Abstract

Pšenica je jedna od najvažnijih kultura u svijetu. U Hrvatskoj se prema podatcima iz
2017. godine proizvodi na površini od 116.150 ha s prosječnim prinosom zrna 5,9 t/ha. Za
vrijeme vegetacije napada ju veliki broj važnih štetnika, od kojih su najvažniji žitni balci, žitne
stjenice te lisne uši. Također u faunu pšenice ulaze i brojne korisne vrste koje smanjuju
populaciju štetnika te indiferentne koje su neutralne i nemaju niti pozitivan niti negativan
utjecaj na pšenicu, ali sudjeluju u biološkoj ravnoteži. Cilj istraživanja je utvrditi pojavu i
dinamiku populacije štetnika i njihovih prirodnih neprijatelja koji se javljaju u proizvodnji
pšenice. Istraživanje je provedeno na proizvodnim površinama pokušališta Agronomskog
fakulteta u Šašinovcu, na polju pšenice veličine 5,5 ha. Korištene su tri metode praćenja
populacije člankonožaca: entomološka mreža, „pitfall“ trapovi te vizualni pregledi biljaka.
Štetna, korisna i indiferentna fauna utvrđivala se jednom tjedno u razdoblju od 27.2.2019.
do 15.5.2019. U fauni štetnih člankonožaca u najvećoj brojnosti utvrđena je vrsta crveni žitni
balac (Oulema melanopus L.) te pripadnici reda dvokrilaca (Diptera). U fauni korisnih vrsta
člankonožaca utvrđen je najveći broj vrsta iz roda Harpalus, a zatim ostali pripadnici
porodice trčaka (Carabidae) te sedamtočkasta božja ovčica (Coccinella septempunctata L.),
dok su u fauni indiferentnih člankonožaca prevladavali skokunci (Collembola) i pauci
(Araneae).

Abstract (english)

Wheat is one of most important crops in the world. In Croatia, it is cultivated on
116.150 ha with yield of 5,9 t/ha. During the vegetation there are lots of pests that will can
do damage to wheat. The most important are cereal leaf beetle, wheat bugs and aphids.
There are also lots of beneficial arthropods that are controling the population of pests in
wheat and there are neutral species that have neither the positive or negative effect on
wheat plant health, but they are important for the biodiversity. The main goal of this
reasearch is to establish the population and dynamics of pests and there biological enemies
in wheat production. Reserch has been done on trial field of Agricultural college in Šašinovec
on the wheat field surface of 5,5 ha. Three types of methods were used to keep track of
population of arthropods: entomological net, „pitfall“ traps and visual inspection. Pests,
beneficial and neutral fauna has been tracked once a week, during the 12 weeks period,
starting from February 27th until May 15th of 2019. In the fauna of the harmful arthropods
the most prevalent species had been cereal leaf bug (Oulema melanopus L.) as well as, other
members of dipteran order (Diptera). In fauna of the usefull arthropods the most prevalent
species had been Harpalus spp., as well as, other members of order of ground beetles
(Carabidae) and seven spot ladybird (Coccinella septempunctata L.). Wherase, in the fauna of
the indiferent arthropods he most prevalent species had been (Collembola) and spiders
(Araneae)
