The sexuales of Thelaxes suberi (Hemiptera, Aphidoidea: Thelaxinae).

The oviparous female and male of Thelaxes suberi (del Guercio) are described and illustrated in detail for the first time. Notes on distribution, biology and host plants are presented, and keys are provided to the known sexuales of European Thelaxes species.

The Phylogeny of the Homoptera

Shenahweum minutum (Hemiptera, Aphidoidea: Drepanosiphinae)-taxonomic position and description of sexuales.

The oviparous female and winged male of Shenahweum minutum (Davis) are described and illustrated in detail for the first time. Notes on distribution and host plants are presented as well as additional taxonomic data on the genus.

Polyol metabolism in homopterans at high temperatures: accumulation of mannitol in aphids (Aphididae: Homoptera) and sorbitol in whiteflies (Aleyrodidae: Homoptera)

Examination of four species of aphid and four of whitefly showed that mannitol was present in each species of aphid, while sorbitol was present in the whitefly species. In the cotton aphid, Aphis gossypii Glover, the total body content of mannitol was considerably higher at noon than during the early morning. A similar increase in the sorbitol content of the silverleaf whitefly, Bemisia argenti...

DNA barcodes to identify species and explore diversity in the Adelgidae (Insecta: Hemiptera: Aphidoidea).

The Adelgidae are relatively small, cryptic insects, exhibiting complex life cycles with parthenogenetic reproduction. Due to these characteristics, the taxonomy of the group is problematic. Here, we test the effectiveness of the standard 658-bp barcode fragment from the 5'-end of the mitochondrial cytochrome c oxidase 1 gene (COI) in differentiating among 17 species of Adelgidae, in associatin...
