Classical landscape ecology views spatial heterogeneity of habitats at relatively large 'human scales', and it is at such scales that most decisions of land management and nature conservation are made. The present paper makes use of a wider range of spatial scales to examine land mosaics from the 'fly point of view'. Taking examples from the Diptera faunas of mountainous land mosaics, it is demonstrated that: (i) large scale, 'patch content' landscape management has a direct bearing on Diptera community structure, (ii) borders between large scale patches are not necessarily perceived by flies (or other insects) in the same way as we perceive them, (iii) border complexity between patches at any scale may be as important as patch content as an axis of habitat definition. In this sense, 'border' is not to be confused with 'edge effects'. It is concluded that attention to both patch content and patch border complexity of land mosaics, viewed at the relevant spatial scales, is necessary for future successful conservation of Diptera biodiversity and for the efficient use of these insects in environmental assessment studies.  相似文献

叉茎管蚜蝇属Tigridemyia与墨管蚜蝇属 Mesembrius和美管蚜蝇属 Mallota形态相似,过去曾被作为后二属的亚属.但此属的雄性外生殖器阳茎的射精管端部4分叉与墨管蚜蝇属和美管蚜蝇属区别明显,因此,其属地位应予肯定.作者在整理中国的食蚜蝇标本时,发现该属1新种,刺腿叉茎管蚜蝇Tigridemyia acanthogemurilis sp.nov,加之过去已记录的1种,我国已知叉茎管蚜蝇属2种.本文描述了新种,并给出了中国已知2种的检索表和形态特征图及其分布.模式标本保存于华南农业大学植保系昆虫标本室.  相似文献

Predicted species lists are generated from regional species pools, coupled to codified habitat, microhabitat and biological trait data for the species. At site level, habitat association data are used to tailor the predicted list to site conditions and comparison between predicted and observed species lists is used to explore elements of site quality and site management options involving microhabitat and trait data for the species in the process. It is pointed out that this approach makes possible the interpretation of insect species lists by non-specialist site managers. At larger geographic scales, attributes of regional lists are identified. Throughout, the approach is considered in the context of its potential to contribute to resolution of issues relating to maintenance of biodiversity in Europe and the taxonomic group employed is the Syrphidae (Diptera).  相似文献

The ability of neonate larvae of the aquatic sciomyzids, Sepedon spinipes spinipes (Scopoli) and Dictya montana Steyskal (Diptera), to follow snail mucus trails was assessed using filter paper Y-mazes. On finding a mucus trail, larval behaviour of both species switched from unstimulated to stimulated searching behaviour, the latter being characterised by an increase in larval velocity and the frequency of lateral head taps. When fresh mucus trails were used, all of the neonates displayed a positive response and followed the mucus trail into the experimental arm. In addition, for S. s. spinipes and D. montana 80.00% and 86.67% of larvae respectively exhibited a strong response and followed the trail to its end. The stimulatory substance (s), however, appears to become inactive with time and after 45 minutes none of the tested larvae reached the trail end. These results are discussed in relation to the ability of aquatic species to forage outside of water for prey and the implications for their use in the biological control of nuisance snails.  相似文献

在整理美蓝蚜蝇属标本时发现2新种:缺纹美蓝蚜蝇Melangyna evittata sp.nov.,秦岭美蓝蚜蝇Melangyna qinlingensis sp.nov.,模式标本保存于陕西理工学院资源生物重点实验室,文中列出中国已知种的检索表。 缺纹美蓝蚜蝇,新种Melangyna evittata sp.nov.(图1 ~3) 雌性 未知。 ♂体长12mm;翅长10mm。 正模♂, 2004-05-05,陕西长安(太兴森林公园) ,霍科科采。 本种近似于Melangyna olsufjevi Violovitsh,但新种颜面暗棕褐色,缺黑色条纹,各足胫节棕褐色,缺亚端暗色环。新种以颜面暗棕褐色,缺暗色条纹命名,取拉丁字e(x)-(失去)和(vittatus)(具条纹的)构成新种名。 讨论新种颜面不具暗色条纹,符合亚属Meligramma特征,但后足基节后腹端角具毛簇,与该亚属特征不符;另一方面,后足基节后腹端角具黑色毛簇,符合亚属Melangyna特征,但颜面无黑色中条,与该亚属特征不符。所以其特征介于亚属Melangyna和Meligramma之间,其分类地位还有待进一步研究。 秦岭美蓝蚜蝇,新种Melangyna qinlingensis sp.nov.(图4 ~11) 雌性 未知。 ♂体长9.5mm;翅长9mm。 正模♂, 2002-07-07,陕西眉县(太白山) ,霍科科采。 本种近似于Melangyna olsufjevi Violovitsh,但新种复眼裸,颜面中条伸达触角基部,宽,小盾片被毛全黑色,足主要黑色,尾器不同。 新种以模式产地命名。  相似文献

A new species of the dipteran family Sciomyzidae is described from Iran: Limnia kassebeeri sp. n., which is similar to L. unguicornis (Scopoli, 1763) and L. paludicola Elberg, 1965, but differs from them by the reticulate pattern on the anal cell, the presence of one small seta on the anepisternum, in addition to fine hairs and the features of the genitalia.

The study of seed-beetles feeding on groundnuts (Arachis hypogaea), tamarind (Tamarindus indica) and other Caesalpinioideae from various areas of the Old World, enables the authors to characterize two different species of Caryedon that are usually confused. C. serratus (Ol.), usually known as the «groundnut seed-beetle», feeds on seeds of tamarind and various wild Caesalpinioideae in the genera Piliostigma, Cassia and Bauhinia. It is present in West and Central Africa. Detailed morphological studies associated with the analysis of part of the Cytochrome B gene show that another species, Caryedon gonagra, infests tamarind and other Caesalpinioideae in Egypt, South Asia, Australia and New Caledonia; this species also feeds in the seeds of a few Mimosoideae in the genera Acacia, Albizia and Dichrostachys. Caryedon gonagra and C. serratus appear as sister species deriving from an ancestor that may have fed on both Mimosoideae and Caesalpinioideae. Contrary to what happens in C. serratus, it seems that C. gonagra does not infest groundnuts under natural conditions. Larval development in groundnuts under laboratory conditions is however possible, as in several other Caryedon species.  相似文献
