Odorant Binding Proteins (OBPs, https://en.wikipedia.org/wiki/Odorant-binding_protein) are small soluble “bowl-like” proteins composed of 6 Cys, six-seven α-helices and a central hydrophobic pocket. This structure is largely described in insects and strongly believed to play a key role in the transport of hydrophobic chains such as odorant/pheromone molecules. Following their dis ...

Screening of EST-database from the whitefly B. tabaci allowed identification of three BtabCSP clones (BtabCSP-1, BtabCSP2 and BtabCSP3; Liu et al., 2016a,b). In the course of our studies on whitefly CSPs, we have shown that BtabCSPs and in particular BtabCSP2 contain specific genomic DNA sequences (Q260, BaA, CWF-1, BaA, OPT12 and SCAR markers) that can become extremely useful for biotyping. BtabC ...

In 2012, we set out to establish a new analytical chemistry platform for the analysis of soil, crop, plant, leaf and insect samples with focus given to insecticides, toxin residuals, phosphates, odors, nutrients, lipid precursors and pheromone signals underlying sex-specific reproductive behaviors. Meanwhile, we set out to organize a communication and exchange platform for cooperation between Chin ...

IntroductionWhiteflies are well known as severe agricultural pests, devastating all sorts of green ornamental and vegetable plants around the world. Whitefly species such as the sweet potato Bemisia tabaci Gennadius pierce and suck the sap, causing direct and indirect damages to various plant species. Bemisia damages the plants at all various moments of their life cycle. Females lay eggs on t ...

Animal breeding is an old practice developed by humans for the production of dairy foods (cattle), transport (horses), rodeo or recreational events (dogs and bison for instance). The task of domestication and/or specific animal breeding at the industrial level includes controlled mating, successful reproduction of captive species and mass production of selected strains for our own consumption or p ...
