Thrips on fabaceous plants and weeds in an ecotone in northeastern Brazil

Tripes em plantas fabáceas e ervas daninhas em um ecótono no nordeste do Brasil

ABSTRACT:

Thrips (Thysanoptera) on 33 species of Fabaceae (ornamental and forage) and some weed species were surveyed in areas of caatinga-cerrado ecotone in northeastern Brazil. Twenty species of thrips were identified, all of which are associated for the first time with the plants sampled in this study, totaling 26 new host associations, based on collections of immatures. Five species are probably new to science, illustrating the diversity of thrips in the region. A few thrips species that also occur as pests in other regions of Brazil are discussed. Our data extend the distribution area of thrips species and provide basic information on their associated plants.

Key words:
pests; host association; identification; Thysanoptera.
