Levantamento sazonal de inimigos naturais de moscas-das-frutas (Diptera: Tephritidae e Lonchaeidae) em diferentes regiões e hospedeiros no Estado de Alagoas

Abstract

This study aimed to understand the diversity of natural enemies (parasitoids) of the fruit flies (Diptera: Tephritidae and Lonchaeidae) in different regions and hosts in the State of Alagoas. The experimental area was composed of six municipalities and the General Entomology Laboratory of Agricultural Sciences Center of the Federal University of Alagoas (CECA / UFAL) in Rio Largo - AL. The fields of study were divided into two distinct regions edafoclimáticamente, one of which (identified as region one) formed by three municipalities located in the Mundaú valley and the other (identified by region two) for another three municipalities of the South Coast of the state. The collection of the fruits were carried out fortnightly randomly at different times of the crown of fruit. The amount of fruits collected varies depending on the seasonality of each host species and their availability. The fruits were placed in plastic trays (54cm x 32cm) labeled with field data having a layer of a cm sieved sand and sterilized in an oven with air circulation for 48 hours at 80 ° C to serve as a substrate for pupation.The parasitoids were identified to species belonging to the Braconidae family. But others were identified to family. In Region 1 there was parasitism in pupae of six species of fruit, of which the highest percentage was observed in the fruit of iamb with 64.28%, followed by caja 59.79%, 32.12% hog plum, cherry 14, 81% with the lowest percentages white guava and red guava, being 1.36% and 0.40% respectively. Based on the observed, it is understood that the Braconidae family was the biggest incident with the species Doryctobracon areolatus (Szépligeti, 1911) being the most frequent throughout the study period, followed by the species Asobara anastrephae (Muesebeck, 1958) and Utetes anastrephae (Viereck, 1913).
