In the present investigation, the biological cycle of Diaspis echinocacti (Bouché, 1883) (Hemiptera: Diaspididae) was studied, in addition to other biological parameters for the adult female, using prickly pear cactus cladodes (Opuntia ficus-indica) as host, underenvironmental conditions in the Ecology laboratory of the Museo de Entomología Klaus Raven Büller of the Universidad Nacional Agraria La Molina (UNALM); during the winter season 21.5 ± 1.5 o C and 70 ± 4% RH (June to September 2018) and autumn season 27 ± 2 o C and 80 ± 2% RH (March to June 2019). A mass rearing was carried out in order to obtain a pure batch breeding that served to start evaluations of both the biological cycle and other biological parameters considering two repetitions for each time of year. The life cycle duration for females in winter was 53.05 days and for males 51.05 days; in autumn it was 39.75 days for females and 37.25 days for males. These results reflect the influence of temperature on the biological cycle of D. echinocacti in autumn and this is the opposite in winter. In reference to the evaluation of other biological parameters for adult females, the following were recorded: oviposition capacity with an average of 120 ± 30 eggs per female; Oviposition rate of 2 - 6 eggs / female / day and its longevity of 44.75 days for the autumn season.References
