Diversity and distribution of jumping plant-lice (Hemiptera: Psylloidea) along edges of Amazon–Cerrado transitional forests in Sorriso, Mato Grosso, Brazil

Abstract

Abstract.Little is known about the jumping plant-lice of Brazil from where seven families, 45 genera and 76 species have been previously reported, but estimates suggest that there may be as many as 1,000 species. This study reports 34 species of Psylloidea which were collected along the edges of Amazon-Cerrado natural transitional forests in the municipality of Sorriso, state of Mato Grosso, from August 2013 to July 2014. Of the species reported in this study only nine represent described taxa, two of which are reported for the first time from Mato Grosso.

First record of Glycaspis brimblecombei (Moore, 1964) and Blastopsylla occidentalis (Taylor, 1985) (Hemiptera, Aphalaridae) in eucalyptus plantations in State of Pará, Brazil

“…Later the species was recorded in regions of the country, that today sums a total of 13 states, including the insect's first occurrence in Pará, as recorded in this study (Fig. 1) (Burckhardt & Queiroz 2012, Silva et al 2013, Mazzardo et al 2017. Adults of G. brimblecombei are 2.5-3.1 mm in length, present projections from the head back side, and females are bigger than males (Paine et al 2006).…”

Detection and estimation of Mastigimas anjosi (Hemiptera: Calophyidae) populations on Cedrela fissilis trees

“…The numbers of natural enemies, negatively correlated with that of M. anjosi nymphs, indicate their greater preference to feed on nymphs than on adults of this pest, because they are smaller, apterous and low mobile [4,16]. The presence of A. opsimus, C. sanguinea and H. convergens preying upon M. anjosi on C. fissilis leaves in Sorocaba shows the importance of these natural enemies as reported for those royalsocietypublishing.org/journal/rsos R. Soc.…”

“…The traps were sent to the Entomology Laboratory of UFSCar in Sorocaba and maintained at 0.0°C until the identification and counting of M. anjosi males and females and the natural enemies of this pest, on the two sides of the traps, under a binocular stereomicroscope M125 C Leica ® (Wetzlar, Germany), with lenses with 10× magnification. Mastigimas anjosi was identified based on the analysis of its body external morphology [13,16]. The predators were identified according to analysis of their external body morphology and comparison with keys and taxonomic descriptions for the assassin bug, Atopozelus opsimus Elkins, 1954 (Hemiptera: Reduviidae) [29], the spotless ladybird beetle, Cycloneda sanguinea L., 1763 [30] and the convergent lady beetle, Hippodamia convergens Guérin-Méneville, 1842 (Coleoptera: Coccinellidae) [31].…”

“…Mastigimas anjosi is native to Brazil, and the body length of its males and females is 4.8-5.5 mm and 4.2-5.0 mm, respectively, with antennas almost as long as the body and brown. The body colour of M. anjosi is light greenish yellow with dark dots and stripes, and its membranous wings with transparent or pigmented pterostigma and veins are used in the identification of this insect [14,16,17].…”

Caracterização da movimentação de psilídeos (Hemiptera: Psylloidea) no contexto da disseminação primária do Huanglongbing dos citros

“…Dentro dos atributos descritos para a separação de Psylloidea, foram reportados dois processos autapomórficos dos escleritos basalares, ausência do processo notal mediano da asa, primeiro esclerito axilar em forma de vara, platô umeral fusionado com a base da nervura mediana subcostal, terceiro esclerito axilar pouco esclerotizado com dois braços, platô proximal médio vertical e platô distal médio dividido em dois platôs.Segundo Ouvrard, (2018) Psylloidea tem 3.528 espécies descritas, 10 táxones intraespecíficos e 52 espécies extintas. Embora, segundoMazzardo et al (2017) não têm sido descritas nem a metade de espécies que se acredita que existem. O número de espécies de psilídeos reportados em alguns continentes e países foi relacionado com a área por Burckhardt e Queiroz (2012), os quais acreditam que pelo tamanho da área do Brasil, é provável que a fração dos psilídeos relatada até agora respresenta uma pequena fração da diversidade estimada, podendo ser de mais de 1000 espécies(Burckhardt & Queiroz, 2012).Segundo os registros de Psylloidea no Brasil, existem 89 espécies de psilídeos no país(Burckhardt & Queiroz, 2012;Malenovský et al, 2015;Machado et al 2017;Serbina & Burckhardt, 2017).…”
