However, the function of UGT gene in contributing to pesticide resistance in T. urticae remained largely unknown. In this study, it was found that the laboratory selected abamectin-resistant (AbR) strain had developed over 20,000-fold resistance compared with the susceptible strain (SS).

One of the significant ways to recognize the efficacy of the phytoseiid predatory mites is the study of their foraging behavior. Mutual interference is a negative relationship between a predator's searching efficiency and its density. This study appraised the effect of the age-dependent mutual interference of N. californicus on larvae and nymphs of Tetranychus urticae Koch under laboratory conditions at 25 ± 1℃, 70 ± 5% RH and a photoperiod of 16 L: 8D h. To determine the per capita searching efficiency and interference coefficient, Nicholson's model and linear regression were used, respectively. The results showed that the total predation of N. californicus reared on T. urticae nymphs was significantly affected by predator density and age. In addition, per capita searching efficiency of the predator significantly declined with predator density, which is the result of mutual interference. Furthermore, the slope of the linear regression (m) between the logarithm of per capita searching efficiency and the logarithm of the predator density increased, ranging from - 0.465 in 5-day-old individuals to -0.1452 in 40-day-old individuals. The negative effects of mutual interference decreased along with growing age. Our findings showed that in different tested ages, the rate of interference among adults differed compared to immature individuals.
