The fruit fly Bactrocera dorsalis, an insect belonging to the Tephritidae family, causes enormous damage to fruits and attacks several host plants to maintain its population. Quarantined species, it causes significant economic losses and could intervene in environmental pollution due to polyphagia morphological adaptation and a rapid orchard reinfestation. The objective of this study is to morphometrically characterize B. dorsalis from different host plants. Methodology and results: sampling is done in three localities in the Niayes area in Senegal in several orchards. Three populations were defined according to the host fruits (mango, mandarin and cashew apple). Each population consists of 30 young fasting males born within 24 hours. The number of variables measured for morphometry on each individual is 35. Of the eight head variables, only the thickness of the head (EpTe) and the length of the antenna (An) show significant differences. There is a significant difference on all ten chest variables except chest length (Th) and lateral spot thickness (EpTaLa). There is no significant difference for the size (Tai) which is not the case for the length and the thickness of the abdomen (Ab and EpAb) of the 3 populations. The variables of the front leg show a significant difference as well as those of the hind leg except the tarsus 1 (PPT1). The middle leg shows only a significant difference in the variable representing tarsi 2, 3, 4 and 5 (PMTS). Ultimately, the population of B. dorsalis from the cashew apple is morphometrically closer to that from the mango while the population from the mandarin is morphometrically different of that from the cashew apple.
