“…In ecological theory, when one species show a competitive advantage against others in the same environmental conditions, the advantage could be attributable to the better ability of the more advantageous species to fit to the environment (Reitz & Trumble, 2002; Roush & Daly, 1990), also known as a fitness advantage. The environmental factors for arthropods includes temperature, food, pesticides, where these factors affect the competition and distribution of arthropods differently under different conditions.…”

Adaptation of acaricide stress facilitates Tetranychus urticae expanding against Tetranychus cinnabarinus in China

The two‐spotted spider mite, Tetranychus urticae, and the carmine spider mite, Tetranychus cinnabarinus, are invasive and native species in China, respectively. Compared with T. cinnabarinus, T. urticae has expanded into most parts of China and has become the dominant species of spider mite since 1983, when it was first reported in China. However, the mechanism of the demographic conversion has not been illuminated. In this study, one T. urticae field population and one T. cinnabarinus field population were isolated from the same plant in the same field, and the toxicological characteristics were compared between these two species. Laboratory bioassays demonstrated that T. urticae was more tolerant to commonly used acaricides than T. cinnabarinus. The activities of detoxification enzymes were significantly greater in T. urticae, and the fold changes of enzymes activities in T. urticae were also greater following exposure to acaricides. Furthermore, more metabolism‐related genes were upregulated at a basal level, and more genes were induced in T. urticae following exposure to acaricides. The comparison of proteins and genes between both species led credence to the hypothesis that T. urticae was more resistant to acaricides, which was the reason explaining the expansion of invasive T. urticae against native T. cinnabarinus. Laboratory simulation experiments demonstrated that following the application of acaricides, the composition of a mixed T. urticae/T. cinnabarinus population would change from a T. cinnabarinus‐dominant to a T. urticae‐dominant population. This study not only reveals that T. urticae possesses stronger detoxification capacity than its sibling species T. cinnabarinus, which facilitated its persistent expansion in China, but also points to the need to accurately identify Tetranychus species and to develop species‐specific management strategies for these pests.

“…Such costs may arise from disruptive effects of the resistance mechanisms on pre-existing functions, or from overproduction of detoxification enzymes diverting energy normally allocated to the life history traits (Uyenoyama, 1986;Lenski, 1988;Roush & Daly, 1990;Carrière et a!., 1994). The change in frequency of a major resistance allele may profoundly influence the genetic properties of a population.…”

Under selection for insecticide resistance, the spread of a major resistance allele that has strong pleiotropic effects on life history characters will affect the genetic architecture of fitness. A model is developed showing that the spread of such an allele induces a change in the mean and in the additive genetic variance (heritability) of the life history characters, and in the genetic covariance (correlation) between these characters. The model was tested using a quantitative genetic study that compared, in a lepidopteran species (Choristoneura rosaceana), the genetic architecture of diapause propensity and larval weight within and among insecticidefree and insecticide-treated populations from the same geographical area. Significant genetic correlations between resistance to the insecticides and the life history traits were found within the populations, suggesting that the resistance allele(s) has pleiotropic effects on the life history characters. As resistance develops from an initial value of zero, the model predicts a positive relationship between the degree of resistance within the populations and, (1) the magnitude of the fitness costs, (2) the heritability of the life history traits, and (3) the absolute value of the genetic correlations between pairs of life history traits. All these predictions were confirmed. Moreover, the evolution of resistance apparently affected the environmental variance in larval weight. Hence, the novel evolution of insecticide resistance appears to result in major changes in the genetic architecture of fitness, which may limit to some extent the colonization of insecticide-treated habitats.

“…Studies on the evolution of insecticide resistance have allowed the impact of selection on the genetic structure of populations to be investigated in circumstances where the selective agent, the insecticide, is clearly defined (Roush & McKenzie, 1987;Mallet, 1989; Roush & Daly, 1990;Macnair, 1991;McKenzie & Batterham, 1994).…”

Selection at the diazinon resistance locus in overwintering populations of Lucilia cuprina (the Australian sheep blowfly)

In excess of 70 per cent mortality is observed during the overwintering stage of the life cycle of L. cuprina. The mortality is selective in the absence of a fitness modifier; phenotypes resistant to diazinon overwinter less successfully than susceptibles. In the presence of the modifier the overwintering success of all genotypes is similar. The effect is dominant. Laboratory and field experiments show that selection against resistant individuals increases with time in arrested development. The relevance of these results to the evolution of insecticide resistance is discussed.
