Abstract

V letih 2019 in 2020 smo na Laboratorijskem polju Biotehniške fakultete v Ljubljani, na njivi s zelenjadnicami spremljali sezonsko dinamiko glagolke (Autographa gamma). Na robu njive smo postavili tri feromonske vabe in škodljivca spremljali od začetka aprila do konca oktobra. Z raziskavo smo želeli ugotoviti številčnost in čas pojavljanja metuljev, saj v Sloveniji doslej ta škodljivec še ni bil načrtno preučevan. S tem smo pridobili uporabne informacije o številu rodov na leto, ki jih ima ta škodljivec pri nas, kdaj se začne pojavljati in kakšna je številčnost ulovljenih metuljev glede na abiotične dejavnike, kot sta temperatura in padavine in biotične dejavnike, kot je razpoložljivost hrane za gosenice preučevanega škodljivca. Ugotovili smo, da se je škodljivec v letu 2019 pojavljal od začetka aprila pa do prve polovice oktobra. V letu 2020 se je škodljivec pojavil pozneje, in sicer v drugi polovici aprila in se je pojavljal vse do prve polovice novembra. V obeh letih je razvil tri rodove, najštevilčnejši je bil drugi rod. Ugotavljamo, da na pojavljanje in številčnost glagolke vplivata temperatura, padavine, relativna zračna vlaga in trajanje sončnega obsevanja. V prvem letu smo v feromonske vabe skupno ujeli 418 samcev, v drugem letu pa 594 samcev.

Secondary title: Seasonal dynamics of silver-y moth (Autographa gamma [L.], Lepidoptera, Noctuidae) in the field with vegetables
Secondary abstract: In 2019 and 2020, we investigated the seasonal dynamics of the silver-Y moth (Autographa gamma) st the Laboratory Field of the Biotechnical Faculty in Ljubljana, in a field with vegetables. We placed three pheromone baits on the edge of the field and monitored the pest from the beginning of April to the end of October. The aim of the research was to determine the abundance and time of occurrence of males, as this pest has not been systematically studied in Slovenia so far. This provides useful information on the number of generations per year that this pest has in our country, when it begins to appear and what is the number of adult males caught in relation to abiotic factors such as temperature and rainfall, and biotic factors such as the availability of food for caterpillars of the studied pest. We found that the pest appeared in 2019 from early April to the first half of October. In 2020, the pest appeared later, in the second half of April, and appeared until the first half of November. In both years silver-Y moth developed three generations, and the most numerous was the second generation. We find that the occurrence and abundance of the silver-Y moth are influenced by temperature, rainfall, air humidity and solar radiation. In the first year, a total of 418 adult males were caught in pheromone baits, and in the second year, 594 males.
