Honey bees are an invasive species throughout most of the world where they have been introduced, and the constant growth in the amount of these pollinators may possibly cause a decrease in native species. [21] Light pollution has been suggested a number of times as a possible reason for the possible decline in flying insects.
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.
Although estimates of crop pollination attributed to honey bees are uncertain, it is undeniable that bee pollination is a vital and economically valuable activity. [ 98 ] Ramalho (2004) demonstrates that stingless bees amount to approximately 70% of all bees foraging on flowers in the Brazilian Tropical Atlantic Rainforest even though they ...
Propoxur is highly toxic to honey bees. The LD50 for bees is greater than one ug/honey bee. [citation needed] Highly toxic Acephate [25] Orthene Organophosphate: 3 days Acephate is a broad-spectrum insecticide and is highly toxic to bees and other beneficial insects. [26] Moderately toxic Azinphos-methyl [27] Guthion, Methyl-Guthion ...

Female orchid bees act as pollinators, but of flowers other than orchids. Eusocial bees such as honey bees need an abundant and steady pollen source to multiply. Honey bee pollinating a plum tree. Bees are the most effective insect pollinators. Honey bees travel from flower to flower, collecting nectar (later converted to honey), and pollen ...
Like most other bees, they are essential for pollination. Specifically, they pollinate cacti, desert willow, and palo verde. [14] The tunneling ability of these bees aerates the soil, and this allows water from rain to reach plant roots quickly. Their nitrogen rich feces fertilizes the soil. [15] Their stings are mild, so they are not dangerous.
This leads to shifts in pollination syndromes and to some genera having a high diversity of pollination syndromes among species, suggesting that pollinators are a primary selective force driving diversity and speciation. [5] [6] Ophrys apifera is an orchid species that has a highly evolved plant-pollinator relationship. This specific species ...
