The Governor's gleeful Republican rivals concede that his prospects may improve if the worrisome Medfly infestation—which now threatens 20% of California's land area—can be kept clear of major growing regions through harvesttime. But entomologists are gloomy about their chances of eradicating the pest outright, as Florida and Texas officials did four times between 1929 and 1966. After the first Medflies appeared in the summer of 1980, Brown's aides estimated that the extremely prolific insect could be wiped out by cautious methods: spraying from the ground, stripping infested trees and burying the fruit, releasing sterilized flies with the fertile flies and thus upsetting the breeding cycle.
But beginning last June more than a hundred infestations were reported, almost all in recreational gardens. Farmers and Federal Government scientists, aware that one of the Medfly's favorite fruits is California's valuable orange, started to call for aerial spraying of the pesticide malathion. Brown resisted until July 10, when the Reagan Administration threatened a nationwide quarantine of California produce. Since then the pests have hit the Los Angeles area and have spread so fast that last week the territory under state watch was expanding almost daily. If the Medfly reached all plantings of every crop it infests, California farmers could lose up to $400 million, according to the U.S. Department of Agriculture. Embargoes by other states and foreign countries could cost another $500 million. If this happened, U.S. food prices could jump 2% to 4%, at least temporarily, and raise the Consumer Price Index by .25% to .5%, according to the President's Council of Economic Advisers. Already there are major costs for the California farmer. Japan, which buys $118 million in fruits and vegetables from the state, has refused to accept any California produce, though negotiations toward a compromise are under way; Taiwan, South Korea and the island of Yap have also banned California produce.
Brown has been looking for scapegoats, including a Peruvian laboratory and the U.S. Department of Agriculture. The lab apparently shipped an unknown number of flies marked "sterilized" that were in fact still fertile, and these were unwittingly released at the behest of the USDA. Last week Brown's Medfly project chief claimed that there were at least 50,000 mislabeled fertile flies, and that when released they had caused "95%" of the plague. The USDA scoffed, noting that only two fertile Peruvian flies were among the nearly 400 found in traps.
Brown remains as cocky as ever. Says he: "Where the Medfly project has taken action, the Medfly has been brought under control. The Medfly people will go out and get those flies." If he is wrong, the voters will likely tell him to buzz off.
