Abstract:A honeydew-producing scale insect, Stigmacoccus garmilleri (Margarodidae), is associated with oak trees (Quercus spp.) in highland forests of Mexico. Although feeding by ants on scale-insect honeydew is more frequently documented in the literature, the honeydew produced by feeding instars of S. garmilleri is sufficient to provide nourishment for birds. This study elucidates bird use of honeydew in the tropical montane forests near Chiconquiaco, Veracruz, Mexico, and uncovers patterns in honeydew foraging. Over a 2-mo period, 40 trees harbouring scale insects, located in both forest and pasture areas, were intensely studied (160 h of bird-foraging observations along with quantitative measurements of honeydew production). Fifteen resident bird species and 18 migrant species were observed visiting observation trees. Approximately 72% of the resident bird species and 83% of the migrant bird species observed were recorded to forage on scale-insect honeydew. Audubon's warbler (Dendroica coronata auduboni) was the most active consumer and defender of the resource. Of 118 aggressive chases observed, only 9.65% occurred in forest observation trees, and 90.3% in pasture trees. Audubon's warbler demonstrated preferential defence and territorial patrolling of scale-insect honeydew in scattered pasture trees.

Abstract Liophloeothrips baharae sp. n. is described based on the holotype female collected on dead branches under oak trees in Zagros forests from Ilam province, western Iran. It is related to L. reperticus Ananthakrishnan and Muraleedharan, 1974 from India.

Great medieval scientist-polymath Abu Rayhan Al-Beruni (973–1050) wrote in his book “Pharmacognosy” about some kind of “worms” inhabiting willows in Azerbaijan and Southern Iran and used by native people for producing of a red dye. It was unclear during one thousand years which organisms Al-Beruni noted as those dye-producing “worms”. Some modern authors even suggested that the relevant medieval text was partly erroneous. To the contrary, in the present paper we, for the first time, consider some species of the felt scale insects (Coccinea: Eriococcidae) as the organisms, which have probably been used for the production of the red dye in the medieval countries of Western and Central Asia. These insects are several species from two closely related genera Acanthococcus Signoret, 1875 and Gossyparia Signo­ret, 1875. The review of biological characters, identification key, new figures and colour photographs are provided for the species of Acanthococcus and Gossyparia associated with Salix spp. in the Asiatic Region. Acanthococcus turanicus Matesova, 1967, syn. nov. is placed in synonymy with A. salicis (Borchsenius, 1938), and A. altaicus Matesova, 1967, syn. nov. is placed in synonymy with A. spiraeae Borchsenius, 1949. Earlier discovered synonymy of A. melnikensis (Hodgson et Trencheva, 2008) with A. aceris Signoret, 1875 is discussed. Some other dye-producing scale insects and their pigments are also briefly considered.
