Giant Toad
The giant toad was brought here in 1932 by C.E. Pemberton to control sugarcane beetles but it was not very effective. It is a native of Mexico, Central and South America.
Wasp Egg Parasite
This Australian parasite, introduced in 1904, serves Hawai‘i by controlling the sugarcane leafhopper, a major pest. (In the ilustration, the wasp is on the right and the leafhopper it helps to control is on the left.)
Egg-sucking Bug
This Australian bug was introduced to the Islands in 1920 to control the sugarcane leafhopper. Along with the wasp egg parasite, it does a great job!
Common Mynah
Mynah birds were brought to Hawai‘i from India to control grasshoppers and armyworms. As a biological control the mynah was not successful, but it prospered in the islands and now is considered a nuisance bird.
