Purple Loosestrife Beetle
A small, yellowish-brown beetle deliberately introduced as a biocontrol agent against invasive purple loosestrife. Adults and larvae feed on leaves and growing tips of the target weed.
Did You Know?
This beetle has been one of the most successful classical biological control agents, dramatically reducing purple loosestrife infestations across North America.
Spotted Stem Borer
A straw-colored moth whose larvae bore into stems of maize and sorghum in Africa and Asia. It can cause total crop failure in heavily infested fields.
Did You Know?
The push-pull pest management system, using Desmodium and Napier grass, was developed primarily to combat this borer.
