However, colony’s adaptation can affect their quality. We used Locomotor Activity Monitor (LAM25, Trikinetics, MA, USA) to track activity and sleep patterns of adult olive flies as immatures olives (F2-F3 generation) (>300 generations). Counts beam breaks caused by fly were an estimation its locomotor levels during light dark period. A longer than five minutes period adults’ inactivity was considered one episode. parameters found be dependent on sex, mating status rearing history. In virgin olives, males more active females increased towards end Mating decreased males, but not olive-reared flies. Laboratory had lower episodes shorter duration compared olives. describe diurnal B. adults fruits diet. discuss how pattern differences may flies’ ability compete with wild field.

Complex processes appear to link sleep duration and quality with dietary patterns. Numerous studies show healthful benefits of the Dietary Approaches Stop Hypertension (DASH) diet, but few have examined its association or quality. The current study tested cross-sectional associations DASH diet score among adults. Analyses participants were from 2005–2008 wave National Health Nutrition Examination Surveys (n = 3941 adults ≥30 years age, complete data). We performed sex- age group-stratified multiple OLS regression analyses total components as main predictors outcomes, adjusting sequentially for socio-demographic, behavioral health-related factors.

High saturated fat, sugar, and salt contents are a staple of Western diet (WD), contributing to obesity, metabolic syndrome, plethora other health risks. However, the combinatorial effects these ingredients have not been fully evaluated. Here, using wild-caught Drosophila simulans, we show that enriched with is more detrimental than each ingredient separately, resulting in significantly decreased lifespan, locomotor activity, sleep, reproductive function, mitochondrial function. These were pronounced female male flies. Adding regular flight exercise flies on WD markedly negated adverse WD. At molecular level, increased levels triglycerides caused dysfunction, while counterbalanced effects. Interestingly, fruit developed preference for after pre-exposure, which was averted by exercise. The results demonstrate aerobic can mitigate dietary fly physiology, feeding behavior.

Salt, commonly known as sodium chloride, is an important ingredient that the body requires in relatively minute quantities. However, consuming too much salt can lead to high blood pressure, heart disease and even disruption of circadian rhythms. The biological process rhythm was first studied Drosophila melanogaster well understood. Their locomotor activity gradually increases before light switched on off, a phenomenon called anticipation. In previous study, we showed high-salt diet (HSD) impairs morning anticipation behavior Drosophila. Here, found HSD did not significantly disrupt clock gene oscillation heads flies, nor it PERIOD protein neurons or peripheral tissues. Remarkably, neuronal plasticity axonal projections pacemaker neurons. Interestingly, increased excitability PDF mimics HSD, which causes impairment. Moreover, disrupts neurotransmitter-related processes brain. Taken together, our data show affects multiple functions physiological behaviors.
