| meiotic chromosomes and nucleolar behavior in testicular cells of the grassland spittlebugs deois flavopicta, mahanarva fimbriolata and notozulia entreriana (hemiptera, auchenorrhyncha). | spittlebugs annually infest pastures and cause severe damage, representing a serious problem for the tropical american beef cattle industry. spittlebugs are an important biotic constraint to forage production and there is a lack of cytogenetic data for this group of insects. for these reasons, we conducted this work, in which the spermatogenesis and nucleolar behavior of deois flavopicta, mahanarva fimbriolata and notozulia entreriana were studied. the males possessed testes in the shape of a "b ... | 2010 | 21637477 |
| warm-season (c4) turfgrass genotypes resistant to spittlebugs (hemiptera: cercopidae). | screening for resistance to insect pests is one of the early stages of grass breeding programs. pasture spittlebugs are sap-sucking insects that potentially cause severe damage to turfgrasses, including the loss of functional quality and perenniallity. the brazilian flora has a large number of grass species with wide morphological variability and adaptability to different soil and climate conditions that can potentially be used as lawns. however, no study has screened turfgrass genotypes for res ... | 2016 | 27329631 |
| the first assess of the haplotypes from coi gene sequences in species of spittlebugs (cicadomorpha: hemiptera) and aquatic true bugs (gerromorpha and nepomorpha: hemiptera) in brazil. | we made the first analysis of the coi gene sequences of 22 species of spittlebugs and aquatic true bugs sampled in são paulo state (brazil) and used this information to determine the variability within these groups. considering each codon position, we observed that the third base was the most variable, and the first base was the most conserved. among species, mahanarva fimbriolata and deois flavopicta had the greatest genetic distance (0.181), and notozulia entreriana and mahanarva sp had the sm ... | 2013 | 24301909 |
| description of the immature stages and new host plant records of deois (deois) mourei (berg) (hemiptera: cercopidae), a species newly recorded from argentina and paraguay. | deois (deois) mourei cavichioli & sakakibara (hemiptera: cercopidae) is recorded for the first time from argentina and paraguay. the eggs and immature stages of the species are described and illustrated; the main characters that distinguish instars are body size, color, number of flagellomeres, and number of tibial and metatarsomere spines. a key for identification of nymphs of d. (d.) mourei and a key to differentiate nymphs of the sympatric species d. (d.) mourei and notozulia entreriana berg ... | 2016 | 27615941 |
| descriptions of the immature stages and new host plant records of notozulia entreriana (berg) (hemiptera: cercopidae) pests of grasses in subtropical areas of the americas. | notozulia entreriana (berg) (hemiptera: cercopidae) is one of the most common spittlebugs inhabiting the subtropical region of the america, inflicting important economic damage to grass crops. the immature stages are described and illustrated; the main characteristics that distinguish instars are the body size, color, number of flagellomeres, and number of tibial and metatarsomere spines. a key for identification of nymphs is provided as a tool to develop field studies. nine host plants, all be ... | 2016 | 27394613 |
| ultrastructure and redescription of notozulia entreriana (berg) (hemiptera: cercopidae). | the ultrastructure of the spittlebug notozulia entreriana (berg) is presented. the study resulted in 32 scanning electron microscope photos, with detailed species description. | 2008 | 19061040 |
