Effect of induced resistance in bean plants on Tetranychus urticae life table parameters
In this study the effects of soil application of potassium phosphite, amino acid complex, and biolog siderophoric on the life table parameters of Tetranychus urticae have been investigated on bean plants, under laboratory conditions. The results revealed significant differences in the total developmental times, oviposition periods, and fecundity of T. urticae among the treatments. The shortest total developmental time and longevity was observed in biolog siderophoric treatment. The intrinsic rate of increase, the net reproductive rate, the finite rate of increase and the mean generation times of T. urticae were remarkably different among the treatments and lower than in the control. The lowest values of these parameters were observed in the biolog siderophoric treatment, which suggests that this inducer could be employed toward a sustainable management of T. urticae.
