Fat content during attack and brood production of the ambrosia beetle <i>Trypodendron lineatum</i> (Oliv.)

ambrosia beetle, <i>Trypodendron lineatum</i>Abstract
After emergence from hibernation the ambrosia beetle, <i>Trypodendron lineatum</i> (Oliv.), flies to attractive host material where it arrives with about one-half the fat it had at the start of hibernation. Analyses of beetles during attack and brood production showed a steady increase in the fat content of males, starting 5 days after the attack. The fat content of the females declined in the first 5 days, then maintained this level for about 1 week after which it rapidly increased.References
