Twenty-eight greenhouse screening materials, with predetermined airflow resistance values, were evaluated for exclusion of the silverleaf whitefly Bemisia argentifolii Perring & Bellows and thrips from a mixed-species population. Screens differed in exclusion efficacy, expressed as a percentage of the fiberglass window screen control and at an approach velocity of 92 m/min, from -35 to 94% for ...

Karnyothrips cyathomorphus sp. n. (Phlaeothripidae: Phlaeothripinae) is described as a new apterous species in the genus Karnyothrips Watson 1923, and it represents the fourth species of the genus to be recorded from China. A key to the Chinese species is given.

Specimens of Thripidae (Thysanoptera) species collected from Konya, Karaman and Mersin (2015-2017) were studied through molecular analyses as a part preliminary attempts to establish barcoding system for Thysanoptera in Turkey. The included 23 namely; Chirothrips kurdistanus zur Strassen, manicatus Haliday, Frankliniella intonsa (Trybom), occidentalis (Pergande), tenuicornis (Uzel), Limothrips ...

Thrips were sampled from six nectarine orchards in the Dry Central Interior, British Columbia, Canada, between April and June 1993 using yellow sticky cards on posts spaced around the perimeter of each orchard. Although 12 identified species of thrips were captured, >90% of individuals were the western flower thrips, Frankliniella occidentalis (Pergande). The flight patterns and abundances of w...

Pandanothrips gen. n. is described, with three new species inhabiting Pandanus: P. ryukyuensis sp. n. from Japan, P. wangi sp. n. from Malaysia, and P. hallingi sp. n. from Australia. This new genus shows no relationship to Projectothrips Moulton, the only other Thripinae genus known to be associated with Pandanus. Pandanothrips is superficially similar to Danothrips Bhatti, a genus of leaf fee...

Hindsiothrips sisakhti sp. n. is described from leaf litter in Iran, this being the first record of the genus from this country. A key is provided to the seven Phlaeothripinae genera recorded from Iran that are considered members of the Phlaeothrips-lineage, in which most species are fungus feeding: Aleurodothrips, Hindsiothrips, Hoplandrothrips, Hoplothrips, Idiothrips, Phlaeothrips and Sticto...

From Australia, 16 species of Hoplandrothrips are here recorded, of which 11 are newly described. An illustrated key is provided to 15 species, but Phloeothrips leai Karny cannot at present be recognised from its description. The generic relationships between Hoplandrothrips, Hoplothrips and some other Phlaeothripinae that live on freshly dead branches are briefly discussed.

Explaining the overwhelming success of sex among eukaryotes is difficult given the obvious costs of sex relative to asexuality. Different studies have shown that sex can provide benefits in spatially heterogeneous environments under specific conditions, but whether spatial heterogeneity commonly contributes to the maintenance of sex in natural populations remains unknown. We experimentally mani...

Haplothrips herajius sp. n. is described from leaves and flowers of a species of Suaeda in the south of Fars Province, Iran. This is the second Iranian species of Haplothrips with the unusual character state of extra setae on the metanotum. Information on variation in color and structure of the new species is provided. The similarities and host plant associations of this new species and Haploth...
