“…A associação da meleira e moscas-das-frutas foi também observada por Nascimento et al (2000) Em coletas realizadas no norte de Minas Gerais ainda não tinha sido constata a ocorrência de C. capitata em frutos de mamão. Esta espécie ocorre predominantemente em pomares domésticos da zona urbana enquanto que as espécies de Anastrepha predominam em pomares comerciais da região (Alvarenga et al 2000).…”

“…The eggs were then inserted into the host fruits (guavas or mangoes) in cavities (1.5 cm deep) previously prepared using a scalpel. Ten eggs of the same species were placed at the bottom of each cavity (five cavities per guava and 10 cavities per mango), and the cavities were then closed off with the same superficial fragment removed earlier from the fruit, and sealed with melted paraffin (Nascimento et al., 2000). In the Obl + Frat treatment with guavas, four cavities had ten eggs of the same species (two cavities with A. obliqua eggs and two cavities with A. fraterculus eggs) and only one cavity had 5 eggs of each species, reaching a total of 25 eggs of each species.…”

Interspecific competition between individuals of different species can result in reductions in their fecundity, growth or survival, reflecting differential exploitation of resources that become intensified due to spatial co‐occurrence, ecological similarity and increased population densities. As two species cannot occupy the same niche, coexistence is only possible if the available resources are used in non‐overlapping manners such as niche partitioning or the use of refuges. Among agricultural insect pests, such as fruit flies of the family Tephritidae, competitive interactions can result in competitive displacement, host changes, or the expansion or restriction of the numbers of hosts utilized that can have negative consequences for human agricultural activities. We evaluated the competitive interactions between two fruit fly species of the genus Anastrepha, Anastrepha obliqua (Macquart, 1835) and Anastrepha fraterculus (Wiedmann, 1830), on their respective preferred hosts (mangoes and guava). Experiments of larval competition and competition for ovipositioning sites by adult females were performed to compare the parameters of larval development time, numbers of pupae and emerged adults and numbers of ovipositions in the presence or absence of interspecific competition. We observed that the interactions between those species were asymmetrical and hierarchical, and our results suggest a competitive displacement of A. fraterculus by A. obliqua when those two species are present on the same fruit, whether mangoes or guavas.

“…To be precise, eggs were placed in 1.5 cm deep cavities (10 eggs from a single species per cavity), which had been previously cut into the fruits using a scalpel. Following their inoculation with 10 eggs from a single species, each cavity was closed with the fruit fragment that had been previously removed and sealed with melted wax (following Nascimento et al ., 2000). The number of cavities in a single fruit varied depending on the total number of eggs inoculated in it.…”

We examined the competitive interactions between a native fruit fly species (Anastrepha obliqua Macquart) and the invasive medfly (Ceratitis capitata Wiedemann) when these co-occur on a shared mango fruit host (Mangifera indica L.). 2 Using mango fruits of distinct levels of ripeness, we investigated both competition among larvae and among adult females for oviposition. We quantified competition by the numbers of eggs laid and the intensity of agonistic interactions between adult females. 3 Interactions between immature fruit flies led to reduced size and number of emerged adults of both species. These impacts were felt more acutely in the native species. 4 Interspecific competition between females led to fewer eggs laid on semi-ripe fruit by both species, which may be the result of niche overlap associated with oviposition. 5 Intraspecific interactions between A. obliqua individuals led to intense agonistic behaviour, with a concurrent decrease in number of landings on these host fruits. 6 These results suggest that the native species undergoes a partial niche displacement when facing the invasive species. A portion of the fundamental niche of A. obliqua remained unoccupied by the invading C. capitata, which may allow their coexistence under natural conditions.
