The mango fruit fly (Ceratitis cosyra Walker) is the major pest of economic importance and which restricts mango exports from infested production areas in the SADC region. The effect of three pruning techniques, box/rectangle, spherical/round and the central leader, on assessing spatial distribution of fruit fly populations in high density mango production were investigated at Chiredzi Research station (21°01’S, 31°33’E) from 2010 to 2013. Results showed a significant rise in the number of adult fly catches among pruning techniques as from July to December (p< 0.05). Traps baited with Malathion 25% WP with molasses as an attractant were used to trap the flies. Results from all treatments indicated a significant rise in mean adult fruit fly catches from the months of July to December. It can be concluded that spatial distribution of the mango fruit fly is influenced by the fruiting and ripening patterns of mango.

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.

Abstract Embam (Mangifera odorata) is one of mango species (Mangifera spp.) which has a typical aroma. Some species of fruit flies are more interested in laying eggs on mango fruit compared to other fruits. It does not rule out the possibility that some insect species use fruit which falling to laying eggs or as a food source. Need a research to be done about the potential of falling fruit to support insects survival. This research was conducted in November 2018 by observing of falling embam fruit under the tree to see what insects contained in the fruit and analyze the benefits for these insects. Found 6 insects species from a total of 6 families and 2 order on embam fruit which falling. Insect species of order Diptera are most commonly found with a total of 5 species from 5 families. Insect species from order Hymenoptera found only 1 species. The difference on embam fruit ripeity and condition of embam fruit affects insects species which found. on a ripe embam fruit can be useful as a food source for insects, while in rotten embam fruit can be beneficial for insects to laying eggs.

The species diversity of tephritid fruit flies in major mango-growing regions in Uganda was monitored over a 2-year period (2010–2012) using fruit bait and lure traps. A total of 368,332 specimens belonging to 10 species in four genera (Bactrocera,Ceratitis,TrirhithrumandDacus) were collected. Of these, 98.9% belonged toBactrocera invadens, while the second and third most common species wereDacus bivittatus(0.4%) andCeratitis anonae(0.3%), respectively. Significant differences in the evenness and diversity of fruit fly species were noted across the regions. Fruit fly community structure was significantly different across the three regions. The Lake Victoria Crescent and Mbale Farmlands harboured significantly moreD. ciliatus,T. coffeae,D. bivittatusandB. cucurbitaein contrast to the Northern Moist Farmlands and the Western Medium High Farmlands.Ceratitis rosacontributed the highest difference in regional structure, followed byC. fasciventrisandC. cosyra. Rank abundance curves depicted a geometric series distribution of the species composition in the three regions, confirming a scenario of competitive displacement of native fruit fly species byB. invadens. A comprehensive and sustainable response strategy toB. invadensand other fruit flies needs to be urgently devised to protect the horticulture industry in Uganda.

AbstractBactrocera invadens, a fruit fly from Asia, is an invasive pest species across Africa. It appears to continue spreading, not only in latitude but also in altitude. To assess its capacity to infest a large variety of hosts and its competition with other fruit fly species, a study along an altitudinal gradient was conducted. At low altitudes, the high abundance in the field and high infestation of B. invadens in different fruit species make it a serious pest. At high altitudes, colonization has started and B. invadens occurs in low numbers by reproducing successfully in high altitude fruits. Overall the abundance and infestation of B. invadens is influenced by its direct competitor Ceratitis rosa and the presence of its preferred host species. C. rosa is still the dominant species in temperate fruits grown at high altitude. Ceratitis cosyra, however, is negatively affected by B. invadens, this species seems to have shifted hosts to avoid competition. The broad host range and competitive potential of B. invadens increase the risk for further spread not only to higher areas, but also to subtropical regions.
