“…A atividade fotossintética é interrompida, causando lesões necróticas que se espalham longitudinalmente até o ápice das folhas. Como consequencia, a produção de massa seca, digestibilidade e qualidade da forragem é significativamente reduzida (VALÉRIO; WIENDL; NAKANO, 1988;HOLMANN;PECK, 2002).…”

ResumoAs cigarrinha-das-pastagens são consideradas as mais importantes pragas em pastagens tropicais. Os danos ocasionados por estes insetos diminuem a produção das pastagens. O objetivo deste trabalho foi estudar a flutuação populacional de Notozulia entreriana, no período de junho de 2007 a junho de 2008, e a correlação com os fatores meteorológicos/ambientais (precipitação pluviométrica, temperatura, radiação solar diária e altura da pastagem). Para tanto, amostraram-se três áreas de pastagem no município de Marechal Cândido Rondon-PR. Foram realizadas amostragens de adultos e ninfas. Também se determinaram quais as espécies de cigarrinhas-das-pastagens (Hemiptera: Cercopidae) ocorrem na região oeste do Estado do Paraná. A flutuação populacional de N. entreriana apresentou quatro picos durante o período favorável de desenvolvimento -primavera/verão. A radiação solar diária apresentou maior correlação com a dinâmica populacional. Por outro lado, precipitação pluviométrica, temperatura e altura da pastagem apresentaram pouca correlação com a dinâmica populacional. A espécie que ocorreu com maior abundância foi N. entreriana, representando 88,4% do total de insetos coletados na região oeste do Paraná. Palavras-chave: Cercopídeos, radiação solar diária, dinâmica populacional, Cynodon dactylon. Rhynchospora sp AbstractThe spittlebugs are considered the most important pests in tropical pastures. The damages caused by these insects decrease the production of pastures. The objective this work was to study the population dynamics of Notozulia entreriana, from June 2007 to June 2008, and the correlation with meteorological and environmental factors (rainfall, temperature, daily solar radiation and pasture height). Therefore, sampled were made in three areas of grassland in the municipality of Marechal Cândido Rondon-PR. Sampling of adults and nymphs was made. Also we determined which species of spittlebugs (Hemiptera: Cercopidae) occur in the western region of Paraná State. The population fluctuation of N. entreriana showed four peaks during the period of favorable development -spring / summer. The daily solar radiation had a higher correlation with the population. Rainfall, temperature and pasture height had little correlation with the population dynamics. The species that occurred with greater abundance was N. entreriana, representing 88.4% of the total insects collected in western of Paraná State.

“…Esta gramínea africana está bien adaptada a los suelos pobres, ácidos y con alto contenido de aluminio intercambiable. Se estima que cerca de 40 millones de ha se hallan sembradas en Suramérica (Pizarro et al 1996) y en Colombia existen cerca de 5,860,000 ha sembradas con B. decumbens u otras especies de Bracharia tanto en el trópico bajo húmedo como en el seco (Holmann & Peck 2002). Los pastos del género Bracharia han proporcionado ventajas económicas y agronómicas a los ganaderos de Suramérica.…”

