20.500.12556/DKUM-69233 Vpliv protitočne mreže na populacijsko dinamiko rdeče sadne pršice (panonychus ulmi Koch) in plenilskih pršic (phytoseiidae) v nasadu jablan Influences of hail-net on the population dynamics of red mite (panonychus ulmi Koch) and phytoseiid mites in an apple orchard V letih 2008–2012 smo v Sadjarskem centru Maribor – Gačnik proučevali vpliv protitočne mreže na pojavnost (populacijsko dinamiko) rdeče sadne pršice (Panonychus ulmi Koch) (RSP) in plenilskih pršic (Phytoseiidae) (PP) v nasadu jablan, sort ˈGalaˈ, ˈFujiˈ in ˈBraeburnˈ. Slednje so bile izbrane po principu boljših ali slabših gostiteljev za rdečo sadno pršico. Enak sklop zaporedja sort se je ponovil v nasadu, pokritem s črno protitočno mrežo, in v nasadu, ki s črno protitočno mrežo ni bil pokrit. Z raziskavo smo potrdili, da je vpliv sorte na pojav spremljanih škodljivcev večji, kot je vpliv mreže, saj sorta značilno vpliva na populacijsko dinamiko RSP in PP. Značilen vpliv protitočne mreže na pojav RSP in PP je bil potrjen le pri sortiˈBraeburnˈ, kjer je mreža imela značilen zaviralni učinek na RSP. Between the years 2008 - 2012 the Fruit Growing Center Maribor-Gačnik studied the influence of the anti-hail net on the appearance (population dynamics) of European red mites (Panonychus ulmi Koch) (ERM) and predatory mites (Phytoseiidae) (PM) in the apple orchard. The research was carried out on three different varieties of apple trees ˈGalaˈ, ˈFujiˈ and ˈBraeburnˈ. The varieties were selected on the principle of better and worse hosts for red spider mite. The identical sequence of the same varieties was repeated in an orchard covered with a black anti-hail net and in an orchard, that was uncovered by a black anti-hail net. The study confirmed that the influence of the variety was greater than the impact of the coverage of the apple orchards with the net. The variety had a significant influence on the population dynamics of ERM and PM. The influence of net - covered apple trees on the ERM and PM was confirmed only in the varietyˈBraeburnˈ where the use of the net had a significantly reduced the population of ERM. jablana / protitočna mreža / plenilske pršice / rdeča sadna pršica apple / anti hail-net / predatory mites / European red mite true true false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2017-12-13 08:20:11 2017-12-21 11:22:58 2022-08-01 17:03:37 2019-07-11 17:25:34 2017 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:DCZ0NROY MAG_Donik_Purgaj_Biserka_2017.pdf MAG_Donik_Purgaj_Biserka_2017.pdf 1 AB6856EF0DB6243B7D2498552D148407 aa22cf49bf1620d02ebdcf27d695f05af49d50f9b8d607d45c1c04de33de436b 8f48d9a1-7c0f-11eb-bb7a-00155d0001ca 20.500.12556/dkum/15da1de7-46a9-4309-af03-b2e20b158fd2 https://dk.um.si/Dokument.php?lang=slv&id=120938 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
