Biological rhythms and vector insects
نویسنده
چکیده
The adjustment of all species, animals and plants, to the Earth's cyclic environments is ensured by their temporal organisation. The relationships between parasites, vectors and hosts rely greatly upon the synchronisation of their biological rhythms, especially circadian rhythms. In this short note, parasitic infections by Protozoa and by microfilariae have been chosen as examples of the dependence of successful transmission mechanisms on temporal components.

Using Insects\' Body Powder as a Complementary Growth Factor in Fungal Culture Media
Introduction: Nutritional requirements of fungi are essential for their successful growth in laboratories. Some fungi feed on the compounds present in the insects' bodies. The aim of this study was to evaluate the effect of insects' body powder (IBP) as a supplement for the fungi growth in culture media. Methods: We used 10 mg of IBP, obtained from Anopheles superpictus and Culex theileri mosqu...

متن کاملCircadian foraging rhythms of bumblebees monitored by radio-frequency identification.
Circadian clocks enable organisms to anticipate changes of environmental conditions. In social insects, the colony as a superorganism has a foraging rhythm aligned to the diurnal patterns of resource availability. Within this colony rhythm, the diurnal patterns of individuals are embedded, and various tasks within the colony are performed at different times by different individuals to best serv...
متن کاملEffects of Lycium barbarum. polysaccharide on type 2 diabetes mellitus rats by regulating biological rhythms
Objective(s): Type 2 diabetes mellitus (T2DM) is associated with circadian disruption. Our previous experimental results have showed that dietary Lycium barbarum. polysaccharide (LBP-4a) exhibited hypoglycemic and improving insulin resistance (IR) activities. This study was to explore the mechanisms of LBP-4a for improving hyperglycemia and IR by regulating biological rhythms in T2DM rats. Mat...

N-Phthaloyl GABA was administrated daily (50 mg/Kg body weight-i.p) to Wistar rats for 21 days and circadian rhythms of thiobarbituric acid reactive substances (TBARS) and antioxidants such as reduced glutathione (GSH), catalase (CAT) and superoxide dismutase (SOD) were studied under constant light (LL) conditions. Delayed acrophase of TBARS and advanced acrophase of antioxidants (GSH, CAT and ...
