Heliothine Pheromone Trap Counts, June 23, 2017
With the exception of Washington County bollworm traps, counts were similar to last week at levels near or below historic averages for both bollworm and tobacco budworm. Therefore worm pressure in susceptible crops should be typical for this time of
Heliothine Trap Catches, June 16, 2017
Pheromone trap catches for bollworm moths were down for the week compared to the previous week. These numbers were also down somewhat from long term averages in both NE Mississippi and in the Delta. Tobacco budworm catches were low in
Moth Trap Counts for June 9, 2017
Pheromone traps are up and recording data in a number of counties around Mississippi again this year. We will try to report the counts weekly to help you maximize your efficiency in scouting crops for worms. Pheromone traps can’t replace
Insect Pheromone Trap Counts, August 10, 2016
Bollworm and tobacco budworm pheromone trap catches were overall similar to last week, and slightly above the long-term average trap catches for both pests at this time of year. This is the third consecutive week with strong numbers, so susceptible
Bollworm and Budworm Pheromone Trap Catches, August 3, 2016
Trap catches for bollworm remained high in some areas this week. Several traps caught more than 200 moths, while one trap in Washington County had 568 moths this week. Overall, moth catches were somewhat lower than they were last week,
Bollworm and Budworm Trap Counts, July 29, 2016
Bollworm moth trap catches were up sharply this week, especially in the Delta. Catches of both bollworm and tobacco budworm are currently well above historical averages in most regions, so you should expect high heliothine worm pressure in attractive crops
Pheromone Trap Counts and Assays, July 22, 2016
Pheromone trap catches for tobacco budworm this week were at higher levels than normally seen during this time of year in all areas of the state. Bollworms were back down some this week after being quite high in some regions
Heliothine Trap Catches, June 22, 2016
In the Delta, trap catches of corn earworm and tobacco budworm were similar to last week, which is lower than average for this time of year. However, in the Northeastern Hills, tobacco budworm catches were higher while bollworm catches were
Southwestern Corn Borer Trap Counts: June 18, 2016
Overall, southwestern corn borer traps remained low throughout the state. However, one trap in Leflore county captured 178 moths over a 7 day period. Although they do not appear to be widespread, this indicates that there may be pockets with
Pheromone Trap Counts, June 15, 2016
This week’s trap counts were similar to slightly higher than last week and last year for both bollworm and tobacco budworm. However, they are simlar to lower than long term average trap counts for this time of year. Corn is
Southwestern Corn Borer Trap Counts: June 11, 2016
All southwestern corn borer trapping locations did not report this week, but numbers were very low across the state. The highest numbers were in the south Delta, but still well below threshold with the highest number being 22 in one trap
Insect Trap Counts, June 8, 2016
Bollworm trap counts were somewhat lower this week in all counties except Lowndes. Tobacco budworm counts were slightly higher than last week, especially in the northeastern Hills region, but still not very high. Most corn is at or approaching pollination,
Pheromone Trap Counts, June 1, 2016
It is once again time to start posting pheromone trap results to assist you in making insect management decisions. This year we have 3-4 bollworm and 3-4 tobacco budworm pheromone traps in 5 Delta counties and 3 Northeastern Hill counties
2016 Insect Control Guide Now Available
The 2016 Insect Control Guide for Agronomic Crops is now available online. Hard copies will be available in January. Notable changes this year include the removal of pyrethroid insecticides for bollworm control in all crops due to resistance and poor
Pheromone Trap Counts, August 28. 2015
Bollworm trap catches remained similar to last week, which is somewhat lower than average for this time of year. Tobacco budworm trap catches were somewhat higher this week. As most crops are now beyond the vulnerable window for damage from
Pheromone Trap Counts, August 21, 2015
Bollworm moth trap catches were slightly higher in most counties this week but are generally lower than average counts for this time of year. Tobacco budworm moths continued to be caught at relatively low levels. Continue to monitor susceptible fields
Pheromone Trap Counts, August 14, 2015
Bollworm counts fell some for the second consecutive week, a clear indication that the generation that developed in corn has mostly emerged and we are now in the larval stage of the next generation. Tobacco budworm were similar to the
Terminating Spider Mite Sprays in Mid-South Cotton
There has always been a struggle with properly defining the correct cutoff for spider mites in cotton in the Mid-South region. For years we always loosely considered Node Above White Flower 5 (NAWF5 = Cutout) and 650 heat units the
Pheromone Trap Counts, August 7, 2015
Bollworm pheromone trap counts finally started to go down a little this week, likely signalling the end of the generation that passed through corn. However, enough moths were still caught to potentially cause economic losses in some areas. Tobacco budworm
Soybean Loopers and the Effect of Defoliation on Yield
We have been getting calls on loopers showing up in soybean for about 2 weeks. In recent days there have been reports of defoliation exceeding 20% or numbers exceeding threshold in some areas in the central to southern part of the state. The bulk of our soybean loopers typically show mid to late August or even into September so this is a little early but certainly not unusual. Soybean loopers are migratory and work their way north each year from southern latitudes. Early arrival could be due to a number of reasons.
Pheromone Trap Counts, July 31, 2015
Bollworm moth catches remained strong for another week as the generation that passed through corn continues to emerge. Continue to monitor for bollworms in all susceptible crops throughout the state. Tobacco budworm catches were a little higher in a few
Bean Leaf Beetles High in Delta Soybean Fields
Over the last week we have been getting a lot of calls about extremely high bean leaf beetle numbers. Most calls have come from the Northwest Delta region of the state. We have actually made bean leaf beetle targeted sprays on a number of acres in recent days. Yield loss is caused by defoliation and less frequently by pod feeding
Pheromone Trap Counts, July 24, 2015
Pheromone trap counts for bollworm were stable this week in the Delta while rising in the Northeastern region of Mississippi. Based on several weeks of fairly high bollworm moth catches, protection is likely needed in many fields against bollworm throughout the
Pheromone Trap Counts, July 17, 2015
After rising for several weeks, bollworm pheromone trap counts decreased some in the southern Delta region while slightly increasing in the hills and North Delta regions this week. This likely indicates that we are at peak moth flight for this
