“…Al-Wahaibi (2004), based on work by Hix (2001) and Rakitov (2000Rakitov ( , 2002Rakitov ( , 2004, outlined a compound microscope method for differentiating the two species using the shape of the brochosomes deposited by females on the surface of egg masses. De Azevedo Filho and Carvalho (2005) and De Azevedo Filho et al (2008) used variation in the morphology of brochosomes (discerned using scanning electron microscopy) to produce keys to differentiate among seven and eight species of Proconiini leafhoppers occurring, respectively, on citrus and grape vines in Brazil, respectively. Other promising methodologies to identify Homalodisca eggs to species include immunological assays such as enzyme-linked immunosorbent assay (Hagler et al 2002(Hagler et al , 2003 and electrophoretic enzyme techniques such as esterase proÞling (Toscano et al 2003, Byrne andToscano 2006).…”

Morphometric and developmental aspects of the egg stage of glassy-winged sharpshooter, Homalodisca vitripennis (Germar), and Homalodisca liturata Ball were investigated. Considerable overlap exists between the two species with respect to egg length, width, and clutch size, making these variables unreliable in identifying their eggs to species. Embryonic development of the two species was observed at constant temperatures ranging from 8.7 to 40.4°C. No signs of development were observed at 8.7°C, development was aborted early in development at 11.5°C, and egg masses were desiccated at 40.4°C. For both species, rates of embryonic development increased linearly with increasing temperatures from 16.7 to 25.6°C, peaked at 31.2°C, and decreased between 32.9 and 35.0°C. Based on linear regression, the minimum thresholds for embryonic development were 12.0 and 12.6°C, and heat unit requirements were 111.4 and 104.5 degree-days for H. vitripennis and H. liturata, respectively. We quantified four physiological states of embryonic development, based on eye spots being normally developed, centrally developed, reversed, or undeveloped. The prevalence of these states did not differ significantly between the two species and comparing data from the laboratory versus the field. However, higher experimental temperatures tended to increase the prevalence of abnormally developed eye spots. Nonparasitic mortality of Homalodisca eggs in five field host plants was attributed to undeveloped-abnormally developed embryos and to the inability of first-instar nymphs to emerge from eggs. These causes of mortality varied among host plants. Eggs on mule fat tended to have a higher proportion of undeveloped-abnormally developed eggs, whereas on jojoba, Simmondsia chinensis (Link) Schneider, a higher prevalence of dead but fully developed embryos was observed inside eggs.

Sharpshooters: a review of what moves Xylella fastidiosa

et al. 2019

View full text Add to dashboard Cite

Sharpshooters (Hemiptera: Cicadellidae: Cicadellinae) and spittlebugs (Hemiptera: Aphrophoridae: Aphrophorinae) have a worldwide distribution and are often associated with many crops. Because the geographic range of sharpshooters and spittlebugs often overlaps with the range of the plant pathogenic bacterium Xylella fastidiosa, the importance of these groups of insects in spreading X. fastidiosa rises to the level of a major socioeconomic problem. Managing diseases caused by X. fastidiosa is challenging for several reasons. First, multiple sequence types of the pathogen have been identified, with sequence type affecting host plant specificity. Second, multiple vector species may be present in an agroecosystem, and the host range of vector species is often broad. Although multiple vector control options such as biological, chemical, physical and cultural controls have been described, disease control programs must take into account biological and ecological parameters of locally dominant X. fastidiosa sequence types and vector species to develop suitable control strategies. Our review demonstrates how fundamental principles of vector reproductive biology, behaviour, nutrition and population and community ecology have influenced research on insect vectors and provides insights into priority research areas.

The knowledge of the entomological fauna in productive systems is important for the agroecological management since beneficial insects are a key resource for pest management in horticultural systems. Scientific information on the biodiversity present in a given area is essential as well as the ecological function and/or feeding habits of the insects. In Alto Valle de Río Negro and Neuquén, horticultural production systems can be described as highly dependent on chemical inputs for pest management and fertilization. The aim of this study is to carry out an inventory of the biodiversity of some families of Hemiptera, Coleoptera (Curculionidae) and Hymenoptera present in peri-urban and rural farms located in Neuquén and Río Negro, respectively. Insects were collected through pitfall and sweeping net on tomato and pepper crops and the surrounding non-cultivated areas. Idiosystatus Berg (Auchenorrhyncha) was cited for the first time from Argentina. Species cited for the first time from Neuquén: Hemiptera: Auchenorrhyncha: Acanalonia chloris (Berg), Syncharina punctatissima (Signoret), Amplicephalus dubius Linnavuori, Exitianus obscurinervis (Stål), Agalliana ensigera Oman and Bergallia signata (Stål); Hemiptera: Heteroptera: Harmostes (Harmostes) prolixus Stål and Atrachelus (Atrachelus) cinereus (Fabricius); Coleoptera: Curculionidae: Hypurus bertrandi (Perris), Naupactus leucoloma Boheman, Otiorhynchus rugosostriatus (Goeze) and Sitona discoideus Gyllenhal and Hymenoptera: Xylocopa (Neoxylocopa) augusti Lepeletier and Pseudagapostemon (Neagapostemon) singularis Jörgensen. Species cited for the first time from Río Negro: Hemiptera: Auchenorrhyncha: Amplicephalus dubius Linnavuori, Amplicephalus marginellanus Linnavuori, Circulifer tenellus (Baker) and Xerophloea viridis (Fabricius); Hemiptera: Heteroptera: Tupiocoris cucurbitaceus (Spinola), Atrachelus (Atrachelus) cinereus (Fabricius), Dichelops furcatus (Fabricius) and Harmostes (Harmostes) prolixus Stål; Coleptera: Curculionidae: Naupactus xanthographus (Germar) and Hymenoptera: Diadasia pereyrae (Holmberg) and Dialictus autranellus (Vachal)
