Data from: Tetranychus evansi spider mite populations suppress tomato defences to varying degrees
<p>Plant defence suppression is an offensive strategy of herbivores, in which they manipulate plant physiological processes to increase their performance. Paradoxically, defence suppression does not always benefit the defence-suppressing herbivores, because lowered plant defences can also enhance the performance of competing herbivores and can expose herbivores to increased predation. Suppression of plant defence may therefore entail considerable ecological costs depending on the presence of competitors and natural enemies in a community. Hence, we hypothesize that the optimal magnitude of suppression differs among locations. To investigate this, we studied defence suppression across populations of Tetranychus evansi spider mites, a herbivore from South America that is an invasive pest of solanaceous plants including cultivated tomato, Solanum lycopersicum, in other parts of the world. We measured the level of expression of defence marker genes in tomato plants after infestation with mites from eleven different T. evansi populations. These populations were chosen across a range of native (South American) and non-native (other continents) environments and from different host plant species. We found significant variation at three out of four defence marker genes, demonstrating that T. evansi populations suppress jasmonic acid- and salicylic acid-dependent plant signalling pathways to varying degrees. While we found no indication that this variation in defence suppression was explained by differences in host plant species, invasive populations tended to suppress plant defence to a smaller extent than native populations. This may reflect either the genetic lineage of T. evansi - as all invasive populations we studied belong to one linage and both native populations to another - or the absence of specialized natural enemies in invasive T. evansi populations.</p>

The effects of water-stress, temperature, and plant traits on the outbreak potential of a specialist and generalist spider mite species (Acari: Tetranychidae)
<p>The host-generalist two-spotted spider mite [<em>Tetranychus</em> <em>urticae</em> (Acari: Tetranychidae); TSM] and host-specialist Banks grass mite [<em>Oligonychus</em> <em>pratensis</em> (Acari: Tetranychidae); BGM] are common pests of corn (<em>Zea</em> <em>mays</em> L.) in the arid western United States. Climate warming and decreased precipitation may promote conditions favored by these spider mites. However, rapid evolution of spider mite resistance to commercially available acaricides is driving the need for alternative solutions for managing outbreaks. Planting of drought-tolerant corn hybrids has been proposed to be a dual-purpose strategy for mitigating water deficits for irrigation and reducing leaf conditions favorable for BGM outbreaks. However, understanding of the mechanisms responsible for reducing the BGM in the field is lacking, and determining whether outbreaks of the TSM can also be averted using drought-tolerant corn is a pressing concern. We conducted a two-year field study testing a drought-tolerant corn hybrid and an analogous drought-susceptible hybrid under water-stress with artificially-infested spider mite populations. Drought-tolerant corn had larger stem diameter, more massive cobs, and greater leaf water mass compared to the drought-susceptible corn under water stress. We also found that the BGM populations were reduced on drought-tolerant plants under water-stress, as expected, but we found an opposite trend in the TSM. Lastly, water-stressed leaves were warmer, transpired less, and had higher carbon concentration, which contributed to larger investment in eggs and growth in the BGM. We anticipate that further evaluation of irrigation and crop drought-tolerance in management of agriculture systems for multiple pest species will be increasingly impactful in arid regions.</p>
