“…Based on these data, Lin (2013) estimated that O. mangiferus could complete 26 generations per year on mangoes in Taiwan. However, this figure dropped to 14-20 in Egypt on the same host (Zaher et al, 1982;Abou-Awad et al, 2011)…”

“…Above these temperatures, 185.9 and 175.7 DD are required by females and males, respectively, to complete development (Lin, 2013). Thus, one generation can be completed on mango in 27.4–48.1 days at constant conditions of 31°C/65%RH and 15°C/75%RH, respectively (Abou‐Awad et al, 2011). Fu et al (2002) and Lin (2013) report shorter generation times at both higher and lower temperatures: 9.2 and 13.2 days at 32 and 33°C, and 29.1 and up to 47 days at 16°C and 17°C.…”

The EFSA Panel on Plant Health performed a pest categorisation of the mango red spider mite, Oligonychus mangiferus (Rahman and Sapra, 1940) (Acari: Prostigmata: Tetranychidae), for the territory of the EU. This species is not included in the EU Commission Implementing Regulation 2019/2072. The polyphagous mite feeds on more than 50 host plants including tropical fruits such as mangoes and avocados and temperate fruits such as pears, peaches, pomegranates and grapes. It occurs in Africa, Asia, Oceania and South America. O. mangiferus is multivoltine and can develop throughout the year as long as temperatures are above 12°C. The species produces dense webs on the above-ground parts of their host plants, where all stages of development (egg, larva, nymph and adult) can be found. This species is considered a pest of mango, grapevine, lychee and pomegranate, mostly in areas with hotter climates than those occurring in the EU. Potential entry pathways for O. mangiferus include plants for planting with foliage, fruit and cut flowers. Plants for planting of a few hosts (i.e. Pinus, Prunus, Pyrus, Rosa, Vitis and Arecaceae) are banned from entering into the EU from countries where O. mangiferus is known to occur and can be considered as closed entry pathways. However, other plants for planting, as well as the fruit and the cut flowers pathways remain open. There are no EU records of interception. Should O. mangiferus enter the EU, the ample availability of hosts and the climatic conditions in the EU would most probably allow this species to successfully establish and spread, at least in southern MSs, where economic impact in different fruit production (e.g. pomegranate, mango and grape) is anticipated. O. mangiferus satisfies the criteria that are within the remit of EFSA to assess for this species to be regarded as a potential Union quarantine pest.

The mango red spider mite, Oligonychus mangiferus (Rhaman and Sapra), is a major mango pest in Taiwan. This mite damages the leaves of the mango tree and affects the quality of the fruit. This study investigates the life history of the mango red spider mite on Mangifera indica L. cv. Irwin at five constant temperatures (17, 21, 25, 29, and 33 °C), under 80 ± 5 % RH and L12:D12 photoperiod conditions. An increase in temperature significantly decreased the developmental times for each stage and the overall immature period in females and males. The lower developmental thresholds of the immature stage were 12.5 and 12.4 °C for females and males, respectively. The thermal summations for the development of the immature stage were 185.9 and 175.7 degree-days for females and males, respectively. Based on the annual field temperature, an estimated 26 generations can reproduce in a mango orchard annually. The longevity of adults of both sexes decreased as temperature increased, and adult males lived longer than females. The preoviposition periods were shorter than 1 day when the temperature exceeded 25 °C. The development period and the oviposition period were shortest at 29 °C. At this point, daily fecundity was highest, and fecundity was second highest, resulting in the highest intrinsic rate of increase (r m ), 0.182 day(-1). These life history traits are applied to improve the management of O. mangiferus.
