Abstract
Svi kukci se moraju presvlačiti, jer im kutikula ograničava rast. S obzirom na tip metamorfoze, kukci mogu biti ametabolični, hemimetabolični ili holometabolični. Najviše utjecaja na presvlačenje i metamorfozu imaju mozak i žlijezde corpus cardiacum (CC), protorakalna žlijezda i corpus allatum (CA). Iz protorakalne žlijezde se luče fitoekdisoni koji potiču presvlačenje kukca, a iz CA se luči juvenilni hormon (JH) u čijoj odsutnosti počinje proces metamorfoze. Tokom metamorfoze se razvija odrasli kukac. Iz imaginalnih diskova se razvijaju organi karakteristični za odrasle kukce kao što su krila ili ticala. Odrasli kukci su spolno zreli i više se ne presvlače, osim u ametaboličnih kukaca i u slučaju hormonalnog poremećaja.
Abstract (english)
Insects have to moult because their cuticle prevents their growth. Regarding types of metamorphosis, insects can be ametabolous, hemimetabolous or holometabolous. Most influential glands for moulting and metamorphosis are the brain, corpus cardiacum (CC), prothoracic gland and corpus allatum (CA). The prothoracic gland secretes ecdysteroids which are responsible for moulting. The CA secretes juvenile hormone (JH) in the absence of which the metamorphosis starts. An adult insect is developed during metamorphosis. Organs characteristical for adults, such as wings or antennae, are developed from imaginal discs. Adult insects are fertile and no longer moult, except in cases of ametabolous insects and hormonal disorders.
