Insectos útiles y dañinos, inofensivos y peligrosos, imitadores. ¿Cómo y por qué pican los insectos? Precauciones y remedios contra las picaduras Por Giovanni Bosca Montaonda Ediciones
Esta guía está dirigida a los amantes de la fauna que deseen conocer mejor el mundo de los himenópteros, concretamente de los insectos "que pican". Naturalmente, en primer lugar aparecen las abejas, a cuya compleja y fascinante fisiología se dedica una gran parte, seguidas de sus otros muchos "primos", es decir, las abejas no melíferas; luego vienen parientes aún más lejanos, como los abejorros, las avispas y los avispones, y por último aquellos insectos que hacen todo lo posible por parecerse a ellos, y aquellos de entre los hexápodos de los que a menudo se cree erróneamente que tienen aguijón, y por lo tanto son peligrosos. Extremadamente rica en información entomológica, histórica y etológica, con fotografías y dibujos nítidos, esta guía puede leerse cómodamente en el sillón de casa, pero también puede ser una herramienta útil para quienes quieran o necesiten aprender a distinguir entre los distintos insectos en el campo, enseñándoles a evitar las picaduras y, si es necesario, a impedir que produzcan los efectos más peligrosos o indeseables.

Manuka UMF® honey from New Zealand has become one of the most sought-after floral honeys, recognized internationally for its unique antimicrobial properties. In fact, Manuka honey is unique in that it contains antimicrobial compounds that are not found in any other floral honey. This uniqueness has led to the development of a testing regime to certify the concentration of these compounds known as "unique manuka factor" or UMF®. The BeeNZ LTD company produces UMF-certified New Zealand manuka honey, which is the certification that guarantees the three key elements for manuka honey's antibacterial action. These elements are: the DHA (didroxyacetone) which is a substance found in the manuka flower; the bee going on this flower transfers this compound into the honey, which through enzymes produced by the bee will be naturally transformed into MGO (methylglyoxal). the content of MGO expressed in myriagrams per kg (mg/kg) of methylglyoxal, with a minimum of 83 mg/kg up to a maximum of 829 mg/kg. the minimum content of LEPTOSINE which simply translated is the pollen exclusive to the MANUKA flower which must be a minimum of 70% of the total in the jar. This began in the late 1980s when a range of floral honeys began to be tested in laboratories at the University of Waikato in New Zealand and it was discovered that honey derived from Manuka plant species had remarkable antimicrobial properties. It was shown that while all honey contained an enzyme called glucose oxidase that itself has an antimicrobial effect when glucose oxidase releases hydrogen peroxide in the presence of body serum, however, Manuka honey had something extra that when glucose oxidase was removed it still had potent antimicrobial properties. This factor was described as non-peroxide activity, later known as "unique manuka factor" or UMF®. It was only many years later that the compound responsible for this unique antimicrobial factor was identified as methylglyoxal. While it was known that nectar collected from the Manuka species produced honey containing methylglyoxal, it was also discovered that there was wide variation in the concentration of methylglyoxal in Manuka honey samples from different regions, seasons, and density of Manuka plants in a given location. Once methylglyoxal was identified as the main compound that contributed to the antimicrobial level of Manuka honey, questions remained about its source since it was not present in the nectar of Manuka flowers. Research continued and it was shown that the methylglyoxal in New Zealand Manuka honey comes from the chemical compound dihydroxyacetone (DHA). When Manuka honey is produced fresh by bees, it contains high levels of dihydroxyacetone and low levels of methylglyoxal; this gradually reverses when naturally occurring proteins and amino acids gradually convert dihydroxyacetone to methylglyoxal. It was therefore necessary to create a measurement and certification system to quantify the antimicrobial efficacy of Manuka honey thus developing the measurement of this honey, known as the "unique manuka factor" or UMF®. The method used is to compare individual honey samples in a colony of bacteria with a known concentration of phenol, a common antiseptic used in the medical industry. By comparing the antimicrobial efficacy of Manuka honey samples with a concentration of phenol, Manuka honey has a classification that guarantees its efficacy. For example, a Manuka honey sample that had the same antimicrobial effect as 15% phenol concentration is certified as UMF® 15+. Manuka UMF honey in which an index higher than UMF®10 is detected is considered active, but laboratory studies have shown that Manuka honey having non-peroxide activity levels of UMF® 15, UMF® 20 or higher is indeed active on a wide range of bacteria.Several international studies have demonstrated the active action of Manuka UMF® honey in combating bacterial strains. Manuka UMF® honey is an extraordinary product, its unique value stemming from the presence of compounds such as hydrogen peroxide, the high level of methylglyoxal expressed in terms of UMF®, along with antioxidants, polyphenols, phenolic acids, flavonoids and bee substances, all of which are vital to our health.
A great deal is heard about bees and the environment, and there are many who have approached beekeeping in recent years with curiosity and expectation. Few, on the other hand - among them the author - have an all-round experience of it, gained through decades of passionate beekeeping experience, readings, discussions, experiences and experiments, comparisons, conferences and travels. In short: Paolo Faccioli is one of the few authorized to push further into an unknown land where the beekeeper often dares not venture, despite having a sense and foreboding of it. Faccioli reconsiders his and our relationship with the tiny insect, in light of the most up-to-date environmental and ethical situations: indeed, confronting it from within, and viscerally. Here we find laid bare the fundamental knots of the human-apiculturist-animal relationship by proposing a florilegium of personal reflections that have arisen in the study of those thinkers who articulate one of the most lively and essential debates in contemporary philosophy, the one that goes under the very reductive label of animalism.
ORGANIC DRY FLOWER POLLEN 125 g Country of origin: ITALY Pollen is used in phytotherapy as a restorative because it is a complete food. Rich in proteins (6-30%); amino acids (15-22%); lipids (1-10%); unsaturated fatty acids and sterols; carbohydrates(up to 50% in the dry state); simple sugars (4-10%); water (12-20%); vitamins (vit.C, A, ac.pantothenic, ac.folic, B complex); enzymes;hormones; antibiotic factors; mineral salts (iron, calcium, magnesium potassium and zinc) and flavonoids. In its cell nucleus, pollen holds the secret of life: the DNA and RNA molecules that establish the vital function of all cells. Thanks to these substances it strengthens and nourishes the entire organism, combats states of mental and physical fatigue proving to be an excellent adaptogen and antioxidant. Used by athletes to increase resistance to fatigue and muscular exertion, it finds use in the physical activity of sportsmen for the supply of carbohydrates and lipids but above all as a source of protein and essential amino acids, superior to those of meat, eggs and cheese, which justify the tonic, anabolic properties given by the presence of 20 of the 22 amino acids used by the human body.
