Comparative examinations of magnetic field effects on pupal development in three holometabolous insect species

Abstract

The development of new technologies in the last decades has actuated researches on effects of magnetic and electromagnetic fields on individual performance and physiological reactions in living systems. Our work is based on the model of pupal development and compares insect species belonging to different orders: Tenebrio molitor (Coleoptera), Drosophila melanogaster (Diptera) and Apis mellifera (Hymenoptera). A highly significant increase in the rate of adult eclosion was detected in all examined species reared under constant external magnetic field suggesting unique mechanisms of magnetic field influence on development of three evolutionary distant insect species.Razvoj novih tehnologija poslednjih decenija je pokrenuo istraživanja efekata magnetnih i elektromagnetnih polja na individualnu performansu i fiziološke reakcije u živim sistemima. Naš rad je baziran na modelu lutkinog razvića i poredi tri evolutivno udaljene vrste insekata koje pripadaju različitim redovima: Tenebrio molitor (Coleoptera), Drosophila melanogaster (Diptera) i Apis mellifera (Hymenoptera). Kod svih proučavanih vrsta je uočen statistički značajan porast brzine izleganja adulta pod uticajem spoljašnjeg magnetnog polja što ukazuje na jedinstvene mehanizme delovanja na procese razviće kod tri udaljene vrste insekata.nul
