Checklist of insects associated with Salvinia minima Baker in Louisiana, USA

Abstract

This study presents a list of adult insects (excluding Diptera and Lepidoptera) collected from an infestation of an invasive aquatic weed, common salvinia (Salvinia minima Baker), in southern Louisiana, USA. Insects were sampled from May – November of 2009 and 2010 using floating pitfall traps. A total of 7,933 specimens were collected, representing seven orders, 70 families, and 235 species. Species of note include three currently undescribed species of Coleoptera, one previously undescribed braconid wasp, two new state records of Curculionidae, a new state generic record for the family Limnichidae, and a new record for the United States.
