This study was made to describe the developmental stages of the Harrisia cactus mealybug (HCM), the effects of temperature in its life cycle, the ability to detect immature and males (on their nuptial flights) by the use of sticky traps, and to ob- tain a mass production for insect pest in laboratory conditions using alternate hosts. The results point out new discoveries about the morphology of HCM, like the presence of trilocular pores, and absence of multilocular pores in the first stage of life. As expected, it was observed that stages develop more rapidly as the temperature increases. We found that the number of HCM males is higher in medium yellow traps in comparison to all other traps used. The development and feeding habits were observed in both Portulaca sp. and Alternanthera sp in where on average and stable temperature (° F) the life cycle can be completed in 30 days in Portulaca, and 27 days in Alternanthera.
