It appears that we are beginning to see the next generation of bollworm moths flying this week. Trap catches in most counties were higher this week than last week. Catches are still relatively light compared to long term averages, so
Pheromone trap catches for bollworm, tobacco budworm and southwestern corn borer were very low throughout the state this past week. However, bollworm catches were slightly higher than last week, so we may be seeing the first moths of the next
This is the first week this year I am reporting trap counts but we have had most traps out for at least 2-3 weeks. Overall trap catches have been average to light. This week, the trap catches for corn earworm
Over the last couple of weeks I have had numerous calls about caterpillar pest in young soybeans. Most of these have been concerning beans that are still in the vegetative stages (V2-V5). The species that are being found are bollworm, yellowstriped armyworm, green cloverworm, granulated cutworm, alfalfa caterpillar, cabbage looper, garden webworm, and yellowstriped armyworm.
Although every major field crop we grow in Mississippi is responsive to at planting insect protection; field corn is perhaps the most consistent. Why is this?
There has been a tremendous amount of scrutiny put on the neonicotinoid class of chemistry in recent years because of the potential link to declines in bee numbers. Researchers are working feverishly across the nation and the globe to determine the exact causes of bee decline. No doubt pesticides can and likely play a role to some degree, but there are many factors that also influence bee health such as habitat loss, Varroa mites, and diseases.
Bollworm pheromone catches were lower again for the second consecutive week, suggesting that once control is achieved for current larval populations, a major reinfestation is unlikely. Tobacco budworm catches were also lower this week.
This week’s bollworm trap catches were similar to slightly higher than last week, while tobacco budworm trap catches fell slightly for the week. The trap catches are typical for this time of year, so expect moderate worm pressure in all sensitive crops.
Bean leaf beetle numbers have been increasing steadily over the last couple weeks. 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
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
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
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
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
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
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
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
There are several caterpillar pests that commonly infest field corn in Mississippi. These include corn earworm, fall armyworm, and southwestern corn borer.
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
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
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
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 and NE Mississippi regions.
As can be seen in the table below, trap counts this week were average in the hills and low in the Delta. This is in contrast to reports of bollworm larvae being abundant. More traps have been deployed this week,
Our pheromone traps were monitored for the first time this week. Bollworm catches were high for this time of year with an average of 46 moths/trap caught in Noxubee county, 40 moths/trap in Lowndes county and 13 moths/trap in Oktibbeha county. Given
The results from the Second Annual Future of Ag Graduate Student Competition are included in this post.
Bollworm moth trap counts were lower at nearly every location this week compared to last week, indicating that bollworms are primarily in the larval stages at this time. Tobacco budworm trap counts were also low, so if a field is clean, new infestations
