Reproduction is one of the most powerful sources known on this earth. Reproduction allows animal, plants, and other organisms to thrive for generations. All organisms have to reproduce, otherwise their species will simply die out. Out of all of the organisms that reproduce, some of the most interesting include social insects of the Hymenoptera order. Social insects exhibit various interesting traits and strategies that they use for reproduction, such as the formation of a queen, worker reproduction, queen signaling or control, and sexual selection. Many of these traits and strategies can be seen in social wasp populations. Social wasps live in a hierarchy of a queen wasps and worker wasps. A single reproductive queen wasp produces all of …show more content…

Occasionally, female worker wasps will be able to lay unfertilized male eggs, even though they lack the ability to mate. However, while most worker females are unable to mate, a small percentage of 2% do have working ovaries (Ross 1985). This means that a small amount of worker wasps would be able to have viable offspring. This event generally happens because the colony where the worker wasps are reproducing is queenless. Generally, the event of worker-laid eggs fully developing is stopped by the queen, either through the queen control theory or the queen signaling theory. This is important to social wasp reproduction, as it shows why it is rare to find any other wasp besides the queen …show more content…

These methods of sexual selection include both before and after mating, and has competition between two males, two females, or competition between both genders of wasps. One of the most obvious forms of sexual selection in social wasps is between females. This is simply that queens of a high rank have higher mating success (Baer 2014). This method of sexual selection follows the natural hierarchy of social wasps, where one wasp is “in charge” (the queen), while others simply do the work for the colony (the workers). The other forms of sexual selection include the male to male competition of territory establishment, where males fight for territories and mark those territories to attract queens, and competition of male ornaments, which is a competition between males to see which one has the best ornaments and a competition between females for them to pick the male with the best ornaments. The males with bigger, darker dorsal spots generally have a better chance of mating (Baer 2014). This causes sexual selection competition between males, who try to have the darkest dorsal spots, and between females, who try to pick males with the darkest dorsal
