Abstract

Resumo. Aetalion reticulatum (L.) (Hemiptera: Aetalionidae), uma cigarrinha altamente polífaga e reconhecidamente praga de várias culturas agrícolas e florestais, é relatada pela primeira vez infestando plantas de noni, Morinda citrifolia L. (Gentianales: Rubiaceae), em Brasília, Distrito Federal, Brasil. Esse novo registro aumenta a lista de hospedeiras do inseto, reforçando a necessidade de estudos mais aprofundados sobre essa cigarrinha e o seu controle.First report of Aetalion reticulatum (L.) (Hemiptera: Aetalionidae) infesting plants of noni [Morinda citrifolia L. (Rubiaceae)]Abstract. Aetalion reticulatum (L.) (Hemiptera: Aetalionidae), a highly polyphagous leafhooper and known to be pest of various agricultural and forestry crops, is reported for the first-time infesting noni plants, Morinda citrifolia L. (Gentianales: Rubiaceae), in Brasília, Federal District, Brazil. This new record increases the host’s list of this insect, reinforcing the necessity for more in-depth studies of this leafhooper and its control.

Sowing time and substrate in the production of ipê-mirim seedlings

“…According to the same authors, due to the exuberance of its yellowish flowers throughout the year, this species is one of the best ornamental elements for gardens and squares in Brazil, in all regions of the country, except where very severe frosts occur, as the species does not tolerate low temperatures. This plant is widely used as an ornamental tree in gardens, parks and in the urban environment (Castro and Montalvão, 2019). This species has been widely used in landscaping and even more in urban afforestation due to its size, which allows its use under aerial wiring.…”

First report of Aethalion reticulatum (Linnaeus, 1767) (Hemiptera: Aethalionidae) infesting plants of Coffea arabica (Linnaeus, 1753) (Rubiaceae)

“…Also, this species has a gregarious behavior, i.e., and lives in colonies formed by young apterous insects and winged adults. This species has been identified in different hosts such as Dipteryx alata (Souza;Boscardin, 2020), Morinda citrifolia (Castro;Montalvão, 2019), Triplaris americana (Pires et al, 2015), Erythrina speciosa (Zanuncio et al, 2015), and Eucalyptus cloeziana (Menezes et al, 2012). The adults measure approximately 10 mm in length, have a rust-brown color and the venation of their wings are greenish with protruding ribs (Gallo et al, 2002;Creão Duarte;Lunz, 2015).…”

Baru (Dipteryx alata Vogel, Fabaceae) as new host of the treehopper Aetalion reticulatum (Linnaeus, 1767) (Hemiptera: Aetalionidae)

“…The treehopper A. reticulatum has been described as attacking several plant species, especially exotic cultivated species, such as fruit and ornamental trees (Castro & Montalvão 2019a) and is distributed throughout most of the Brazilian territory. It has recently been described as attacking the exotic plants: teak (Tectona grandis Linnaeus F.) (Tavares et al 2018); Yellow trumpetbush (Tecoma stans (L.) Juss.…”

“…It has recently been described as attacking the exotic plants: teak (Tectona grandis Linnaeus F.) (Tavares et al 2018); Yellow trumpetbush (Tecoma stans (L.) Juss. Ex Kunth) (Castro & Montalvão 2019b); and noni (Morinda citrifolia Linnaeus) (Castro & Montalvão 2019a). In native Brazilian species, the insect has already been reported infesting açai palm (Euterpe oleraceae Martius) (Santos et al 2015) and mulungu-dolitoral (Erythrina speciosa Andrews) (Zanuncio et al 2015), which are Scientific Note species that occur in the Amazon and Atlantic Forest, respectively.…”
