Context
Chelonus (Carinichelonus) mahadeb, a rare parasitic wasp, has been newly recorded at the Nahortoli Tea Estate in Assam. This is significant as the subgenus Carinichelonus is extremely rare and poorly documented worldwide, making it only the 2nd new species reported from India in recent years.
Q1. What is Chelonus (Carinichelonus) mahadeb?
It is a newly identified species of parasitic wasp belonging to the genus Chelonus.
Q2. How do parasitic wasps of the genus Chelonus function?
- These wasps are very small insects but have an important ecological role.
- They are known as egg–larval parasitoids. The female wasp lays its eggs inside the eggs of other insects, usually moths and butterflies.
- When the wasp larva develops, it feeds on and eventually consumes the host insect, completing its life cycle.
Q3. Why are these wasps ecologically important?
- Many moth larvae are serious agricultural pests that damage crops.
- By parasitising these insects, species of Chelonus naturally control pest populations.
- Therefore, they are considered beneficial insects that support natural pest management in agricultural ecosystems, including plantations.
