Abstract:When populations of the twospotted spider mite, Tetranychus urticae Koch, were selected repeatedly in the laboratory with the pyrethroid flucythrinate, their behavioral responses to exposure to residues changed. Methods were developed to permit approximately equal segregation between treated and untreated primary leaves of French dwarf bean plants, Phaseolus vulgaris L., over a 24-h exposure period. Behavioral selections for increased or decreased irritability to flucythrinate residues continued for 11 selections. To maintain equal segregation, the concentration for selections for decreased irritability was incrementally increased from an initial value of 0.003 g (AI)/liter in selection 4 to reach 0.25 g (AI)/liter at selection 11. Selection for increased irritability was accomplished by decreasing concentrations from the initial 0.003 g (AI)/liter in selections 1 to 8, to 0.0008 g (AI)/liter by selection 11. Slide-dip tests at the recommended field rate (0.05 g [AI]/liter) showed no change in physiological resistance in either behavioral selections.
