Abstract
AbstractA combination of natural enemies such as phytoseiid predators with compatible acaricides could decrease not only chemical applications but also the environment hazard, which is an objective of IPM programs. For this purpose, in this study, the effect of sub-lethal concentrations of pyridaben at 5, 10, and 15% lethal concentrations on development and reproduction parameters of Neoseiulus californicus (McGregor) (Acari: Phytoseiidae) was investigated. Lethal and sub-lethal concentrations were estimated using leaf dip bioassay method. LC5, LC10, LC15, and LC50 were 41.207, 58.676, 74.476, and 204.123 ppm, respectively. The oviposition period and fecundity decreased significantly with increase in concentration. The values of intrinsic rate of increase (r), finite rate of increase (λ), gross reproductive rate (GRR), and net reproductive rate (R0) tended to be lower in the LC5, LC10, and LC15 treatment groups than in the control. Therefore, it is possible that pyridaben caused sub-lethal effects on N. c...
