Light intensity and wavelength influence development, reproduction and locomotor activity in the predatory flower bug Orius sauteri (Poppius) (Hemiptera: Anthocoridae)

摘要: Light wavelength and intensity are physical factors that can affect arthropod development reproduction. The present study examined the development, reproduction locomotor activity of predatory flower bug, Orius sauteri (Poppius) (Hemiptera: Anthocoridae), under five light intensities (1000, 2000, 3000, 4000 5000 lux) wavelengths [red (678.5 nm), green (620.0 nm), yellow (581.7 nm), blue (478. 1 nm) white (all wavelengths)] at constant temperature (25 °C) RH (70 %). duration nymphal was extended lower intensities, primarily due to effects on first three instars. Under white, light, O. completed in 18.0 days, but by 3.2 days red it 7.4 days. Although preoviposition period reduced fecundity, they improved egg fertility. Both negatively affected period, fecundity Whereas adult female mean walking speed over a min longer (yellow red) increased it, ostensibly reflecting an avoidance response. respiration quotient females also elevated conditions. These findings informative for optimizing mass-rearing procedures maximizing its efficacy as biological control agent greenhouse cultures.
