    Pesticide toxicity to beesFrom Wikipedia, the free encyclopedia

    Jump to: navigation, search

    Pesticides vary in their effects on bees. Contact pesticides are usually sprayed on plants and can kill bees

    when they crawl over sprayed surfaces of plants or other media. Systemic pesticides, on the other hand, are

    usually incorporated into the soil or onto seeds and move up into the stem, leaves, nectar, and pollen of plants[1]

    Dust and wettable powderpesticides tend to be more hazardous to bees than solutions or emulsifiable

    concentrates for contact pesticides.

    Actual damage to bee populations is a function of toxicity and exposure of the compound, in combination withthe mode of application. A systemic pesticide, which is incorporated into the soil or coated on seeds, may kill

    soil-dwelling insects, such as grubs ormole crickets as well as other insects, including bees, that are exposed

    to the leaves, fruits, pollen, and nectar of the treated plants. [2][3]

    [edit] Classification

    Insecticide toxicity is generally measured using acute contact toxicity valuesLD50 the exposure level that

    causes 50% of the population exposed to die. Toxicity thresholds are generally set at [4][5]

    highly toxic (acute LD50 < 2g/bee)

    moderately toxic (acute LD50 2 - 10.99g/bee)

    slightly toxic (acute LD50 11 - 100g/bee)

    non-toxic (acute LD50 > 100g/bee) to adult bees.

    [edit] Colony collapse disorder

    Colony collapse disorder(CCD) is a syndrome that is characterized by the sudden loss of adult bees from the

    hive. Many possible explanations for CCD have been proposed, but no one primary cause has been found. Th

    US Department of Agriculture (USDA) has indicated in a report to Congress that a combination of factorsmay be causing CCD, including pesticides, pathogens, and parasites, all of which have been found at high

    levels in affected bee hives.[6]

    For the majority of pesticides that are registered in the United States, EPA only requires a short-term contact

    toxicity test on adult honeybees. In some cases, the agency also receives short-term oral toxicity tests, whichare required in Europe. EPA's testing requirements do not account for sub-lethal effects to bees or effects on

    brood or larvae. Their testing requirements are also not designed to determine effects in bees from exposure to

    systemic pesticides. With Colony Collapse Disorder, whole hive tests in the field are needed in order todetermine the effects of a pesticide on bee colonies. To date, there are very few scientifically valid whole hive

    studies that can be used to determine the effects of pesticides on bee colonies. [7]

    [edit] Bee kill rate per hive

    The kill rate of bees in a single bee hive can be classified as: [8]

    < 100 bees per day - normal die off rate200-400 bees per day - low kill

    500-900 bees per day - moderate kill

    > 1000 bees per day - high kill

    one of the most toxicto honey bees, in

    certain formulations.

    These should never

    be sprayed onflowering crops

    especially if bees areactive and the croprequires pollination.

    There are

    formulations,however, which are

    determined to be less

    toxic (see tables).

    Usually, applicator-beekeeper

    communication can

    effectively be used toadequately protect

    bees from Sevin

    spirit. In 14 years of gardening professionally, I have never once been stung by a honeybee, even though Ivesheared, lopped, and pruned shrubs and flowers they were drinking from.

    If thats not enough keep in mind, our food supply still gets pollinated the old-fashioned way, with insects

    and lots and lots of honeybees. A drastic reduction in their numbers means terrible things for our plates. A

    Cornell University study estimated that every third bite of food in America is pollinated by honeybees.

    What can you do? While we dont know all the causes of their problems, a couple of things are certain to help

    We can be mindful of the pesticides we use, even the organic ones, and we can plant things in our gardens thaprovide nectar and pollen for them to eat. Today well talk about which pesticides you can use to kill the bad

    bugs while keeping honeybees alive and well.

    Pesticides that harm honeybees

    Some common pesticides you may have that are toxic to bees:

    Orthene (Acephate)

    Seven (Carbaryl)

    Diazinon (Spectracide, others)

    Bayer systemic (Imidacloprid), which gets into the pollen, may cause disorientation and death in bees

    Ambush, Pounce (Permethrin)

    Crossfire, Raid Flying Insect Killer (Resmethrin)

    Safe only if sprayed at dawn or dusk, when bees arent active

    These pesticides can hurt bees when wet, but arent harmful when dry, so if you use with care, can be bee-safe:

    Spinosad (insecticide)

    Pyrethrum (insecticide)

    Neem oil (fungicide, insecticide)

    Honeybee-safe pesticides

    While its not nice to spray while bees are around, these are fairly non-toxic to them:

    Sulfur (fungicide)

    Serenade (biological fungicide)

    Insecticidal soap

    Petroleum-based oils

    B.T. or Bacillus thuringiensis (biological control for caterpillars)

    Herbicides like Roundup and 2,4-D (though I much preferorganic herbicides)

    Of course,prevention of pestsandattraction of beneficialsusing plants can also help reduce the need forpesticides, as can the use of biological controls and beneficials, likehypoaspis miles mites for thripsor

    ladybugs or lacewings for aphids.

