Methyl eugenol is an extremely effective attractant for male oriental fruit flies, Bactrocera dorsalis (Hendel). Field experiments were conducted in a commercial guava orchard to determine whether the presence of methyl eugenol-baited traps affected the distribution and abundance of female oriental fruit flies near the traps. Captures of females on spheres did not increase within the vicinity of methyl eugenol-baited traps. Captures of males were significantly greater on spheres hung in trees containing methyl eugenol-baited traps than on spheres hung in other trees. An experiment was conducted to determine if methyl eugenol would influence the dispersal of unmated, sexually mature female oriental fruit flies. There were no significant differences in the numbers of marked or wild females captured on traps at different distances from the methyl eugenol lure. This study did not find any evidence that the presence of methyl eugenol-baited traps in orchards would affect female abundance in the vicinity of traps.

Mango (Mangifera indica L.) is an important fruit crop in Nigeria. It is a source of essential vitamins and is also cultivated for its nutritional, medicinal and industrial uses. Fruit flies infest various commercial fruit crops and cause economic damage. Mass trapping and male annihilation technique (MAT) has been the most useful and common means of controlling fruit flies with special focus on Bactrocera dorsalis Hendel (Diptera: Tephritidae) on mangoes. The study evaluated the effectiveness of four types of parapheromones namely, methyl eugenol (liquid and solid forms), cuelure, terpinyl acetate and trimedlure for mass trapping of fruit flies on Mango. Modified Lynfield traps containing the parapheromones were randomly set on the mango orchards in three replicates in Nigeria Horticultural Research Institute (NIHORT) orchard, Okigwe, Imo state, Southeast Nigeria. This study was conducted during the mango fruiting period of 2019 season, when the density of fruit flies peaked. Effect of parapheromones on mean number of damaged dropped fruits was also evaluated. The mean population of B. dorsalis and Ceratitis cosyra was significantly higher (P>0.05) in liquid methyl eugenol traps when compared to other parapheromones. Bactrocera dorsalis recorded more than 90% of the fruit flies that were trapped especially in the first 3 weeks of trapping. In orchard I, Liquid methyl eugenol significantly (P<0.05) trapped highest number of B. dorsalis (270.20) in week I and similar trends were observed in orchard II. There was steady decline in damaged dropped mango fruits as the study progressed (Fig. 1 and 2). Use of liquid methyl eugenol was most effective in trapping B. dorsalis and C. cosyra, and it can be incorporated in Integrated Pest Management (IPM) programmes for the control of fruit flies.

Fruit fly (Bactrocera dorsalis Complex) is one of the major pests in horticultural commodities in Indonesia. In this present study, a control method of formulating methyl eugenol and the addition of fruit essences was tested to attract B. dorsalis Complex. The objective was to find out the effect of fruit essences addition in the performance of methyl eugenol in attracting fruit flies and to obtain the most effective fruit essences for attracting male and female fruit flies. The experiment was conducted on mango plantation in Pasirmuncang village, Majalengka, West Java from March 2016 until December 2016. Several synthetic fruit essences which were separately added to methyl eugenol in this experiment were mango, citrus, guava, and starfruit essences. The results showed that the addition of fruit essences on methyl eugenol traps had the same effectiveness  or as good as  any single methyl eugenol trap. Moreover, the additions of mango and orange essences  were not effective enough in attracting female fruit flies, although the number of female fruit flies that were caught were more than the other treatments. IntisariLalat buah Bactrocera dorsalis Kompleks merupakan salah satu hama utama pada komoditas hortikultura. Pada penelitian ini, metode pengendalian dengan memformulasikan metil eugenol dan tambahan esens buah diuji untuk menarik B. dorsalis Kompleks. Tujuannya adalah untuk mengetahui efek penambahan esens buah pada kinerja perangkap metil eugenol dalam menarik lalat buah serta untuk mendapatkan esens buah yang efektif untuk menarik lalat buah betina. Penelitian ini dilakukan di perkebunan mangga di desa Pasirmuncang, Majalengka, Jawa Barat dari bulan Maret 2016 hingga bulan Desember 2016. Beberapa jenis esens buah sintetik yang secara terpisah ditambahkan pada metil eugenol pada percobaan ini adalah mangga, jeruk, jambu biji, dan belimbing. Hasil penelitian menunjukkan bahwa penambahan esens buah pada perangkap metil eugenol memiliki keefektifan yang sama baiknya dengan perangkap metil eugenol secara tunggal. Selain itu, penambahan esens mangga dan esens jeruk belum cukup efektif dalam menarik lalat buah betina meskipun jumlah lalat buah betina yang tertangkap lebih banyak dibandingkan dengan perlakuan lainnya.

A community-based area wide fruit fly suppression exercise involving simultaneous application by farmers of methyl eugenol-mediated mass capture of males of Bactrocera dorsalis fruit fly, crop sanitation by burial of fallen fruits and SUCCESS bait (GF 121)spot application of citrus tree crowns, was undertaken in three villages in Muheza district, Tanga region north eastern Tanzania. Male fruit fly numbers in methyl eugenol traps dropped significantly following application of the treatments from 970 flies per trap per week before application of treatments in July 2011 to 100 and 46 flies six and nine months after treatments at Kwabada village; 200 flies per trap per week before to 34 and one flies after treatment at Kwemsaa village and from 800 flies before to 64 and 50 flies per trap per week during the same period at Mlingano village. However, a fall occurred also in untreated orchards indicating a possible spill-over effect of the treatments due to the large area covered. Moreover, the treated areas might have acted as a sink that drew fruit flies from neighbouring untreated orchards into it. The drastic fall in trapped males may be associated with the effect of the treatments in reducing the number of flies so that fewer were available to fly into the traps. The collective and simultaneous application by farmers of fruit fly suppression over a large crop area is a robust strategy to manage fruit flies in citrus and other fruits orchards such as mango. The results suggest that farmers can successfully implement area-wide fruit fly suppression in smallholder citrus systems.
