Fruit and vegetable movement on domestic flights in Papua New Guinea and the risk of spreading fruit-flies (Diptera: Tephritidae)
Putulan, David, Sar, Sim, Drew, Richard A.I., Raghu, S., & Clarke, Anthony R. (2004) Fruit and vegetable movement on domestic flights in Papua New Guinea and the risk of spreading fruit-flies (Diptera: Tephritidae). International Journal of Pest Management, 50(1), pp. 17-22.
Species of tropical fruit-flies (Diptera: Tephritidae: Dacinae) are the number one horticultural pest in the Pacific region. In Papua New Guinea (PNG), limiting the movement of fresh fruits and vegetables (= fresh commodities) between different regions within the country is one plant protection strategy that could lessen the threat posed by fruit-flies by restricting the spread of both exotic and indigenous pest species. In order to assess the risk posed by informal fruit and vegetable movement, we carried out a survey of PNG domestic airline passengers. Of 1904 passengers surveyed, 38.9% were carrying fresh commodities. Over 70 different fresh commodities were being carried, with the most common being bananas and peanuts, each being carried by over 9% of passengers. Thirty-four of these 70 commodities are known fruit-fly hosts from PNG or other countries. Sixty-three percent of passengers on flights into the National Capital District (i.e. Port Moresby) were carrying fruit, as were 74% of passengers leaving the Highland Provinces. Neither the purpose of travel nor the occupation type of a passenger influenced the likelihood of commodity carriage. Nearly all commodities came from gardens or local markets and were being carried predominantly for personal consumption or gifts. With fruit-fly infestation rates of susceptible crops being around 20%, we conclude that the risk of transport of fruit-flies is very high.
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
