Abstract
Vogtia malloi Pastrana is a South American phytophagous insect specific to the economically important alligatorweed, Alternanthera phylloxeroides (Mart.) Griseb., an introduced aquatic pest in the southeastern United States. The current taxonomy of V. malloi is discussed, and the development, behavior, and ecology are given. This prospective biological control agent for alligatorweed produces 3–4 generations annually in the province of Buenos Aires, Argentina. Its life stages are: egg, 5 larval instars, prepupa, pupa, and adult. Pupae collected in late fall showed a delayed resumption of development even when they were exposed to favorable temperatures. Endo- and ectoparasitic Hymenoptera, both solitary and gregarious, were recovered from larvae and pupae.
