This study aimed to evaluate the influence of the distance from the edge of native forests on the abundance of aphidophagous hoverflies in wheat fields. The study was conducted in four commercial fields in the North of Paraná State, Brazil, during the wheat crop season of 2009. Two transects were surveyed parallel to the edge of the forest at two distances: 25 (“near”) and 525 meters (“far”) from the edge. The abundance of hoverflies was compared using a χ2 test (p ≤ 0.05). In total, 1,845 hoverflies adults were collected, which represented 15 species and three genera. The most abundant species was Allograpta exotica (60.43%), followed by Toxomerus dispar (17.78%) and Toxomerus watsoni (7.26%) (Diptera: Syrphidae). An important inference was that all... |

ABSTRACT: This study investigated the natural parasitism of Mythimna sequax Franclemont, 1951, in wheat during the crop season of 2008. In total, 237 larvae were captured, of which 10.12% were parasitized. The Tachinidae species Winthemia trinitatis (Thompson, 1963), Winthemia tricolor (Wulp, 1890), Lespesia aletiae (Riley, 1879), and Lespesia archippivora Beneway, 1963 are reported for the first time parasitizing the wheat armyworm in Brazil. In addition, two other genus of parasitoids were identified, one Tachinidae Peleteria Robineau-Desvoidy, 1830 and one Ichneumonidae Ophion (Fabricius, 1798). This study reported for the first time four Tachinidae species parasitizing W. sequax, and further studies are needed to promote the conservation of these... |
