“…The area drawn by the different curves was calculated to quantify the cultivar acceptability. In fact, faster development and/or longer survival constitute a reliable indication of host acceptability by the insect (Huang et al, 2020; Munyaneza & Upton, 2005; Orozco‐Restrepo et al, 2017; Zhang et al, 2018). The area for the Barbera‐reared leafhoppers was quite larger than those for the other two cultivars, especially when Moscato was considered (Table 5).…”

“…Indeed, delayed development is, in general, an index of negatively impacted fitness (Huang et al, 2020; Munyaneza & Upton, 2005), and, for example, Lobesia botrana reared on non‐preferred grapevine varieties shows delayed development (Moreau et al, 2006). Nevertheless, there are exceptions, where non‐preferred varieties induce faster development, as in the case of the spittlebug Mahanarva fimbriolata on sugarcane (Orozco‐Restrepo et al, 2017). The high nymph mortality recorded on Moscato confirmed the poor performance of the leafhopper on this genotype.…”

“…different plant varieties, temperatures and insecticides applications) (Akca et al, 2015; Akkopru et al, 2015; Xu et al, 2016; Zhang et al, 2018). Shorter survival and longer development are direct indicators of impaired fitness (Huang et al, 2020; Jandricic et al, 2010; Krechemer & Foerster, 2017; Munyaneza & Upton, 2005; Orozco‐Restrepo et al, 2017). More recently, also feeding behaviour of sap‐sucking insects has been widely and effectively applied to estimate plant acceptability, by comparing insect probing behaviour on susceptible and resistant genotypes (Baldin et al, 2018; Kordan et al, 2019; Miao et al, 2014; Ripamonti et al, 2022; Yorozuya, 2017).…”

Scaphoideus titanus (Ball) is a Nearctic leafhopper (Cicadellidae: Deltocephalinae), monophagous on Vitis spp., naturalized in European vineyards since the 20th century. Following its introduction and establishment in Europe, S. titanus became the main vector of Flavescence dorée phytoplasma (FDp) to grapevine. FDp causes heavy economic losses to viticulture in Europe. The control of the disease mainly relies on insecticide applications against the vector and on the removal of infected plants. The exploitation of plant resistance or tolerance against pathogens and pests can represent a valuable tool for a more sustainable viticulture. The first step in identifying resistance traits in grapevine varieties towards S. titanus is the evaluation of insect fitness parameters on different grapevine genotypes. Therefore, in this work, nymph mortality and developmental time, adult survival and prolificacy of S. titanus have been studied on three grapevine varieties, characterized by different susceptibility to FD. Scaphoideus titanus showed highest fitness when reared on Barbera, whereas the worst performances were recorded on Moscato, with a significant reduction in nymph and adult survivals, a slowed nymph development, and a decreased number of available eggs. On Brachetto, S. titanus showed an intermediate level of fitness parameters. Consistently with previous studies on feeding behaviour, Barbera is the most suitable host for the FD‐vector. The high suitability of Barbera for S. titanus may partly explain the high susceptibility to FD of this variety. On the contrary, the low suitability of Moscato, poorly susceptible to FD, may be due to antibiosis and antixenosis defence mechanisms that act against S. titanus.

“…Among hosts, spittlebugs show preferences for nitrogenfixing plants (Thompson, 1994). This feature, combined with their high reproductive potential and short life cycles, makes numerous Cercopidae species significant pests, particularly of forage grasses and sugar cane in Latin America (Cardona et al, 2004;Carvalho, 1990;Fagan & Kuitert, 1969;Foieri et al, 2016;Orozco-Restrepo et al, 2017;Paladini & Cryan, 2012;Peck, 2001).…”

Overview of spittlebugs of the family Cercopidae (Hemiptera: Auchenorrhyncha) from Mexico, with keys to genera and species

The Cercopidae family constitute the largest group of xylem sap-sucking insects. Several species are important pests of sugar cane and grasses. In America there are 460 species and 65 subspecies in 60 genera. In Mexico, the total number of species is unknown and there is no inventory of specimens in the collections or taxonomic keys. In the present research, we study entomological collections to trace the distribution of genera and species and constructed taxonomic keys for their identification, based on external morphology and male genitalia. The Cercopidae of the country included 3 recognized tribes, Neaenini Fennah, 1968, Ischnorhinini Schmidt, 1920 and Tomaspidini Schmidt, 1922, in addition to the recently proposed Microsarganini Hamilton, 2016. We reported 39 described species, 1 subspecies and 1 undescribed, belonging to 10 genera. The most diverse genera were Ocoaxo Fennah with 16 species and Prosapia Fennah with 8. Aeneolamia Fennah includes 3 species and 1 subspecies, Iphirhina Fennah and Neaenus Fowler 3 species each, Microsargane Fowler and Olcotomaspis Lallemand 2 species each, and Mahanarva Distant, Huaina Fennah and Zulia Fennah 1 species each. This is the first complete compilation of the Cercopidae recorded for Mexico.

“…Los insectos chupadores de la familia Cercopidae son consumidores estrictos de savia, que obtienen nutrientes del xilema de raíces y hojas de diversas plantas (Cid-Muñoz et al, 2020;Fagan y Kuitert, 1969;Peck, 1998aPeck, , b, 2003Orozco-Restrepo et al, 2017;Thompson, 1999Thompson, , 2004. La característica más distintiva de estos hemípteros, es que las ninfas mientras se alimentan, secretan una sustancia espumosa, que las protege de agentes externos y enemigos naturales, por lo que comúnmente se les nombra "salivazos" (Castro, 2017;Cryan y Svenson, 2010;Rodríguez et al, 2003;Tonelli et al, 2018).…”

Pasado y presente de los salivazos del complejo Ocoaxo de los pinos (Hemiptera: Cercopidae): distribución espacial y temporal

El complejo Ocoaxo de los pinos está integrado por 3 especies (O. assimilis, O. cardonai, O. varians) que se alimentan de la savia de las acículas de Pinus spp. provocando clorosis y su eventual caída. Los crecimientos poblacionales de estos insectos han provocado la defoliación de grandes superficies de bosque en varias localidades del país, por lo cual se les ha dado el estatus de plaga, a pesar de que aún se desconocen aspectos básicos de su biología y distribución. En el presente trabajo se analizaron los registros de especímenes depositados en colecciones entomológicas y bases de datos en línea, que permitieron definir el espacio geográfico donde estas especies están presentes en interacción con los ecosistemas de México, además de proporcionar el espectro alimenticio de su estado adulto, identificar los factores ambientales que potencialmente están asociados a su presencia, así como conocer el periodo en el que se encuentran a lo largo del año. Los análisis de estos datos también permitieron generar hipótesis espaciales de su distribución, estimar los límites de las áreas donde se han reportado y reconocer áreas potenciales para su monitoreo.
