Pasture mealybugs are worth another look in North Texas.
When I posted about this invasive pasture pest in August, it was an emerging issue worth watching. Since then, the situation has continued to change.

Texas A&M AgriLife's current infestation map now shows verified pasture mealybug infestations in Wise County, along with nearby Denton, Tarrant and Parker counties.
A few things worth noting:
• Current Texas A&M reporting says pasture mealybug has been confirmed in 79 Texas counties.
• AgriLife cautions that the actual range of infestation is probably greater than the counties currently verified on its map.
• Since my August post, an emergency exemption has been approved in Texas for a pesticide product to help control pasture mealybug. Landowners and producers considering treatment should follow current AgriLife guidance and product-label requirements.
• Pasture decline can have several causes. Yellowing, reddening, thinning or dying grass should not automatically be assumed to be pasture mealybug.
For North Texas landowners, this is becoming a much more local issue. If you're seeing unusual changes in a pasture, it may be worth taking a closer look rather than assuming drought or another familiar cause.
Texas A&M AgriLife recommends contacting your local County Extension Agent for help with suspected infestations.
