Abstract

Europski mračnjak agresivan je korov usjeva okopavina (kukuruz, soja, suncokret, šećerna repa). Svojim kompeticijskim sposobnostima utječe na kulturnu biljku, oduzima joj za život potrebne elemente te tako smanjuje njen prinos. Njegovo suzbijanje iziskuje znanje i stručnost, a potom i velika financijska sredstva te tako direktno utječe i na ekonomsku dobit poljoprivrednog gospodarstva. Biološko suzbijanje europskog mračnjaka pomoću kukaca uvelike bi smanjilo troškove njegovoga suzbijanja te... More smanjilo štetan utjecaj herbicida na okoliš, korisne organizme te čovjeka. U biološkom suzbijanju korova koriste se organizmi za koje je dokazano kako se hrane isključivo ciljanom vrstom, bez štetnog utjecaja i opasnosti za kultivirane biljke. Cilj ovoga rada bio je utvrditi entomofaunu vrste europski mračnjak te utvrditi njihov učinak i potencijal za primjenu u biološkom suzbijanju europskog mračnjaka. Istraživanje je provedeno na području Požeško-slavonske županije, na šest lokacija (Bučje, Jakšić, Vidovci, Velika, Pleternica i Kutjevo) u razdoblju od svibnja do kolovoza 2023. godine. U usjevima okopavina (kukuruz, soja, suncokret i šećerna repa ), u kojima se pojavio europski mračnjak, entomofauna je utvrđivana vizualnim pregledima. Tijekom pregleda biljaka praćena je pojava oštećenja biljnih organa nastala uslijed hranidbe uočenih kukaca. Slučajne vrste koje su utvrđene na biljkama europskog mračnjaka su Eurydema ventralis Kolenati, Coreus marginatus L., Phyllotreta sp. te Agriotes sp. za koje hranidba nije utvrđena. Od štetnih vrsta, utvrđene su lisne uši, Ostrinia nubilalis Hb., Liorhyssus hyalinus F., Carcharodus alceae Esp. i Heliothis armigera Hb. Less

Abstract (english)

The Velvetleaf is an aggressive weed of fallow crops (maize, soybeans, sunflower, sugar beet). With its competitive abilities, it affects the cultured plant, takes away the elements necessary for life and thus reduces its yield. Its suppression requires knowledge and expertise, and then large financial resources, thus directly affecting the economic profit of the agricultural economy. Biological control of the Velvetleaf using insects would greatly reduce the costs of its control and... More reduce the harmful impact of herbicides on the environment, beneficial organisms and humans. In the biological control of weeds, organisms are used that have been proven to feed exclusively on the target species, without harmful effects and danger to cultivated plants. The aim of this work was to determine the entomofauna of the Velvetleaf species and to determine their effect and potential for use in the biological control of the Velvetleaf. The research was conducted in the Požega-Slavonia County, at six locations (Bučje, Jakšić, Vidovci, Velika, Pleternica and Kutjevo) in the period from May to August 2023. The entomofauna was determined by visual inspections in the tillage crops (maize, soybean, sunflower and sugar beet), in which the Velvetleaf appeared. During the examination of the plants, the occurrence of damage to the plant organs caused by the feeding of the observed insects was monitored. Accidental species that have been found on Velvetleaf plants are Eurydema ventralis Kolenati, Coreus marginatus L., Phyllotreta sp. and Agriotes sp. for which nutrition has not been determined. Of the harmful species, aphids, Ostrinia nubilalis Hb., Liorhyssus hyalinus F., Carcharodus alceae Esp. and Heliothis armigera Hb. Less
