A tiny encyrtid wasp credited with saving Africa's cassava crop from devastating mealybug infestations. It was introduced from South America in the 1980s as a biological control agent.

💡

Did You Know?

Its release across Africa is considered one of the most successful biological control programs in history, saving millions from famine.

Spruce Gall Adelgid

A tiny woolly aphid-like insect that induces distinctive pineapple-shaped galls on Norway spruce twigs. The galls form when the insect's feeding causes abnormal growth of developing needles.

💡

Did You Know?

The pineapple-shaped galls are formed by modified needles that swell and fuse together, creating chambers in which the adelgid nymphs develop protected from the environment.
