Do Wasps Kill Ladybugs?
Until now, the answer to the question, “do wasps kill ladybugs?” has been a mystery. Researchers have tried to understand how wasps manipulate their host. They’ve also tried to understand the relationship between the host and the parasite.
A team led by entomologist Frederic Thomas at the Universite de Montreal is trying to answer that question. In the laboratory, they reared 4,000 ladybugs. They allowed wasps to lay their eggs inside the ladybugs. They also observed that ladybugs kept alive after the wasps were gone.
The wasps used a virus called DcPV. This virus is stored in the ovaries of the parasites. The virus transmits to the host during the larva’s development. It causes severe neuropathy in the host. Its aim is to control the parasite. The entomologist hopes that by understanding how parasites manipulate their host, they can learn more about the parasite-host relationship.
The researchers characterized the newly discovered RNA virus. RNA is short stretches of code that are used to carry out a particular task. The researchers also found RNA sequences in the ladybug’s brain.
The RNA virus is able to take over the ladybug’s nervous system. The researchers also found that the virus is able to replicate. It was not found in healthy beetles. It could also be that the beetle’s own immune system is responsible for the brain damage.
Researchers found that the ladybugs had RNA sequences that were similar to a previously unknown virus. It was able to replicate in the ladybug’s brain.
