The effects of constant temperature and an extremely low-frequency magnetic field (ELFMF, 50 Hz and average induction of 20 mT) on the activity of medial protocerebral neurosecretory neurons (A1 and A2) and corpora allata were investigated in Cerambyx cerdo L. larvae after 30 days of exposure. Both constant temperature of 23?C and the ELFMF led to decrease in activity of A1 and A2 neurosecretory neurons and increase in activity of corpora allata compared to the control group (larvae from natural conditions). The changes are more pronounced in A2 than A1 neurons. Ispitivan je uticaj konstantne temperature i ekstremno niskofrekventnog magnetnog polja (ELFMF, 50 Hz i prosecna indukcija 20mT) na aktivnost medijanih protocerebralnih neurosekretnih neurona (A1 i A2) i corpora allata kod larvi Cerambyx cerdo posle 30 dana izlaganja i konstantna temperatura od 23?C i ELFMF dovode do smanjenja aktivnosti A1 i A2 neurosekretnih neurona i povecanja aktivnosti corpora allata u poredjenju sa kontrolnom grupom (larve iz prirodnih uslova). Promene su vise izrazene kod A2 nego kod A1neurona.
