Species identity crisis among New World members of the genus Heliothrips (Thysanoptera: Thripidae: Panchaetothripinae).

Until mid-1990s, Heliothrips was considered a genus without major identification problems, with only H. haemorrhoidalis spread worldwide. More recently, concerns have arisen regarding misidentifications of this pest species around the world, particularly with the description of H.

Ecological Interactions among Thrips, Soybean Plants, and Soybean Vein Necrosis Virus in Pennsylvania, USA.

Analysis of ecological and evolutionary aspects leading to durability of resistance in soybean cultivars against species (SVNV) (Bunyavirales: Tospoviridae) is important for the establishment of integrated pest management (IPM) across the United States, which is a leading exporter of soybeans in the world. SVNV is a seed- and thrips- (vector)-borne plant virus known from the USA and Canada to Egypt. We monitored the resistance of soybean cultivars against SVNV, surveyed thrips species on various crops including soybeans in Pennsylvania, and studied thrips overwintering hibernation behavior under field conditions.

What is a genus-interpreting structural diversity among species of urothripine Phlaeothripinae (Thysanoptera).

Variation within and between species is discussed in several obvious character states, including the number of visible antennal segments, prolongation of the anterior margin of the head, metaepimeral setae, and anal setae. As a result, Bebelothrips and Conocephalothrips are considered new synonyms of Amphibolothrips, and Baenothrips a new synonym of Stephanothrips. The revised generic classification suggests that urothripines are largely absent from the Neotropics, with four recorded species all likely to be introductions from the Old World.

The Panchaetothripinae (Thysanoptera, Thripidae) of Brazil, with one new Caliothrips species.

The subfamily Panchaetothripinae has been consistently recovered as a monophyletic group within Thripidae, comprising 144 species in 43 genera. Usually associated with plant leaves, 21 species from 12 genera have previously been recorded in Brazil, several being pests of a wide range of cultivated plants. Here we record four species as new to Brazil, Bradinothrips williamsi, Caliothrips nanus, C.

Merothrips meridionalis sp.n. (Thysanoptera: Merothripidae), a new fungivorous species from subtropical South America.

We here describe Merothrips meridionalis sp.n. based on specimens originally treated by J.

Heliothrips haemorrhoidalis and its relatives, with one new species and one new genus (Thysanoptera: Thripidae).

Heliothrips similis sp.n. is described as a close relative of the greenhouse thrips, Heliothrips haemorrhoidalis.
