In Peru, Passiflora ligularis (Juss, 1805) (granadilla) is one of the passionflowers with the highest demand in the market. Diptera of the genus Dasiops (Lonchaeidae) are detrimental to the cultivation of passionflowers because the larvae feed on the internal structures of flower buds, flowers and fruits, causing between 50 and 60% losses in the production of said crops. This research aimed to determine the incidence of Dasiops sp. in flower buds of a granadilla crop and the climatological factors (temperature, precipitation and relative humidity) of the San Pedro de Grapanazú Farm (Huancabamba - Oxapampa, Pasco, Perú), during the dry season, between the months of September and October 2020. The experimental and exploratory protocol consisted of three fortnightly collections of 50 flower buds, which were dissected to determine the incidence of Dasiops sp.; in addition, 120 flower buds ...
