Interaction between plants and their environment is changing as a consequence of the climate change and global warming, increasing the performance and dispersal of some pest species which become invasive species. Tetranychus evansi also known as the tomato red spider mite, is an invasive species which has been reported to increase its performance when feeding in the tomato cultivar Moneymaker (MM) under water deficit conditions. In order to clarify the underlying molecular events involved, we examined early plant molecular changes occurring on MM during T. evansi infestation alone or in combination with moderate drought stress. Hormonal profiling of MM plants showed an increase in abscisic acid (ABA) levels in drought-stressed plants while salicylic acid (SA) levels were higher in drought-stressed plants infested with T. evansi, indicating that SA is involved in the regulation of plant responses to this stress combination. Changes in the expression of ABA-dependent DREB2, NCED1, and RAB18 genes confirmed the presence of drought-dependent molecular responses in tomato plants and indicated that these responses could be modulated by the tomato red spider mite. Tomato metabolic profiling identified 42 differentially altered compounds produced by T. evansi attack, moderate drought stress, and/or their combination, reinforcing the idea of putative manipulation of tomato plant responses by tomato red spider mite. Altogether, these results indicate that the tomato red spider mite acts modulating plant responses to moderate drought stress by interfering with the ABA and SA hormonal responses, providing new insights into the early events occurring on plant biotic and abiotic stress interaction.

Surveys for predators of the tomato red spider mite Tetranychus evansi Baker & Pritchard on solanaceous plants were carried out in north-eastern and south-eastern Brazil to determine prospective species for the control of the pest in Africa. Surveys were carried out in areas identified as climatically similar to regions in Africa where T. evansi has been reported as a pest and where prospective natural enemies may be introduced. A total of 56,445 mites and insects were found in 330 samples collected from 20 different species of solanaceous plants. Tetranychus evansi was found in only three samples, on Solanum americanum Mill. and Lycopersicon esculentum Mill.. A total of 5,023 specimens of predatory mites, of at least 44 species, and 494 specimens of acarophagous insects, of at least three species were collected. The predominant predatory mites were (in decreasing order): Phytoseius guianensis DeLeon, Pronematus ubiquitus (McGregor), Asca sp., Paraphytoseius orientalis (Narayanan, Kaur & Ghai), Phytoseius woodburyii DeLeon, Amblyseius compositus Denmark & Muma, Homeopronematus anconai (Baker), Neoparaphytoseius sooretamus (El-Banhawy), Cunaxoides sp., Typhlodromus paraevectus Moraes & McMurtry, Typhlodromalus peregrinus (Muma) and Phytoseius cismontanus DeLeon. However, no predatory mites were found in association with T. evansi. Among the insects, although not the most abundant, Stethorus tridens Gordon seemed to be most promising, as it was found associated with T. evansi in all samples in which the latter was found. Feltiella sp. was the most abundant acarophagous insect found, but it was never found associated with the pest.

The tomato red spider mite, Tetranychus evansi, is an important invasive pest of solanaceous plants worldwide. China is a potentially suitable region for T. evansi but there was no official record of its distribution. In this study, we reported five new records of T. evansi from eggplant, tomato and cucumber in southern and southwest China. The invasion of T. evansi constitutes a new threat to solanaceous crops in mainland China.

The tea plant, Camellia sinensis (L.), has been cultivated since ancient time and is host to several pest species that can significant reduce productivity. One such pest species is the tea red spider mite. 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. Observations were recorded on freshly laid eggs on tea leaves and continued until individuals reached adulthood. The eggs required an average of 16.17 days to develop into adults. The average longevity of adult was 28.67 days. Our findings contribute to the understanding of mite abundance and population fluctuations in different seasons and climates, and will hopefully help to devise a management strategy for this pest species.
