“…This interaction is particularly relevant for eradication because it can enhance program effectiveness by increasing the beneÞt-to-cost ratio. For example, mating disruption with pheromone application can be an effective, density-dependent tactic at low population densities, but is generally ineffective at higher densities because of visual mate location (Roelofs et al 1970, Cardé and Minks 1995, Sharov et al 2002, Yamanaka 2007. Insecticide applications or host removal are both density-independent tactics that can be used at higher pest densities, but removing a sufÞcient number of individuals to drive a population below an Allee threshold may not be cost-effective or practical.…”

Invasive species increasingly threaten ecosystems, food production, and human welfare worldwide. Hundreds of eradication programs have targeted a wide range of nonnative insect species to mitigate the economic and ecological impacts of biological invasions. Many such programs used multiple tactics to achieve this goal, but interactions between tactics have received little formal consideration, specifically as they interact with Allee dynamics. If a population can be driven below an Allee threshold, extinction becomes more probable because of factors such as the failure to find mates, satiate natural enemies, or successfully exploit food resources, as well as demographic and environmental stochasticity. A key implication of an Allee threshold is that the population can be eradicated without the need and expense of killing the last individuals. Some combinations of control tactics could interact with Allee dynamics to increase the probability of successful eradication. Combinations of tactics can be considered to have synergistic (greater efficiency in achieving extinction from the combination), additive (no improvement over single tactics alone), or antagonistic (reduced efficiency from the combination) effects on Allee dynamics. We highlight examples of combinations of tactics likely to act synergistically, additively, or antagonistically on pest populations. By exploiting the interacting effects of multiple tactics on Allee dynamics, the success and cost-effectiveness of eradication programs can be enhanced.

“…Roelofs et al (1970) have calculated that, for certain moth species, a ratio of 5 traps to every 'calling' female is needed to trap sufficient males to obtain a 95% reduction in female fecundity. A male moth can fertilize more than one female and as a result a very high proportion of males would have to be removed from the population before the fecundity of the females starts to be affected.…”

“…Thus, it seems advantageous to initiate mass trapping before beetles swarm in the spring and have time to build aggregations that can compete with traps for attraction of dispersing beetles. In moths, reproduction can occur despite the high trapping efficiency suggested by the model because male moths may mate with females before being trapped (Roelofs et al, 1970).…”

“…Previous theoretical attempts at determining the effectiveness of pheromone mass trapping have used population dynamic models (Knipling and McGuire, 1966;Roelofs et al, 1970;Beroza and Knipling, 1972;Nakasuji and Fujita, 1980;Nakamura, 1982;Barclay, 1984Barclay, , 1988Fisher et al, 1985;Barclay and Li, 1991). These models are mathematically complex and make several assumptions about population survival and mating rates as well as attraction rates to pheromone traps, which limits their application.…”

Abstract--A spatial-temporal model for personal computers is developed that simulates trapping of an insect population based on trap and population parameters that can be varied independently. The model allows individual "insects" to move forward at any step size with right or left turns within any specified angle taken at random. The x and y axes of the area within which insects move can be varied as well as the number of insects, their flight speed, and the duration of the control period. In addition, the number of pheromonebaited traps, their placement in a grid or at random (with a variable degree of spacing), and their effective catch radius (proportional to pheromone release rate) can also be varied. Simulations showed that catch was similar regardless of whether traps were placed in a grid or practically at random (random placement but no traps were allowed to overlap in their effective catch radii). Iterative equations were developed for computer that can rapidly obtain values that correspond to the mean results from the slower simulation model. Based on a set of input parameters, the equations determine the percentage of the population that should be caught during a specified time, the time required to catch a specified proportion of the insects, and the number of traps necessary to catch the population proportion in the time period. The effects of varying the number of insects, flight speed, trap radius, and number of traps on the percent control or time to catch all insects are presented. Population control of the bark beetle Ips typographus was simulated using realistic pheromone trap and population parameters. A discussion of insect and bark beetle (Coleoptera: Scolyfidae) population control using pheromone traps is presented.
