The weapon of caterpillars against larvae of equestrians — viruses

The insects known as equestrians, or parazitoidny wasps, postpone eggs in young larvae of butterflies and bugs, turning caterpillars into the incubators doomed to death for hundred descendants. But some virus infections help caterpillars to fight against it. New research shows how certain viruses can help caterpillars to resist to parazitoidny wasps. Groups of proteins under the name a murder factor parazitoidov, or PKF which contain in some viruses of insects, are incredibly toxic for larvae of equestrians, scientists in the Science magazine report. According to a soavtorka...
