Resumen

The melon fly, Zeugodacus cucurbitae (Coquillett) (Diptera: Tephritidae) is one of about 250 tephrites of economic importance worldwide (Vayssiéres, 1998; Virgil et al., 2015). Native to India, and invasive in Africa, it is considered as one of the main pests that attack Cucurbitaceae (such as cucumber, watermelon, melon and pumpkin. In Mozambique, the species was first detected in 2013 in the village of Mocimboa da Praia in the province of Cabo Delgado near the border with Tanzania, and 4 individuals were identified (Cugala et al., 2013). When present in cucurbit production fields, the melon fly can cause perforations in the fruits that serve as a gateway for bacteria and fungi, deformations and premature fall of the fruits, resulting in yield losses (quality and quantity) estimated at 53 – 100% (Abro et al., 2017 and Ekesi et al., 2016 100% (De Meyer et al., 2015). The movement of cucurbit fruits from regions where Zeugodacus cucurbitae occurs is the main means of dispersal to previously infested areas, which is why, currently, the country faces an imminent threat from the dispersal of this species of fruit fly. Since 2013, no studies have been conducted to update data on the dispersal of Zeugodacus cucurbitae in the country. From May 2021 to May 2023 with support of the project on “Establishment and maintenance of free fruit production areas with low prevalence of fruit fly in Southern Africa” monitoring activities for melon fruit fly was carried out in some provinces of Mozambique The results showed that Zeugodacus cucurbitae is present in the provinces of Cabo Delgado, Niassa, Nampula, Zambezia, Tete, Manica, and Sofala with a population relatively low. The high density of the pest was found in Nampula province while the absence of the pest was found in the provinces of Maputo, Gaza, and Inhambane. As measures the suppress the pest the NPPO of Mozambique together with its partners is engaged on disseminating the management measures including the stop movement of host plants from infested areas to non-infested areas.

Peligro
According to Nasiruddin et al. (2004) the incidence of attack by the melon fly can reach high infestation rates of 88 pupae/kg to 325.3 pupae/kg of fruit in cucumber (Cucumis sativus), 179 pupae/kg to 718.25 pupae/kg in zucchini (Cucurbita pepo) and 333 pupae/kg to 681.92 pupae/kg in pumpkin (Cucurbita moschata) (Kambura, 2016 and Kambura et al., 2018 The country faces an imminent threat from the dispersal of this fruit fly species to the living zones. Z. cucurbitae is a considered quarantine pest in several countries
