Primeiro registro de Platycorypha nigrivirga Burckhardt (Hemiptera: Psylloidea), em Tipuana tipu (Benth.), no Brasil

Abstract

-The occurrence of Platycorypha nigrivirga Burckhardt (Hemiptera: Psyllidae, Acizzinae), is reported for the fi rst time, in Brazil. The psyllid was observed causing injuries on leaves and shoots of Tipuana tipu (Benth.), in urban areas of Paraná State. P. nigrivirga are tiny sap-sucking insects that feed on phloem and cause curling, stains and fall of leaves. The excrements of these insects accumulate on the leaves propitiating fungus growth on the leaves, or they fall in great amount on the cars dirtying them as if they were sparkling of white and sticky ink.

First record of Heteropsylla tenuata from Argentina (Hemiptera: Psyllidae), and additional notes on other psyllid species

“…Immatures and adults produce sugar drops or honeydew in large amounts, hindering photosynthesis and respiration of the plants. At high population levels, the species can become a nuisance by soiling sidewalks, streets and cars with honeydew (Santana et al, 2006;Rung et al, 2009;SINAVIMO, 2021).…”

“…Some specimens, or parts, such as forewings, head and terminalia were slide-mounted following Queiroz et al (2017) and labelled for taxonomic study. Specimens were identified following the keys and descriptions by Burckhardt (1987), Muddiman et al (1992), Hodkinson & Muddiman (1993), Santana et al (2006), Burckhardt (2008), Rung et al (2009) and Queiroz et al (2010). Images were taken with a Leica DFC 295 camera attached to a Leica S8APO stereoscopic microscope and to a Biotraza XSZ146AT microscope.…”

PRIMEIRO REGISTRO DE Platycorypha nigrivirga BURCKHARDT, 1987 (HEMIPTERA: PSYLLIDAE, PSYLLINAE) EM Tipuana tipu (BENTH., 1898) (FABACEAE) NO RIO GRANDE DO SUL, BRASIL

“…Esse psilídeo infesta ramos novos, pecíolos e folhas de T. tipu, único hospedeiro relatado até o momento no Brasil, assim como nos outros países onde o inseto foi detectado. Seus danos são caracterizados pelo encarquilhamento, manchas e queda de folhas (Santana et al, 2006).…”

“…Uma alternativa para o manejo deste inseto seria por meio do controle biológico. No Estado do Paraná, Santana et al (2006)…”

“…O psilídeo da tipuana, Platycorypha nigrivirga Burckhardt, 1987 (Hemiptera: Psyllidae, Psyllinae), foi observado pela primeira vez no Brasil no ano 2000, em plantas de Tipuana tipu (Benth., 1898) (Fabaceae) na cidade de Curitiba, Estado do Paraná (Santana et al, 2006). Essa espécie vegetal é bastante utilizada na arborização urbana em diversas cidades brasileiras por causa de seus aspectos paisagísticos (Lorenzi et al, 2003).…”
