“…The volume and shape of the pheromone plume (Mafra‐Neto & Cardé, ) thus determines the attraction range of pheromone traps. It is important to know the attraction range of pheromone traps to optimize the setting of pheromone trap networks (Manoukis et al ., ) and infer the sampling area (i.e. the portion of the landscape where the target species can be detected) (Kriticos et al ., ).…”

1 Pheromone traps are widely used for monitoring or managing insect pest populations. However, it is important to know their range of attraction to optimize the setting of pheromone trap networks. 2 We propose an easy method based on the use of pairs of adjacent traps located at decreasing distance from each other. The range of attraction is deduced from the observation of reduced trap capture when the attraction range of two adjacent traps starts overlapping. The relationship between the relative trap capture and the distance between paired traps is fitted with a logistic curve. 3 To empirically test these predictions, we conducted trapping experiments with the beetle Monochamus galloprovincialis, the insect vector of the pine wood nematode. Fifteen pairs of traps separated by 25 to 300 m, in France, and 18 pairs of traps distant from 25 to 400 m, in Portugal, were installed in maritime pine plantation landscapes. 4 In both countries, the relative percentage of capture per trap per week was best fitted by a logistic model with two parameters. The estimated attraction ranges were 92 m (confidence interval = 62-211 m) in France and 123 m (confidence interval = 64-491 m) in Portugal. 5 The interference between paired traps thus provides a simple and robust method for estimating the attraction range of pheromone traps.

“…MRR, MR, and MC studies can be used for assessing (seasonal) dispersal [31,70,73,[79][80][81][82] or estimating population sizes [83,84] and can assist in the development of preventative strategies, better targeted control measures or prediction models [85]. MR and MRR studies can also be useful for determining trapping parameters in the development of monitoring [30,[86][87][88] and mass trapping strategies [89]. Marking methods can further be applied to (easily) distinguish treatment groups or strains in laboratory, semi-field, or field trials.…”

The marking of Drosophila suzukii can be an important instrument for studying the ecology and behaviour of this economically important fruit pest, aiding the development of new Integrated Pest Management (IPM) tools or strategies. There is, however, a need for a cost-effective methodology that provides an easily detectable and stable mark. Whereas fluorescent pigment powders are often used in entomological research, the pigments (series, dyes), application techniques, or doses need to be evaluated for each studied species in terms of their efficacy and possible adverse effects on the performance of the insect. The effectiveness of different application techniques and dyes (RadGlo ® TP-series) and their effect on the survival of adult D. suzukii were investigated in the laboratory. Furthermore, the influence of the marking on the behaviour of the flies was examined in laboratory trap assays (olfaction) and a field recapture study (general orientation). The persistence and detectability of the marks was evaluated both on living flies (for different application techniques) and dead flies under trapping/storage conditions. The use of fluorescent powders to mark D. suzukii flies yielded a clearly detectable and highly persistent mark, without any adverse effects on the survival and behaviour of the flies. Insects 2020, 11, 152 2 of 20The spotted wing Drosophila, Drosophila suzukii Matsumura (Diptera: Drosophilidae), native to Asia [5][6][7], has become a worldwide invasive pest of soft-skinned fruit crops over the last decade [8][9][10][11][12][13][14]. Studies on the ecology and behaviour of the species can yield new insights allowing the improvement or development of management strategies. Various methods for marking D. suzukii flies have been proposed and further optimised. An immunomarking technique (i.e., the use of proteins as markers and detection by enzyme-linked immuno-sorbent assays (ELISA) [15]) for both topical application and acquisition of residues on leaves was tested and optimised by Klick et al. in a series of laboratory and semi-field experiments [16]. What makes this technique unique is that vast areas can be sprayed with inexpensive proteins and that detection by ELISA is fairly sensitive to the acquisition of leaf residues. The disadvantages of immunomarking are the possibility of both false positives and false negatives [17], the need for individual analyses of specimens, and the costs and labour required for detection. Trace elements and stable isotopes can be administered to plants to act as systemic markers for herbivorous insects, an approach that was evaluated for D. suzukii with Rb and 15 N. [18]. The added value of these systemic markers lies in the fact that larvae are self-marked while developing inside the host fruits, enabling the linkage of captured adults to their source of larval development [18]. Methods of self-marking are particularly interesting for MC studies in which whole areas or plants are marked, instead of marking the (captured/reared) insects before release. For MR and M...

“…MED-FOES 25, 27 is an agent-based simulation explicitly modeling the eradication of a population of Medflies under inundative sterile male releases (sterile insect technique or SIT) and other interventions, such as increased trapping and foliar sprays. A MED-FOES simulation models a single non-spatial population, starting from a given population size and age distribution, tracking the number of individuals through time until the last fly (Agent) dies and the population is eliminated.…”

“…In this paper, predicted quarantine length (PQL) for 11 sites in the continental United States were analyzed ( Figure 1 and Table 1) based on both the standard thermal accumulation degree day method 26 as well as the MED-FOES ABS 27 . Seasonal variation dominates quarantine duration, so we aggregated the PQL values for each day of the year (Jan. 1, Jan. 2, etc.)…”

Invasions by pest insects pose a significant threat to agriculture worldwide. In the case of Ceratitis capitata incursions on the US mainland, where it is not officially established, repeated detections are followed by quarantines and treatments to eliminate the invading population. However, it is difficult to accurately set quarantine duration because non-detection may not mean the pest is eliminated. Most programs extend quarantine lengths past the last fly detection by calculating the amount of time required for 3 generations to elapse under a thermal unit accumulation development model (“degree day”). A newer approach is to use an Agent-Based Simulation (ABS) to explicitly simulate population demographics and elimination. Here, predicted quarantine lengths for 11 sites in the continental United States are evaluated using both approaches. Results indicate a strong seasonality in quarantine length, with longer predictions in the second half of the year compared with the first; this pattern is more extreme in degree day predictions compared with ABS. Geographically, quarantine lengths increased with latitude, though this was less pronounced under the ABS. Variation in quarantine lengths for particular times and places was dramatically larger for degree day than ABS, generally spiking in the middle of the year for degree day and peaking in second half of the year for ABS. Analysis of 34 C. capitata quarantines from 1975 to 2017 in California shows that, for all but two, quarantines were started in the second half of the year, when degree day quarantine lengths are longest and have the highest uncertainty. For a set of hypothetical outbreaks based on these historical quarantines, the ABS produced significantly shorter quarantines than degree day calculations. Overall, ABS quarantine lengths were more consistent than degree day predictions, avoided unrealistically long values, and captured effects of rare events such as cold snaps.
