Time of Day Sampling and Stink Bugs
This is some old data from 2007 but it is still relevant today. How does time of day effect stink bug populations? When this small test was conducted we did not have redbanded stink bugs in our system but I
Heliothine Trap Catches, August 27, 2020
Bollworm moth catches for this week remained about average while tobacco budworm moth catches were very low.
Identifying Late Season Soybean Growth Stages
As we move closer to maturity, there are many decisions to be made on termination timing of various management practices. At this time of the season, we can use late season soybean growth stages as a guide to decide when
Heliothine Trap Catches, August 20, 2020
Average bollworm trap catches for the week were at or below average for this time of year, while tobacco budworm catches remained very low this week.
Heliothine Trap Catches, August 13, 2020
Average bollworm moths per trap for this week were similar to last week and a little low for this time of year. Tobacco budworm moth catches were 0 in all traps except for 1 trap in Noxubee County.
Southwestern Corn Borer Traps, August 8, 2020
Although most corn across the state is beyond the susceptible stage, southwestern corn borer traps were very high in some counties with multiple traps exceeding 100 moths per trap.
Heliothine Trap Catches, August 6, 2020
Bollworm moth catches in pheromone traps were down this week to levels about average for this time of year. Tobacco budworm moth catches were zero in nearly all traps, so all heliothine eggs should be assumed to be bollworm at
Southwestern Corn Borer Traps, August 1, 2020
Southwestern corn borer trap counts increased again this week in several counties. Traps in Leflore, Carroll, and Tate counties exceeded the current threshold of 100 per trap. As a reminder, corn is considered safe from yield losses from southwestern corn
Heliothine Trap Catches, July 30, 2020
Bollworm moth trap catches were up this week compared to last week as expected. Moths are emerging from corn now and will be primarily laying their eggs in cotton and soybeans at this time, so be attentive in scouting these
Southwestern Corn Borer Traps – July 25, 2020
Overall, southwestern corn borer trap numbers are beginning to decline. Only one location in Leflore county exceeded the threshold of 100 per trap this week.
The Use of Biological Insecticides for Bollworm Management in Soybean
There are several biological insecticide options labelled in soybean; however, the most readily available and widely used product is Heligen. In the last week, many people have asked about the use of Heligen with the low bollworm numbers showing up
Heliothine Trap Catches, July 23, 2020
Bollworm moth trap catches were generally down this week from last week and were fairly average for this time of year. Tobacco budworm catches continued to be low, also about average for this time of year. However, as corn is
2020 Bollworm Management in Cotton and Soybean
This last week there have been reports of bollworm eggs starting to show up in Mississippi Cotton. Generally speaking, in a normal year the bollworm flight would begin around July 4th, and peak around the 15th. The wet spring pushed
Heliothine Trap Counts, July 17, 2020
After reporting the first week of catches in the “normal” range last week, bollworm traps were filled with a unusually large number of moths this week, especially in the Northeastern part of Mississippi. Tobacco budworm trap catches remained at average
Preparing for the Bollworm Flight Podcast
http://extension.msstate.edu/mississippi-crop-situation/audio/2020/prepare-for-the-bollworm-flight Bobby sits down with the entomology team (Angus, Jeff, Don, and Whitney)to discuss the impending bollworm flight, what to look for and how to move forward.
Southwestern Corn Borer Traps, July 11, 2020
Trap count continue to increase in many regions of the state, but few are at threshold. As a note, the 2 traps that captured high numbers of moths in Tate county last week were knocked down this week and are
Heliothine Trap Catches, July 9, 2020
After two months of bollworm trap catches running higher than normal, this week the catches are similar to long-term averages. Tobacco budworm catches were also about average for this time of year.
Rainfall and Insecticide Efficacy
With the increase of rain showers this week and tarnished plant bug numbers starting to pick up in some places, now is a good time to revisit the impact of rainfall on insecticide performance. Rainfastness is a complex topic because
Southwestern Corn Borer Traps, July 4, 2020
Trap counts for southwestern corn borer are highly variable this week. We did have two locations in Tate and Leflore Counties that exceeded the threshold this week. As a reminder, thresholds for southwestern corn borer suggest spraying non-Bt corn 7
Heliothine Trap Counts, July 2, 2020
Bollworm pheromone trap catches were higher than long-term averages again this week as they have been all year, while tobacco budworm catches were about the same as long-term averages. As most corn is advancing past the green silk stage, more
Heliothine Moth Trap Catches, June 25, 2020
Bollworm pheromone trap catches were not extremely high this week, but June overall set a new high average trap catch and it the high catches were distributed among most monitored counties. To give some perspective, the highest previous years of
Heliothine Trap Catches, June 19, 2020
Bollworm pheromone moth trap catches have continued to be very high again this week in nearly all traps across the state. Tobacco budworm trap catches were also high in a few traps, suggesting that worm pressure from both species could