    Other tips for keeping bees safe while using pesticides:

    When in doubt, dont spray anything thats in full bloom. Bees arent attracted to plants that are budded or are

    at the point where their blossoms have dropped their petals.

    Spray anything you need to in the very early morning or right before dark so that bees are already safely

    home, and the pesticide can dry before bees come into contact with them.

    Careful not to contaminate the water that bees drink! Dont dump out your leftover pesticide in a way that

    leaves a puddle that bees might drink from.

    Use less-toxic formulations: Dusts are more hazardous to bees than liquids, and if you see any of the new

    micro-encapsulated formulas, just avoid them. These tiny capsules are the same size as pollen spheres, so arecarried back to the colony and shared.

    If youve got something thats particularly attractive to bees right next to your problem plant, consider not

    spraying or holding off till the other plant is no longer in bloom.

    One last note a big portion of the problem for honeybees also comes from agricultural uses, so eating

    organic really helps. In particular, the pesticides used on non-organic soy cause problems to honeybees.

    Pesticides and Honey Bees

    Toxicity of pesticides. Many materials that are used to control insects, weeds, and plant

    diseases are toxic to honey bees. These pesticides are placed in three groups in relation to thei

    effects on bees. Highly toxic** materials are those that kill bees on contact during application

    and for one or more days after treatment. Bees should be moved from the area if highly toxic

    materials are used on plants the bees are visiting. Among the materials in this group are the

    **Information extracted from Division of Agricultural Sciences, University of California, Leaflet 2883,

    February 1981, entitled "Protecting Honey Bees from Pesticides."

    Pesticides damage colonies in several ways. Most often the), kill the field bees without other effects on thecolony. In some instances the bees die in large numbers after returning to the hive Many bees are also lost in

    the field and the colony is weakened but not usually killed. Sometimes materials are carried by the bees to the

    hive where they kill brood, young bees, or the entire colony. Encapsulated pesticides, such as Penncap-M,

    have this potential of being carried to the hive.

    Methods of application. Losses from pesticides can be minimized by cooperation among beekeepers,

    farmers, and spray operators. Several basic principles should be followed to prevent losses of bees and to

    avoid injury to people and farm animals. The first of these is to apply the proper dosages and follow the

    recommendations on the label. The method of application is also a factor to consider. Ground application isgenerally safer than air application. The material and its formulation play important roles in its toxicity to

    bees. In general, sprays are safer than dusts, and emulsifiable concentrates are less toxic than wettable

    powders. Materials applied as granules are the least hazardous. At present there are no safe, effectiverepellents that can be used to keep bees away from treated areas.

    Proper timing of applications of pesticides allows the use of moderately toxic materials on crops visited by

    bees. Bees visit different crops at different times and for different periods during the day. The timing of

    treatment of a crop should relate to these bee visits. Squashes, pumpkins, and melons are attractive to beesearly in the day but close their blossoms in the afternoon. Afternoon and evening treatments, after the flowers

    close, are safest for bees. Sweet corn sheds pollen early and is visited by bees most heavily in the morning.

    Applications of insecticides to sweet corn are least dangerous when made as late as possible in the day,especially if the insecticide is kept off the tassels. For most crops, pesticide applications are safest for bees if

    they are made between 7 p.m. and 7 a.m.

    Number-keyed Notes on Pesticide Use

    1. California state regulations require permits for most uses of these chemicals, also for 2,4-Dand 2,4,5-T as herbicides but not as sprays on citrus.

    2. Laboratory- and field-tested mainly on alfalfa, citrus, cotton, ladino clover, milo and sweetcorn; all other chemicals were laboratory-tested only.

    3. Dibrom?, Phosdrin?, and tepp have such short residual activity that they kill only beescontacted at treatment time or shortly thereafter. Usually safe to use when bees are not inflight; not safe to use around colonies.

    4. Malathion has been applied on thousands of acres of alfalfa in bloom without serious lossof bees. However, occasional heavy losses have occurred, particularly under hightemperature conditions. If applied to alfalfa in bloom it should be only as a spray, andapplication should be made during the night or early in the morning when bees are notforaging in the field. Undiluted technical malathion spray (ULV) should not be used aroundbees.

    5. Nematicide.

    6. Di-Syston?(disulfoton) and other systemic pesticides used as seed treatments have notcaused bee losses.

    7. Temik?(aldicarb), although highly toxic to bees as a contact poison, is used only in granulaform, and extensive field usage has not caused bee losses.

    8. Defoliant.9. Desiccant.10.DDT has been withdrawn for most uses in U.S.A.11.Field doses have caused brood damage.

    12.The microencapsulated formulation of methyl parathion, known as Penncap-M?is highlytoxic to foraging bees, young hive bees, and brood. Overall, it is 13 times more hazardous

    to honey bees than the EC (emulsifiable concentrate) formulation. Penncap-M?is toohazardous to be applied to any area or within 1 mile of any area where and when bees arepresent.

    13.Plant growth regulator.14.Sticker/extender.15.Nitrification inhibitor.16.Chemical ripener.17.Insect growth regulator.18.Honey bee repellent.
