Abstract

Bumbari su važni oprašivači i jedni od rijetkih opnokrilaca koji se polenom hrane čitav život.
Njihov životni ciklus je godišnji i posebna se pažnja pridaje matici koja je odgovorna za
stvaranje košnice. U poljoprivredi je opažena njihova korisnost te se već duže vremena koriste
kao oprašivači za staklenički uzgojene vrste. Vrste oprašene bumbarima brže sazriju i daju veće
plodove. Međutim, valja biti oprezan pri korištenju komercijalno uzgojenih vrsta jer su oni
češća meta štetnih nametnika i time mogu ugrožavati autohtone vrste bumbara. Utjecaj
pesticida na bumbare je zamjetniji jer, za razliku od pčela, oni stvaraju manje zajednice koje su
podložnije vanjskim utjecajima. Insekticidi poput imidakloprida remete prehrambene navike
bumbara te utječu na rast matice dok piretroidi utječu na veličinu jedinki koje su češće manje u
slučaju da se izlažu ovoj kemikaliji. Valja detaljnije istražiti utjecaj pesticida na populacije
bumbara.

Abstract (english)

Bumblebees are one of the most useful pollinators and one of the rare Hymenoptera that feed
on pollen their entire life. Their life cycle is annual, and the queen is of major importance as
she takes care of the hive. The agricultural potential of bumblebees is notable, and they are
commonly used as pollinators in glasshouses. Species that were pollinated by bumblebees gave
bigger fruits and matured faster. However, the usage of bred species should be cautious, as they
are more often affected by various parasites and therefore may endanger native species. In
comparison to honey bees, the pesticide effect on bumblebees is more pronounced, as the
bumblebees make smaller communities. Insecticides such as imidacloprid interfere with the
eating habits of bumblebees and affect the growth of the queen, while pyrethroids affect the
size of individuals, which are often smaller when exposed to this chemical. Consequently, they
are more sensitive to outer impacts. More details on the pesticide effect on bumblebee
populations are yet to be explored.
