Colony Collapse Disorder (CCD) is affecting honey bee populations, causing bees to abruptly abandon their hives. The Israeli Acute Paralysis Virus (IAPV) has been implicated in bee declines, though it may not be the sole cause. Pollinators like bees are essential to agriculture as one-third of crop production relies on pollination. Common crops like apples, broccoli, and almonds require bee pollination to produce fruits and seeds. The loss of bee populations poses a serious threat to global food security and economies.

Honey Bee Colony Collapse Disorder (CCD)

“ Virus Implicated in Bee Decline” Israeli Acute Paralysis Virus (IAPV) was found in collapsed bee colonies 50-90% of bee colonies are affected by CCD IAPV may not be causal, but is associated As a virus, it is unlikely scientists will be able to develop a treatment if IAPV turns out to be the cause

Some Basic Facts About Pollinators Bees are just one of a category of animals which transfer pollen and seeds between plants. Pollinators facilitate plant reproduction, and that reproduction gives us much of what we eat. 30% of all food crops are pollinator dependent.

About Honey Bees Apis mellifera There are 7 extant species of honey bee, all of which belong to the genus Apis Several thousand worker bees support a single queen Eggs are laid singly in wax chambers Worker bees gather nectar, build the wax chambers, clean the hive, and feed the young Honey is produced as food for offspring when they have been weaned from royal jelly (which they are fed when hatched) While visiting flowers for nectar, workers inadvertently pollinate plants

Foods That Require Pollination Apples and oranges Broccoli Onions Blueberries Cherries Lemons and limes Cranberries Cucumbers (and pickles) Cantaloupes Carrots Avocados Almonds

Northern California Needs Bees! California imports millions of bees each growing season for its almond crop. This process involves half of all honey bees in the United States Almond trees must be pollinated to produce almonds properly California’s almond crop is worth about 2.3 Billion each season

The World Economy Needs Bees! Experts estimate that CCD is already costing 5.7 billion dollars world wide in lost crops and products each year

What is CCD? Colony Collapse Disorder is a condition affecting natural and domesticated honey bee colonies that causes the bees to leave the hive. This happens spontaneously, and without warning Outside of the hive, the bees soon die

Possible Causes of CCD Scientists are still trying to discover why CCD is happening. Some possible contributing factors include: Climate Change Pesticide Use Loss of natural habitat Parasites Viruses

The Worst Case Scenario … As part of complex ecosystems, the loss of pollinators would resonate in ways we haven’t begun to anticipate. … We would no longer be able to mass produce some of our favorite and most nutritious vegetables.

Why a Virus Might Spell ‘Disaster’ Viruses are much more difficult to treat than bacteria or most parasites. The best strategy we have is to vaccinate against them before an infection takes place. Anti-viral drugs are not 100% effective, and usually virus-specific.

Why are Viruses More Difficult Than Bacteria? Viruses use host cells to reproduce Viruses are not technically alive Viruses are simple and tough The first anti-viral was not discovered until the 1960’s, we have had antibiotics since 1928

What Can We Do About It? If you find bees on your property: - Don’t use pesticides! Call a qualified pest control person. If you want to do more: - There are many resources online, including www.aaas.org , www.nrdc.org , and many more. Scientists also need help observing and cataloging bee populations.

One More Thing We Can DO… Keep your own bee colony! Bees are easy to keep They do not sting impulsively There are books and classes on the subject (Bee Keeping For Dummies is widely recommended by online bee communities as a starting point.)

Discussion Ideas Does any one have any questions? Have you heard of CCD in the news before today? Would you ever consider ameture bee keeping as a hobby?

The document discusses the relationship between pesticide use for plant protection and beekeeping. It provides background on beekeeping and lists several crops that rely heavily on bee pollination. Studies show that pesticides can directly kill bees through contact or ingestion and indirectly impact bees by reducing foraging activity and influencing bee behavior. Different classes of pesticides produce varying symptoms in bees. The toxicity of common pesticides to bees varies, with some like cypermethrin and permethrin being highly toxic and others like endosulfan being less toxic. Factors like formulation, application period and time influence the level of bee poisoning from pesticides.

Bees are flying insects that pollinate flowering plants and produce honey. There are nearly 20,000 known species of bees found worldwide, except in Antarctica. Bees have three body parts - a head, thorax, and abdomen. Certain species like honey bees have a stinger on their abdomen. Bees evolved over 100 million years ago and likely originated in Asia. They play an important ecological role in plant reproduction and food production.

Apiculture Bee keepingDr. Dinesh C. Sharma

Beekeeping has a long history dating back thousands of years. It involves the domestic rearing of honey bees for honey and other products like beeswax, pollen, and bee packages. While early beekeeping methods were crude, innovations like Langstroth's movable frame hive in the 1850s helped industrialize the practice. Today, the US has over 2 million bee colonies, though numbers are decreasing. Issues like mites, diseases, and pesticides threaten bee populations and commercial beekeeping. However, sustainable beekeeping provides environmental and economic benefits by supporting pollination and providing additional income in developing areas.

