As higher animals, humans pay attention to blood relationships between relatives, while as higher insects, will bees talk about blood relationships among bees? Do they also provide different "discounts" based on the kinship and kinship? Today, the editor of the Bee Tribe will take you to learn about whether there will be preferential treatment for relatives in the Bee Kingdom.
kinship index between worker bees
According to " Bee Biology ", in bee colonies, queen bee is mate with multiple males, and the semen of queen bee and male peaks are also randomly distributed, so the colony of bred bee breeding in this way, Many half-family subfamily constitute, so the kinship between bee colonies is actually relatively complicated.
The kinship index between worker bees in the bee colony can be expressed by formulas, and kinship r=0.25+0.5/n, where n represents the number of drones mated by the queen bee. The kinship index between worker bees and drones in the bee colony is 0.25; in the bee colony where multiple males mate, the kinship relationship between the queen bees and its offspring is 0.5; while the kinship value between the worker bees in the whole compatriot is as high as 0.75, which is more than that of the worker bees who have children themselves. The offspring relationship index is even higher than 0.5.
is exactly the case, which makes many people think that queen bees may be used as egg-laying machines by worker bees to give birth to sisters of their compatriots.
Worker bees will provide discounts to bees with high kinship
In the bee colony, the kinship of all compatriots is greater than that of half compatriots, and half compatriots are greater than that of all compatriots and sisters. It is precisely because of this special relationship between the bee colony, Theoretically, they will inevitably form a special preferential relationship between relatives. When nurturing, the worker bees will give priority to all compatriots and sisters, and then sort them according to kinship. If nurturing is chosen between all compatriots and half compatriots, the worker bees will give priority to all compatriots and may eliminate other half compatriots. Related research data of
shows that worker bees in the bee colony may provide special preferential treatment to bees with close kinship, which is specifically reflected in the two aspects of worker bees’ queen cultivation and feeding bees.
Promotional behaviors provided by cultivating queen bees
When a bee colony intends to cultivate queen bees, there are many eggs and larvae with different kinship in front of the worker bees. When worker bees choose eggs and larvae to raise kings, there will be conflicts among the subspecies in the swarm family. In bee colony, the kinship values of eggs, larvae and queen bee are actually the same, all of which are 0.5. From the perspective of queen bee, just use the eggs you laid on your own to raise the king.
is different for worker bees, because there are differences between all compatriots and half compatriots among worker bees. Therefore, sub-families definitely hope to use their family's eggs and larvae to raise the king in order to get the genes of their family More reproduction. According to relevant experiments, it can be found that when choosing different strains to raise the king, the worker bees will give priority to the eggs or larvae of their family to raise the king.
The preferential behavior experienced during feeding
Regarding whether worker bees are affected by kinship during feeding, Noonan et al. (1989) conducted relevant experiments. They chose different body colors drone semen to a queen bee artificially Inseminate , thereby establishing a bee colony with two subfamilies. The results show that when the worker bees want to feed the larvae, they will choose to feed the larvae of all siblings and half siblings.
To sum up, whether it is the cultivation of queen bees or feeding larvae, they will choose the one with the highest kinship value, which means that the honey kingdom also attaches great importance to "blood relationship" relationship and will provide preferential treatment to bees with close kinship. Behavior. The above is the relevant knowledge about preferential behaviors of relatives among workers’ bees that the editor knows. Of course, if you know more about preferential behaviors of workers’ bees, please leave a comment in the comment area, follow me, and learn more about bees!
