Genome of the bed bug explains insecticide resistance and brutal sex

 Beg bug infestations have grown since the 1900s with heated homes and air travel. Insecticides that were developed in the mid-1900s kept them at bay for a while but, by the 1990s, the bed bug had found ways to avoid or detoxify them and spread again rapidly. The secrets behind the bed bug’s success can be found in its genome which was recently sequenced by researchers.
The scientists discovered amongst other findings in the bed bug genome genes that seem to be of bacterial origin and were acquired over many years. These foreign bacterial genes may help the bed bugs digest human blood and have given the bug’s genome a unique profile.
The scientists also found out that a bed bug needs to ingest human blood before defence mechanisms are actually activated to make it resistant to toxins. These new findings might serve as an approach to develop an insecticide ultimately capable of fighting off the bugs.
The scientists also discovered that the protein resilin protects the females during the brutal act of reproduction: The male bugs mate by piercing the abdomen of their female counterparts and injecting their sperm.
