Coconut Rhinoceros Beetle
A major pest of coconut palms across tropical Asia with a single prominent horn. Adults bore into the crown of palms, causing severe damage to fronds.

A biological control virus called Oryctes rhinoceros nudivirus has been successfully used to manage this pest.
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.
