20.500.12556/RUL-56748 Effect of temperature on cannibalism rate between green lacewings larvae (Chrysoperla carnea [Stephens], Neuroptera, Chrysopidae) Vpliv temperature na stopnjo kanibalizma med ličinkami navadne tenčičarice (Chrysoperla carnea Stephens, Neuroptera, Chrysopidae) Paper presents a larval cannibalism of green lacewings (Chrysoperla carnea ), which was observed during the laboratory bioassay on non-target effect of entomopathogenic nematodes against green lacewings larvae. The most probable reason for larval cannibalism were undersized Petri dishes in which the bioassay was performed. Due to large number of larvae per surface unit, frequent crossing of green lacewings larvae appeared and this consequently lead to cannibalism. In most cases larger, elder larv ae consumed smaller, younger larvae. Cannibalism increased with temperature rise and was the most intensive at 25 °C. At this temperature the larval mortality was 22.0 % after two days, while after four days the larval mortality reached 31.0 % V prispevku je predstavljen kanibalizem med ličinkami navadne tenčičarice (Chrysoperla carnea), ki se je pojavil pri laboratorijskem preučevanju neciljnega delovanja entomopatogenih ogorčic na ličinke omenjenega naravnega sovražnika. Najverjetnejši vzrok za pojav kanibalizma so bile premajhne petrijevke, v katerih je potekal poskus. Zaradi velikega števila ličink navadne tenčičarice na enoto površine, je prišlo do pogostega srečevanja ličink in posledično do kanibalizma. V večini primerov so ličinke višjega larvalnega stadija pojedle manjše ličinke. Kanibalizem se je povečeval z višanjem temperature in je bil najbolj intenziven pri 25 °C, kjer je bila smrtnost ličink dva dni po začetku poskusa 22,0 %, po štirih dneh pa 31,0 %. neuroptera pest insects pest control feeding habits nematodes biological control environmental factors population density mortality temperatura okoljski dejavniki kanibalizem navadna tenčičarica laboratorijski poskus entomopatogene ogorčice biotično varstvo rastlin true false false Biotehniška fakulteta Angleški jezik Slovenski jezik Delo ni kategorizirano 2015-07-10 17:38:22 2015-07-10 17:38:22 2022-08-01 12:34:05 0000-00-00 00:00:00 2009 0 0 Str. 5-9 Št. 1 Let. 93 2009 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 632 1581-9175 6021753 213840640 RAZ_Rojht_Helena_2009.pdf RAZ_Rojht_Helena_2009.pdf 1 A1B7E33AD1270B33B1B6CC2FC3DA383D b70b03b72bce83a8f87d064e863de684653af06fa46e3bcf2ab6989f6d72ff31 80b7c9e2-6194-11ec-abdb-00155dcfd717 20.500.12556/rul/f50e320d-496f-4b7b-ac72-db3465db74a4 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=152284 http://dx.doi.org/10.2478/v10014-009-0001-5 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=56759 Biotehniška fakulteta Acta agriculturae Slovenica 0 0 0
