Evaluación de diferentes densidades de liberación de Apanteles gelechiidivoris Marsh (Hymenoptera: Braconidae) para el control de Tuta absoluta Meyrick (Lepidoptera: Gelechiidae) en condiciones comerciales
The main plant protection agents present in the tomato crop (Lycopersicon esculentum) (Mill) is Tuta absoluta Meyrick (Lepidoptera:Gelechiidae), pest that may be present in all developmental stages of the crop, cause losses close to 100%, damage reported include reduced leaf area, drilling of flowers, stems and fruits. In order to avoid these economic losses chemical control is implemented as the main strategy to control the pest, however, this presents a number of environmental, social and economic gains in the production of the tomato crop. Therefore, through this work we propose a biological control of T. absolute, based on the density of the pest and not on the criterion of presence/absence. To do this we determined the threshold of economic damage of the pest and natural enemy parasitic capacity Apanteles gelechiidivoris (Hymenoptera: Braconidae) in commercial greenhouse conditions in the region of Boyaca, Colombia. For the level of damage, estimated quality criteria such as size, weight and number of fruits produced by the infestation of 0, 7, 15, 20, 30 and 40 larvae of the pest/plant, was established damage threshold economic with 7 larvae/plant. Regarding the parasitic capacity of A. gelechiidivoris was estimated in a ratio of 6:1 (third instar larvae of the pest:parasitoid females). With this information we can make the right decisions at the right time, implementing biological control for control of T. absolute greenhouse conditions in Boyaca, Colombia
