  2. Bees and toxic chemicals - Wikipedia

    en.wikipedia.org/wiki/Bees_and_toxic_chemicals

    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.

  3. Environmental impact of pesticides - Wikipedia

    They can destroy ecosystems and introduce all sorts of toxins to the people and animals that consume them. Even the non-active ingredients that are often assumed to be non-toxic can be the very toxic ingredient that causes harm. Perhaps, the most commonly seen issue with pesticides is their effect on pollinators. [8]

    Bees poisoned with carbaryl can take 2–3 days to die, appearing inactive as if cold. Sevin should never be sprayed on flowering crops, especially if bees are active and the crop requires pollination. Less toxic formulations exist. Highly toxic Carbofuran [21] Furadan: Carbamate: 7 – 14 days

  5. Osmia lignaria - Wikipedia

    en.wikipedia.org/wiki/Osmia_lignaria

    Orchard mason bees, like all mason bees, are very shy and only sting if they perceive serious danger. They do not attack to defend themselves. The stinger is actually an egg guide. Because of their docile behavior, mason bees are preferred by people who desire pollination in urban settings.

  6. Centris pallida - Wikipedia

    en.wikipedia.org/wiki/Centris_pallida

    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.

  7. Bee - Wikipedia

    en.wikipedia.org/wiki/Bee

    Bees collect pollen to feed their young, and have the necessary adaptations to do this. However, certain wasp species such as pollen wasps have similar behaviours, and a few species of bee scavenge from carcases to feed their offspring. [30] Solitary bees are important pollinators; they gather pollen to provision their nests with food for their ...

  8. List of crop plants pollinated by bees - Wikipedia

    en.wikipedia.org/wiki/List_of_crop_plants...

    This is a list of crop plants pollinated by bees along with how much crop yield is improved by bee pollination. [1] Most of them are pollinated in whole or part by honey bees and by the crop's natural pollinators such as bumblebees, orchard bees, squash bees, and solitary bees. Where the same plants have non-bee pollinators such as birds or ...

  9. Two-spotted bumble bee - Wikipedia

    en.wikipedia.org/wiki/Two-spotted_bumble_bee

    B. bimaculatus is an important pollinator in temperate forest regions as it is still abundant, unlike many other species of honey and bumble bees. They also pollinate a wide variety of plants. In addition, bumble bees can continue foraging even under sub-optimal conditions such as rain or clouds. [6]
