Bollworm counts remain at fairly high levels again this week for the second week in a row, so vulnerable crops likely have many eggs and small larvae. Tobacco budworm counts remain low, so worms found will generally be bollworms. Southwestern corn borer trap counts were still fairly high in the most northern counties of the state, but . . . → Read More: Insect Trap Counts, July 25, 2014
Bollworm moth counts were up sharply across the state this week, so higher bollworm larval pressure should be expected over the next 1-2 weeks. Southwestern corn borer counts were high in Quitman, Tallahatchie and Leflore counties, but low elsewhere. Most corn is past the vulnerable window, so only late-planted corn that has not reached dough stage should . . . → Read More: Trap Counts, July 18, 2014
Bollworm catches were similar to the previous week while tobacco budworm counts continue to slowly rise. Neither is particularly high for this time of year. Southwestern corn borer counts were up sharply this week, with a few traps in the Delta above treatment thresholds for non-Bt corn. However, no county average was greater than 100 moths/trap, so . . . → Read More: Insect Trap Catches, July 3, 2014
Bollworm counts this week were similar to last week’s counts. Other than 1 trap in Sunflower County that caught 593 moths during the week, trap catches were all less than 100 moths/trap. Tobacco budworm catches inched higher for the second week in a row. Southwestern corn borer catches are still very low, suggesting that there is no . . . → Read More: Trap Catches, June 27, 2014
Bollworm trap catches were up in the Delta region this week to levels about normal for this time of year. Most bollworm eggs will be laid in corn at this time when many corn fields are at silk stage. University research has consistently failed to show any benefit from spraying for bollworms in field corn at this . . . → Read More: Trap Counts, June 20, 2014
There are several caterpillar pests that commonly infest field corn in Mississippi. These include corn earworm, fall armyworm, and southwestern corn borer. . . . → Read More: Caterpillars Infesting Mississippi Field Corn
Bollworm trap counts were higher in Lowndes county this week, but all other locations were similar to the previous week. Tobacco budworm catches remain at very low levels throughout the state. Southwestern corn borer counts were also very low throughout the state. Moth catches may have been somewhat depressed this week due to the frequent rains . . . → Read More: Insect Trap Counts, June 13, 2014
Bollworm catches were lower in the Delta this week but steady in Northeast MS. Tobacco budworm catches were negligible in all areas (Table 1). Southwestern corn borer counts were also low throughout the state, so early corn that is now tasseling will be unlikely to have significant issues with southwestern corn borer this year (Table 2).

Bollworm trap catches were down in the Delta region this week from last week, while tobacco budworm catches were higher in the Delta (Table 1). There was minimal change for catches of either species in Northeastern MS.
This is the first week to report southwestern corn borer pheromone trap results for 2014. Based on our new pheromone trap . . . → Read More: Pheromone Trap Counts, May 29, 2014
Bollworm trap catches were average this past week. While most traps caught 10-50 moths during the week, one trap near Indianola had 505 moths this past week. Tobacco budworm catches remain very low in both the Delta . . . → Read More: Pheromone Trap Counts, May 23, 2014
