    Bactericera cockerelli, better known as the potato psyllid responsible for the transmission of the phytoplasma that causes the purple top disease, this pest has a great capacity of adaptability which generates many problems in the agricultural sector, the temperature is a pillar for the propagation of this species. The objective of this research is to identify the biological cycle of Bactericera cockerelli, in potato at room temperature through a descriptive methodology that is observing the total development of its cycle compiling the information in life tables and for these two localities were chosen, Quito and Latacunga. To do all this we collected the insects in crops specifically potato, for their feeding we used potatoes that were then planted in pots which were introduced into the fish tanks and closed with tulle fabric to prevent the escape of insects. For data collection we used a digital microscope that helped us to see each stage of the cycle and a digital thermometer for the temperature. The results obtained were from Quito with a temperature range of 16 to 20°C, a total cycle of 26 days, egg stage duration of 1 to 3 days, nymph I 2 days and from nymph II to nymph V 1 to 3 days, adult I and II with a duration of 1 day, adult III 1 to 9 days and with an oviposition of 293 eggs, while in Latacunga with a temperature range of 9 to 14°C a total cycle of 37 days, its egg stage from 1 to 5 days, nymph I 1 to 7 days, nymph II 1 to 6 days, nymph III 1 to 5 days, nymph IV 1 to 5 days, nymph V 1 to 6 days, adult I 1 to 2 days, adult II 1 to 2 days, adult III 1 to 12 days and with an oviposition of 100 eggs. Biological development took 11 days longer in Latacunga, showing that temperature directly influences the biological cycle.
