Spinosad is relatively nonpolar and not easily dissolved in water. [6] Spinosad is a novel mode-of-action insecticide derived from a family of natural products obtained by fermentation of S. spinosa. Spinosyns occur in over 20 natural forms, and over 200 synthetic forms (spinosoids) have been produced in the lab. [7]
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.
Bee-harming pesticides found in majority of English waterways Bee-harming pesticide use 'makes a mockery' of ban Bee-harming pesticide in emergency approval again
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.
Pesticides that harm bees were found in the "majority" of English waterways tested in the last year, according to data analysis by two environmental charities. The Rivers Trust and Wildlife and ...
Among others, Spinosad is widely documented to be highly toxic to honeybees. This article maks no mention of this fact, and instead states that is is not harmful to beneficial insects. —Preceding unsigned comment added by Wiltonj (talk • contribs) 19:20, 18 March 2008 (UTC) Thank you for your suggestion.
The World Health Organization estimates that 300,000 people die from self-harm each year in the Asia-Pacific region alone. [9] Most cases of intentional pesticide poisoning appear to be impulsive acts undertaken during stressful events, and the availability of pesticides strongly influences the incidence of self poisoning.