Pesticides a threat to honey beesAaliya Afroz

��

This document discusses the threats that pesticides pose to honey bees. It notes that honey bees are essential pollinators for over 50 fruits and vegetables, providing a highly valuable ecosystem service worth $20-30 billion annually in the US. However, honey bee populations have been declining due to various stressors, including agricultural pesticides. Certain pesticides like neonicotinoids have been shown to impair honey bees' ability to return to hives and make them age faster. The document recommends best practices for pesticide application to reduce risks to bees, such as applying them at dusk to dawn when bees are not active. Joint efforts are needed between government, industry and other stakeholders to balance agricultural production and pollinator protection.

Colony collapse disorderalbenestra

��

Colony collapse disorder (CCD) describes the phenomenon where the majority of worker bees in a colony disappear, leaving the queen alone with a few nurse bees. CCD was first discovered in 1869 and given different names over time. A collapsed colony from CCD is characterized by the presence of capped brood, food, and the queen bee, but absence of most worker bees. Reports of disappearing honey-producing hives have decreased their numbers in the United States significantly since the 1940s. The exact causes of CCD are unknown but may include pesticides, mites, fungi, beekeeping practices, and commercial bee transport, acting together rather than individually.

Bees are the main pollinators of many important crops worldwide. Honey bees are especially effective pollinators due to adaptations like pollen baskets that help transfer pollen between flowers efficiently. Approximately 80% of crop pollination is done by honey bees. Lack of pollinators can significantly reduce crop yields, by up to 90% in some cases like vanilla and coffee. However, pollinator populations are declining due to factors like habitat loss, pesticides, parasites, and other threats. Proper management of bee hives is needed to utilize them for effective crop pollination. Overall, pollinators play a vital role in agriculture and food production globally.

Plant quarantine and phytosanitary certificationtusharamodugu

The word quarantine derives from the Italian word “quaranti giorni”, meaning ‘about fourty days’. After the Black Death arrived in Europe in 1347, observation and experience showed that the incubation time for the disease, from infection to the appearance of symptoms, was a little less than 40 days. Plant quarantine is defined as the legal enforcement of the measures aimed to prevent pests from spreading or to prevent them from multiplying further in case, they have already gained entry and have established in new restricted areas. The importance of imposing restrictions on the movement of pest-infested plants or plant materials from one country to another was realized by Ireland famine 1845, the late blight pathogen (Phytophthora infestans) introduced into Ireland from Central America resulted in almost total failure of the potato crop, the grapevine phylloxera was introduced into France from America around 1860, and the San Jose scale spread into the US in the latter part of the eighteenth century and caused severe damage. The first international plant protection convention (IPPC), the Phylloxera convention was signed at Berne on 3 November 1881 by five countries. This convention remained in force till 1951, when International Plant Protection Convention under FAO was established at Rome. This agreement was constituted with the purpose of securing common and effective action to prevent the introduction and spread of pests and diseases of plants and plant products. The first Quarantine Act in the US came into force on 1905, while India passed an act in 1914 entitled “Destructive Insect and Pests Act of 1914”. This was later supplemented by a more comprehensive act in 1917.

Feeding bees serves three main purposes: 1) to help a new hive expand and build comb, 2) to provide bees with food stores to survive the winter, and 3) to provide pollen or a substitute to help raise brood. A large batch pollen patty recipe is provided that uses brewer's yeast, sugar, honey, citric acid, canola oil, and optional essential oils. However, pollen patties may not be needed if bees bring in enough pollen naturally, and they can harbor small hive beetles. Feeding pollen patties early in spring may lead to an earlier start but also potential swarming, more hungry bees, and attracting small hive beetles, so experience

Honey bees are crucial pollinators for many fruits and vegetables. They pollinate about 30% of the food consumed in the US. However, honey bee populations have declined by 30-50% over the last 20 years due to various factors like pesticides, malnutrition, mites, and viruses. If honey bee populations continue to decline, it could significantly impact food prices and availability. There are steps people can take to help honey bees, such as planting bee-friendly gardens and donating to research on solving colony collapse disorder.

Pollinator decline refers to the reduction of pollinator populations in an ecosystem. This is problematic because pollinators such as bees play a crucial role in pollinating many crops that humans and animals rely on for food and medicine. Pesticide use has contributed significantly to pollinator decline by weakening bee immune systems and making them more vulnerable to parasites and pathogens, potentially leading to colony collapse disorder. The loss of pollinators could jeopardize crop yields and affect global food supplies and medicines. Individuals can help address pollinator decline by planting pollinator-friendly gardens and limiting pesticide usage.

BQCV (Black Queen Cell Virus) is a virus that primarily infects developing queen bee larvae, causing them to die and turn black in color. The virus is transmitted through nurse bees feeding infected brood food to larvae. Infected larvae first turn pale yellow and then progress to dark brown and black. This causes economic losses and damages beekeeping. The document outlines the characteristics, symptoms, spread, and management of BQCV infection in honey bee hives. Maintaining strong colonies with good nutrition, young queens, and hygienic apiary practices can help control and prevent the spread of the virus.

