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.

“…For more information about the parasitoid data collected, see Banks, Banks, Cody, Hoddle, and Meade [1]. The reproductive and developmental biology of H. vitripennis depends on climatic conditions, especially temperature [20], so temperature is an important part of the GWSS model. The daily minimum and maximum temperatures from January 1, 2002 to December 31, 2012 in Riverside, CA were downloaded from an automated weather station, CIMIS 44, located at UCR Ag.…”

“…The glassy-winged sharpshooter (GWSS), Homalodisca vitripennis (Germar) (Hemiptera: Cicadellidae), is a xylem-feeding leafhopper native to the southern United States from Florida to Texas and northeastern Mexico [18]. H. vitripennis has a large degree of agricultural importance, because it vectors a xylem-dwelling bacterium, Xylella fasitidiosa, which causes a variety of often lethal plant diseases (e.g., Pierce's disease of grapes) [19,20].…”

“…vitripennis exhibits high invasion potential and is a signicant pest outside of its native range, including California [20], Hawaii, the Cook Islands, Easter Island, and French Polynesia [13,14]. In particular, after invading California in 1990, H. vitripennis has represented a major economic threat to the wine, table, and raisin grape industries, because it was implicated in a signicant increase of the lethal and incurable grape malady, Pierce's disease [18,20]. This disease costs approximately $104 million per year in crop damage and resources devoted to mitigating this threat [21].…”

“…The goal of this project is to determine whether abiotic factors such as temperature were responsible for observed population trends (i.e., density independent population regulation). The reproductive and developmental biology of H. vitripennis is strongly inuence by environmental factors, especially temperature [20]. In an earlier investigation [1] we developed a system of ordinary dierential equations (ODEs) to investigate the cause of this observed decrease in H. vitripennis populations over time.…”

The glassy-winged sharpshooter, Homalodisca vitripennis, is an invasive pest which presents a major economic threat to grape industries in California, as well as Texas [22] and other wine growing regions, because it spreads a disease-causing bacterium, Xylella fastidiosa. We continue an earlier investigation [1] into a long-term phenological decline of H. vitripennis densities by studying a system of delayed dierential equations (DDEs) and analyzing aggregate population data for H. vitripennis from a 10-year study in which biweekly monitoring of H. vitripennis populations decreased signicantly. These data present several challenges for modelers. First, they involve truly aggregate population level sampling and hence cannot properly be treated as ordinary longitudinal time series data corresponding to individual level models. The appropriate modeling involves estimation of probability distributions for parameters rather than estimation of the dynamic parameters themselves. Moreover, our analysis reveals that the correct corresponding statistical models involve errors that are observation size dependent (e.g., relative errors should be employed in statistical models). We use these data to test whether DDEs are useful in modeling the observed H. vitripennis population decline. To do this, we perform an analysis of variance (ANOVA) type test comparing the glassy-winged sharpshooter (GWSS) model with delay to the model without delay [1]. The model is t to the aggregate H. vitripennis data using iterative reweighted weighted least squares (IRWLS) by estimating probability densities over the delay and one of the birthrate parameters. Results indicate that a positive delay provides improvement with a signicance level of p < 0:005.
