| dc.description.abstract | On May 10, 1946, in a field collection of mangos a new species of fruit fly was discovered in Hawaii. When further investigations were made, it was evident that this fruit fly, Dacus dorsalis of the family Trephritidae, was already well established and spread throughout the islands. (Carter, 1950). It was believed to have been introduced at least a year before by the increased air travel brought on by World War II. (Van Zwaluwenbury, 1948). Dacus dorsalis caused much concern both in Hawaii and on the mainland because of the economic losses that were being suffered by the people of Hawaii and the possible damage it could bring to the orchards of California and Florida. (Armitage, 1948). Dacus dorsalis was found to have one hundred twenty-five host fruits, and larvae were found even in macadamia nuts, Vanda Miss Joaquim, and barks of certain trees when the population pressure was great. (Carter, 1950). This hardy pest thrived in warm sea level conditions but could survive at higher elevations where the temperature sometimes dropped to 32 degrees Fahrenheit to 28 degrees Fahrenheit. Dacus dorsalis were found to survive over 47 days at high elevation and they have been found to survive four months in Formosa. (Armitage, 1948). | |
