“…Murraya paniculata and C. sinensis 'Marrs' were the hosts that supported the largest D. citri populations, an aspect that coincides with reports of several authors who commented that this is because these rutaceous taxa grow new shoots and leaves continuously, and thereby provide food and oviposition sites for the insect (Tsai et al 2002;Fernández & Miranda 2005b;Ortega et al 2013). In contrast, on C. limetta, C. sinensis 'Selection 8', and C. paradisi trees, adult densities were low despite the availability of shoots (Ortega et al 2013).…”

Symmetry Breaking in Interspecific Drosophila Hybrids Is Not Due to Developmental Noise

2006

Hybrids from crosses of different species have been reported to display decreased developmental stability when compared to their pure species, which is conventionally attributed to a breakdown of coadapted gene complexes. Drosophila subobscura and its close relative D. madeirensis were hybridized in the laboratory to test the hypothesis that genuine fluctuating asymmetry, measured as the within‐individual variance between right and left wings that results from random perturbations in development, would significantly increase after interspecific hybridization. When sires of D. subobscura were mated to heterospecific females following a hybrid half‐sib breeding design, F1 hybrid females showed a large bilateral asymmetry with a substantial proportion of individuals having an asymmetric index larger than 5% of total wing size. Such an anomaly, however, cannot be plainly explained by an increase of developmental instability in hybrids but is the result of some aberrant developmental processes. Our findings suggest that interspecific hybrids are as able as their parents to buffer developmental noise, notwithstanding the fact that their proper bilateral development can be harshly compromised. Together with the low correspondence between the covariation structures of the interindividual genetic components and the within‐individual ones from a Procrustes analysis, our data also suggest that the underlying processes that control (genetic) canalization and developmental stability do not share a common mechanism. We argue that the conventional account of decreased developmental stability in interspecific hybrids needs to be reappraised.

“…Vector host choice (Blua and Perring 1992;McElhany et al 1995;Alvarez et al 2007) and within-host feedingsite preference (Tsai et al 2002;Marucci et al 2004) can influence patterns of vector-borne pathogen distribution and disease dynamics (McElhany et al 1995;Kilpatrick et al 2006;Sisterson 2008). Moreover, variations in feeding behaviour among species may also contribute to the existing differential transmission efficiency of vectors (Turell et al 2001;Daugherty and Almeida 2009) through governing the degree to which they are exposed to a pathogen.…”

Background matching behaviour and pathogen acquisition: plant site preference does not predict the bacterial acquisition efficiency of vectors

Arthropod-Plant Interactions

Many insect-borne pathogens are heterogeneously distributed within their hosts: therefore, a vector's within-plant distribution may be a predictor of its exposure to pathogens. In this study, we set out to quantify plant site preference, in the context of background matching, and investigated its effect on acquisition of a bacterial pathogen by its leafhopper vectors. The two green-coloured species, Graphocephala atropunctata and Draeculacephala minerva, preferred green plant tissue and artificial backgrounds whereas the brown-coloured Homalodisca vitripennis preferred brown stem tissue and backgrounds. Within-plant feeding site did not predict either the acquisition success or the number of plant-pathogenic Xylella fastidiosa cells acquired by the vectors; an 86% mortality for G. atropunctata was reported on the lignified stem tissue. Overall, H. vitripennis acquired significantly more cells than G. atropunctata. A novel artificial diet-based transmission system was used to further illustrate that the observed between-species difference in the number of cells acquired was independent of vector-host plant interactions. H. vitripennis, a less efficient vector of the bacterium X. fastidiosa on grapevines, acquired more bacterial cells than G. atropunctata, possibly due to its larger size. Contrary to previous assumptions, pathogen acquisition efficiency by the vectors did not explain their reported differences in inoculation. Vector interactions with the host during the inoculation stage should be evaluated as another determinant of X. fastidiosa transmission efficiency.

RESUMENSe evaluó el ciclo biológico, tablas de vida y capacidad de consumo de Exochomus marginipennis (LeConte) sobre el psílido asiático de los cítricos Diaphorina citri Kuwayama, vector de la enfermedad Huanglongbing (HLB). El huevo tardó 5,83 ± 0,07 días en eclosionar, mientras que la larva y la prepupa-pupa demoraron 16,4 ± 0,73 y 5,82 ± 0,33 días, respectivamente. La longevidad del adulto fue de 58,8 ± 8,33 días en promedio. La tasa de mortalidad específica (q x ) mantuvo valores bajos en los cuatro estadios larvales y prepupa, durante el estado de huevo q x se incrementó, mientras que la fecundidad (m x ) y la tasa neta de reproducción (R o ) alcanzaron valores superiores a la unidad, evidenciando con esto un incremento en la población, a pesar de la alta mortalidad del estado de huevo. La larva IV (98,8 ± 2,61) seguida de la larva III (97,60 ± 3,43) y el adulto (96 ± 2.60) son los que ejercieron una mayor depredación. La ninfa V de D. citri es el instar menos consumido. Los resultados obtenidos exhiben por vez primera el ciclo biológico de E. marginipennis bajo condiciones controladas y soportan su capacidad de depredación sobre D. citri, para su potencial integración en programas de control biológico de esta plaga.Palabras clave: Coccinellidae, psílido asiático de los cítricos, Candidatus Liberibacter spp., depredador, control biológico. Aceptado: 07 enero 2016.
