whitish or lighter in color than unaffected plants. Only the top parts of the shoots are damaged. The lower leaves on the shoot remain green. The leaves above the feeding site wither and die.” To further complicate identifi cation, the larva may
have already developed into fl ies and left the plant before their damage is apparent, Corriher-Olson said. And there may be several generations each summer. The fl y’s life cycle is usually about 3 weeks, but it can be as short as 12 days. Dr. Larry Redmon, AgriLife Extension state forage
specialist, College Station, noted unconfi rmed reports of the Bermudagrass stem maggot have been coming to his offi ce since last year. “We had a call from a producer in Waller County
during 2012, which was the fi rst one I know of,” he said. “Additionally, we have had a report of what appears to be stem maggot damage in Comanche County this year.” The amount of yield reduction seems to depend upon
growing conditions, Corriher-Olson noted. “Typically, damage is more likely to be found in a
hay meadow, not in a grazed fi eld, because the fl ies won’t have time to complete their life cycle,” she said. Management strategies depend upon how near the

hay crop is to harvest when the damage is identifi ed, Corriher-Olson said. “If damage is found within 1 week of harvest, the
recommendation from Georgia is to harvest as soon as possible,” she said. “The longer they wait, the more likely the damage will spread, and there will be further reduction in yields.” If the pest and its damage are confi rmed 1 to 3 weeks
after the previous harvest, the recommendation is to cut the damaged areas, bale the damaged grass, and remove it from the fi elds, Corriher-Olson said. “The only threat posed by leaving the hay in the
fi eld is that it’ll compete with any attempts of the plant to regrow, therefore decreasing the yield of the next cutting. Leaving the hay in the fi eld does not increase infestation,” she said. The pest can also be controlled with foliar applica-
tions of several inexpensive insecticides, Knutson said. Current recommendations are to treat after a cutting if damage levels are high. All 3 specialists recommend producers who suspect
they have an infestation contact the AgriLife Extension agent in their county to confi rm they have the pest before treating or using other control measures.
