Spider Nephila pilipes types have unique mating behavior. The males of
this species will be stripped palp or organs such as the penis after use
for mating. Organs will be allowed to clog the female reproductive
tract.
Blockage of the reproductive tract of the males is a form of competition. The stud will not allow other males to marry females who had he marry first.
Until now, the blockage by stud is the only way the formation of plugs in the female reproductive tract. Until scientists discovered that without any males, females may form a plug as a way of refusing to have sex or marry.
Matjaz Kuntnerdari Smithsonian national Museum of Natural History and several students investigate the blockage by the female's behavior. The results of the study published in the journal PLoS ONE on July 19, 2012 last.
To find out, researchers conducted experiments to attempt mating with multiple males are small and some large females polyandry. Researchers did not find the presence of plugs for mating activity.
Investigators later learned that the plug is formed of a red liquid then hardens slightly. Formation occurs during the process of laying eggs. According to scientists, this plug formation associated with the rejection of sex. Female spiders do not want excessive sex.
