Spider mites (Tetranychidae sp.) are widely occurring arthropod pests on cultivated plants. Feeding by the two-spotted spider mite T. urticae, a generalist herbivore, induces defense response in plants that mainly depends phytohormones jasmonic acid and salicylic (SA). On tomato (Solanum lycopersicum), however, certain genotypes of urticae specialist species evansi were found to suppress these defenses. This phenomenon occurs downstream phytohormone accumulation via an unknown mechanism. We...
The two-spotted spider mite Tetranychus urticae is an extremely polyphagous crop pest. Alongside unparalleled detoxification potential for plant secondary metabolites, it has recently been shown that mites can attenuate or even suppress defenses. Salivary constituents, notably effectors, have proposed to play important role in manipulating defenses and might determine the outcome of plant-mite interactions. Here, proteomic composition saliva from T. lines adapted various host plants-bean,...
The use of CRISPR-Cas9 has revolutionized functional genetic work in many organisms, including more and insect species. However, successful gene editing or transformation not yet been reported for chelicerates, the second largest group terrestrial animals. Within this group, some mite tick species are economically very important agriculture human health, availability a gene-editing tool would be significant advancement field. Here, we report on spider Tetranychus urticae. ovary virgin adult...
Although many phenylpropanoid pathway-derived molecules act as physical and chemical barriers to pests pathogens, comparatively little is known about their role in regulating plant immunity. To explore this research field, we transiently perturbed the pathway through application of CINNAMIC ACID-4-HYDROXYLASE (C4H) inhibitor piperonylic acid (PA). Using bioassays involving diverse show that transient C4H inhibition triggers systemic, broad-spectrum resistance higher plants without affecting...
Mitochondrial Electron Transport Inhibitors of complex I (METI-I), such as tebufenpyrad and fenpyroximate, are acaricides that have been used extensively to control Tetranychus urticae Koch (Acari: Tetranychidae) for more than 20 years. Because the ability this spider mite rapidly develop acaricide resistance, field (cross-) resistance monitoring elucidation mechanisms extremely important management (RM). In present study, 42 European T. populations were screened fenpyroximate correlation...
The salivary protein repertoire released by the herbivorous pest Tetranychus urticae is assumed to hold keys its success on diverse crops. We report a spider mite-specific family that expanded in T. urticae. encoding genes have an expression pattern restricted anterior podocephalic glands, while peptide fragments were found secretome, supporting nature of these proteins. As identified host-dependent manner, we designated this as SHOT (secreted host-responsive Tetranychidae) family. proteins...
Development, survival and reproduction of Proprioseiopsis lenis (Corpuz Rimando) (Acari: Phytoseiidae), a predatory mite distributed in parts Southeast Asia, were assessed on different foods. These included four pollens (Typha latifolia, Luffa aegyptiaca, Zea mays, Ricinus communis), the natural prey Tetranychus urticae (mixed stages) Frankliniella occidentalis (first-second instars), storage Carpoglyphus lactis as factitious prey. The total immature developmental time females fed at 27 °C...

The two spotted spider mite Tetranychus urticae is a polyphagous pest with an extraordinary ability to develop acaricide resistance. Here, we characterize the resistance mechanisms in T. population (VR-BE) collected from Belgian tomato greenhouse, where grower was unsuccessful chemically controlling resulting crop loss. Upon arrival laboratory, VR-BE established both on bean and plants as hosts. Toxicity bioassays populations confirmed that highly multi-resistant, recording 12 out of 13...
