Geographic Distribution and Relative Abundance of the Invasive Glassy-Winged Sharpshooter: Effects of Temperature and Egg Parasitoids

Climate warming effects on grape and grapevine moth (Lobesia botrana) in thePalearcticregion

“…1). PBDM modelling of this level of complexity is facilitated by the fact that the same dynamics model are used for all species and the same forms for the biodynamic models reoccur for analogous processes in the life histories of all species across trophic levels (Gutierrez & Baumgärtner, 1984;Gutierrez et al, 2011;Gutierrez & Ponti, 2013). The development of PBDMs is facilitated by their modular structure enabling different combinations of species to be implemented in model runs using simple true-false Boolean variables, allowing the system to be viewed from the perspective of any of the interacting species (Gutierrez & Baumgärtner, 1984;Gutierrez & Ponti, 2013).…”

“…In the best case, PBDMs can be tested against field data (Rodríguez et al, 2013). The PBDM approach in a GIS context has been applied to many agroecological systems (Gutierrez et al, 2006(Gutierrez et al, , 2010(Gutierrez et al, , 2011(Gutierrez et al, , 2016Ponti et al, 2014) and has provided considerable insights concerning the biology at the local and regional level useful in developing pest management practices and policy (see below). However, despite their considerable utility, we caution that all models including PBDMs are incomplete.…”

“…1): the vine mealybug Planococcus ficus, its two parasitoids Anagyrus pseudococci and Leptomastidea abnormis, and the coccinellid predator Cryptolaemus (Gutierrez et al, 1985;Wermelinger et al, 1991) and (b) the linkage of L. botrana life-stages including diapause induction and termination . Note the linkages of two vascular feeding Hemiptera: the vine mealybug and the glassy winged sharpshooter (GWSS) and their natural enemies and the transmission of the Pierce's disease bacterium Xylella fastidiosa by GWSS (Gutierrez et al, , 2011.…”

“…montrouzieri , as well as the glassy winged sharpshooter (GWSS) Homalodisca vitripennis that vectors the pathogenic bacterium Xylella fastidiosa causing Pierce's disease and the two egg parasitoids Gonatocerus ashmeadi and G. triguttatus that attack it (Gutierrez et al, 2011).…”

Calculation and Thematic Mapping of Demographic Parameters forHomalodisca vitripennis(Hemiptera: Cicadellidae) in California

“…The utility of laboratory-derived demographic parameters to model pest or natural enemy distributions using longterm weather records for an area of interest has been shown to refiect the known distribution of mymarid egg parasitoids of H. vitripennis Hoddle 2006b, 2007). In the absence of démographie data across a variety of temperatures for H. vitripennis, climate-driven ecological niche models (Hoddle 2004) or weather-driven physiologically based demographic models have been used to predict distributions of this pest in Galifornia (Gutierrez et al 2011) and elsewhere (Hoddle 2004).…”
