What did the Hawaiians do to get rid of cane toads (aside from sending them to us)?
It so happened that I worked, in 1968, with a bloke who introduced cane toads to the Pacific. A Guatemalan by birth, he moved to the U.S. (Hawaii) when he was 13 and was soon a real dinki-di American. However, his first job (with the U.S. Department of Agriculture) years later was to go back to his home in Guatemala and carefully collect some specimens of Bufo marinas and ship them back (with him) to Hawaii, in what turned out to be a failed attempt at controlling the cane beetle. As we know, this early biological control attempt failed, and the cane toad is not only still in Hawaii but in most of the rest of the Pacific.
