Do Bed Bugs Need a Male and Female to Reproduce?
In order to reproduce, bed bugs need a male and a female to mate. The female has an ovipositor, a tubular organ, and the male injects sperm into the female’s hemocoel. The sperm then travels through the female’s body and fertilizes her eggs. The female bedbug also has a special organ called the spermalege, which is found on her right side.
A male bedbug prefers a female that is freshly fed. This allows the male to penetrate the female’s outer shell easier. Once the male has pierced the female’s skin, he will fertilize her and leave her feeling nervous. The female then feeds herself during the egg carrying phase, enabling her to lay more eggs.
It is important to note that a female bedbug can lay three to five eggs per day. Under ideal conditions, the population of bedbugs can double every 16 days. The eggs will hatch at seven to ten days, depending on the temperature. When temperatures are lowered, the eggs will take longer to hatch.
The reason for this behavior is unclear. Scientists are still studying the mechanism that bedbugs use to control the reproduction cycle. However, they do know that the bedbugs use alarm pheromones to discourage prowling males. This is not beneficial for the bedbug population, and researchers hope to develop a way to limit male mating.
