The Colorado potato beetle, Leptinotarsa decemlineata, reared under diapause-inducing conditions will emerge fromthe soil as an adult and enter the diapause initiation phase, a periodwheremetabolic reserves are stockpiled before the beetles enter the nonfeeding diapause maintenance phase. Internal and external lipids were characterized during the diapause initiation phase (IP) and compared to the lipid profiles of nondiapausing adults. The primary internal lipids of both diapause IP and nondiapausing adults are triacylglycerols. Only trace amounts of internal lipids were detected in day 1 diapause IP adults. A dramatic increase in internal lipids was observed between day 7 and day 15 …
