Distribution and population characteristics of tephritid flies, namely, solana- ceous fruit fly, Bactrocera latifrons Hendel, oriental fruit fly, B. dorsalis (Hendel), melon fly, B. cucurbitae (Coquillet), and Mediterranean fruit fly, Ceratitis capitata (Wiedemann) were monitored with male lure traps on Kalaupapa peninsula on the island of Molokai. Likewise, fruits were inventoried and sampled to augment trap data and generate information

Biological control has been the most commonly researched control tactic within fruit fly management programs. For the first time, a review is carried out covering parasitoids and predators of fruit flies (Tephritidae) from the Americas and Hawaii, presenting the main biological control programs in this region. In this work, 31 species of fruit flies of economic importance are considered in the genera Anastrepha (11), Rhagoletis (14), Bactrocera (4), Ceratitis (1), and Zeugodacus (1). In this study, a total of 79 parasitoid species of fruit flies of economic importance are listed and, from these, 50 are native and 29 are introduced. A total of 56 species of fruit fly predators occur in the Americas and Hawaii.
Fopius ceratitivorus Wharton is the most recently imported parasitoid for biological control of tephritid fruit flies in Hawaii. In this paper we summarize current progress on studies of this parasitoid under quarantine conditions in Hawaii. Tests on its potential target host range reveal that F. ceratitivorus attacks and completes its development only in the Mediterranean fruit fly, Ceratitis capitata (Wiedemann). The three other extant fruit fly pests in Hawaii, Bactrocera cucurbitae (Coquillett), Bactrocera dorsalis (Hendel) and Bactrocera latifrons (Hendel) are unsuitable for F. ceratitivorus development. Competition studies with the well-established and dominant fruit fly parasitoid, Fopius arisanus (Sonan), showed that either species can win in intrinsic competition with each other, depending on which one occupies the host first. In both choice and no-choice tests, F. ceratitivorus was found to cause no parasitism nor mortality to eggs or larvae of the non-target tephritid Procecidochares alani Steyskal on infested pamakani weed, Ageratina riparia (Regel); nor the native Hawaiian tephritid Trupanea dubautia (Bryan) infesting flower heads of the endemic Asteraceae shrub, Dubautia raillardiodes Hillebrand. These findings suggest that release of this parasitoid as a biological control agent in Hawaii will pose minimal non-target risk and may contribute to overall fruit fly biological control in the islands. The delays due to the regulatory bureaucracy in removing the wasp from quarantine following host range testing are also discussed.
The Hawaii fruit fly areawide pest management programme
Areawide pest management: theory and implementation, 2008
This chaper describes the areawide pest management (AWPM) programme for the Hawaii fruit fly (Diptera: Tephritidae). The programme included developing and integrating biologically based pest technology into a comprehensive IPM package that was economically viable, environmentally friendly and sustainable. It included operational, research, education and assessment components. The technologies included (i) field sanitation; (ii) application of protein bait sprays; (iii) male and female annihilation with male lures and other attractants; (iv) sterile insect releases; and (v) conservation or release of beneficial parasitoids. The development and implementation of education and technology transfer programmes are discussed for the success of the AWPM programme. The implementation of the AWPM programme and its compatibility with crop management and management of co-occurring pests; efficacy at controlling the target pest; unintended negative and positive consequences; sociological evaluat...

The Vector Control Branch of the Hawaii State Department of Health has accumulated a large volume of written inspection data on pests of public health for the island of Oahu. Fly related problems, excluding both mosquitoes and odor complaints that often lead to fly breeding violations, provided the second greatest amount of arthropod pest information available, after mosquitoes. The objectives of this study were to conduct a survey on the occurrence of fly complaints on Oahu over a 10 year period, determine their distribution over time, graphically compare fly occurrence within and between district/areas, and correlate fly occurrence and distribution with season. Fly data were drawn from inspection reports from 1990-1999, population information was obtained from Hawaii Census and State of Hawaii Data Books, 125 district/area geographic locations were defined, and fly occurrence and distribution were adjusted for population and mapped using ArcView GIS 3.2. Overall, reported fly activity was found to occur fairly evenly across the island's districts. Lower elevation areas around the perimeter of Oahu had the greatest number of complaints and the levels of fly activity were highest during the winter and summer. The primary fly species recorded were Phaencia cuprina (Wiedemann), the bronze bottle fly; Musca sorbens Wiedemann, the dog dung fly; Chrysomya megacephala (Fabricius), the Oriental blow fly; and M. domestica Linneaus, the house fly. The main breeding sources were food garbage and slop, pet and farm animal dung, dead animals, and rotten fruits. Fly populations are being maintained in urban and agricultural districts by human activities. As a result, disease transmission is possible, especially in the lower elevation, urban and agricultural areas of Oahu. These results indicate that educational programs should be carried out in late fall and late spring, and that residential fly surveys may be concentrated in a limited number of district/areas.

Fruit flies (Diptera: Tephritidae) are major pests of fruits and vegetables in many countries, including Indonesia. Knowledge of the fruit fly host range in a specific area is an important part of the area-wide pest management program to reduce the pest problem. The aim of this study was to extend and update the information on the host range of fruit flies in the Regency of Sleman, Yogyakarta. This area is one of the centers of fruit production, particularly snake fruit in Indonesia. Fruit sampling was conducted from August 2019 to February 2020 in four sub-districts in Sleman consisting of different types of agro-ecosystems. Fruit rearing was carried out in the laboratory followed by identification of the fruit and fruit flies that emerged to species level. From the 23 species of fruits belonging to 14 different families that were collected, the following 6 species of fruit flies emerged: Bactrocera dorsalis, B. carambolae, B. umbrosa, B. albistrigata, B. mcgregori, and Zeugodacus ...
