“…Research on fitness cost effects on DDT‐resistant mosquitoes was conducted back in 1948. Several studies showed higher fitness traits in resistant strains compared with susceptible ones, and most notably a longer time for larval stages to reach pupation in the resistant strain 19…”

Insects are exposed to a variety of stress factors in their environment, and, in many cases for insect pests to agriculture, those factors include toxic chemical insecticides. Coping with the toxicity of insecticides can be costly and requires energy and resource allocation for adaptation and survival. Several behavioural, physiological and genetic mechanisms are used by insects to handle toxic insecticides, sometimes leading to resistance by constitutive overexpression of detoxification enzymes or inducing mutations in the target sites. Such actions are costly and may affect reproduction, impair dispersal ability and have several other effects on the insect's fitness. Fitness costs resulting from resistance to insecticides has been reported in many insects from different orders, and several examples are given in this mini-review.

“…A resistance allele often produces marked physiological and biochemical disruption when it first arises, placing carriers at a selective disadvantage in environments free of insecticide (Brown and Pal, 1971). The initial deleterious effects on the occurrence of a resistance allele are not necessarily reflected in all stages of the life cycle (Pimental et a!., 1951;Underhill and Merrell, 1966). Subsequent selection will favour modifications that minimize the deleterious effect of a new mutation, as is attested by the slow reversion rates of resistance in the absence of insecticides in some insect strains (Abedi and Brown, 1960;Forgash and Hansens, 1967).…”

The effect of genetic background on the fitness of diazinon resistance genotypes of the Australian sheep blowfly, Lucilia cuprina

SUMMARYLaboratory and field experimentation has shown that resistant and susceptible diazinon genotypes of flies collected from the field may have similar fitness in an environment free of diazinon. If the genetic background of resistant genotypes from the field is disrupted, the fitness of the resistant genotype declines. These results, in conjunction with previous data, indicate a modification of the genetic background in field populations following the spread of the resistance allele some ten years earlier. It is suggested that this outcome is dependent on the availability of genetic variability, the intensity of selection and the duration of insecticide usage after resistance develops.

“…Temperature has been regarded as the most influential factor for the development of T. solanivora, where the number of generations per year can vary from two (at 10 °C) to ten (at 25 °C) . However, the shorter developmental time observed for the multiple‐resistant insects in our study is an exceptional case in life history strategy as the opposite has been more commonly reported …”

BACKGROUND Resistance to pesticides is an evolutionary process that entails, in most cases, substantial consequences to the biology of the resistant populations. In this study we focus on the life history traits of the potato tuber moth Tecia solanivora, an invasive and voracious pest for which resistance to pyrethroid insecticides was recently reported. Marginally resistant and multiple‐resistant populations were selected from eight sampled localities in Colombia; the use of a fully susceptible population was not possible since none was recognized in the laboratory or field. The multiple‐resistant Siachoque population exhibited a 42‐fold resistance to the carbamate insecticide carbofuran, and low levels of resistance to chlorpyrifos, a trend observed in six of the eight tested populations. This population also exhibits 24‐fold resistance to permethrin. The marginally resistant population of Gualmatán showed 4‐fold resistance to chlorpyrifos. RESULTS The multiple‐resistant population exhibited a 3.8‐day shorter developmental time than the susceptible population, but with higher larval mortality. The peak of egg‐laying was delayed in the resistant population in 9 days and the population growth rate was lower than that of the susceptible population. CONCLUSION We hypothesize that the short developmental time of the multiple‐resistant population may be an adaptation to minimize exposure to insecticides, which are applied to the soil. This adaptation is likely to require the surviving adults to compensate for the smaller nutrient amounts accumulated by the larvae in investing part of its adult life in securing the necessary resources for late‐life egg production. © 2018 Society of Chemical Industry
