In Gabon, like elsewhere in Africa, crops are often sources of conflict between humans and wildlife. Wildlife damage to crops can drastically reduce income, amplifying poverty and creating a negative perception of wild animal conservation among rural people. In this context, crop-raiding animals like elephants quickly become "problem animals". To deter elephants from raiding crops beehives have...

A 30-year-old woman was referred to us on October 2, 1996, for evaluation of chronic idiopathic urticaria. She had worked as a hairdresser for 9 years with no skin or health problems other than insulindependent diabetes. The hives appeared 3 years ago, a few days after a permanent wave solution container accidentally ruptured spraying her face, chest, and arms with an 80% aqueous solution of gl...

Honey bees face serious threats. These include the presence of Varroa destructor mite in hives, which requires use acaricides to control. The constant recycling old wax exacerbates problem, and results accumulation residues beeswax, is a problem for viability colony. same happens with phytosanitary residues. In previous study, we implemented an efficient decontamination method using batch metha...

Bees have many natural enemies. It's not just bears that take a shine to the honey and/or the immature insects. There are also yeasts and parasitic insects that threaten to rob the colonies of the rewards of their hard labour. Researchers recently found that one parasite, the small hive beetle, even uses the bee's alarm pheromone as a signpost to congregate on stressed hives. With this and the ...

The effects of sublethal pesticide exposure to honey bee colonies may be significant but difficult to detect in the field using standard visual assessment methods. Here we describe methods to measure the quantities of adult bees, brood, and food resources by weighing hives and hive parts, by photographing frames, and by installing hives on scales and with internal sensors. Data from these perio...

We assessed the nontarget effects of ultra-low-volume (ULV) aerial adulticiding with two newwater-based, unsynergized pyrethroid formulations, Aqua-K-Othrine (FFAST antievaporant technology, 2% deltamethrin) and Pesguard S102 (10% d-phenothrin). A helicopter with GPS navigation technology was used. One application rate was tested per formulation that corresponded to 1.00 g (AI)/ha of deltamethr...

Insect pollinators are vital to the stability of a broad range both natural and anthropogenic ecosystems add billions dollars economy each year. Honey bees perhaps best studied insect pollinator due their economic cultural importance. Of particular interest researchers wide variety mechanisms honey use for thermoregulation, such as fanning cool air currents around hive careful selection insulat...
