parasitoid wasps

Wasps lay eggs using ovipostor, says IISc study

New Zealand scientist names a newly discovered species of wasp Lusius malfoyi after the Harry Potter baddie Lucius Malfoy in hopes to bring awareness about the species.

Indian scientists at ZSI have pioneered a groundbreaking method using DNA metabarcoding to decode spider-parasitoid relationships directly from egg sacs. This innovative approach, published in Scientific Reports, identified elusive parasitoid genera and unveiled hidden ecological connections. The research significantly contributes to biodiversity conservation and ecological understanding by making previously invisible interactions visible.

A unique parasitic wasp from 99 million years ago, preserved in Cretaceous period amber, featured a Venus flytrap-like structure on its abdomen. This structure likely allowed the wasp, named Sirenobethylus charybdis, to trap insects to shelter its larvae, showcasing a previously unseen evolutionary trait among insects.

Wasps are largely misunderstood insects, playing vital roles as pollinators, predators, and scavengers, far beyond their reputation for stinging. They are crucial for biological pest control, significantly reducing the need for harmful chemical pesticides by preying on crop pests. Scientists highlight their ecological importance and fascinating behaviors, urging a reevaluation of their image.

District agriculture officials on Tuesday urged coconut farmers to check their trees frequently as infestation of black headed caterpillars was found in coconut farms spread over three acres at Pathuvampalli near Karumathampatti.
