This study reported for the first time the occurrence of the pink hibiscus mealybug Maconelli-coccus hirsutus (Green, 1908) (Hemiptera: Pseudococcidae) in Maceió, Alagoas, Brazil attacking the following fruit species: soursop (Annona muricata L.) (Annonaceae), guava (Psidium guajava L.) (Myrtaceae), mango (Mangifera indica L.) (Anacardiaceae), carambola (Averrhoa carambola L.) (Oxalidaceae), acerola (Malpighia glaba L.) (Malpighiaceae), cajazeiro (Spondias lutea L.) (Anacardiaceae) and cupuaçuzeiro (Theobroma gran-diflorum) (Willd. ex Spreng.) Schum.) (Malvaceae). The percentages of injured plants were recorded for each plant species in the field. Damaged plants showed short internodes, wrinkled leaves, fruit deformation, and sooty mold developed on the honeydew excreted by the mealybugs. Infested plant structures were taken to the Laboratory of Entomology of the Center for Agricultural Sciences, of the Federal University of Alagoas, where the mealybug species was identified through morphological characteristics. The following injury percentages were recorded on the plants: soursop (100%), guava (10%), mango (10%), carambola (100%), acerola (100%), cajá (50%) and cupuaçu (100%). The mealybug collected in Maceió, AL; Brazil was identified as Maconelli-coccus hirsutus (Green, 1908) (Hemiptera: Pseudococcidae). It was the first record of this species in the state of Alagoas and infestation by pink hibiscus mealybug on the host plants mango, acerola and cajazeiro in Brazil.
