“…It also is argued that the withdrawal of insecticide selection pressure led to diversion of resources from the fitness traits or alteration of the normal functioning of target site [28]. Reversion of resistance has been previously reported in a variety of insect pests against different insecticides [15,52]. Discontinued insecticide application with instable resistance portfolio (on discontinuing the selection pressure) may prove helpful to prolong the effective life span of such chemicals in the field.…”

“…Because this hypothesis had not heretofore been investigated, we did so using as a model system the obliquebanded leafroller (OBL), Choristoneura rosaceana Harris, a tortricid species that has recently developed resistance to several synthetic insecticides (Reissig et al 1986;Carrière et al 1994Carrière et al , 1996Lawson et al 1997;Smirle et al 1998;Pree et al 2001). In addition, we also examined the impact of insecticidal resistance on the reproductive success of OBL males by comparing their mating success as well as the size of the spermatophores they produced on successive matings.…”

This study reports on the impact of insecticidal resistance on the diel periodicity of the calling behaviour and pheromone production of different-aged virgin females of the obliquebanded leafroller (OBL), Choristoneura rosaceana. While both resistant (R) and susceptible (S) females initiated calling on the first night following emergence, the periodicity of the calling behaviour, as determined by the mean onset time of calling (MOTC) and the mean time spent calling (MTSC) over the first six nights of calling, differed between the two strains. R females started calling significantly later in the night. However, as the MOTC of R females advanced with age but did not do so in S individuals, the difference between strains was more pronounced in younger than older females. Furthermore, R females spent less time calling than S individuals. However, the MTSC increased as a function of age in both R and S females, so the difference between strains remained fairly constant for each night of calling. The major component of OBL sex pheromone, the Z11-14 : Ac, determined at peak calling activity, significantly declined with female age. Overall, pheromone production was lower in R females than in S females, with the difference being more pronounced in younger than in older individuals. Thus, resistant females may have a lower mating success. The mating success of both R and S strain males did not vary with the number of previous matings acquired. With regard to males, although there was a significant decline in spermatophore size with successive matings, there was no significant difference between strains. However, R males are smaller and may be disadvantaged through female choice and/or may respond differently to pheromone source compared with S individuals. If the reproductive success of both sexes is affected, this may have a profound influence on the dynamics of insecticidal resistance in the presence or absence of selection in OBL populations.

“…While a number of parasitoids can attack these leafroller species, parasitism levels are typically low in conventional orchards (Brunner and Beers, 1990). The use of OP insecticides in the spring and summer for these pests further destabilizes secondary pest populations (Beers et at., 1998) and has selected for resistance in some populations (Smirle et at., 1998). Selective control of leaf rollers is possible with Bacillus thuringiensis (Bt) but the level of control is variable (Brunner, 1994).…”

Areawide Pest Management: Theory and Implementation

The 5-year CAMP (Codling Moth [Cydia pomonella] Areawide Management Program) was the first of the areawide programmes initiated by USDA. The goal of this programme was to implement, assess, research and educate the industry about promising new IPM technologies. CAMP was highly successful in fuelling the rapid adoption of a new paradigm in orchard pest management that resulted in significant reductions in fruit injury using nearly 80% less broad-spectrum insecticides. Several factors have contributed to the success of the CAMP programme. These can be grouped into two categories: (i) operational - the availability of several effective and selective tactics for both the key and secondary pests backed by technical support; and (ii) organizational - well-funded, coordinated programmes directly involving growers, researchers, industry leaders and governmental administrators. The lesson learned from the CAMP programme is that pest management is similar to rocket science and requires attention, experience and skill to be effective. Dissemination of knowledge and coordination of actions by individual growers have been shown to improve pest management, and offer tremendous benefits to society. Future efforts should focus on how similar, grower-based organizations can be developed and sustained.
