Add Tag | Summary: | In this research species of fruit fly present in the canton Paltas in the province of Loja were recorded and monitored and their population dynamics observed over a six month period. 17 McPhail traps and 17 Jackson traps were set up to catch adult flies in the fruit growing areas of San Antonio, Yamana, Casanga and Guachanama. To complete the investigation sampling was also conducted on fruit crop hosts to this pest. The traps were checked every seven days during the study period and the specimens collected were counted and identified by gender, in the laboratory of entomology at Agrocalidad-Loja. The sampling was carried out during the months of February and March on fruit collected from the plant and ground, whose selection and the dissection was performed in the laboratory of entomology. The recovery of adult flies was carried out on the boxes of ripening fruit with sand substrate. Throughout the sampling of fruit, it was determined that Mangifera indica and Spondias purpurea were host to Anastrepha fraterculus, and Anastrepha striata Psidium guajava provided 31 specimens. Three kinds of fruit fly were captured: Anastrepha spp, which presented a greater number of species Anastrepha striata, Anastrepha distincta, Anastrepha serpentina, Anastrepha grandis, Anastrepha obliqua, Anastrepha mucronota, Anastrepha macrura, Ceratitis capitata and Toxotrypana recurcauda thus providing 8962 males and females specimens. The highest number of FTD (Fly Trap Day) captured in McPhail traps were 5136 for A. fraterculus, 1707 for A. obliqua, and 1004 for C. capitata during the months of February and March, which coincided with the stages of ripening and harvesting of fruit. According to the results obtained from the monitoring, it could be seen that the area of the Canton of Paltas was within the range of the highest density between 51% - 100%: comprising of a quantity of specimens so great that it would be virtually impossible to obtain healthy fruit and thus rendering the region virtually inappropriate for growing fruit. |
