<P> The cane toad was introduced into Fiji to combat insects that infested sugarcane plantations . The introduction of the cane toad to the region was first suggested in 1933, following the successes in Puerto Rico and Hawaii . After considering the possible side effects, the national government of Fiji decided to release the toad in 1953, and 67 specimens were subsequently imported from Hawaii . Once the toads were established, a 1963 study concluded, as the toad's diet included both harmful and beneficial invertebrates, it was considered "economically neutral". Today, the cane toad can be found on all major islands in Fiji, although they tend to be smaller than their counterparts in other regions . </P> <P> The cane toad was introduced into New Guinea to control the hawk moth larvae eating sweet potato crops . The first release occurred in 1937 using toads imported from Hawaii, with a second release the same year using specimens from the Australian mainland . Evidence suggests a third release in 1938, consisting of toads being used for human pregnancy tests--many species of toad were found to be effective for this task, and were employed for about 20 years after the discovery was announced in 1948 . Initial reports argued the toads were effective in reducing the levels of cutworms and sweet potato yields were thought to be improving . As a result, these first releases were followed by further distributions across much of the region, although their effectiveness on other crops, such as cabbages, has been questioned; when the toads were released at Wau, the cabbages provided insufficient shelter and the toads rapidly left the immediate area for the superior shelter offered by the forest . A similar situation had previously arisen in the Australian cane fields, but this experience was either unknown or ignored in New Guinea . The cane toad has since become abundant in rural and urban areas . </P> <P> The cane toad naturally exists in South Texas, but attempts (both deliberate and accidental) have been made to introduce the species to other parts of the country . These include introductions to Florida and to the islands of Hawaii, as well as largely unsuccessful introductions to Louisiana . </P> <P> Initial releases into Florida failed . Attempted introductions before 1936 and 1944, intended to control sugarcane pests, were unsuccessful as the toads failed to proliferate . Later attempts failed in the same way . However, the toad gained a foothold in the state after an accidental release by an importer at Miami International Airport in 1957, and deliberate releases by animal dealers in 1963 and 1964 established the toad in other parts of Florida . Today, the cane toad is well established in the state, from the Keys to north of Tampa, and they are gradually extending further northward . In Florida, the toad is a regarded as a threat to native species and pets; so much so, the Florida Fish and Wildlife Conservation Commission recommends residents kill them . </P>
