ABSTRACT

Yellow passionfruit (Passiflora edulis f. flavicarpa O. Deg.) is a tropical fruit crop that is meeting increasing demand both in local and international markets in South America. The lance fly, Dasiops inedulis (Diptera: Lonchaeidae), affects P. edulis floral buds and flowers, and is thought to cause important yield losses in this crop. In Colombia, D. inedulis are commonly controlled through calendar based applications of chemically synthesized insecticides, and no scientific criteria exist to guide pest management. In the present study, we simulated D. inedulis injury to passionfruit plants, over the course of three production cycles. We assessed the effect of seven different categories of flower bud removal (from 0\% to 79.9\%) on passionfruit yield and fruit quality parameters. Removal rates above 20\% caused a significant reduction in the number of flowers, while yield levels were lowest at 50\–79.9\% bud removal. With increasing rates of flower bud removal, we observed higher initial production of buds and lower levels of natural abortion of floral and fruiting structures. For the three consecutive harvests, maximum yield levels were 7.57 65.51 kg (mean6SD; with 0\–9.9\% damage), and minimum yield was 2.37 62.15 kg (60\–69.9\% damage) per plant. For fruit quality parameters, D. inedulis injury did not affect fruit pulp weight or the content of soluble solids (Brix). Our work provides insights into the impact of D. inedulis on yellow passionfruit production, and constitutes a basis for future integrated pest management programs for this pest.

Fixed effects of period (F = 26.61, df = 3, 11.6;P < 0.0001) and attractant trap type x period interaction (F = 4.30, df = 3, 11.6;P = 0.0293) were significant. Significantly moreL. striatifrons were captured in traps containing propylene glycol antifreeze than in ethylene glycol antifreeze (21-d trapping period). Additionally, ethylene glycol antifreeze (28-d trapping period) and propylene glycol antifreeze (21- and 28-d trapping period) captured significantly moreL. striatifrons, than did mineral oil and control traps. These findings suggest that ethylene glycol antifreeze and propylene glycol antifreeze are more attractive toL.striatifrons than to mineral oil and decaying insects. Because L. striatifrons is known to breed in rotting plants (Hardy and Delfinado 1980), it seems that decaying insects are not attractive, because trap captures were significantly lower for both mineral oil and control traps.}, author = {Grant K.
