Oligonychus is a genus of mites in the family Tetranychidae, the spider mites.Many members of this genus are familiar pests of plants. Rearing of the life stages of the mite was carried out following leaf flotation technique. The life cycle of this species, Oligonychus coffeae, Nienter was studied on tea leaves in Darjeeling under laboratory conditions at 20°C and 65% relative humidity. National Pingtung University of Science and Technology, Pingtung, China 4-8. It appears that C. buchanani is better host among the two hosts as because the life cycle (egg to adult) was completed in shorter time, recording high fecundity and longer longevity.

Está bastante distribuido por las zonas de cultivo de estas especies, aunque se desconoce un poco su distribución en África Occidental y hay regiones donde no se ha registrado. (1989) Observations were recorded on freshly laid eggs on tea leaves and continued until individuals reached adulthood. International Journal of Scientific Research 2, 566–567. Kothari’s Economic and Industrial Guide of India. (2012) The life cycle of Oligonychus coffeae was completed earlier when the temperature was higher, while at lower temperature this species required a longer period to complete its life cycle. J. Zool. The life cycle of this species, Oligonychus coffeae, Nienter was studied on tea leaves in Darjeeling under laboratory conditions at 20°C and 65% relative humidity. 25, (1979) Ent., Influence of host plants on morphological and biological changes in Oligonychus coffeae (Nienter) in tea. To determine the life cycle, fecundity, longevity, sexual proportion, life table, genetic variability of populations in different altitudinal levels and biological control of Oligonychus coffeae, laboratory studies were carried out in the Faculty of Agricultural Sciences of the Technical University of Ambato. Low developmental threshold and thermal constant for female to develop and to moult into adult were 12.57℃ and 143.82 degree-day,respectively, while those for male are 12.55℃ and 142.15 degree-day, respectively.

Positive effects of female densities to its oviposition periods were observed, while negative relation was found with its female fecundities.

The tea plant, Camellia sinensis (L.), has been cultivated since ancient time and is host to several pest species that can significant reduce productivity. 21, Life Stages Type; Leaves / abnormal colours Leaves / abnormal leaf fall ... Mite [Oligonychus coffeae, Brevipalpus californicus, Polyphagotarsonemus latus, Calacarus carinatus] outbreaks - timely identification for effective implementation of acaricidal control measures in [Sri Lankan] tea lands. Colonies were kept at 15, 20, 25 or 30degC and a relative humidity of 70 +/- 5% in controlled cabinets. Further studies on the nature of damage and biochemical changes in leaves caused by the mite P. harti would help to formulate strategies to regulate its population. Li CY. In field samples, P. harti populations were highly abundant during the summer months and completely absent in the winter with average density ranging between 0.61 and 6.11 individuals per, 茶葉 Oligonychus coffeae (Nietner) 於15﹑20﹑25及30℃，75?%RH ，13L:11D之定溫生長箱內，以台茶12號浮葉飼育之。其各發育期隨飼育 溫度之增高而減短。各發育期之死亡率以15℃時最高。雌及雄發育期之 臨界低溫分別為12.57及12.55℃，有效積溫分別為143.82及 142.15日-度 。於30℃下，雄壽命(10.56日)長於雌(7.97日)，但於15℃下反而較 長(28.73日<30.61日)。飼育溫度之高低與每雌一生平均產卵量(eggs/♀) 、內在增殖率(r)及終極增殖率(λ)之變化成正比，與平均世代時間(T)、 族群倍增時間(Dd)及最高繁殖值(Rx)成反比；而淨增殖率(Ro)以25℃下最 高。茶葉於25℃下雌密度及飼育葉面積對其產卵量影響顯著，飼育葉 面積較雌密度對其每日每雌平均產卵量之影響為大。雌密度之大小與, To assess the total effects of avermectin and for rational application, the effects of a sublethal concentration (the LC20 was chosen as a representative) of avermectin on the development and reproduction of the citrus red mite, Panonychus citri (McGregor), were evaluated at 26 ± 1°C, 70–75% relative humidity and a photoperiod of 14 : 10 h light : dark in the laboratory.
