AgriLife Extension Entomology
We are located throughout the State and can provide advice on control of urban, structural, landscape, garden, veterinary and agricultural pests, and pests that are threats to human health. Our information is backed by science and research at Texas A&M and other universities and is made practical and relevant by Extension Entomologists, educators or agents who work in each county, right where you live.
What Are Our Extension Entomologists Saying?
- Cotton Fleahopper Numbers on the RiseBlasted Square from Cotton Fleahopper feeding (Photo by; S. Biles) Cotton fields range from pinhead square to early bloom. Most fields are susceptible to cotton fleahopper damage and the potential for bollworm losses. We are finding cotton fleahoppers in numbers as high as 1 per plant, averaging around 20-30 per 100 plants. Continue to scout for cotton fleahoppers through the [...] read morePublished on 2018-05-24By Stephen Biles
- Stink Bugs in SoybeansPhoto by: M. O. Way Soybeans fields are blooming and setting pods. This means they are in the most susceptible stage for yield and quality losses from stink bugs. We have been running through soybean fields and finding a few stink bugs. So far, we have yet to find stink bugs at threshold levels but all fields should be inspected [...] read morePublished on 2018-05-21By Stephen Biles

- Pest Management in Bloomimg Sorghum(Photo by S. Biles) Sorghum fields across the Mid-Coast of Texas are beginning to bloom. These fields are susceptible to sorghum midge damage. The sorghum midge is one of the most damaging insects of sorghum in Texas, especially in the southern half of the state. The adult sorghum midge is a small, fragile-looking orange-red fly with a yellow head, brown [...] read morePublished on 2018-05-18By Stephen Biles
- Squaring Cotton may have Cotton Fleahoppers(photo by S. Biles) Cotton maturity ranges from 2-3 leaf to matchhead square and some fields have multiple stages of cotton. Fields with squaring plants should be inspected weekly for Cotton Fleahoppers. This can be done visually or by using a small, 2-gallon bucket once the plants are 12 inches tall. Treat fields that exceed an economic threshold of 15 [...] read morePublished on 2018-05-16By Stephen Biles
- Harlequin bugsPEST: Harlequin bug (adults about 1/2" long, red & black in color)WHERE: cabbage, cauliflower, mustard, collards, etc.DAMAGE: piercing-sucking mouthparts suck plant juices leading to browning, wilting, & death of plantOPTIONS: pull out heavily infested plants; hand pick or vacuum insects off plants; pesticides (insecticidal soap, azadirachtin, permethrin, etc.) [...] read morePublished on 2018-05-11By Wizzie Brown
- Cotton Pest ReportCotton PlantingPlanting has been underway for awhile now in the Southern High Plains with a few fields north of Amarillo already planted or will be planted soon. Our soil temperatures are quickly rising with our hot dry conditions. The map to the right is from agweb.com and it illustrates soil temperatures at the 4” depth across the U.S for May [...] read morePublished on 2018-05-11By Ed Bynum, PhD
- Early Season Cotton PestsCotton in the field is as old as 3-4 leaf stage. This year’s crop has already been through a lot of turmoil from high winds and blowing sand to cold temperatures in the 40s. Early season cotton insect pests include thrips, aphids and mites. Seed treatments are usually effective in controlling these pests but sometimes problems will still occur. Mite [...] read morePublished on 2018-04-24By Stephen Biles
- Extension Entomology List of Sugarcane Resistant Sorghum HybridsExtension Entomologist Dr. Allen Knutson has released a list of sugarcane aphid resistant sorghum hybrids. The entries are based on multiple years of replicated field trials by AgriLife personnel Robert Bowling, John Gordy, Danielle Sekula, Mike Brewer and Allen Knutson. It should be noted that none of these trials are from the High Plains. The remainder of this article is [...] read morePublished on 2018-04-24By Pat Porter
