In 2008, a lucerne aphid parasitoid Aphidius ervi Haliday was first recorded in Slovenia. This oligophagous parasitoid is used as biological control agent against bigger aphid species. By sampling ...aphid mummies on different locations in Slovenia in 2008, we found parasitoid Aphidius ervi on nine host plants (corn, pea, alfalfa, red clover, winter wheat, oat, onion, potato and winter barley). Among 1812 primary parasitoids found in Slovenia in 2008, there were 46 individuals of Aphidius ervi; 21 male and 25 female parasitoids. In the present paper description of the species, its geographic distribution and host plant-aphid-parasitoid associations are given.
V letu 2008 smo v Sloveniji prvič ugotovili zastopanost parazitoida Aphidius ervi Haliday, ki parazitira zlasti listne uši na metuljnicah (Fabaceae). Ta oligofagni parazitoid se uporablja kot biotični agens večjih vrst listnih uši. Parazitoida Aphidius ervi smo v letu 2008 našli na 9 gostiteljskih rastlinah (koruza, grah, lucerna, črna detelja, ozimna pšenica, oves, čebula, krompir in ozimni ječmen) v Sloveniji, in sicer med vzorčenjem ušjih mumij. V letu 2008 smo nabrali 1812 primarnih parazitoidov, med njimi je bilo 46 osebkov vrste Aphidius ervi; 21 je bilo samcev in 25 samic. V prispevku je opisana vrsta, njena geografska razširjenost in povezava med gostiteljsko rastlino, ušjo ter parazitoidom.
In August 2008, we examined 95 soil samples for the occurrence of entomopathogenic nematodes in eastern part of Slovenia. 11 samples from 9 different locations were positive to entomopathogenic ...nematodes, but to this time only sample D54 was analysed. This soil sample was collected in Dravograd. Genetic studies proved that the nematode species in this sample was Heterorhabditis bacteriophora. This is the first record of Heterorhabditis nematode in Slovenia. Until now we confirmed the presence of four entomopathogenic nematode species in Slovenia; Steinernema affine, Steinernema carpocapsae, Steinernema feltiae and Steinernema kraussei. We expect that in Slovenia the use of these biological agents against insect pests will become important alternative to insecticides as it is known in many other countries of the world.
V avgustu 2008 smo preučili 95 talnih vzorcev, da bi ugotovili zastopanost entomopatogenih ogorčic v vzhodnem delu Slovenije. 11 vzorcev z devetih različnih lokacij je bilo pozitivnih na zastopanost entomopatogenih ogorčic. Doslej smo analizirali le vzorec D54, ki je bil odvzet blizu Dravograda. Genetska analiza je potrdila, da gre za vrsto Heterorhabditis bacteriophora. Gre za prvo najdbo ogorčice iz rodu Heterorhabditis v Sloveniji. Doslej smo v Sloveniji potrdili zastopanost 4 vrst entomopatogenih ogorčic, in sicer: Steinernema affine, Steinernema carpocapsae, Steinernema feltiae in Steinernema kraussei. Pričakujemo, da bo v Sloveniji uporaba omenjenih naravnih sovražnikov škodljivih žuželk postala pomembna alternativa insekticidom, kar je sicer že znano v številnih drugih državah sveta.
