| Abstract: | Summary
Pieris brassicae larvae were reared under 9 h/24 h white light and 20°C (conditions determining the diapause status). From the pupal moult they were exposed for 20 days under different wavelengths (absorbed or not by the green integumentary pigment: pterobilin). This treatment has no effect on diapause. |
