Detecção de Aethalion reticulatum (L., 1767) (Hemiptera: Aethalionidae) em alfavaca-cravo (Ocimum gratissimum L.) e observações sobre sua ocorrência

Abstract

RESUMO:O objetivo deste trabalho foi relatar a ocorrência da cigarrinha Aethalionidae em alfavacacravo (Ocimum gratissimum L.) no município de Bandeirantes-PR. Plantas com cerca de dois anos, na fase reprodutiva, com inflorescências, flores, frutos e sementes, serviram como fonte para a coleta de ninfas e adultos das cigarrinhas. Registrou-se em alfavaca-cravo a espécie Aethalion reticulatum e a interação com as formigas Camponotus rufipes e C. crassus.Palavras-chave: Aethalionidae, cigarrinha das fruteiras, alfavaca ABSTRACT: Detection of Aethalion reticulatum (L., 1767) (Hemiptera: Aethalionidae) in clove basil (Ocimum gratissimum L.) and observations of its occurrence. The aim of this work was to report the occurrence of the leafhopper Aethalionidae in clove basil (Ocimum gratissimum) in Bandeirantes Municipality, Paraná State, Brazil. Plants around two years old, in the reproductive phase, presenting inflorescences, flowers, fruits and seeds, were used as source for collection of leafhopper nymphs and adults. In clove basil, the species Aethalion reticulatum was recorded, in addition to its interaction with the ants Camponotus rufipes and C. crassus.

Isolated and Community Contexts Produce Distinct Responses by Host Plants to the Presence of Ant-Aphid Interaction: Plant Productivity and Seed Viability

“…Ants may affect plants directly, such as herbivory from fungus-growing ants [ 13 ] or protection against herbivores by plant-tending ants [ 22 , 23 ], or indirectly, such as protection of mutualistic hemipterans [ 20 , 24 , 25 ] or decreasing visits of pollinators [ 26 ].…”

“…This pest sucks the sap from the stalk of the fruits leading to atrophy and losses before harvest, as reported for mango, Mangifera indica L. (Sapindales: Anarcadiaceae), in Mexico (Waite 2002). The egg clutches of A. reticulatum are often confused with the bark of fruit plants where the gray-brown substance covering the eggs serves to camouflage them and protect against natural enemies (Rando & Lima 2010). The females of this insect lay up to 100 eggs on the branches or stems of the fruits of host plants (Rando & Lima 2010).…”

“…Permanecem nesta fase durante 45 dias, completando seu ciclo em torno de 110 dias, com três gerações ao ano (SaNtaNa et al 2005 BarôNiO et al 2012). É um inseto polífago, que se alimente de seiva das folhas e ramos de plantas medicinais, nativas, leguminosas, ornamentais, invasoras, florestais e, principalmente, frutíferas (Silva et al 1968;cOSta 1986;gallO et al 2002;SaNtaNa et al 2005;carvalHO 2007;azevedO et al 2008;OtO et al 2009;raNdO & liMa 2010;MeNezeS et al 2012;caMilO et al 2013), mas que ainda não havia sido relatado associado ao açaizeiro.…”
