Infestation rate of Mangifera indica fruit fly in Sudanese zone of Mali

Abstract

Mali has a potential for mango production across the country. However, this plant is facing phytosanitary problems mainly related to fruit flies. The study was conducted to evaluate the infestation rate of fruit flies on mango varieties in Sudanese zone of Mali (Kati). Stung mangoes were weekly collected from three sites. Fruits were weighted and placed inside plastic bags containing sand to the monitor larva infestation under semi-natural conditions within of the laboratory. Bactrocera dorsalis and Ceratitis cosyra were the two species identified from all sites with an average of 22.88 and 23.32 fruit flies, respectively. C. cosyra appreciated mango varieties such as Valencia, Amelie, Kent, Davis Haden and Keitt whilst B. dorsalis preferred Keitt, Brooks, Kent and Smith varieties. No correlation was found between mangoes weight and the number of emerged flies in addition to lack of sex predominance based on fruit' fly species. The infestation rate varies according to the variety of mangoes.

“…The shade of grown trees can also protect against excessive sun exposure and create the ideal temperature and humidity for fruit flies. Rahinatou et al (2020) suggested that the temperature and humidity play a role in fruit fly populations, when the temperature drops (below 30°) in increasing humidity (greater than 70%), the population of C. cosyra decreases, whereas B. dorsalis increases. Meanwhile, according to Raghuvanshi et al (2012), the temperature played a specific role in regulating the behavior of the fruit fly adults, which indicates the positive correlation of prevailing temperature with the number of ovipositing females; thus, the influence of relative humidity and rainfall harmed female abundance.…”

Dominance of Bactrocera dorsalis Hendel on Ceratitis cosyra Walker (Diptera: Tephritidae) in orchards in Bujumbura, Burundi

“…During the dry season, fruits were not available, contributing to very low captures. In fact, fruit availability corresponding to months and phenology stages has an influence on the population fluctuations of fruit flies (Rahinatou et al, 2020).…”

“…The difference in abundance for the two species would be due to mango varieties within the orchards. In Mali,Rahinatou et al (2020) concluded that the preference on mango varieties were different for the two species. B. dorsalis preferred Keitt, Brooks and Smith varieties whereas C. cosyra preferred Valencia, Amelie and Davis…”
