Economic Injury Level For Bermudagrass Stem Maggot (Diptera: Muscidae) In Bermudagrass Forage Production In Texas, V. Corriher-Olson, A. Knutson, F. Mitchell
IGC Proceedings (1997-2023)
The bermudagrass stem maggot, Atherigona reversura Villeneuve, was first reported damaging bermudagrass Cynodon dactylon (L.) Pers grown for forage in 2010 in the southeastern US. Damage results from individual larvae feeding internally on the vascular tissue just above the terminal node of the grass stem. Damage slows plant growth and reduces forage accumulation. To address the need for economic guidelines to manage this new pest, the relationship between the percent of stems damaged by bermudagrass stem maggot and forage yield was measured in commercial bermudagrass hay fields in northcentral Texas during 2016 and 2017. The slope of the linear regression, …
