Prilog poznavanju faune Trichoptera (Insecta) reke Toplice

The explorations of the Trichoptera (Insecta) larvae were conducted seasonally in the period from April 2000 until January 2001 in the Toplica River, the right tributary of the Kolubara River, on eight localities. 20 taxa were ascertained (Anabolia nervosa Curtis 1834, Potamophylax latipennis Curtis 1834, Hydropsyche angustipennis Curtis 1834, H. contubernalis McLachlan 1865, H. dissimulata Kumanski i Botosaneanu 1974, H. instabilisi Curtis 1834, H. saxonica McLachlan 1865, H. pellucidula Curtis 1834 Ryacophila pascoei McLachlan 1879, R. nubila Zetterstet, 1840, Athripsodes bilineatus Linne 1758, Polycentropus flavomaculatus Pictet 1834, Lepidostoma hirtum Fabricius 1775, Odontocerum albicorne Scopoli 1763, Sericostoma personatum Spence 1826, Allogamus, Stenophylax, Glossosoma, Helicopsyche Hydropsyche) classified into 10 families. The average number of the Trichoptera larvae in a wide range, from the specimens in which larvae were not ascertained (localities T1, T4, T8 in April, T6 and T7 in July, T5, T6 and T7 in October and all localities in January, except on locality T3) to 1832 ind/mz (locality T4 in October). The species from the Allogamus genus were most often found (on 5 localities), and the most numerous species is Hydropsyche angustipennis (1099 ind/mz). The species of the Helicopsyche genus have so far been ascertained in the springs in West Serbia and South-West Serbia, while in the Toplica River they were found in the upper and middle stream.Istraživanja larvi Trichoptera (Insecta) obavljena su sezonski u periodu od aprila 2000. do januara 2001. godine u reci Toplici, desnoj pritoki Kolubare na osam lokaliteta. Konstatovano je 20 taksona (Anabolia nervosa Curtis 1834 Potamophylax latipennis Curtis 1834, Hydropsyche angustipennis Curtis 1834 H. contubernalis McLachlan 1865, H. dissimulata Kumanski i Botosaneanu 1974 H. instabilisi Curtis 1834, H. saxonica McLachlan 1865, H. pellucidula Curtis 1834, Ryacophila pascoei McLachlan 1879, R. nubila Zetterstet 1840 Athripsodes bilineatus Linne 1758, Polycentropus flavomaculatus Pictet 1834 Lepidostoma hirtum Fabricius 1775, Odontocerum albicorne Scopoli 1763 Sericostoma personatum Spence 1826, Allogamus, Stenophylax, Glossosoma Helicopsyche, Hydropsyche) klasifikovanih u 10 familija. Prosečna brojnost larvi Trichoptera varirala je u širokom opsegu, od uzoraka gde larve nisu konstatovane (lokaliteti T1, T4, T8 u aprilu, T6 i T7 u julu, T5, T6 i T7 u oktobru i svi lokaliteti u januaru, osim na lokalitetu TZ) do 1832 ind/m2 (lokalitet T4 u oktobru). Najčešće su nalažene vrste roda Allogamus (na 5 lokaliteta), a najbrojnija vrsta je Hydropsyche angustipennis (1099 ind/mg). Vrste roda Helicopsyche do sada su konstatovane u izvorima Zapadne Srbije i Jugozapadne Srbije, dok su u reci Toplici nalažene u gornjem i srednjem toku
