Hymenopterous parasitoids of Dasiops (Díptera: Lonchaeidae) infesting cultivated Passiflora spp. (Passifloraceae) in Cundinamarca and Boyaca, Colombia

Abstract

Dasiops spp. are the most important pest in cultivated Passiflora plants. Larvae of these fruit flies are herbivores, feeding on flower buds and fruit of yellow passionfruit, sweet granadilla, banana passionfruit and purple passionfruit crops located in Cundinamarca and Boyaca, Colombia. Geographic distribution, natural abundance and percentage of parasitoidism for every Dasiops species by each plant species were determined. Aganaspis pelleranoi (Hymenoptera: Figitidae) was found to be a parasitoid of D. inedulis (14.19-50.00%), infesting flower buds of yellow passionfruit and fruit of sweet granadilla (7.41%). Microcrasis sp. (Hymenoptera: Braconidae) was found to be parasitizing both D.gracilis (0.83-3.13%) and D. inedulis (0.83%) in purple and yellow passionfruit. Trichopria sp. and Pentapria sp. (Hymenoptera: Diapriidae) were found to be parasitizing D. inedulis (40.00% and 4.17-20.00%, respectively) and D. gracilis (1.69-22.22% and 1.67-29.17%, respectively) in purple passion fruit. Dasiops caustonae was found to be infesting banana passionfruit only in Boyaca, naturally parasitized by Pentapria sp. (11.11-33.33%). Because Pentapria sp. had a wide geographical distribution as an idiobiont of Dasiops spp. pupae, in all of the assessed cultivated Passiflora species, despite a high selection pressure by chemical control distributed at regular calendar intervals, it would be a crucial strategy in pest management control. Collecting fallen flower buds and fruit infested by Dasiops spp. is important to truncate the life cycle of fruit flies and allow emergence of parasitoids. This simple cultural strategy could have important implications in reducing production costs, increased crop yields and environmental care.

Flower bud fly infestation and its relationship with the morphological and phenological aspects of sour passion fruit (Passiflora edulis) in southern Santa Catarina state

“…Parasitoids of the genus Aganaspis (Figitidae) had already been reported in Colombia parasitizing D. inedulis pupae by Quintero et al (2012). The species A. pelleranoi was recorded for the first time for fly species of the genus Dasiops by Santamaría et al (2016) and was also recorded in the present study, which is the first report of this association in the country. Furthermore, this parasitoid is also known to parasitize larvae-pupae of Neosilba sp., in addition to several species of the genus Anastrepha (GUIMARÃES et al, 2003).…”

“…en botones florales de pasifloráceas; y Santamaría et al (2014) quienes obtuvieron únicamente la eclosión de moscas del género Dasiops a partir de botones florales de cuatro especies de pasifloráceas, entre ellas la granadilla. Al respecto Santamaría at al. (2016) también obtuvieron la eclosión de individuos adultos de Dasiops sp.…”

Plant extracts in reducing the infestations of Dasiops spp in the cultivation of passion fruit

“…Vera y Enrique (2016) indican que la mosca al permanecer inactiva durante la noche y en períodos de lluvias fuertes, utiliza los días cálidos para su con mayor desplazamiento. Las larvas salen de la flor y pupan en el suelo; el ciclo de vida varía alrededor de 22,8 días (Santamaría et al, 2016), cada órgano puede albergar numerosas larvas en botones florales, lo cual puede incidir en la abundancia relativa de la población. En este contexto Santamaría, (2014) menciona que el reconocimiento de síntomas de infestación permite adoptar medidas con el propósito de interrumpir el ciclo de vida de estos insectos y hacer un uso racional del control químico.…”