-We studied the population fluctuation of nymphs, adults, eggs and natural enemies of the spittlebug Zulia carbonaria(Lallemand) (Homoptera: Cercopidae) associated with Brachiaria dictyoneura pastures of the Cauca River Valley, Colombia. Our objective was to describe spittlebug phenology under seasonal conditions of bimodal precipitation (March-May and September-November). Weekly, over two years, populations of spittlebugs and certain natural enemies were quantified using a sweep net (adults) and counts of nymphs in spittle masses. To obtain eggs and study their development, adult females were collected weekly and placed in petri dishes with moist filter paper to oviposit. In both survey years 3-4 generations of Z. carbonaria were documented with a mean life cycle of 66 days. Populations were most abundant in the first semester and decreased dramatically over the course of the second semester, even in the rainy months (September-November). Very few diapausing eggs were detected (0.5%). Natural enemies included the nymph predator Salpingogaster nigra Schiner (Diptera: Syrphidae), parasitic mites of adults (Acari: Erythraeidae) and fungi of various genera. Although Z. carbonaria synchronizes its life cycle with the rains of the first semester, no role of diapausing eggs was detected as is common in other spittlebug species under conditions of unimodal precipation. Possible explanations for this synchrony and for the scarcity of the insect under the rainy conditions of the second semester are discussed.KEY WORDS: Brachiaria, egg diapause, forage grass pest, Salpingogaster nigra, seasonality RESUMEN -Se estudió la fluctuación poblacional de ninfas, adultos, huevos y enemigos naturales de Zulia carbonaria (Lallemand) (Homoptera: Cercopidae) asociado con pastos de Brachiaria dictyoneura en el valle geográfico del río Cauca, Colombia. El objetivo de este trabajo fue describir la fenología de Z. carbonaria bajo las condiciones estacionales de precipitación bimodal (marzo-mayo y septiembrenoviembre). Semanalmente, durante dos años, se cuantificaron las poblaciones del salivazo y ciertos enemigos naturales mediante pases de jama (adultos) y conteos de ninfas en masas de espuma. Para obtener huevos y estudiar su desarrollo, semanalmente se recolectaron adultos hembras que se pusieron a ovipositar en cajas de petri con papel filtro húmedo en su interior. En ambos años de muestreo se documentaron 3-4 generaciones de Z. carbonaria con un ciclo de vida promedia de 66 días. Las poblaciones fueron más abundantes en el primer semestre y disminuyeron dramáticamente en el transcurso del segundo semestre, aún en los meses lluviosos (septiembre-noviembre). Se encontró muy bajo número de huevos diapáusicos (0.5%). Los enemigos naturales encontrados fueron la mosca depredadora de las ninfas Salpingogaster nigra Schiner (Diptera: Syrphidae), ácaros parasitarios de los adultos (Acari: Erythraeidae) y hongos de varios géneros. Aunque Z. carbonaria sincroniza su ciclo de vida con las lluvias del primer semestre, no se detectó un p...

“…Entomopathogenic nematodes can be included in integrated pest management programs to M. spectabilis. (Distant, 1909) (Hemiptera: Cercopidae) can seriously limit forage production, and according to Holmann;Peck (2002), the production of meat or milk by cattle left to graze in pastures heavily infested with spittlebugs (50 adults/m 2 ) can decrease up to 54%, and the production cost can increase up to 30% because of this infestation level.…”

Virulence of entomopathogenic nematodes (Rhabditida: Steinernematidae, Heterorhabditidae) to spittlebug Mahanarva spectabilis (Hemiptera: Cercopidae)

et al. 2014

The spittlebug can seriously limit the production of forage, and the use of chemical products to control insect pests is costly and can harm the environment. Thus, there is a need to reduce the reliance on chemical agents by developing new strategies. The virulence of nine strains of entomopathogenic nematodes (EPNs) to spittlebugs was investigated under laboratory and greenhouse conditions. Fourth/fifth-instar nymphs of Mahanarva spectabilis were exposed to EPNs in the laboratory and the most virulent strains were applied on the nymphs in the greenhouse at concentrations of 2,000 and 4,000 EPNs/mL. The efficacy of the pathogenic agent was confirmed by the dissection of dead hosts. All the tested strains were pathogenic to the M. spectabilis nymphs in laboratory, particularly Steinernema carpocapsae, S. feltiae, S. riobrave and Heterorhabditis amazonensis RSC1, each of which caused nymph mortality higher than 80%. The concentration did not influence the efficiency of the strains, and those selected in the laboratory had similar efficiency in the greenhouse, except for S. carpocapsae, which was not as effective as the others. Entomopathogenic nematodes can be included in integrated pest management programs to M. spectabilis.
