Infestation, survey and identification of fruitflies and their natural enemies in coffee

Abstract

The study presented here about infestation, recognition, fluctuation, and identification of fruits flies and its natural enemies in coffee berries was developed in Tangua and Yacuan­quer (Nariño Colombia), at 1,680 and 1,750 masl, with a mean relative humidity of 77,79%, and a mean temperature of 23°C. The speci­mens were identified at the ICA 's Sanidad Vegetal Laboratory and at the University of Nariño Insect Collection in Pasto. The fruits file species reported attacking coffee berry were: Ceratitis capitata, Anastrepha frater­culus, and Neosilba glaberrima. Three species of fruit fly parasites were identified: Doryc­tobracon crawfordi, Opius anastrephae, and Microcrasis n.sp. The total parasitism percentage was 3,48%. The infestation by the fruit flies was 17,69%, the number of larvae/ kg of dry berries was 159,62 and the average number of larvae/berry was 1,4. The highest percentage of infestation occurred at the end of the harvest time and during the dry season.
