However, male mealybugs do exhibit a radical change during their life cycle, changing from wingless, ovoid nymphs to wasp-like flying adults. Generally, within two to 10 days, new mea- lybugs (crawlers) emerge and start to go out of the ovisac [4]. It has been introduced to the rest of the world, including Europe, the Americas, and Oceania, as an agricultural pest. The use of insecticides against this species is … ficus (Daane et al. They develop through several stages (instars) over several weeks before reaching sexual maturity. When damage is serious, leaves may bleach or burn at the tips and leaf drop may occur.
