    Description

    The biology of a pine needle sheath midge, Contarinia acuta Gagné is described for a new host in Louisiana. This midge was found feeding within the needle sheath on elongating needles of loblolly pine, P. taeda L. Needle droop and partial defoliation were evident on heavily infested trees. Overwintering C. acuta adults were first detected emerging from the soil on April 30, 1984. The population progressed through four generations between May 11 and September 17, 1984.
