Diet Quantity Influences Caste Determination

Diet Quantity Influences Caste Determination of Honey Bees
Download PDF

Provisioning is important in honeybees because nutritional cues determine whether a female becomes a reproductive queen or sterile worker. A qualitative difference between the larval diets of queens and workers is thought to drive this divergence; however, no single compound seems to be responsible. Diet quantity may have a role during honeybee caste determination yet has never been formally studied. Our goal was to determine the relative contributions of diet quantity and quality to queen development.

Pollination Protects Crop Value More Than Pesticide Use

Bee Pollination Outperforms Pesticides Pollination Outperforms PesticidesBloomberg published a news article on a scientific study conducted in France that showed the abundance of pollinators in rapeseed crops yielded a higher return than the use of pesticides.

"A four-year survey in France found higher yields and profits for rapeseed fields where there’s an abundance of pollinating insects, according to a study by agricultural researcher INRA and the country’s National Centre for Scientific Research published in Proceedings of the Royal Society."

Natural Biocide Disrupts Nestmate Recognition

Honeybee colonies are under the threat of many stressors, biotic and abiotic factors that strongly affect their survival. Recently, great attention has been directed at chemical pesticides, including their effects at sub-lethal doses on bee behaviour and colony success; whereas the potential side effects of natural biocides largely used in agriculture, such as entomopathogenic fungi, have received only marginal attention...
