Diaspidídeos e parasitoides associados ao cultivo da videira no Rio Grande do Sul, Brasil

Abstract

The most frequent and abundant specie of armored scale insect was Hemiberlesia lataniae (Signoret, 1869). Melanaspis arnaldoi (Costa Lima, 1924) and Pseudaonidia marquesi (Costa Lima, 1924) were recorded for the first time in V. labrusca. All these species showed perforations in the scale cover indicating the presence of parasitism in the field.

Diversity, distribution and host plants of armored scale insects (Hemiptera: Diaspididae) in Espírito Santo, Brazil

“…The diaspidid infested plant samples collected (leaves, stems, fruits, and pieces of trunk or branches) were placed in plastic bags and transported from the field to the Laboratory of Entomology of the Instituto Capixaba de Pesquisa, Assistência Técnica e Extensão Rural (Incaper), Vitória, Espírito Santo, where parts of the plant samples with attached diaspidids were stored and preserved in glass vials with 70% alcohol. For identification of species, the samples were cleared with potassium hydroxide (10%), dehydrated in 70% and 96% alcohol and mounted on glass slides in Canada balsam (Wolff et al 2014). Identification of each species was based on morphological characteristics of the adult female, using an optical microscope and relevant identification keys (Ferris 1937, 1938, 1941, 1942, McKenzie 1937, Lepage & Gianotti 1944, Balachowsky 1954).…”

Hemiberlesia lataniae (Signoret, 1869) (Hemiptera: Diaspididae) in Piper species (Piperaceae) in state of Pará, Brazil

“…The present study reports the armored scale insects H. lataniae in the species P. cernuum and P. reticulatum for the first time in Brazil and South America. Consequently, the species currently has a recorded occurrence in Brazil in hosts belonging to 25 botanical families (Foldi 1988;Claps et al 2001;Claps & Wolff 2003;Wolff 2014;Wolff et al 2014;Almeida et al 2018;Martins et al 2022). The species P. nigrum (black pepper) is widely cultivated in the northern Brazilian states and used as a condiment.…”

Pinnaspis strachani (Cooley) (Hemiptera: Diaspididae) infesting neem trees (Azadirachta indica A. Juss., Meliaceae) in Bahia, Brazil

“…Samples of leaves, stems, and pieces of bark from the trees with the scale insect were stored in Falcon tubes, containing 70% alcohol, and later mounted on slides for viewing under an optical microscope, following the methodology adapted and described by WoLff et al (2014). The individuals obtained were identified by the co-author of this work using a description and classification key (CLaPS & WoLff 2003).…”
