The lower thermal threshold and the thermal constant for egg-to-egg development of the shiso rust mite, Shevtchenkella sp., causing damage to Perilla frutescens (Laminaceae) were 12.8°C and 133.5 degree-days, respectively. Zero fecundity was estimated at 13.1°C, based on regression analysis carried out on the average number of eggs per female per day. The critical photoperiod of the mite reared in the laboratory was between 13 and 14 hours of light at 21°C, and 50% diapause females were predicted to appear in early October in the field in Tokyo. This was tested and proved correct: half of the females collected from the field in the beginning of October were in diapause condition. Nymphs and adults were trapped on glass slides coated with high vacuum silicon grease, outside two greenhouses in Kochi Prefecture throughout the year, indicating that the mite disperses through the air. Both, the eggs and adults of the mites died within 24 hours at 40°C, whereas both stages could survive up to 96 hours at 5°C.
