The ecology and conservation of endangered saproxylic hoverflies (Diptera, Syrphidae) in Scotland
We describe eleven polymorphic microsatellite loci developed for Blera fallax using ‘next generation’ 454 whole genome shotgun sequencing, along with conditions for three multiplex PCR reactions. We tested allelic variation on forty B. fallax individuals from Scotland and Sweden. Allelic richness and expected heterozygosity were 3.03 ± 0.274 (mean ± Standard Deviation) and 0.391 ± 0.057 respect...
متن کاملThe behaviour of hoverfly larvae (Diptera, Syrphidae) lessens the effects of floral subsidy in agricultural landscapes
20 Modern agricultural landscapes favour crop pests: herbivores benefit from resource 21 concentration and/or the absence of natural enemies in large areas of intensively farmed fields 22 interspersed by small fragments of natural or non-crop habitats. 23 Conservation biological control (CBC) aims at increasing the functional diversity of 24 agricultural landscapes to make them more hospitable ...
متن کاملEristalis obscura (Loew) (Diptera, Syrphidae): synonyms and morphological variation in the Holarctic region
Eristalis obscura Loew, 1866, is Holarctic in distribution and E. pseudorupium Kanervo, 1938 and£. beltrami Telford, 1970 are junior synonyms of it. E. obscura shows a great morphological variation of the superior lobe in the male genitalia, which is documented by illustrations. The distinguishing characters of E. obscura and other similar species are briefly discussed. The male genitalia of E....
متن کاملA remarkable new species of Chalcosyrphus Curran from the Oriental Region (Diptera: Syrphidae).
Chalcosyrphus blanki sp. nov. is described from material collected in China, Thailand and Burma. The new species is outstanding because of its size and metallic blue coloration. It is remarkable that only a few specimens have been found so far, all from different countries and only with Malaise traps. The species was only collected at altitudes above 2500 m. It fits very well in the genus Chalc...
متن کاملRearing and observation of immature stages of the hoverfly Microdon katsurai (Diptera, Syrphidae)
BACKGROUND The hoverfly Microdon (Chymophila) katsurai Maruyama et Hironaga 2004 was speculated to be a myrmecophilous species associated with the ant Polyrhachis lamellidens based on observations of adults near the ant nest. However, there have been no reports regarding the observation of immature stages of this species in association with P. lamellidens. NEW INFORMATION For the first time, ...
