White Sugarcane Aphid Update and Impact on Midge Applications

Populations of the white sugarcane aphid are expanding and increasing across the state. We have confirmed the presence of white sugarcane aphid in grain sorghum in 7 counties in Mississippi (Fig 1) and there are likely more. The counties where white sugarcane aphids have been found include Bolivar, Washington, Humphreys, Quitman, Panola, Tunica and Oktibbeha. . . . → Read More: White Sugarcane Aphid Update and Impact on Midge Applications

Management of Kudzu Bugs in Mississippi Soybeans

kudzu bug nymphs

By now most folks have heard of Kudzu bugs. In fact, we have now confirmed them in 52 counties in Mississippi. Kudzu bugs, Megacopta cribraria, was first found in Georgia in 2009. Since that time it has spread rapidly across the southeast kudzu bug map 7_8and is now moving west in to Mid-southern states. It was first found in Mississippi in 2012 and now covers most of the state. . . . → Read More: Management of Kudzu Bugs in Mississippi Soybeans

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

Assessing Control of Tarnished Plant Bug in Prebloom Cotton

Tarnished plant bug numbers have actually started off at low to moderate levels this year in the Delta region but just in the last few days numbers seem to be picking up pretty good in a few locations and square retention is not optimal. I have mentioned on numerous occasions the inability to adequately access product . . . → Read More: Assessing Control of Tarnished Plant Bug in Prebloom Cotton

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

Armyworms in Rice, Again!

It appears that 2014 is going to be the year of the armyworm in rice. I have had numerous calls, texts, and Tweets about armyworms in rice over the last week. If you have not had them in your rice to this point, consider yourself very lucky. . . . → Read More: Armyworms in Rice, Again!

White Sugarcane Aphid: A Potentially Devastating Pest of Grain Sorghum

WSA_close up kerns

In 2013 a new aphid pest called the White Sugarcane Aphid, Melanaphis sacchari, was detected in grain sorghum in 38 counties in Texas, Louisiana, Oklahoma, and one county in Mississippi. This species has apparently been around for years but the hosts switch to grain sorghum appears to be new. This pest can be devastating to grain sorghum if populations reach high densities. In fact, some fields have seen 100% yield loss. Another major factor is this aphid is difficult to control with currently labeled products. . . . → Read More: White Sugarcane Aphid: A Potentially Devastating Pest of Grain Sorghum

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

Importance of Monitoring Square Retention in Young Cotton

Square retention is a critical component of early season plant bug management. I would strongly encourage you to take square retention counts along with your sweep net counts prior to bloom. Not only does this help in the decision making process of treating plant bugs, but it also helps you to get a better idea of how the products you are applying are working. Numbers alone can be deceiving when adults are steady moving into the field. When large numbers of adults are migrating into a field it is not uncommon to have as many or more plant bugs 4-5 days after a spray than you did before you sprayed and it still would not equate to a control failure. . . . → Read More: Importance of Monitoring Square Retention in Young Cotton

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
