Diversidade, distribuição e plantas hospedeiras de cochonilhas escama (Hemiptera: Diaspididae) no Espírito Santo, Brasil

Abstract

Abstract: Armored scale insects (Hemiptera: Diaspididae), are phytophagous species that occur in major biogeographic regions of the world. Because of the importance of diaspidids as pests, there is widespread interest in countries that export and import unprocessed agricultural products in increased knowledge of this group which includes invasive and quarantine pests of great economic concern. The diversity, geographic distribution, and host of diaspidids were studied from November 2002 to December 2018 in 34 municipalities in the state of Espírito Santo, Brazil. Forty species of Diaspididae from 27 genera were collected and identified. The species Acutaspis perseae (Comstock), A. umbonifera (Newstead), Aonidiella aurantii (Maskell), Comstockaspis perniciosa (Comstock), Lepidosaphes beckii (Newman), Lepidosaphes gloverii (Packard), Morganella longispina (Morgan), Mycetaspis apicata (Newstead), and Thysanofiorinia nephelii (Maskel) were found for the first time in Espírito Santo. The plant families Myrtaceae, Moraceae, Arecaceae, Asparagaceae, and Rutaceae had the greatest number of host plant species of armored scale. Fifty-seven new host associations were observed for 25 species of diaspidids and 11 diaspidid species were recorded for the first time from nine families of plants. Selenaspidus articulatus (Morgan) was the most polyphagous species observed with 17 host plant species from 12 families, followed by Pseudaonidia trilobitiformis (Green), and Parlatoria proteus (Curtis). With these new records, 41 species and 28 genera of Diaspididae have been recorded in Espírito Santo.
