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.
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.
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.
Fipronil is also used in Brazil and studies on the stingless bee Scaptotrigona postica have shown adverse reactions to the pesticide, including seizures, paralysis, and death with a lethal dose of .54 ng a.i./bee and a lethal concentration of .24 ng a.i./μl diet. These values are highly toxic in Scaptotrigona postica and bees in general. [24]
A Colors Show: Each installment of the platform's flagship series entails a performance by one or more artists in a minimalist room with floor and walls covered in a single color. A Colors Encore: This series usually features another track by an artist who participated in "A Colors Show". More liberties are taken in the making of the videos, in ...
