Citrus Mealybug Planococcus citri (Risso) (Insecta: Hemiptera: Pseudococcidae) 3 Population Dynamics Mealybugs are most common during the spring and early summer. P. ficus is closely related to P. citri. Generally, within two to 10 days, new mea- lybugs (crawlers) emerge and start to go out of the ovisac [4]. Use Citripar for biological control of citrus mealybugs (Planococcus citri) and vine mealybugs (Planococcus ficus). The “life cycle” of parental imprinting. are helpful in predicting Pl. Pernicious insects and mites fauna in Croatian orhards. Eggs hatch in 6 to 10 days, and they mature in 6 to 8 weeks ( Baker, 1978; Nakahara and Williams, 1980; Pirone, 1978 ).

The elaboration of the parent-of-origin-specific epigenetic information during animal development is achieved in three steps, namely, establishment, maintenance, and erasure. Moderate to heavily-infested trees produce fewer and less vigorous fruit buds. NYMPHS. Life Cycle: In warm climates, live longtailed mealybug young are believe to be produced without fir producing eggs. The duration of the life cycle of the coccinellid Cryptolaemus montrouzieri fed on the coccid Chloropulvinaria psidii and the pseudococcid Planococcus citri was determined in the laboratory at 18-28°C and 62-94% RH. Citrus mealybug populations are generally composed of equal numbers of males and females. The adults lived for approximately 2 days and the females produced on average 34, 25, and 19 eggs at temperatures of 22, 25, and 28 °C, respectively.
