On web for bedbug last week an article on the reproductive life of the bedbug caught my eye. There are some inconsistencies in the original article but the fundamental facts were fascinating enough. Could it be at long last our trusty foe can actually contribute some good valueto society?

Bedbugs thrive thanks to our busy lifestyles in warm heated homes and what is fascinating is that the females have developed immune structures inside their bodies, because of the aggressive sexual techniques used by the males, which are equipped with knife-like penises that they wield like knifes . Instead of availing themselves of the female reproductive structures the male bedbugs simply stab the females in the abdomen and inject sperm directly into the abdominal cavity. The sperm travels through the female's body to fertilise her .

Females suffer a 25 per cent higher death rate than males because of infections introduced into the wounds during this violent mating. Females mate only after feeding with blood as they are so engorged, their abdomens having swelled by up to 30 per cent, that they cannot escape. This is a peculiar reproductive system and is so extreme it seems to have only evolved once. Bedbugs look like small brown moving dots and often live in unclean spaces, often crawling through faeces. However remember they can also live in very clean houses as well. Lifestyle is no barrier to bedbugs . Males and females are covered in bacteria and fungi and the males introduce these germs into the female when they mate. The higher female death rate isn't caused by the wounding, it's the germs . Females have responded to this by developing a whole new immune structure to help protect them against infections introduced by this unusual sexual behavior.

This unique structure could help in the battle against malaria which is on the increase worldwide due to global warming. This organ forms a storage pool of white blood cells (which fight infection acting as a first line of defence against potential sexually transmitted infections. This unique structure has developed over the main area targeted by the mail bedbu during sex.

Immune structures like this are found nowhere else in the animal world and their discovery should eventually help scientists to develop new techniques to stop mosquitoes passing malaria and other fatal diseases to people.

Professor Mike Siva-Jothy, of the University of Sheffield, was one of the main scientists involved in the discovery of the structure , which he said will allow researchers to study a concentrated form of insect immune systems. In other insects immunity is spread throughout the body. 'It's important for understanding how insects fight disease .

This may well lead to some exciting discoveries in the future, however some reality needs to be brought to the table as was commented on various sites on the internet. Remember that when you think about this in detail the only trouble with even engineering such a solution is that it would be necessary first to manipulate some malaria mosquitoes (Anopheles) to have such an immune system (rocket science at best at the present time). Vaccinating mosquitoes? And then the little matter of breeding and replacing all malaria-carrying mosquitoes on the planet with them. If we could replace whole populations of mosquitoes in the wild like that, we would have eradicated malaria long ago!

Malaria is caused by a single-celled organism , Plasmodium, with an incredibly complicated life cycle. A minor part of this life cycle takes place in the mosquito. Bedbug females are, after their rape, threatened mainly by bacteria and fungi, very simple organisms compared to Plasmodium. Of course any information the research can provide is interesting, but it has all been hyped and connected just a little too much here. However I did still find the report fascinating and will keep this research under the microscope over the years ahead and make sure banish bed bugs is aware of any further advances.
