Cotton Insect Update: July 10, 2015
Tarnished plant bug populations have continued to be high over the last couple weeks in the Delta. A lot of the cotton is at or near the bloom stage when it is most attractive to plant bugs.

Bollworm trap numbers in the Delta and Hill regions have continued to increase some over what was reported last week. Southwestern corn borer numbers are still very high in some areas of the Delta and sprays may be needed in
Stink bugs consisted of Brown, Green, and Southern Green stink bugs, with Green and Southern Green Stink bugs making up 95% of the total stink bugs caught. Egg masses of both Kudzu Bugs and Stink Bugs have been seen in both regions in R3 and later soybean.
We are now beginning to get numerous calls from around the state about sugarcane aphid infestations. Populations range from very low to well above threshold with treatments becoming more common this week. At this time aphids are being found in the Hills and
Stink bugs consisted of Brown, Green, and Southern Green stink bugs, with Green and Southern Green Stink bugs making up 85% of the total stink bugs caught. Some small corn earworm larvae were found in very low numbers in the Delta region.
The biggest change for this week is the rise in southwestern corn borer trap counts. High numbers were spotty in the Delta with one Leflore county trap recording 668 moths in a week. Coahoma, Quitman and Sunflower counties were the

Bollworm pheromone trap counts were similar to last week and remain fairly low compared to historical averages. Tobacco budworm counts were slightly higher this week, but are still low fairly low. Southwestern corn borer trap catches have started to increase
I would like to call this a midseason rice update, but in actuality we have rice in Mississippi ranging from one leaf to late boot in places, but most of the rice crop should be at or reaching mid-season. Similar
An agronomic crops field day will be held at Cliff Heaton farms, just east of the intersection of Highway 61 and Highway 6. The field day will be held in the cotton field on the south side of the road. MSU Extension Specialists will be present to discuss topics in corn, cotton, grain sorghum, peanut, rice and soybean.
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
As some of the earliest planted rice is getting close to heading, it is time to start thinking about rice stink bug. We have been sweeping headed grass around the Delta for the past two weeks to determine what kind of populations are around.
This is a recycled article from 2012 and slightly updated but it fits well with recent calls. Sentences in italics have been added or updated since original posting. I have been getting quite a few calls about whether or not
By Keri Collins Lewis MSU Ag Communications STARKVILLE, Miss. — “Just mentioning bees and pesticides in the same sentence is sure to get a buzz,” said Angus Catchot, an entomologist with the Mississippi State University Extension Service. Media skirmishes about
This year we have seen tremendous population growth and expansion of Kudzu bugs from previous years. We have treated some acres already that were at threshold and I am confident that there will be many more to come based on what we are seeing around the state including the Delta region.
Over the last 7-10 days reports of sugarcane aphids in grain sorghum are becoming more frequent across the state. To date, I am not aware of any applications going out yet but numbers within some fields are definitely increasing. So far I have had about 10 reports of findings from the Delta region ranging from Cleveland to south of Inverness.
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
The MSU-DREC Rice Producer Field Day will be held in conjunction with the annual Mississippi Farm Bureau Federation Summer Rice Grower Meeting this year on the afternoon of July 30 at the Capps Center in Stoneville.. The Farm Bureau meeting
Mississippi State University will be hosting 5 scout schools this year. We have transitioned over the years to make these trainings much more diverse than insect pest alone. This year we will be including insects, disease, fertility, weed identification, and
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.
Over the last few weeks we have received numerous calls about brown stink bugs in seedling corn in the Delta region of the state. Stink bugs attack corn by feeding through the stem or even down in the whorl of small corn plants. Typically the area where they feed becomes chlorotic due to enzymes in their saliva.
Calls are starting to come in about stink bugs in heading wheat. It is not uncommon to find numerous stink bugs in wheat after head emergence. Species attacking wheat are typically rice stink bug and brown stink bugs but greens can sometimes be found. While it may seem very alarming, keep in mind it takes extremely high numbers to cause economic damage to heading wheat.
I have recently received a few call about slugs in corn and soybeans. I suspect this will increase when more crops emerge in the Hill region of the state as well. Slug problems usually start on corn first, then move to soybeans, then cotton in our area. This is only because we typically plant in this order. Slugs have been a sporadic problem in MS row crops over the years with increased occurrence since 2004. This has been exclusively a no-till or reduced till problem, particularly no-till behind a grass crop like corn or grain sorghum. Cool wet years are particularly favorable for slug problems to develop.
Mississippi State University will be hosting 5 scout schools this year. We have transitioned over the years to make these trainings much more diverse than insect pest alone. This year we will be including insects, disease, fertility, weed identification, and herbicide systems. There will be numerous hands on displays of insects, weeds, nutrient deficiencies in all major row crops, and fertilizer characteristics.
