Alternatively, the bee may come into contact with an insecticide and transport it back to the colony in contaminated pollen or nectar or on its body, potentially causing widespread colony death. [3] Actual damage to bee populations is a function of toxicity and exposure of the compound, in combination with the mode of application.
The metabolism of bees and humans is sufficiently different that bees can safely collect nectars from plants that contain compounds toxic to humans. The honey produced by bees from these toxic nectars can be poisonous if consumed by humans. In addition, natural processes can introduce toxic substances into honey produced from nontoxic nectar.
A honey bee collecting nectar from an apricot flower.. The nectar resource in a given area depends on the kinds of flowering plants present and their blooming periods. Which kinds grow in an area depends on soil texture, soil pH, soil drainage, daily maximum and minimum temperatures, precipitation, extreme minimum winter temperature, and growing degre
Honey bee starvation is a problem for bees and beekeepers.Starvation may be caused by unfavorable weather, disease, long distance transportation or depleting food reserve. Over-harvesting of honey (and the lack of supplemental feeding) is the foremost cause for scarcity as bees are not left with enough of a honey store, though weather, disease, and disturbance can also cause problem
The Koschevnikov gland is a gland of the honeybee [1] located near the sting shaft.The gland produces an alarm pheromone that is released when a bee stings. The pheromone contains more than 40 different compounds, including pentylacetate, butyl acetate, 1-hexanol, n-butanol, 1-octanol, hexylacetate, octylacetate, and 2-nonanol.
Eufriesea purpurata is a species of eusocial orchid bee common in northeastern South America, particularly in the Amazon basin. [1] [2] It is an important pollinator of various wild plants, and it is noted for its attraction to various synthetic compounds used by humans, including some insecticides.
BPUs have a good mammalian tox profile. Diflubenzuron is considered to be of very low acute toxicity, and is approved by the WHO for treatment of drinking water as a mosquito larvicide. [8] BPUs have low acute toxicity against bees, low to moderate toxicity to fish, but high toxicity to aquatic invertebrates and crustaceans. [1]
Fluvalinate [1] is a synthetic pyrethroid chemical compound contained as an active agent in the products Apistan, [2] Klartan, and Minadox, that is an acaricide (specifically, a miticide), commonly used to control Varroa mites in honey bee colonies, [citation needed] infestations that constitute a significant disease of such insects.
