Download file to see previous pages This is a phenomenon that got witnessed in the United States between the years 2004 – 2005 where commercial beekeepers lost 30 – 90 per cent of their hives (Sainath, 2010).
Pesticides are a group of chemicals that became designed for selective toxicity to a certain type of species. They might be toxic to other species also but only to a certain degree lesser than for the targeted one. Pesticides usually have toxic effects on some non-targeted organisms too, using this case as an example, the bees. When they feed on neonicotyl insecticides, even at sub-lethal levels it eventually has an effect on their memory, behaviour and longevity (Timbrell, 2002). A prolonged exposure to the pesticides also tends to cause them to acquire chronic levels of pesticides in their body and also to the honey they make. Studies have gone ahead to show traces of such chemicals in honey which became consumed by human beings.
Miticides are a group of chemicals that essentially kill ticks and mites. The chemical became essentially intended for use in the control of mites that feed on plants and cause irritation to the bees. A particularly common example would be the varroa mite and the hive beetle. These pests harbour infectious pathogens that cause catastrophic damage to beekeeping operations. It is because of these facts that farmers/beekeepers tend to fumigate their beehives with the chemicals. The problem though arises when these exact chemicals affect the bees directly by adding additional stress to them. Miticides that got sprayed to plants are also likely to be subjected to exposure on the bees as they forage on the crops for nectar, pollen and other materials necessary for honey production.
Antibiotics are chemicals used to control infections by inhibiting growth and destroying microorganisms. Unlike pesticides and miticides which are curative chemical measures, these chemicals get administered as a preventive measure against brood diseases in a bee colony.   ...Download file to see next pagesRead More

Colony colapse disorder

...?Colony Collapse Disorder Colony Collapse Disorder (CCD) refers to a situation in which worker bees disappear from a beehive or a colony of European honeybees. In apiculture, the phenomenon of worker bees disappearing has always occurred throughout history. However, the use of the term Colony Collapse Disorder began when the number of disappearances of bee colonies greatly increased. There are certain conditions that occur simultaneously that characterize colonies that have been affected by CCD. These conditions include the presence of...

Colony Collapse Disorders in the Honeybee Colonies

...? Colony Collapse Disorders in the Honeybee Colonies The rate of honey production has faced a downward trend since the beginning of agrarian revolution. Obviously, this fall relies upon the under-productivity of the worker bees and infertility among the queen bees and the drone. Colony collapse disorder (CCD) is the appropriate phenomena found to provide a better description of this tragedy in the honeybee colonies. In order to unveil proper perception of the colony collapse disorders, this paper will analyze the toxicology of pesticides...

Colony Collapse Disorder

...?COLONY COLLAPSE DISORDER Characteristics of Colony Collapse Disorder Colony collapse disorder (CCD) is an idiopathic phenomenon in which there is a sudden loss of honey bee (Apis mellifera L.) colonies in the United States. Beekeepers initially notice it as an unexpected emptying of the hives, the absence of adult bees, with the young broods intact (Watanabe, 2008). Such occurrences in the beekeeping industry were recorded since 1869 (vanEngelsdorp et al., 2009). However, it was only in 2006 that Colony collapse disorder...

Colony Collapse Disorder

...? Colony Collapse Disorder Colony Collapse Disorder Colony Collapse Disorder often abbreviated as CCD is a phenomenon in which the worker honey bees from a hive abruptly disappear or vanish from their hives. This is a seriously increasing issue and this phenomenon has been greatly observed in northern parts of America and many counties in Europe. Disappearances of the bees have been occurring since the past ages but this particular term colony collapse disorder was given when there was seen a severe increase in the disappearances of the...

Colony Collapse Disorder

...? Colony Collapse Disorder The phenomena known as colony collapse disorder (CCD) have been documented for many years and it seems tohave first been noticed during the mid nineteenth century. Over the past few decades, however, their occurrence has increased in unprecedented rates to such an extent that many governments, especially in Europe and North America, have started taking steps to ensure that the situation is remedied. The CCD is a condition where the entire population of bees in a hive die off because of varying factors, both known and unknown and this occurs with devastating effects to the ecological system (Hamzelou, 2007)....

The Phenomena Of Colony Collapse Disorder In Honeybee Populations

...The Phenomena Of Colony Collapse Disorder In Honeybee Populations Introduction The phenomenon of honeybees’ Colony Collapse Disorder was noticed after the winter of the year 2006, when it was observed that most of the honeybees have just vanished. This brought the situation to an alarming point as many important crops were put to risk, thus threatening the food industry and supply chain as well, due to the vanishing of these homey bees, which are an important pollinator of fruits and vegetables. While disappearance of honeybees have been reported during earlier times also, the symptoms starting showing off the presence of colony collapse disorder (CCD) from 1980s. The symptoms include, among others, the presence of younger... that...

TOXICOLOGY

...Toxicology Answer Organic phosphate or OP compounds are a of chemicals used in both domestic and industrial sectors. They are commonly used in agriculture, chemical warfare and public health eradication programs. Some of the commonly used OP compounds are insecticides like parathion, malathion, dichlorvos, ethion, chlorpyrivos, diazinon and fenthion; antihelminthic agents like trichlorfon, herbicides like tricresyl phosphate and nerve gases like sarin, soman and tabun (Katz and Brooks, 2010). Most of these compounds are either amides, esters or thiol derivatives of phosphonic acid (Kamanyire and Karalliedde, 2004). These compounds are notorious for their health hazards. Most of the health effects are due to inhibition... -related...

Colony Collapse Disorder in Honey Bees

... Abstract The Honey bee population is currently facing a serious threat as several adult bee populations are failing to return to their hives. Scientists have named this phenomenon as the Colony Collapse Disorder due to the severity and unusual characteristics of the condition. As honey bees are considered to be the principle pollinators for many crops the onset of this disorder has resulted in the loss of several billions of dollars in revenue. The enormity of the situation has compelled scientist to unravel the cause behind the occurrence of such as disorder. Several causative factors such as pathogens, pesticides, antibiotics and other...
