Effects of temperature on diapause induction in the codling moth, Cydia pomonella (L.) (Lepidoptera: Olethreutidae)
Environmental Entomology 17 (4), 626-628
Abstract: The effect of prediapause temperature on diapause induction was investigated in a Michigan strain of the codling moth, Cydia pomonella (L.). A temperature of 17°C enhanced diapause induction, but higher temperatures averted or diminished the photoperiodic response of the codling moth larva to diapause induction. The critical photoperiod (L:D) for 50% induction of diapause was 15 : 9, 14.4 : 9.6, 13.8 : 10.2, and 13.44 : 10.56 at 17, 22, 27, and 30°C, respectively. A method of estimating the diapause response of the codling moth to temperature is presented.
