Description
Summary:	The passion fruit crop in Colombia is affected by the presence of Dasiops inedulis S., a pest that affects yield by feeding on flower buds, leading to the use of pesticides to control its population, generating toxic residuals in fruit and affecting the health of the producers. A comparison of the management of the black fly of the button, between the one made by 3 farmers of the town of La Plata - Huila (T2), with the integrated management proposed by Corpoica (T1); Analyzing the technical, economic and environmental variables of both treatments. The T1 consisted of biweekly sampling to measure the incidence, recollection of affected flower buds, and chemical management when exceeding the 30% action threshold by rotating the following products: Spinosad, Malathion or Thiacloprid with deltamethrin. For the technical variable, T1 maintained a lower Dasiops population, with 17.4% while T2 had 24.8%; For the economic part, the weekly costs, production and the profitability of the crop, were compared, showing that the costs of T1 are slightly higher and the best profitability was obtained in farm 2 with 789,276cop / ha, more in the T2 than in the T1; For the environmental part an analysis of residuality in fruits was performed, showing that both treatments exceed the MRL allowed by the European Union, and the smallest number of applications in the 3 farms was in the T1 treatment, and supported by the environmental impact quotient of pesticides (EIQ), that shows us the impact caused in the producers, consumers and environment, was lower in the proposed management. It is possible to say that the integrated management proposal of Corpoica, allows to maintain a smaller population of fly D. inedulis without leaving high residuality in fruits and diminishing the chemical applications, considerably reducing the environmental impact of the management of this pest, and increasing the profit of the crop.
