Abstract

Luk je jedna od najstarijih povrtnih kultura te se najčešće koristi kao prehrambeni proizvod. Od sjetve do skladištenja podložan je napadu različitih štetnih organizama, čija je posljedica smanjenje prinosa. Najvažnije štetne vrste člankonožaca na luku su tripsi, lisne uši te lukova i češnjakova muha. Osim štetne faune, na luku se mogu pojaviti i korisne vrste kukaca. Najpoznatije predatorske vrste kukaca pripadaju porodicama Coccinellidae, Carabidae i Syrphidae. U ovome dvomjesečnome istraživanju je vizualnim pregledom te žutim ljepljivim pločama praćena štetna, korisna i indiferentna fauna člankonožaca luka. Za svaku od navedenih metoda utvrđivanja, jednom je tjedno zabilježena sva ulovljena fauna člankonožaca. Rezultati istraživanja pokazuju najveću brojnost štetne faune. U pojedinim fazama rasta i razvoja luka zabilježen je proporcionalan rast u broju određenih štetnika i njihovih prirodnih neprijatelja. Zamijećena je i pojava štetnika kultura koje su se nalazile na okolnim parcelama.

Abstract (english)

An onion is one of the oldest vegetable crops, and it is also most often used as a food product. From sowing to storage, it is subject of attack of various harmful species, the consequence of which, is a yield reduction. The most important arthropods which damage the onion are thrips, aphids and onion and garlic flies. In addition to harmful fauna, useful insects can also appear. The most important predatory species of insects belong to Coccinellidae, Carabidae and Syrphidae families. In this two-month study, harmful, beneficial and indifferent fauna of onion arthropods was monitored by visual inspection and yellow sticky panels. For each of the mentioned methods of determination, all caught arthropod fauna was recorded once a week. The research results show that the highest number of fauna is harmul. In certain stages of onion growth and development, a proportional increase in the number of certain pest and their natural enemies was recorded. The appearance of pests of crops which were located on the surrounding plots has also been noticed.
