Monitoreo del Psílido bactericera cockerelli en el Cultivo de Papa (solanum tuberosum l.) en el Campus CEASA de la Universidad Técnica de Cotopaxi – Salache, 2020.

In this investigation determined as Monitoring of the psyllid Bactericera cockerelli in the crop potato (Solanum tuberosum L.) at the CEASA campus of the Technical University of Cotopaxi - Salache, 2020. The objectives of this study were: To characterize the abundance and record the population of B. cockerelli at the CEASA campus of the Technical University of Cotopaxi and to establish the phenological cycle in the development of B. cockerelli in the field, to carry out these objectives a descriptive statistical analysis was carried out with the application of averages, to the monitoring of ovipositions, nymphs and adults where for the oviposition sampling twenty plants were selected at random, where the presence of B. cockerelli was monitored and recorded diagonally in an X shape in a time of five minutes, for the sampling of nymphs In each plant, 4 leaflets were selected, counted from the apical part to the lower part, and yellow horiver traps were located for the adults. For the raising of B. cockerelli, it was carried out under a temperature with its relative humidity where the phenological states in the development of B. cockerelli were observed. The results of this study revealed that an average of 8 eggs / plant emerged in the identification of ovipositions; while in the nymph count I averaged 1 nymphs / plant. In the phenological cycle of B. cockerelli it was clearly observed when the temperature increases (19.7 ° C) and the relative humidity decreases (66%), the biological cycle is shorter, at low temperatures the psyllid has a delay in its life cycle of 30 to 35 days.
