Parasitic mite, Varroa species (Parasitiformes: Varroidae) infesting the colonies of African honeybees, Apis mellifera scutellata (Hymenoptera: Apididae) in Tanzania
TLDR
The study showed that bee colonies were performing well probably that the African honeybees is adaptive and coexist with the mites, and authorities are advised to come up with an urgent monitoring programme to determine mite infestation levels and its effects to honeybee colonies in the managed and feral colonies.Abstract:
Assessment of parasitic mites (Varroa spp) infesting the colonies of African honeybees (Apis mellifera scutellata) was conducted in 25 districts of Tanzania mainland from August, 2010 - May, 2012. The research investigated the occurrence, prevalence and examined diagnostic features of Varroa mite’s infestation in colonies. Purposive sampling was used in each district; three apiaries and hives were randomly selected for inspection. Interviews, direct observation and experimental set up were the main data collection techniques used to gather the information. The results revealed the presence of Varroa mites in honeybee in 23 (92%) out of 25 studied districts. Out of 175 inspected honeybee colonies, 85 (48%) were found infected with mites. Infestation levels showed significant relationship with changing altitudes, being highest (219 mite count) at altitudes ranging between 1201 and 1500 m a.s.l. The study showed that bee colonies were performing well probably that the African honeybees is adaptive and co-exist with the mites. Authorities are advised to come up with an urgent monitoring programme to determine mite infestation levels and its effects to honeybee colonies in the managed and feral colonies.read more

TL;DR: A high precision classification model is proposed (hit rate over 90%), which can be useful to self-predict healthy, unhealthy, and collapsing bee colony health states.

TL;DR: A long-term Varroa mite monitoring strategy is recommended in areas of varying landscape and land use factors for a clear understanding of possible changes in mite infestation levels among African honeybees for informed decision making.

TL;DR: Various approaches for combating bee viral diseases are described: they include selection of tolerant bees, RNA interference and prevention of new pathogen introduction and none of these approaches are expected to lead to enhanced bee-health in the short term.
