Corn Flea Beetle
A very small, shiny black to bronze flea beetle with a compact, oval body. It vectors Stewart's wilt bacterium, making it both a direct and indirect pest of sweet corn.
Did You Know?
The severity of Stewart's wilt in a given year can be predicted by winter temperatures, since cold winters reduce overwintering beetle populations.
African Coconut Rhinoceros Beetle
A robust, dark chestnut-brown beetle with a single curved horn on the male's head. It is a significant pest of coconut and oil palm plantations along the East African coast.
Did You Know?
Adults are primarily active at night and are strongly attracted to lights, which is used as a basis for light-trap monitoring programs.
