Mexican Rice Borer

Five species of parasitoids of larval stalkborer were evaluated in Texas in 1987 against the Mexican rice borer, Eoreuma loftini (Dyar), in field enclosures in rice, Oryza sativa L. The braconids, Alabagrus stigma (Brullé) and Allorhogas pyralophagus Marsh, and the bethylid, Goniozus natalensis Gordh, each parasitized >5% of the available E. loftini. The braconids, Apanteles minator Muesebeck and Macrocentrus prolificus Wharton, parasitized <1% of the available hosts. Allorhogas pyralophagus parasitized the highest percentage of borers, including 65.6% of the fifth- and sixth-instar E. loftini. Alabagrus stigma and G. natalensis parasitized fewer borers overall, although parasitism by A. stigma averaged 21.2% of small E. loftini in the rice leafsheaths. Alabagrus stigma, A. pyralophagus, and G. natalensis are candidates for further evaluation in the event that E. loftini becomes a pest of rice in Texas.

A New Species

AbstractFollowing the discovery of Lydella jaliscosp. n. (from Jalisco, Mexico), a parasite of the Mexican rice borer, Eoreuma loftini (Dyar) (Lepidoptera: Pyralidae), the limits of the genus Lydella Robineau-Desvoidy have been widened to include Diatraeophaga Townsend syn. n., Metoposisyrops Townsend syn. n., and Metagonistylum Townsend syn. n. All species regarded as belonging to Lydella are listed, with L. minense (Townsend) comb. n., L. oryzae (Townsend) comb. n., L. scirpophagae (Chao & Shi) comb. n., L. sesamiae (Mesnil) comb. n., and L. striatalis (Townsend) comb. n.
