Aleurocanthus woglumi Ashby, popularly known as the citrus blackfly is considered A2 quarantine pest in Brazil and causes damage in many fruit crops, especially citrus (orange, lemon and tangerine). Few researches related to biological aspects are carried out in Brazilian environmental conditions. The present research aimed to determine the oviposition preference and duration of the life cycle of A. woglumi on different hosts. The research was carried out in a greenhouse during the period of March 2009 to March 2010. Tests of preference were done with no chance of choice in six hosts, in periods of 48 and 72 hours, beyond the comparative biology in mango and orange trees. A. woglumi showed preference for laying eggs on citrus species (lemon, orange and mandarin), maintaining a pattern of non-preference in cashew and guava trees. The orange and mango hosts did not interfere in the life cycle of the pest.
