“…Choice of insecticide is critical and must take into account treatments for other pests, such as lice. In the past, insecticide residues left by organochlorine lice treatments contributed to dieldrin resistance in blowflies (McKenzie & Whitten 1984). Similarly, benzoylphenyl-urea lice treatments (diflubenzuron and triflumuron) may have played a role in the development of diflubenzuron resistance in L. cuprina .…”

Resistance to diflubenzuron in the Australian sheep blowfly, Lucilia cuprina , has rendered this insecticide incapable of preventing flystrike in sheep from a few districts in eastern Australia. Wool producers affected by this situation must find suitable alternatives to protect their flocks. Results of laboratory bioassays against one population demonstrated that, despite extremely high diflubenzuron resistance (Resistance Factor > 791), it had only very low (2x) tolerance of cyromazine and dicyclanil. It is unlikely that this level of tolerance would have any practical impact on field control with either insecticide. Consequently, wool producers in districts where diflubenzuron-resistant flies are common can rotate insecticide treatment to either of these compounds to prevent flystrike in their flocks. However, unlike the highly diflubenzuron-resistant field strain, a laboratory strain selected for resistance to diflubenzuron (Resistance Factor = 617) was 10 times more resistant to dicyclanil than a susceptible strain but, like the field strain, was only two times more tolerant of cyromazine. Conversely, a field-derived strain selected in the laboratory for cyromazine resistance was 20 times more resistant to dicyclanil and 362 times more resistant to diflubenzuron than the reference susceptible strain.

“…The work of Curtis et al (1978) on Anopheles spp. and that of McKenzie & Whitten (1982, 1984 on Lucilia cuprina (Wiedemann) are two rare instances where such data are presented. In the present paper, I have attempted to provide fitness estimates for malathion-resistant and susceptible genotypes of O. surinamensis and to assess the results in the light of models currently available for delaying the evolution of insecticide resistance.…”

A malathion-resistant strain of Oryzaephilus surinamensis (L.) was subjected to selection with malathion for ten generations at three doses, 65, 260 and 390 mg/m 2 . The relative fitness of the resistant homozygote, the heterozygote and the susceptible homozygote were estimated at each dose and in an untreated control population by comparing the change in frequency of the susceptible homozygote from generation to generation. In the absence of the insecticide, the resistant genotypes had a fitness coefficient of 0-82 compared to the susceptibles, whereas following selection at the highest dose of malathion, the fitness coefficient of the susceptible homozygote was 0 and that of the heterozygote 0-4, compared to the resistant homozygote. With selection at the highest dose of malathion, the frequency of the resistance gene rose from 0-5 to around 1-0 during the experiment, and this was accompanied by a 2-3-fold increase in the resistance factor at the ED50. A model is provided to show how the data collected in these experiments can be used to predict the increase in resistance under various treatment regimes. The model shows that although resistance would be delayed longest at the lowest dose, such a dose would fail to control the pest population. Using the data from these experiments, the model predicts that the best combination of control and delay of the spread of resistance would be achieved by using the highest dose of malathion while allowing the maximum acceptable proportion of beetles to remain untreated.

“…One of the major and more difficult problems in population and evolutionary genetics is to elucidate the complex genetic basis of adaptive characteristics of animal populations (Tauber ~nd Tauber 1978;Curtsinger and Laurie-Ahlberg 1982;Parsons 1982). The choice of characters which can be reasonably related to fitness, such as heavy metal tolerance in plants (Antonovics and Bradshaw 1970) and insecticide resistance in blowflies (McKenzie and Whitten 1984), will potentially reveal much about how new environments lead to changes in the genetic constitution of populations. One experimental system with considerable promise towards this end is tolerance to environmental alcohol by Drosophila melanogaster.…”

Variation in alcohol dehyqrogenase (ADH) and alcohol tolerance was investigated in AdhF isofemale lines of D. melanogaster isolated from an Australian winery population. For three different tests of alcohol tolerance no association with levels of ADH activity was detected. However, among 156 lines a significant negative asso9iation occurred between larval ethanol tolerance and the quantity of ADH enzyme measured in adults. In addition, a positive relationship occurred between ADH quantity and adult survival in a sucrose-ethanol ingestion test carried out on 28 of the lines. No correlation of enzyme quantity occurred when aqults were acutely exposed to ethanol vapour. These data indicate that ADH quantity and not ADH activity may be a mor.e crucial physiological determinant of survival in high ethanol environments.
