IntroduçãoNo Brasil, atividades agrícolas frutíferas atinge uma área de aproximadamente dois milhões de hectares, produzindo cerca de 40 milhões de toneladas de frutas frescas por ano; além disso, é um dos países com maior potencial para o crescimento da fruticultura, devido principalmente à disponibilidade de áreas e às condições edafoclimáticas favoráveis ao plantio de frutíferas (AGRIANUAL, 2014).As moscas-das-frutas pelo elevado potencial biótico, habilidade de se dispersarem no ambiente e de se adaptarem em novos hospedeiros e por causarem danos econômicos, são consideradas pragas de muitas frutíferas, principalmente em regiões com climas de tropical a temperado, o ataque das moscas-das-frutas se inicia quando o fruto se encontra verde-maduro, começando a amarelar, onde os ovos são depositados no interior dos frutos e após a eclosão, as larvas se alimentam da polpa e facilitam a entrada de organismos saprófitos, como fungos e bactérias e provocam a podridão e queda dos frutos (VIEIRA NETO, 2002).São muitos os danos provocados por esse tefritídeos, podemos destacar como perdas diretas, aquelas que ocasionam elevada diminuição da produção, queda precoce de frutos infestados, aumento do custo final de produção quando aplicado uso de defensivos agrícolas e ensacamento dos
Knowledge about the population fluctuation of fruit flies (Diptera: Tephritidae) is an important tool for control methods adoption as recommended by Integrated Pest Management (IPM). The objective of the research was to evaluate the fruit flies population fluctuation in eight domestic orchards from Paraíba swamp region and to correlate this information with the plant phenology as well as the meteorological elements. This research was developed in two rural properties of each municipality, georeferenced, identified according to fruit species diversity criterion. Adult fruit flies capture were realized by plastic traps containing 300 ml of 5.0% hydrolyzed protein aqueous solution (Bio Anastrepha®) as food attractant. Climatic data were obtained daily by thermo hygrometers and through the Executive Agency of Water Management of the State of Paraíba - AESA. During the study period, a total of 3.159 fruit flies were collected, with 10 species belonging to the genus Anastrepha and one of the genus Ceratitis. Fruit flies infestation was observed monthly for both genera, Anastrepha and Ceratitis, however, this first stood out in the whole year. The MAD (captured flies number/traps installed number/collection days number) index in a few municipalities was superior to 0.5 being recommended to do fruit flies control in these areas. The seasonal occurrences, as well as the Tephritidae infestation rates in the domestic orchards are related to the availability of fruits.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
