For bees, many roads lead to social harmony Eusociality, where workers sacrifice their reproductive rights support the colony, has evolved repeatedly and represents most form of evolution in insects. Kapheim et al. looked across genomes 10 bee species with varying degrees sociality determine underlying genomic contributions. No one path led eusociality, but similarities were seen features such as increases gene regulation methylation. It also seems that selection pressures relaxed after...
The shift from solitary to social behavior is one of the major evolutionary transitions. Primitively eusocial bumblebees are uniquely placed illuminate evolution highly insect societies. Bumblebees also invaluable natural and agricultural pollinators, there widespread concern over recent population declines in some species. High-quality genomic data will inform key aspects bumblebee biology, including susceptibility implicated viability threats.We report high quality draft genome sequences...
Functionally sterile honey bee workers synthesize the yolk protein vitellogenin while performing nest tasks. The subsequent shift to foraging is linked a reduced and an increased juvenile hormone (JH) titer. JH principal controller of expression behavioral development. Yet, we show here that silencing causes significant increase in titer its putative receptor. Mathematically, corresponds dynamic dose-response. This role tuning endocrine system uncommon may elucidate how ancestral pathway...
The ectoparasitic mite Varroa destructor (Anderson & Trueman) is the most destructive pest of honey bee, Apis mellifera L., in Europe and United States. In temperate zones, main losses colonies from mites occur during colony overwintering. To obtain a deeper knowledge this phenomenon, we studied mites' impact on vitellogenin titer, total protein stores hemolymph, hemocyte characteristics, ecdysteroid titer adult bees. These physiological characteristics are indicators long-time survival...
Nutrient sensitive insulin-like peptides (ILPs) have profound effects on invertebrate metabolism, nutrient storage, fertility and aging. Many insects transcribe ILPs in specialized neurosecretory cells at changing levels correlated with life history. However, the major site of insect metabolism storage is not brain, but rather fat body, where functions ILP expression are rarely studied poorly understood. Fat body analogous to mammalian liver adipose tissue, stores that often correlate...
The difference in phenotypes of queens and workers is a hallmark the highly eusocial insects. caste dimorphism often described as switch-controlled polyphenism, which environmental conditions decide an individual's caste. Using theoretical modeling empirical data from honeybees, we show that there no discrete larval developmental switch. Instead, combination plasticity nurse worker feeding behavior make up colony-level social physiological system regulates development produces dimorphism....
SummaryDespite their tremendous economic importance, and apart from certain topics in the field of neurophysiology such as vision, olfaction, learning memory, honey bees are not a typical model system for studying general questions insect physiology. The reason is social lifestyle, which sets them "typical insect" and, during evolution, has resulted restructuring physiological pathways biochemical characteristics this insect. Not surprisingly, that have attracted most attention by...
Juvenile hormone (JH) controls key events in the honey bee life cycle, viz. caste development and age polyethism. We quantified transcript abundance of 24 genes involved JH biosynthetic pathway corpora allata-corpora cardiaca (CA-CC) complex. The expression six these showing relatively high was contrasted with CA size, hemolymph titer, as well degradation rates esterase (jhe) levels. Gene did not match contrasting titers queen worker fourth instar larvae, but jhe were significantly lower...
Major developmental transitions in multicellular organisms are driven by steroid hormones. In insects, these, together with juvenile hormone (JH), control development, metamorphosis, reproduction and aging, also suggested to play an important role caste differentiation of social insects. Here, we aimed determine how EcR transcription ecdysteroid titers related during honeybee postembryonic development what may actually be the this insect. addition, expected that knocking-down gene expression...
