Hive management genetics of the queen. Queens and drones are selectively bred to increase the production of royal jelly. A good yield per hive is 5 kg per year. Bee venom (apitoxin) is obtained by stimulating the bee with an electric current that incite them to sting, releasing a drop of poison onto a glass slide. The crystallized venom can be collected and processed. In order to get 1 gram of dry venom, it is necessary to collect the apitoxin of 10,000 to 15,000 bees. Bee brood as such is generally not a commercial commodity. However, bee brood is edible, and is
Venom swelling, tissue necrosis, low blood pressure, convulsions, hemorrhage (varying by species of snake), respiratory paralysis, kidney failure, coma and death. Snake venom may have originated with duplication of genes that had been expressed in the salivary glands of ancestors. Venom is found in a few other reptiles such as the Mexican beaded lizard, the gila monster, and some monitor lizards including the Komodo dragon. Mass spectrometry showed that the mixture of proteins present in their venom is as complex as the mixture of proteins found in snake venom. Some lizards possess a venom gland; they form a hypothetical clade, Toxicofera,
