The model is numerically analyzed to determine the effects of infection on population and food storage dynamics and their subsequent implications towards colony survival and annual honey yield. Depending on the strength of disease, it is possible for either parasite fadeout, co-existence between bees...
Although many studies have demonstrated the apparent impacts of landscape change on the population dynamics and individual survival of the bees, the underpinning mechanisms remain largely unknown. On the other hand, an increasing body of literature has shown that bee gut symbionts are of great ...

In addition, we manipulated 26 brood cells of a population at the campus of Universidade de So Paulo by removing food from 13 brood cells. In this case, we checked the relationship between the body size of these bees and the amount of food consumed. We measured 241 individuals: 135 males...
ArticleOpen access26 May 2020 Introduction Among the rich phenomenology of organismal behavior, honey bees and other eusocial animals are distinguished by their remarkable, self-organizing, collective dynamics on the scale of an entire society. Functioning as a “super organism”1, a honey bee colon...
Viruses are omnipresent, yet the knowledge on drivers of viral prevalence in wild host populations is often limited. Biotic factors, such as sympatric managed host species, as well as abiotic factors, such as climatic variables, are likely to impact vira
Since then, the breeding population and the number of breeding sites rapidly increased and reached a maximum population of 207 pairs so far in 2015. The increase in population size and range within the last 14 years can be explained by two factors: At single sites, particularly large ...
Nucleus colonies of bees were established as previously described and relocated to a geographically isolated apiary and were grown to full-size colonies and equalized based on population prior to initiation of the study. The bees were maintained in eight-frame Langstroth equipment and kept as single...
A wide variety of other insects can be found on the flowers of roses. Most are considered destructive, such as thrips (Thysanoptera),chafers(Scarabeidae) and earwigs (Dermaptera). Population studies of thrips on rose flowers allowed the great AustralianecologistsAndrewartha and Birch to model ins...
Honey bees, the primary managed insect pollinator, suffer considerable losses due to Deformed wing virus (DWV), an RNA virus vectored by the mite Varroa destructor. Mite vectoring has resulted in the emergence of virulent DWV variants. The basis for such
