Experiment: Sexual Cannibalism in Spiders

Experiments to test three different variables These variables are the assessment of female aggression, deprivation of food, and gradual interaction between males and females. When testing female aggression, virgin women experienced an incubation test incubation period to determine aggression. Give the spider 30 seconds to place the sputum and measure how long the interaction between cockroach and spider occurred. When testing food deficiency, the number of days women's spiders change without food was given on a daily basis in groups of 1, 3, and 5 days.

For example, in insects and spiders, sexually homogeneous foods, ie men eating men before, during, or after mating occur in many species including Chinese cockroach (Tenodera sinensis) and black widows spiders . It is well known that shark embryos dig into nests in the womb. The fight against spouses is common in the animal kingdom, sometimes even death. Several hummingbirds have even developed a potentially lethal decadent bill that men use in air warfare to penetrate each other. It is not a murder but a sexual competition, and in some cases an animal may mistakenly kill a potential partner. For example, a group of male buds may be pushed into women underwater, inevitably causing her to drown.

Dimorphism of size shows correlations related to sexual similarity, which is important in spiders (it also exists in insects such as prayers ticks). In spiders of large 2 wolf wolves, women who have limited food eat more often. Therefore, there is a high risk that men are less adaptable by preliminary mating of similar foods, and men will choose larger women for two reasons. Furthermore, the female reproductive ability has a positive correlation with the size of the female body, a larger female body type is chosen, which is seen in the family of Alanyi family. This method is used in all Argiope species including Argiope bruennichi. Some men use decorations such as combining women and silk, corresponding long legs, changing female meshes, mating when a woman eats, or providing a wedding to respond to cannibalism It evolved.
