HOMOPTERA ASSOCIATED WITH SUGARCANE FIELDS IN TEXAS

Sugarcane fields sampled during 1989 and 1990 yielded 36 homopteran sp ecies, including 9 aphid, 16 cicadellid and 7 delphacid species. Speci es were also collected from the families Cicadidae, Cixiidae, Membraci dae and Psyllidae. Although sampling techniques were different, our st udy documented 6 aphid, 13 cicadellid, and 5 delphacid species differe nt from those collected in a Florida sugarcane study (Hall 1988). The potential pest species Sipha flava (Forbes) (Aphididae), Saccharosydne saccharivora (Westwood) (Delphacidae) and Perkinsiella saccharicida K irkaldy (Delphacidae) were collected during both years. Several potent ial sugarcane disease-producing virus vectors were collected, includin g aphids, cicadellids, and delphacids. Surprisingly, no cereopids have been documented nor were any collected, although members of the gener a Aeneolamia and Prosapia are serious pests of sugarcane in the neotro pics.
