Abstract

SANTAMARIA GALINDO, Maikol Yohanny; CASTRO AVILA, Ángela Patricia; EBRATT RAVELO, Everth Emilio  and  MARGARITA BROCHERO, Helena Luisa. Characterization of Damage of the Genus Dasiops Flies (Diptera: Lonchaeidae) from Cultivated Passiflora spp. (Passifloraceae) in Colombia. Rev. Fac. Nac. Agron. Medellín [online]. 2014, vol.67, n.1, pp.7151-7162. ISSN 0304-2847.  http://dx.doi.org/10.15446/rfnam.v67n1.42605.

The flies of the gender Dasiops Rondani are the most limiting plague in pasifloras crops in Colombia, thus species identification is important for decision making for monitoring and control. The symptoms and damage caused by Dasiops spp. flies in flower buds and fruits of yellow passion fruit (Passiflora edulis f. flavicarpa Sims), purple passion fruit (Passiflora edulis f. edulis Sims), sweet passion fruit (Passiflora ligularis Juss) and banana passion fruit (Passiflora tripartita var. mollissima Nielsen y Jorgensen) were characterized. In yellow passion fruit, purple passion fruit and sweet passion fruit flower buds, the infestation was evidenced in flower buds with length greater than 1 cm, the infestation was evidenced with general yellowing and wrinkling. In purple passion fruit infestation was evidenced by wrinkling of the epicarp in immature fruits. In banana passion fruit infestation was characterized by a narrowing in the basal, apical or central part of the fruit. Infestation in flower buds was between 0.0 and 9.9% whereas in fruits showed a range between 0.3 and 28.5%. However, yellow passion fruit and purple passion fruit flower buds were infested but without the described symptoms, while in yellow passion fruit and sweet passion fruit the same phenomenon was observed in fruits. This study provides tools for farmers and technicians for recognizing Dasiops spp. fly infestation in Passiflora crops as a key element in decision making for surveillance and phytosanitary control.
