Insect Trap Counts, August 14, 2014

After 4 weeks of high bollworm moth catches averaging more than 75 moths/trap/week, this week has dropped down to an average catch of 35 moths/trap. This should mean that once current worm populations are controlled, a substantial reinfestation is not likely. However, tobacco budworm moth catches did not go down much this week, so late soybeans and non-Bt cotton could have mixed . . . → Read More: Insect Trap Counts, August 14, 2014

Insect Trap Counts, Aug. 1, 2014

Bollworm moth catches continued to be high across the state for the 3rd week in a row as the larvae that developed in corn continue to emerge. Expect significant bollworm larval pressure in vulnerable crops. Tobacco budworm moth catches rose in the Delta this week. Southwestern corn borer moth generation has now past and numbers are . . . → Read More: Insect Trap Counts, Aug. 1, 2014

Insect Trap Counts, July 25, 2014

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

Trap Counts, July 18, 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

Insect Trap Catches, July 3, 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

Trap Catches, June 27, 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

Trap Counts, June 20, 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

Caterpillars Infesting Mississippi Field Corn

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

Insect Trap Counts, June 13, 2014

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

Trap Counts, June 6, 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).
