O. coffeae is an important pest of tea and coffee in India. O. coffeae on mango was first detected in Okinawa Island in 1996. The occurrence of O. coffeae on mango was reported to b abundant from spring to autumn in which climates are relatively hot. Seasonal abundance of O. coffeae may be affected by the developmental and ovipositional pattern in each season. Thus I investigated the effect of temperature on development and oviposition in O. coffeae. The mites used in this experiment were collected from a green house of mango in Okinawa Island. Eggs were placed in incubators controlled for 20℃, 25℃ and 30℃. Developmental period (from egg to adult emergence), the number of eggs oviposited and longevity of females were recorded, using a binocular. Developmental period was delayed at low temperature, whereas it accelerated at high temperature. There was no significant difference in longevity among females in each temperature. Total egg number per life was significantly larger at 25℃ than at 20℃. The number at 30℃ was intermidiated among 20℃ and 25℃. Eggs were oviposited more in earlier stage of female than later one at 25℃ and 30℃. Based on these results, population dynamics in O. coffeae were discussed., 論文}, pages = {47--49}, title = {マンゴーハダニ Oligonychus coffeae (Nietner) の発育と産卵に及ぼす温度の影響}, volume = {34}, year = {1999} }
