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.
Resumo: As cochonilhas escama (Hemiptera: Diaspididae), são espécies fitófagas que ocorrem nas principais regiões biogeográficas do mundo. Devido à importância dos diaspidídeos como pragas, existe um amplo interesse nos países que exportam e importam produtos agrícolas não processados no aumento do conhecimento desse grupo, o que inclui pragas invasoras e quarentenárias de grande importância econômica. A diversidade, distribuição geográfica e hospedeiros de diaspidídeos foram estudadas de novembro de 2002 a dezembro de 2018 em 34 municípios do estado do Espírito Santo, Brasil. Quarenta espécies de Diaspididae de 27 gêneros foram coletadas e identificadas. As espécies Acutaspis perseae (Comstock), A. umbonifera (Newstead), Aonidiella aurantii (Maskell), Comstockaspis perniciosa (Comstock), Lepidosaphes beckii (Newman), Lepidosaphes gloverii (Packard), Morganella longispina (Morgan), Mycetaspis apicata (Newstead) e Thysanofiorinia nephelii (Maskel) foram encontradas pela primeira vez no Espírito Santo. Cinquenta e sete novas associações de hospedeiros foram observadas, em um total de 25 espécies de diaspidídeos; estes incluem 13 novos registros de famílias em um total de 11 espécies de diaspidídeos e nove famílias de plantas. Myrtaceae, Moraceae e Arecaceae foram as famílias botânicas com o maior número de espécies de diaspidídeos observadas. Selenaspidus articulatus (Morgan) foi a espécie mais polífaga, com 17 espécies de plantas hospedeiras de 12 famílias observadas, seguida por Pseudaonidia trilobitiformis (Green) e Parlatoria proteus (Curtis). Com esses novos registros, 41 espécies e 28 gêneros de Diaspididae foram registrados no Espírito Santo.
ABSTRACT
ABSTRACT As a result of recent field work in southern Iran from 2012 to 2016, twenty species of armoured scale insects were collected, representing two subfamilies (Aspidiotinae and Diaspidinae) and 4 tribes including Aspidiotini (8 species in 5 genera), Diaspidini (4 species in 2 genera), Leucaspidini (5 species in 4 genera) and Parlatoriini (3 species in 1 genus). The species Diaspidiotus gigas (Thiem and Gerneck), is illustrated and redescribed from Iran for the first time. In addition, four species are reported and redescribed from south of Iran for the first time: Aspidiotus nerii Bouché, Diaspidiotus armenicus Borchsenius, Leucaspis pusilla Löw, Melanaspis louristana Balachowsky and Kaussari.
ABSTRACT
ABSTRACT Coffee is one of the most important Brazilian agricultural commodities exported, and Minas Gerais and Espírito Santo States are the main coffee producers. Scale insects are important coffee pests, and 73 species of Cerococcidae (3), Coccidae (18), Diaspididae (6), Eriococcidae (1), Ortheziidae (3), Pseudococcidae (21), Putoidae (2) and Rhizoecidae (19) have been associated with roots, branches, leaves, flowers and fruits of Arabica coffee in the Neotropics. Eight species were found associated with Arabica coffee in Minas Gerais and Espírito Santo States in this study, and Coccidae was the most frequent family. Coccus alpinus, Cc. celatus, Cc. lizeri, Cc. viridis, and Saissetia coffeae (Coccidae) were found in both states; Alecanochiton marquesi, Pseudaonidia trilobitiformis (Diaspididae), and Dysmicoccus texensis (Pseudococcidae) were only found in Minas Gerais. Alecanochiton marquesi and P. trilobitiformis are first reported in Minas Gerais, and Cc. alpinus in Espírito Santo, on Arabica coffee. All scale insect species were associated with coffee leaves and branches, except D. texensis, associated with coffee roots. Fourty seven scale insect species have been found occurring in Brazilian Arabica coffee, and in Espírito Santo (28) and Minas Gerais (23). Widespread and geographical distribution of each species found are discussed.
