“…The adult oviposition period decreased as the wavelength increased as shown with findings from other studies on predatory insects (Pakyari & Reddy 2022;Wang et al 2014). Nevertheless, light wavelength did not significantly affect the preoviposition period of females in our research.…”

“…The wavelength of light, intensities of light and photoperiod can influence the reproduction, development and predation rate of arthropoda (Pakyari & McNeill 2020;Pan et al 2021). Predators and parasitoids have received significant interest in this context due to the necessity of understanding the impact of light on biological control outcomes (Pakyari & Reddy 2022;Pan et al 2021). For example, wavelength influence developmental and reproduction parameters in the predatory thrips, Scolothrips longicornis Priesner (Thysanoptera: Thripidae) (Pakyari & Reddy 2022).…”

“…The aim of this study was to evaluate the impact of visible light wavelength on the developmental rate, reproduction and survival of P. persimilis and its population parametres like the net reproductive rate (R 0 ), the intrinsic rate of growth (r), the finite rate of growth (λ), and the average generation time (T) (Carey 2001) estimated by life tables analysis (Jones 2021). We used the agestage, two-sex life table approach (Chi 1988) which has been prefered method applied in recent studies on predators and parasitoids (Chi & Yang 2003;Yang et al 2021;Cao et al 2023;Pakyari & Reddy 2022;Pakyari & Atlihan 2023).…”

Environmental factors, such as the wavelength of light, can have a crucial impact on mite development. Little is, however, known about the effect of visible light quality on demographic parameters of Phytoseiidae. We therefore conducted series of laboratory experiments in which development and reproduction of Phytoseiulus persimilis Athias-Henriot feeding on Tetranychus urticae Koch eggs was investigated under various light conditions (white, blue, green, yellow, and red light). The results revealed that different light wavelengths influenced each developmental stage, with the green light conditions promoting longest pre-adult development. The longevity of both male and female mites varied significantly across light wavelengths, with the shortest lifespan observed under red light. The highest mean total fecundity, 16 eggs per female, was observed under white light conditions. Population parameters (R0, r, and λ) were also highest under white light and decreased with increasing light wavelength. These findings suggest that light wavelength plays a significant role in development, survival, and reproduction of the predatory mite, with white light being identified as providing the best light conditions for commercial production of P. persimilis.
