“…E. sexmaculatus can be a serious pest of avocados in New Zealand and in California, especially in foggy coastal areas (Jamieson and Stevens, 2007;UC IPM, 2016), citrus (Li et al, 1997;Vacante, 2010), plumeria (Yang andLin, 1983) and rubber trees in South-East Asia (Liang et al, 2020). According to Vacante (2010), E. sexmaculatus is a major pest of citrus in China, Hawaii, Korea, India, Iraq, Japan, Korea, New Zealand, Taiwan and the USA.…”

The EFSA Panel on Plant Health performed a pest categorisation of Eotetranychus sexmaculatus (Acari: Tetranychidae), the six-spotted spider mite, for the EU. The mite is native to North America and has spread to Asia and Oceania. It is not known to occur in the EU. The species is not listed in Annex II of Commission Implementing Regulation (EU) 2019/2072. E. sexmaculatus feeds on more than 50 hosts in 20 botanical families and can be a serious pest of important crops in the EU such as citrus (Citrus spp.), avocado (Persea americana), grapevine (Vitis spp.) and ornamentals such as Ficus spp. and Rosa spp. In California and New Zealand, the mite can breed continuously on evergreen hosts such as avocados and citrus, growing slowly during the winter and faster during the summer. Dry weather conditions hamper its development. Plants for planting, fruit, cut branches and cut flowers provide potential pathways for entry into the EU. Some host plants for planting are prohibited from entering the EU while others require a phytosanitary certificate, as do cut branches and cut flowers. In the warmer parts of southern EU Member States, climatic conditions and host plant availability are conducive for establishment and spread. The introduction of E. sexmaculatus is expected to have an economic impact in the EU through the reduction in yield, quality and commercial value of citrus and avocado production. Additional damage on other host plants, including ornamentals, under EU environmental conditions and cropping practices cannot be ruled out. Phytosanitary measures are available to reduce the likelihood of entry and spread. E. sexmaculatus satisfies with no key uncertainties the criteria that are within the remit of EFSA to assess for it to be regarded as a potential Union quarantine pest.

The spider mites Eotetranychus sexmaculatus, Eutetranychus orientalis and Oligonychus biharensisin are severe pests of rubber trees in China. The predatory mite Neoseiulus barkeri has been found to be a natural enemy of these three pests, while nothing is known about the biological performance of this phytoseiid predator against these phytophagous mites. In this study, the development, survivorship, reproduction, adult longevity, fecundity, sex ratio and population growth parameters of N. barkeri fed on these pests were evaluated in comparison to the factitious prey Tyrophagus putrescentiae in the laboratory at 25 ± 1 °C, 75 ± 5% relative humidity and a 12:12 (L:D) h photoperiod. The results showed that N. barkeri could develop from egg to adult and reproduced successfully on the three preys. The survival rate of N. barkeri from egg to adult was higher when fed on E. orientalis (100%) and T. putrescentiae (100%) than when fed on O. biharensisin (93.60%) and E. sexmaculatus (71.42%). The shortest and longest generation time for N. barkeri were observed on E. orientalis with 6.67 d and E. sexmaculatus with 12.50 d, respectively. The maximum fecundity (29.35 eggs per female) and highest intrinsic rate of increase (rm = 0.226) were recorded when N. barkeri fed on E. orientalis, while feeding on E. sexmaculatus gave the minimum fecundity (1.87 eggs per female) and lowest reproduction rate (rm = 0.041). The values of these parameters for N. barkeri evaluated on O. biharensisin were found to be comparable to those obtained on T. putrescentiae. The sex ratio of N. barkeri progeny on the preys mentioned above, apart from O. biharensisin, was female biased. According to the findings, N. barkeri could serve as a promising biocontrol agent against E. orientalis and O. biharensisin, and possibly E. sexmaculatus on rubber trees.
