“…Without greater knowledge on the local dispersal distance of Philaenus spumarius, the main vector of X. fastidiosa in Apulia (Saponari et al 2014b), and how this translates into olive tree infection, we assume that the mean dispersal distance, b, is 100 m (Blackmer et al 2004). It should be noted that a normalizing constant is not required for infection spread.…”

Modelling the spread and control of Xylella fastidiosa in the early stages of invasion in Apulia, Italy

Xylella fastidiosa is an important plant pathogen that attacks several plants of economic importance. Once restricted to the Americas, the bacterium, which causes olive quick decline syndrome, was discovered near Lecce, Italy in 2013. Since the initial outbreak, it has invaded 23,000 ha of olives in the Apulian Region, southern Italy, and is of great concern throughout Mediterranean basin. Therefore, predicting its spread and estimating the efficacy of control are of utmost importance. As data on this invasive infectious disease are poor, we have developed a spatially-explicit simulation model for X. fastidiosa to provide guidance for predicting spread in the early stages of invasion and inform management strategies. The model qualitatively and quantitatively predicts the patterns of spread. We model control zones currently employed in Apulia, showing that increasing buffer widths decrease infection risk beyond the control zone, but this may not halt the spread completely due to stochastic long-distance jumps caused by vector dispersal. Therefore, management practices should aim to reduce vector longdistance dispersal. We find optimal control scenarios that minimise control effort while reducing X. fastidiosa spread maximally-suggesting that increasing buffer zone widths should be favoured over surveillance efforts as control budgets increase. Our model highlights the importance of non-olive hosts which increase the spread rate of the disease and may lead to an order of magnitude increase in risk. Many aspects of X. fastidiosa disease invasion remain uncertain and hinder forecasting; we recommend future studies investigating quantification of the infection growth rate, and short and long distance dispersal.Keywords Buffer zone Á CoDiRO Á Olea europaea Á Olive quick decline syndrome Á Pierce's disease Á X. fastidiosa Electronic supplementary material The online version of this article

“…Although we only tested rabbit IgG as a termite mark, there are other highly specific proteins and protein-based ELISAs that could be used for termite dispersal studies. For example, rabbit IgG and chicken IgG marks have been used for MRR-type studies to simultaneously examine the intercrop dispersal of the convergent lady beetle, Hippodamia convergens Guérin-Méneville (Hagler and Naranjo, 2004) and flight behavior of glassy-winged sharpshooter, Homalodisca vitripennis Germer (Blackmer et al, 2004). These distinct proteins could prove useful in combination for termite dispersal studies requiring multiple markers.…”

“…Hagler et al (1992) were the first to show that it is feasible to mark arthropods with a foreign protein such as rabbit immunoglobulin G (IgG) that is then identified by a sensitive protein-specific enzyme-linked immunosorbent assay (ELISA). Since then, IgG marks have been applied to study the dispersal characteristics of a wide variety of insects (DeGrandi-Hoffman and Hagler, 2000;Hagler et al, 2002;Hagler and Naranjo, 2004;Blackmer et al, 2004;Peck and McQuate, 2004;Buczkowski and Bennett, 2006). Recently, Buczkowski et al (2007) successfully used reagent grade rabbit IgG as a mark to examine trophallaxis and feeding relationships in the eastern subterranean termite, Reticulitermes flavipes (Kollar), under laboratory conditions.…”

Studies were conducted to investigate the feasibility of marking the southwestern desert subterranean termite, Heterotermes aureus (Snyder), with rabbit immunoglobulin G (IgG) protein for mark-release-recapture (MRR) and mark-capture type studies. Qualitative laboratory studies were conducted to determine how long reagentgrade rabbit IgG is retained on or in H. aureus that were marked either externally with a topical spray, internally by feeding them a rabbit IgG-marked food source, or both internally and externally (double marked). Marked termites were detected by an anti-rabbit IgG enzyme-linked immunosorbent assay. Data indicated that the termites retained the mark for at least 35 days, regardless of the marking procedure. A second series of laboratory studies were conducted to determine how fast H. aureus acquire the mark after feeding on cardboard bait that was either sprayed or soaked in different formulations of rabbit IgG. The IgGs tested were a highly purified and costly reagent grade IgG at 5.0 mg/ml and a less pure and less costly technical grade rabbit IgG at 1.0 mg/ml. The results showed that termites acquired both marks equally well after exposure to the soaked cardboard treatment. The advantages and limitations of protein marking termites with rabbit IgG for MRR or mark-capture termite studies are discussed.

Mark-capture dispersal studies were conducted to investigate the feasibility of marking the southwestern desert subterranean termite, Heterotermes aureus (Snyder) with rabbit immunoglobulin G (IgG). In turn, short-range dispersal patterns of H. aureus were measured across a 20-m diameter desert landscape at three distinct field locations. Each location consisted of 51 termite feeding stations containing corrugated cardboard. The central feeding station (CFS) at each location was impregnated with rabbit IgG. A circular grid was then constructed around each CFS that consisted of 50 additional unmarked cardboard feeding stations strategically placed around the CFS at distances of 1.5, 2.0, 4.0, 7.0 or 10.0 m. Termites self-marked with rabbit IgG by feeding on the marked bait. The CFS and the 50 peripheral feeding stations were sampled for marked termites twice at each location 17-65 days after the marked bait was placed at the CFS to determine the spatial dispersal patterns of H. aureus within each research grid. Termites that self marked by feeding on rabbit IgG marked bait were detected by an anti-rabbit IgG enzyme-linked immunosorbent assay (ELISA). Generally, the CFSs contained the highest frequency of marked termites with 28.0% of the individuals assayed from the CFSs containing rabbit IgG. Over the course of the study, 39 of the unmarked peripheral feeding stations contained at least one marked termite. Of the termites assayed from the peripheral stations (n = 2,955), 124 or 4.2% of the individuals contained the mark. The average distance traveled by the marked termites collected at the peripheral feeding stations was 5.7 ± 3.3 m from the CFSs. We also examined single nucleotide polymorphisms (SNPs) from termites collected at each field site. Data indicated that each field site were genetically distinct and therefore non-related termites. We discuss the advantages and limitations of marking termites with rabbit IgG for dispersal studies.
