Abstrakt: The decrease of lifespan by mating is a common, yet poorly understood occurrence. Juvenile hormone (JH) is widely believed to mediate shortened lifespan in insect, caused by mating. In this study we tested the role of JH in the linden bug (Pyrrhocoris apterus) by removal of the corpus allatum gland and thus the JH source. We then proceeded to study the lifespan of mated animals vs. virgin animals. Virgin animals without JH live longer as was expected. The effect on mated animals is however different between males and females. Surprisingly in females, JH seems to lower the cost of mating. In males, on the other hand, the cost of mating seems to be independent on JH levels. Another surprising conclusion is that the level of JH in females affects the lifespan of males that mate with such females.
