There is evidence that longevity and starvation resistance are determined by a common genetic mechanism. Starvation resistance in Drosophila strongly correlates with both fat content and longevity, and is affected by density during rearing. In this study, we examine how three species, Drosophila melanogaster, Drosophila ananassae and Drosophila willistoni, respond to three larval density treatm...

Neural systems controlling the vital functions of sleep and feeding in mammals are tightly interconnected: sleep deprivation promotes feeding, whereas starvation suppresses sleep. Here we show that starvation in Drosophila potently suppresses sleep, suggesting that these two homeostatically regulated behaviors are also integrated in flies. The sleep-suppressing effect of starvation is independe...

Outbreaking populations of the autumnal moth, Epirrita autumnata, are regularly facing a shortage of food and starvation. We found that starvation led to a prolonged larval development and a marked reduction in pupal weights. A decrease in female pupal weight caused a 50% decrease in the realized fecundity. Due to starvation the melanotic encapsulation rate decreased but the activity of PO — a ...

We used microarray and quantitative real-time PCR (qRT-PCR) analyses in adult female zebrafish (Danio rerio) to identify metabolic pathways regulated by starvation in the liver and brain. The transcriptome of whole zebrafish brain showed little response to 21 days of starvation. Only agouti-related protein 1 (agrp1) significantly responded, with increased expression in brains of starved fish. I...
