Honey-bee

Although the honey bee s sting is unpleasant, this tiny creature is crucial to the world s agricultural economy. Honey bees produce more than jjilOO million worth of honey each year, and, more importantly, the pollination of numerous plants by honey bees is responsible for the production of i20 billion worth of crops in the United States alone. [Pg.319]

In the body, this reaction is reversed by the enzyme sucrase. This occurs in digestion, which makes glucose and fructose available for absorption into the blood. Honey bees also carry an enzyme that can hydrolyze sucrose. Honey consists mostly of a 1 1 mol mixture of glucose and fructose with a small amount of unreacted sucrose. [Pg.618]

As pesticides are applied, large numbers of honey bees and wild bees are poisoned resulting in not only a diminished honey crop, but perhaps more important, reduced crop pollination that is vital to agricultural production (51). The estimated yearly cost of reduced pollination and reduced honey production is about 230 million (Pimentel, D., in manuscript). [Pg.319]

Brown, Perth, Australia]. [Pg.143]

Venom collection is done by electrostimulation in honey bees [8] and by venom sac extraction in vespids [9]. While electrostimulation results in pure venom, venom sac extracts may be contaminated by some body proteins. The amoimt of venom injected by a sting varies from 50 to 140 pg dry weight for the honey bee, but was estimated to be much lower in vespids 1.7-3.1 pg for Vespula, 2.4-5 pg for Dolichovespula, and 4.2-17 pg for Polistes [10]. [Pg.146]

Bumble bee venom contains also a phospholipase A2 with partial identity to bee venom phospholipase Aj and a protease, but no melittin. Instead there are several small peptides called bombolitins [9]. There is limited cross-reactivity between honey bee and bumblebee venoms [2]. [Pg.146]

A number of allergens from both honey bee and vespid venoms have been cloned and expressed by either Escherichia coli or baculovirus-infected insect cells (table 1) phospholipase Aj [20], hyaluronidase [21], acid phosphatase [13] and Api m6 [14] from honey bee venom, as well as antigen 5 [22], phospholipase A and hyaluronidase [23] from vespid venom, and dipeptidylpeptidases from both bee and Vespula venoms [15, 16]. Their reactivity with human-specific IgE antibodies to the respective allergens has been documented [11-16, 22, 23] and their specificity is superior... [Pg.147]

The natural history of Hymenoptera venom anaphylaxis, that is the risk to develop anaphylaxis again when re-stung, has been analyzed in several prospective studies (table 3) [35-37], and in placebo or whole-body extract treated controls of prospective studies on venom immunotherapy [38-40]. It is higher in patients with a history of severe as compared to mild systemic anaphylactic reactions, and in honey bee than in vespid venom-allergic patients - most likely because of the smaller and less constant amoimt of venom applied by vespids [10,41]. A short interval between two stings increases the risk of anaphylaxis [25], but severe anaphylaxis may occur again even after intervals of 10-20 years or more. [Pg.149]

Sting provocation tests are often considered to be the gold standard, although they are less reliable in vespids than in honey bees [35-37, 41, 43]. They are commonly used to assure the efficacy of venom immunotherapy, but are generally considered as unethical in untreated patients with a history of venom anaphylaxis. [Pg.151]
