“…In addition to direct damage, insect pests can also either directly transmit or facilitate secondary infections by viruses, bacteria and fungi. For example, the leafhopper, Scaphoideus titanus , transmits the grapevine yellows phytoplasma (Constable and Bertaccini, 2017), and the English grain aphid, Macrosiphum avenae , is a vector for barley yellow dwarf virus with infestations also leading to colonization by sooty moulds that establish on honeydew secretions (Fiebig et al ., 2004).…”

Summary Arthropod crop pests are responsible for 20% of global annual crop losses, a figure predicted to increase in a changing climate where the ranges of numerous species are projected to expand. At the same time, many insect species are beneficial, acting as pollinators and predators of pest species. For thousands of years, humans have used increasingly sophisticated chemical formulations to control insect pests but, as the scale of agriculture expanded to meet the needs of the global population, concerns about the negative impacts of agricultural practices on biodiversity have grown. While biological solutions, such as biological control agents and pheromones, have previously had relatively minor roles in pest management, biotechnology has opened the door to numerous new approaches for controlling insect pests. In this review, we look at how advances in synthetic biology and biotechnology are providing new options for pest control. We discuss emerging technologies for engineering resistant crops and insect populations and examine advances in biomanufacturing that are enabling the production of new products for pest control.

“…Phytoplasmas from several molecularly distinct taxonomic groups cause yellows diseases on grapevine (Constable and Bertaccini 2017). In Europe, 'Candidatus Phytoplasma solani' from the stolbur group 16 SrXII-A (Quaglino et al 2013), which causes bois noir (BN) disease, is the most widespread and may lead to up to 50% loss of grape clusters (Starý et al 2013).…”

Statistical modeling of long-term grapevine response to ‘Candidatus Phytoplasma solani’ infection in the field

Bois noir (BN) is the most widespread European grapevine yellows disease caused by 'Candidatus Phytoplasma solani'. Although our knowledge of the mechanisms of interactions of this pathogenic bacteria with host is largely unknown, the plant-pathogen system of BN is commonly used as a model system for studying grapevine yellows diseases. We applied here a conceptual model of general plant pathology -a disease triangle for describing interactions among the host plant, the pathogen and the environment. We generated a proofof-concept statistical model for disease triangle using original experimental data and different statistical and data mining approaches for a selected system of 'Ca. P. solani' infection of cv. 'Chardonnay' grapevine plants. We monitored individual plants from a single vineyard over a period of six years. Phytoplasma content, the expression of 21 selected grapevine genes and environmental conditions were recorded and related to disease severity. Our model predicts that in described conditions BN is a function of the expression of grapevine gene VvDMR6, summer rainfall and abundance of 'Ca. P. solani'. The greatest impact among elements of the disease triangle is attributed to the pathogen, and is independent of the pathogen titer. We showed that this first de facto representation of the disease triangle is useful for showing disease dynamics over several years and could be applied to other plant-pathogen systems. The overall results of this study will contribute to understanding of 'Ca. P. solani' biology and its interactions with grapevine host.

“…The disease of the grapevine caused by 'Candidatus Phytoplasma solani' -related strains (16SrXII-A) is called as "Bois noir" (Quaglino et al, 2013) and Bois noir was reported in many countries including some European countries and Turkey (Constable and Bertaccini, 2017;Ertunc et al, 2015). On the other hand, Aster yellows phytoplasmas (16SrI group) are one of the largest group and are of genetic diversity when compared to other phytoplasma groups (Lee et al 2004).…”

“…Among the plant species suitable host for phytoplasmas, the grapevine is considered to be one of the major fruit crops worldwide based on cultivated area and economic value worldwide (Pierro et al, 2019). Diseases caused by phytoplasmas generally described as "Grapevine yellows (GY)" have been reported in many viticultural areas worldwide, including the Americas, Africa, Australia, Asia and Europe (Constable and Bertaccini, 2017).…”
