| Sumario: | The survey of fruit fly species, especially of the Tephritidae family, in the culture of chili peppers (Capsicum frutescens) is important for a better understanding in the monitoring and control of these groups of insects, given their economic importance for the production of chili peppers. Fruit flies are responsible for major losses in commercial fruit trees, so it is essential to know the predominant species in the region. The objective of this work was to study the influence of fruit flies (Diptera: Tephritidae) on the cultivation of chilli pepper in the Mozambican semi-arid region. Infested ripe fruits (with larvae and/or with symptoms of fruit fly attack) were systematically selected, 1 fruit was collected fromeach plant, targeting damaged and undamaged fruits on each plant. it was necessary to distribute traps in the area and subsequently collect the flies. The obtained results indicate that in the monitoring with traps there was a predominance of the genus Dacus in relation to the genus Ceratitis. The population peaks of each season (2013 and 2014) occur in the second semester in months of fruit maturation in all genera. The occurrence of species such as: Celidodacus sp., Ceratitis capitata, C. cosyra, C. millicentae, C. rosa, Dacus sp., Dacus bivittatus, D. famona, D. hamatus, D. humeralis, D. punctatifrons. In conclusion, the attack of fruit flies significantly influenced productivity, causing economic damage, requiring redoubled control. The sequential use of the toxic bait, over time, increased the number of populations of the genera Ceratitisand Dacus. The application of traps was not able to prevent the access of fruit flies within the production areas. |
