“…The relationship between dispersal rates and host plant quality was investigated for the glassy‐winged sharpshooter, Homalodisca vitripennis (Germar) (Hemiptera: Cicadellidae) (Northfield et al. ). The authors reported that H. vitripennis dispersed farther from the release site when the hosts were considered of poor nutritional quality.…”

Studies designed to measure dispersal capacity of Diaphorina citri Kuwayama (Hemiptera: Liviidae) are needed to provide the epidemiological knowledge necessary to improve management of citrus huanglongbing. In this study, a mark-release-recapture technique was used to investigate whether 1) host or non-host plants of D. citri can act as barriers for dispersing insects and 2) presence or absence of young citrus leaves influence movement of D. citri towards citrus plants. The experimental field consisted of four circular and adjacent areas containing citrus trees, Citrus sinensis (L.) Osbeck cv. 'Hamlin', planted in concentric circles at 18, 24 and 30 m from the release centre. Insect activity was monitored by recapturing at each distance using yellow stick traps. Dense plantings of tall non-host plants of D. citri such as corn had no effect on insect dispersal towards citrus plants when compared to a shorter cover crop such as grass. In contrast, suitable host plants acted as traps decreasing movement of D. citri. Diaphorina citri dispersed at greater speeds in the absence of young leaves reaching 140 m within 6 hours after release, whereas in the presence of young leaves, individuals reached at most 60 m at 1 day after release. Results suggest that D. citri control measures may be more efficient during periods of highest vegetative activity when insects are less active. Moreover, the use of suitable host plants for D. citri as trap plants may be a potential tactic to prevent movement of insects into the crop.

“…The exponential model was chosen to verify if marked S. titanus would decrease at increasing distances from the source (treated WGV) following an exponential decay pattern. For the same reason, for each regression we calculated the median dispersal index r 0.5 (i.e., the distance where 50% of the marked individuals are found) using the negative half-life equation: r 0.5 =ln(2)/ b (Northfield et al , 2009).…”

Tracking the movement dispersion of Scaphoideus titanusThe movement dispersion of Scaphoideus titanus Ball adults from wild to cultivated 8 grapevine was studied with a novel mark-capture techniqueapplying. aA water solution of 9 cow milk (marker: casein) or chicken egg whites (marker: albumin) was applied directly onto 10 the canopy of wild grapevine more or less in close proximity (5-350 m) to at a distance from 11 vineyards ranging from 5 to 330 m.; Yyellow sticky traps were placed on the canopy of 12 grapes, and captured S. titanus adultsinsects were analyzed via an indirect ELISA for 13 markers' identification. Data were subject to exponential regression as a function of distance 14 from wild grapevine, and to spatial interpolation analyses (Inverse Distance Weighted and 15Kernel interpolation with barriers) were performedusing ArcGIS Desktop 10.1 software.; Tthe 16 influence of rainfall and time elapsed after marking on markers' effectiveness, and the 17 different dispersal patternsdispersion of males and females were also studied with regression 18 analyses. Of a total of 5417 insects analyzed for egg, 43% were positive to egg; whereas 18% 19 of 536 tested were milk-resulted marked with milkpositive. No influence of rainfall or time 20 since the marker's applicationelapsed was observed for egg-marked specimens, whereas milk-21 Introduction 33The nearctic leafhopper Scaphoideus titanus Ball (Hemiptera: Cicadellidae) was introduced 34into Europe in the late 1950s (Bonfils & Schvester, 1960) and is now widespread in many 35European countries from Portugal to Bulgaria (COST Action FA0807). This species is a 36 grapevine specialist, and develops on both wild and cultivated grapevine (Vitis spp.). It is 37 univoltine and overwinters in the egg stage, which is laid under the bark of wood 2-yrs of age 38 or more (Vidano, 1964); eggs start to hatch in the middle of May and nymphs (which include 39 five instars) are present until the end of July, whereas adults usually appear at the beginning 40 of July and are observed up to the middle of October (Vidano, 1964). S. titanus is an 41 important pest, as it is the main vector of grapevine's Flavescence dorée (FD), a disease 42 caused by 16SrV phytoplasmas (subgroups C and D) (Malembic-Maher et al., 2011). Nymphs 43 from the 3 rd instar on acquire phytoplasmas by feeding on infected plants (acquisition access 44 period, AAP), and following a latency access period (LAP) of 4-5 weeks they become adults 45 and able to transmit FD to healthy plants (IAP) (Bressan et al., 2005). Since FD is a cause of 46 great economic losses, insecticidal sprays against S. titanus are mandatory in Italy: active 47 ingredients include neonichotinoids, organophosphates, etofenprox, and natural pyrethrum, 48 the latter in organic farming (Lessio et al., 2011a Marking methods used in entomology include fluorescent dusts (Garcia-Salazar & Landis, 55 1997; Takken et al., 1998; Skovgard, 2002), radioisotopes (Hagler & Jackson, 2001), and 56immunomarking (Hagler & Jackson, 2001; Jones et al.,...

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.
