This guide is aimed at wildlife lovers who want to learn more about the world of Hymenoptera, specifically those insects "that sting." First come, of course, the bees, to whose complex and fascinating physiology a large part is devoted, followed by the many other "cousins," i.e., non-melliferous bees; then follow even more distant relatives, such as bumblebees, wasps and hornets, and finally those insects that do everything to appear similar to them, and how many among the hexapods are often mistakenly believed to be equipped with stingers, and therefore dangerous. Very rich in entomological, historical and ethological information, with clear photographs and drawings, this guide can be read comfortably in the armchair, but it can be a useful tool for those who would or should learn to distinguish among the various insects in the field, then teaching how to avoid stings and, if necessary, how to avert them from producing the most dangerous or undesirable effects.

Varroa i fights them more effectively by zeroing out the winter brood. From this observation comes the Menna cage, designed and patented by Vincenzo Menna: a practical device that promotes the queen's rest in the colder months, and that brings all the varroa present in the Beehive more easily out into the open. The period of use varies from northern to southern Italy, but indicatively the first days of November will be the most suitable to start caging, and mid to late January those for caging. Considering that a regular family goes into production in 60 to 70 days from the release of the queen, it will be up to the beekeeper to adjust the period.
