abstract = {Mites of the Brevipalpus genus are economically important due to their role as vectors of plant viruses. Among them, B. yothersi is well studied because it is the recognized main vector of the citrus leprosis virus C (CiLV-C), the causal agent of citrus leprosis, which is one of the most damaging viral diseases in the citrus crops. However, studies of several aspects of the biology of B. yothersi are still scarce, including its embryology. We performed a descriptive embryonic development study of B. yothersi, utilizing light and scanning electron microscope to obtain biological information of this particular phytovirus vector. Distinct events were recorded, such as centering of the nucleus, mitotic divisions for primitive body formation and appendages, as well as the presence of channels inside the egg and their possible association with the respiratory tract. Here we provide the first notes about embryonic development of this important mite vector in the Americas.},

abstract = {Xylella fastidiosa is a vector-borne bacterium that causes diseases in many plants of economic interest. The bacterium-vector initial interactions involve bacterial membrane-bound adhesins that mediate cell attachment to the foregut of insect vectors. We investigated the role of the afimbrial adhesin XadA2 in the binding and biofilm formation of X. fastidiosa subsp. pauca to vector surfaces in vitro, as well as its potential to disrupt pathogen transmission. We showed that XadA2 has binding affinity for polysaccharides on sharpshooter hindwings, used as a proxy for the interactions between X. fastidiosa and vectors. When in a medium without carbon sources, the bacterium used wing components, likely chitin, as a source of nutrients and formed a biofilm on the wing surface. There was a significant reduction in X. fastidiosa biofilm formation and cell aggregation on vector wings in competition assays with XadA2 or its specific antibody (anti-XadA2). Finally, pathogen acquisition and transmission to plant were significantly reduced when the vectors acquired X. fastidiosa from an artificial diet supplemented with anti-XadA2. These results show that XadA2 is important in mediating bacterial colonization in the insect and that it could be used as a target for blocking X. fastidiosa transmission.},
