased moth activity. Tobacco budworm catches remain low in all areas.
Heliothine Trap Counts, August 2, 2019
Bollworm pheromone trap counts held steady in the Northeastern Hills region of the state while dropping some in the Delta region. Tobacco budworm counts fell back into single digits after a 1-week spike. Expect to continue to see light to
Heliothine Trap Counts, July 26, 2019
Both bollworm and tobacco budworm trap catches are average to above average this week. Bollworm moths are beginning to emerge from early corn fields, so strong moth flights are expected to continue for awhile since corn was planted over a
Heliothine Trap Catches, July 12, 2019
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
Heliothine Trap Counts, July 5, 2019
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.
Heliothine Trap Counts, June 28, 2019
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
Heliothine Trap Catches, June 21, 2019
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
Heliothine Trap Counts, June 14, 2019
Bollworm moth trap catches changed little from last week and were similar to or lower than long term average catches for the week. Tobacco budworm moth catches were slightly higher this week than last week, but were still lower than
Heliothine Trap Counts, June 7, 2019
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
Heliothine Trap Counts, August 31, 2018
Bollworm moth trap counts rose slightly this week in most locations, with trap counts being comparable to long-term averages. Tobacco budworm trap counts remained low as they have been all year. As most agronomic crops are nearly past the stage
Heliothine Trap Counts, August 24, 2018
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.
Heliothine Trap Counts, August 17, 2018
Bollworm trap catches were stable to slightly higher across Mississippi this week compared to the previous week. Delta bollworm trap catches were lower this week than during the same week in 2017. Tobacco budworm trap catches remained low as they
Heliothine Trap Catches, August 10, 2018
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.
Heliothine Trap Catches, August 3, 2018
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
Heliothine Trap Catches, July 27, 2018
Bollworm pheromone trap catches were down a little this week in most counties. There are still plenty of moths available to lay enough eggs to cause economic damage in susceptible crops, so remain alert for bollworm infestations. Tobacco budworm pressure
Heliothine Trap Catches, July 13, 2018
Bollworm pheromone moth trap catches in our trap line surprisingly declined in the Delta region this week again, but increased slightly in Northeastern MS. However, one trap in Quitman county not normally reported here had 645 bollworm moths in it
Heliothine Trap Catches, July 6, 2018
Bollworm pheromone moth traps were relatively low for the second consecutive week. Tobacco budworm catches remained low as they have been all year. I expect bollworm catches to begin to rise next week as we will be about one month
Heliothine Trap Catches, June 29, 2018
Bollworm moth trap catches were lower this week in Mississippi. Tobacco budworm catches remained at very low levels.
Heliothine Trap Catches, June 22, 2018
Bollworm pheromone trap catches for the week remained relatively high in the Delta region, especially in Washington county. Tobacco budworm counts remain low in all counties. As corn matures past silk stage, fewer bollworm eggs will be laid in corn,
Heliothine Trap Counts, June 15, 2018
Bollworm trap catches are up sharply this week for the second consecutive week, especially in the Mississippi Delta region. Most of these moths will likely oviposit in silking corn where they cause minimal damage, but early cotton and soybeans should