Bees are disappearing rapidly around the world, threatening global food supplies as they are essential for pollinating many crops. Beekeepers have reported half of their hives being empty with no dead bees found. While cell phones were once thought to be interfering with bee navigation, the cause is still unknown but believed to involve multiple factors. Pesticides are not helping the situation, and millions of crops depend on bee pollination. Some scientists believe the problem may have peaked as a parasite has been identified that contributes to colony collapse disorder. However, more research is still needed to determine the underlying cause and solution to stop the alarming bee deaths.

If bee populations continue to fall, it could lead to food shortages and increased prices, as well as public health issues from reduced nutrition. Some efforts to help bees include regulations on pesticide use and planting bee-friendly gardens and crops. The presentation promotes attending a upcoming Bee Fest event to raise awareness.

This document discusses the importance of bees as pollinators for one third of the world's food supply. It notes that bees are vital parts of the food chain and ecosystems. The document also warns that honeybee colonies are dying all over the world due to pesticides, which damage bees' nervous systems and ability to communicate. It provides recommendations for what individuals can do to help bees by avoiding pesticides, using eco-friendly alternatives, and planting bee-friendly plants.

This document discusses solitary bees and wasps. It explains that solitary bees and wasps do not live in hives, but rather females build and provision individual nest cells to lay eggs in. The females gather pollen, nectar or other foods to put in each cell before laying an egg and sealing it off. It encourages readers to help solitary bees and wasps by providing simple nesting habitats like untreated wood boards or bundles of bamboo with holes. This will help support these important pollinators and provide pest control. It also describes a new website, UF Native Buzz, that allows people to participate in citizen science by monitoring solitary bee and wasp nesting habitats.

Honey Bee Colony Collapse Disorder (Ccd)

1. Honey Bee Colony Collapse Disorder (CCD)

2. ��

3. “ Virus Implicated in Bee Decline” Israeli Acute Paralysis Virus (IAPV) was found in collapsed bee colonies 50-90% of bee colonies are affected by CCD IAPV may not be causal, but is associated As a virus, it is unlikely scientists will be able to develop a treatment if IAPV turns out to be the cause

4. Some Basic Facts About Pollinators Bees are just one of a category of animals which transfer pollen and seeds between plants. Pollinators facilitate plant reproduction, and that reproduction gives us much of what we eat. 30% of all food crops are pollinator dependent.

5. About Honey Bees Apis mellifera There are 7 extant species of honey bee, all of which belong to the genus Apis Several thousand worker bees support a single queen Eggs are laid singly in wax chambers Worker bees gather nectar, build the wax chambers, clean the hive, and feed the young Honey is produced as food for offspring when they have been weaned from royal jelly (which they are fed when hatched) While visiting flowers for nectar, workers inadvertently pollinate plants

6. Foods That Require Pollination Apples and oranges Broccoli Onions Blueberries Cherries Lemons and limes Cranberries Cucumbers (and pickles) Cantaloupes Carrots Avocados Almonds

7. Northern California Needs Bees! California imports millions of bees each growing season for its almond crop. This process involves half of all honey bees in the United States Almond trees must be pollinated to produce almonds properly California’s almond crop is worth about 2.3 Billion each season

8. The World Economy Needs Bees! Experts estimate that CCD is already costing 5.7 billion dollars world wide in lost crops and products each year

9. What is CCD? Colony Collapse Disorder is a condition affecting natural and domesticated honey bee colonies that causes the bees to leave the hive. This happens spontaneously, and without warning Outside of the hive, the bees soon die

10. Possible Causes of CCD Scientists are still trying to discover why CCD is happening. Some possible contributing factors include: Climate Change Pesticide Use Loss of natural habitat Parasites Viruses

11. The Worst Case Scenario … As part of complex ecosystems, the loss of pollinators would resonate in ways we haven’t begun to anticipate. … We would no longer be able to mass produce some of our favorite and most nutritious vegetables.

12. Why a Virus Might Spell ‘Disaster’ Viruses are much more difficult to treat than bacteria or most parasites. The best strategy we have is to vaccinate against them before an infection takes place. Anti-viral drugs are not 100% effective, and usually virus-specific.

13. Why are Viruses More Difficult Than Bacteria? Viruses use host cells to reproduce Viruses are not technically alive Viruses are simple and tough The first anti-viral was not discovered until the 1960’s, we have had antibiotics since 1928

14. What Can We Do About It? If you find bees on your property: - Don’t use pesticides! Call a qualified pest control person. If you want to do more: - There are many resources online, including www.aaas.org , www.nrdc.org , and many more. Scientists also need help observing and cataloging bee populations.

15. One More Thing We Can DO… Keep your own bee colony! Bees are easy to keep They do not sting impulsively There are books and classes on the subject (Bee Keeping For Dummies is widely recommended by online bee communities as a starting point.)

16. Discussion Ideas Does any one have any questions? Have you heard of CCD in the news before today? Would you ever consider ameture bee keeping as a hobby?
