Bacterial Diversity and Distribution from the Whole Mite Extracts in Acaricide Resistant and Susceptible Populations of Twospotted Spider Mite-Tetranychus urticae (Acari: Tetranychidae)

Microorgans in herbivorous two-spotted spider mites regulate ecological interactions with lima bean plant

“…Bacteria have been found to occur in spider mites (Yoon et al 2010). We found two types of microbes existing in spider mites.…”

Bacterial communities in natural versus pesticide‐treated Aphis gossypii populations in North China

“…There were 22 biomarkers identified at the genus‐level, all of them raised the relative abundance in the phoxim‐treated population. There were some types that are probably involved in insect resistance to pesticides, such as Acinetobacter , which was isolated from the midgut of a pesticide‐resistant H. armigera (Malhotra et al., ), and Chryseobacterium isolated from the pyridaben‐resistant population of Tetranychus urticae (Yoon et al., ). Many pesticides can be degraded by Kocuria , Nocardioides or Pseudonocardia (Bostanian & Akalach, ; Chakraborty & Das, ; Kumar, Kumar, & Sharma, ).…”

Herbivore-Associated Bacteria as Potential Mediators and Modifiers of Induced Plant Defense Against Spider Mites and Thrips

“…In any case, members of both families may harbor bacteria that have been found to manipulate plant defense in other arthropods (Supplementary Tables S1 , S2 ). Among Tetranychidae, two-spotted spider mites T. urticae and T. evansi are especially well studied, with a large number and diversity of gut/saliva and endosymbiotic bacteria (e.g., Yoon et al, 2010 ; Knegt et al, 2017 ; Staudacher et al, 2017 for gut bacteria; e.g., Zélé et al, 2018 for endosymbionts). Spider mite species are especially likely to harbor single or multiple reproductive symbionts such as Wolbachia , Cardinium , or Spiroplasma (Supplementary Tables S1 , S2 ).…”

“…Additional or alternative explanations on the plant side include multiple signals masking each other or reflecting a conflict in the response of the plant to herbivore attack because of simultaneously perceiving endogenous spider mite signals (normally inducing the JA pathway) and bacteria-related signals (normally inducing the SA pathway), together resulting in no or suppressed plant response. Overall, it cannot be excluded that intraspecific variations in induction of plant responses observed in different spider mite species such as Tetranychus kanzawai ( Matsushima et al, 2006 ), T. evansi ( Sarmento et al, 2011 ), and T. urticae ( Kant et al, 2008 ), which correlate with genetic differences ( Yano et al, 2003 ; Villarroel et al, 2016 ), may be co-determined by differences in the bacteriome ( Yoon et al, 2010 ; Knegt et al, 2017 ; Zélé et al, 2018 ). Genetic intraspecific differences such as resistance to acaricides may covary with differences in the quantity and diversity of HAB ( Yoon et al, 2010 ).…”

In addition to reproductive endosymbionts, Yoon et al (2010) detected also Pantoea , Enterobacter , and Pseudomonas in the gut of T. urticae ; in the absence of reproductive endosymbionts, Knegt et al (2017) detected Pseudomonas and Stenotrophomonas in the gut of T. evansi .…”
