Biology and ecology

2. A female dryinid wasp lives for 6 to 7 days. It can eat 2 to 4 hoppers a day. Likewise, it can also parasitize 4 to 6 hosts a day.
3. It lays one or two eggs inside the hopper host and egg incubation is 1-2 days. During larval development, it feeds on the host’s body fluid.
4. It protrudes from the abdomen of its host as a black to grayish sac. After 7 to 10 days, the larval sac splits to expose a whitish larva.
5. Pupation occurs outside the host’s body. It secretes a whitish oval silk cocoon to cover the pupa. Before to adult emergence, the flat cocoon turns reddish brown.
