Abstract

Mrkva je jedna od deset najvažnijih povrtnih kultura za ljudsku prehranu. U svijetu se uzgaja na površini od 11,5 milijuna hektara, a godišnji prinos iznosi 428 milijuna tona. Mrkva se prvenstveno uzgaja zbog korijena koji se konzumira na razne načine. S obzirom da je korjenasto povrće, tijekom uzgoja najopasniji su podzemni štetnici koji oštećuju korijen. Istraživanje je provedeno na proizvodnim površinama Vrana d.o.o na površini od jednog hektra. Cilj istraživanja je utvrditi korisnu i štetnu faunu člankonožaca u intenzivnom nasadu mrkve i visinu njihove populacije s obzirom na razvojni stadij kulture. Za utvrđivanje faune člankonožaca koristili su se pregled tla prije sjetve, žute ljepljive ploče i vizualni pregled biljaka. Istraživanje se provodilo na poljoprivrednim površinama Vrana d.o.o. u razdoblju od ožujka do srpnja 2023. Prilikom pregleda tla prije sjetve, pronađeni su žičnjaci, dok najveći dio štetne faune člankonožaca čine jedinke iz reda dvokrilaca (Diptera) i jednakokrilaca (Homoptera). Korisnu faunu člankonožaca u najvećem broju zauzimaju ose pršilice (Syrphidae) i božje ovčice (Coccinellidae), a indiferentna fauna člankonožaca u najvećem broju se javlja iz porodice Thaumatomyia.

Abstract (english)

Carrot is one of the top ten essential vegetable crops for human consumption. Globally, it is cultivated on an area of 11.5 million hectares, with an annual yield of 428 million tons. Carrots are primarily grown for their roots, which are consumed in various ways. Due to being a root vegetable, the most significant threats during cultivation are underground pests that damage roots. The research was conducted on the production fileds of Vrana LLC, on an area of one hectare. The aim of the study is to determine the beneficial and harmful arthropod fauna in an intensive carrot plantation and assess their population levels based on the growth stage of the crop. To determine the arthropod fauna, pre-sowing soil inspection, yellow stickey traps, and visual plant inspection were employed. The research was conducted from March to July 2023 on fields at Vrana LLC. During the pre-sowing soil inspection, wireworms were found, while the majority of harmful arthropod fauna consisted of species from the order Diptera and order Homoptera. The beneficial arthropod fauna is predominantly composed of hoverflies (Syrphdae) and ladybugs (Coccinellidae), while the indifferent arthropod fauna mainly represented by the family Thaumatomyia.
