Deuterollyta majuscula (Herrich-Schaffer) causes injuries to leaves and fruits of avocado. The aim of this work was study the biology under laboratory conditions, at 25±2ºC, 70±10% of RH, and 14-hour of photophase and to describe the damage caused by this pest. The biological cycle (egg-adult) was 39.6 days and the total viability was 55%. Five instars were observed. The pupae weight was 0.0966 mg for females and 0.0901 mg for males. The females laid an average of 201 eggs in approximately 7.6 days. The mean longevity of males and females was 15.3 and 13.9 days, respectively, and sex ratio of 0.56. The fertility life table showed a 64-fold increase capacity in each generation, with one generation lasting an average of 46 days, with finite rate of increase (lambdal) of 1.095. These results can provide background information to the establishment of strategies to manage this new avocado pest.
