“…The highest rm values of O. mangiferus in the present study and that of Ming-Ying Lin (2013) Fu and Zhang (2002) and Abou-Awad et al (2011) averaged 0.178, 0.182, 0.396 and 0.125, when the temperature was 31, 29, 28, 31 °C, respectively. On the other hand, Wrensch (1985) found that the highest rm values of various Tetranychus species ranged from 0.355 to 0.46.…”

“…Longevity period of spider mite decreases as increasing of temperature (Zaher and Shehata 1971;Fu and Zhang 2002;Abou-Awad et al 2011;Ming-Ying Lin 2013). The longevity of O. mangiferus recorded in this study resembles that of Zaher and Shehata (1971), Fu and Zhang (2002) and Ming-Ying Lin (2013) while Nangia et al (1989) and Abou-Awad et al (2011) found that O. mangiferus lived considerably longer. Table (3) showed that the net reproductive rate (R0) decreased when temperature increased.…”

Life history and reproductive parameters of the mango red spider mite, Oligonychus mangiferus (Rahman and Sapra) (Acari: Tetranychidae) were studied to investigate its response to different temperatures (25, 28 and 31 ºC), with 70 ± 5% R.H. on Mangifera indica L. Baladi variety in the laboratory. The results showed that the developmental time of the individuals shortened with increasing temperature. The total immature stages was the longest period (7.51 day for the female and 7.46 day for the male) at 25 ºC, while at 31°C was the shortest period (6.48 and 6.46 day, respectively). The life cycle was the longest period (12.18 day for the female and 11.71 day for the male) at 25 ºC, while at 31°C was the shortest period (10.78 and 10.38 day, respectively). So, the mean generation time was the longest (20.12 days) at 25 °C, followed by 28 °C (19.06 days) and then at 31°C was the shortest (17.87 days). On the contrary, total fecundity was 32.50 eggs (2.05 eggs/♀/day) at 25 ºC, then at 28 °C it reached 30.17 eggs (2.01 eggs/♀/day) and 26.83 eggs (1.93 eggs/♀/day) at 31°C, respectively. The mean generation time recorded the shortest (17.87 days) at 31°C, while the fecundity recorded the highest rate at 25 ºC (32.50 eggs; 2.05 eggs/♀/day). Based on these results, we can predict the presence of O. mangiferus on mango. Therefore, it should be easily to determine the best time to control this pest.

“…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 European Commission requested the EFSA Panel on Plant Health to prepare and deliver risk assessments for commodities listed in Commission Implementing Regulation (EU) 2018/2019 as ‘High risk plants, plant products and other objects’. This Scientific Opinion covers the plant health risks posed by the following commodities: i) dormant and free of leaves 1‐year‐old bare rooted plants and ii) free of leaves 1‐year‐old liners of Ficus carica imported from Israel, taking into account the available scientific information, including the technical information provided by Israel. The relevance of any pest for this opinion was based on evidence following defined criteria. Four EU quarantine pests, Euwallacea fornicatus, Hypothenemus leprieuri, Scirtothrips dorsalis and Spodoptera frugiperda, and 11 EU non‐regulated pests fulfilled all relevant criteria and were selected for further evaluation. For these pests, the risk mitigation measures proposed in the technical dossier from Israel were evaluated separately for bare rooted plants and for liners, taking into account the possible limiting factors. For these pests, an expert judgement was given on the likelihood of pest freedom taking into consideration the risk mitigation measures acting on the pest, including uncertainties associated with the assessment. The estimated degree of pest freedom varied among the pests evaluated. Aonidiella orientalis and Russellaspis pustulans were the most frequently expected pests on the imported bare rooted plants, and Scirtothrips dorsalis on liners. The Expert Knowledge Elicitation indicated, with 95% certainty, that between 9,585 and 10,000 bare rooted plants per 10,000 would be free of Aonidiella orientalis and Russellaspis pustulans and between 9,456 and 10,000 liners per 10,000 would be free of Scirtothrips dorsalis.
