説明
Critical photoperiod and geographical variation of diapause induction in the two-spotted spider mite collected from various districts of Japan were analysed with reference to susceptibility to malathion.<br>Under various light regimes, the diapause rate of the Sapporo population increased with decrease in temperature, although under the 13.5L-10.5D regime, no diapause was observed even at 15°C. Critical photoperiods at 15°C for the various populations were 12hr 50min for the Sapporo and Morioka, 12hr for the Fukushima and 9hr 40min for the Ichikawa population. The Fukuoka and Kagoshima populations did not diapause under the experimental conditions. When the mites from Sapporo, Fukushima and Ichikawa were reared on the field in Matsudo District, the diapausing females appeared from eggs laid at the beginning of October when the observation was started. However, in the Kagoshima population, no diapausing females appeared even as late as at the beginning of November. LC50 values obtained from the experiment on the mite populations susceptible to malathion were 44, 250, 148, 218, 683 and 161ppm for the Sapporo, Morioka, Fukushima, Ichikawa, Fukuoka and Kagoshima populations, respectively. No distinct relationship was noted between the diapause and the susceptibility to organophosphorus insecticide.
