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
Evolution of snake venom contain more than 100 distinct proteins. The composition of this mixture has been shown to vary geographically, and to be related to the prey species available in a certain region. Snake venom has generally evolved very quickly, with changes occurring faster in the venom than in the rest of the organism. Some traditional hypotheses of snake venom evolution have supported the idea that most snakes inject far more venom into their prey than is required to kill them; thus, venom composition would not be subject to natural selection. This is known as the "overkill" hypothesis. However, recent studies of the
