A biological control model to manage the vector and the infection of Xylella fastidiosa on olive trees
Xylella fastidiosa pauca ST53 is the bacterium responsible for the Olive Quick Decline Syndrome that has killed millions of olive trees in Southern Italy. A recent work demonstrates that a ration...
A delivery system for field application of paratransgenic control
As an alternative to chemical pesticides, paratransgenesis relies on transformation of symbiotic bacteria of an arthropod vector to deliver molecules that disrupt pathogen transmission. For over a ...
A Guild-Based Protocol to Target Potential Natural Enemies of Philaenus spumarius (Hemiptera: Aphrophoridae), a Vector of Xylella fastidiosa (Xanthomonadaceae): A Case Study with Spiders in the Olive Grove
The olive grove is a key landscape across the Mediterranean basin. This agroecosystem is threatened by Xylella fastidiosa, the causal agent of the olive tree quick decline syndrome, Philaenus spu...
A paratransgenic strategy to block transmission of Xylella fastidiosa from the glassy-winged sharpshooter Homalodisca vitripennis
Arthropod-borne diseases remain a leading cause of human morbidity and mortality and exact an enormous toll on global agriculture. The practice of insecticide-based control is fraught with issues o...
Biocontrol of Pierce's disease of grapevine and citrus greening with a benign strain of Xylella fastidiosa
Vascular diseases caused by xylem-limited Xylella fastidiosa subspp. and phloem-limited Candidatus Liberibacter spp. result in large economic losses in many agricultural plants. X. fastidiosa is ra...
Biology and Prevalence in Northern Italy of Verrallia aucta (Diptera, Pipunculidae), a Parasitoid of Philaenus spumarius (Hemiptera, Aphrophoridae), the Main Vector of Xylella fastidiosa in Europe
The meadow spittlebug, Philaenus spumarius (L.) (Hemiptera Aphrophoridae), the main vector of Xylella fastidiosa Wells et al. in Europe, has few known natural enemies. The endoparasitoid Verralli...
Biology of Zagella delicata (Hymenoptera : Trichogrammatidae), an egg parasitoid of the sharpshooter Tapajosa rubromarginata (Hemiptera : Clypeorrhyncha : Clcadellidae) in Argentina
Research on biological control of glassy-winged sharpshooter (GWSS) Homalodisca coagulata (Say) started in the 1990s. This sharpshooter, vector of Pierce's disease bacteria Xylella fastidiosa Wells...
Causes and consequences of plant-associated biofilms
The rhizosphere is the critical interface between plant roots and soil where beneficial and harmful interactions between plants and microorganisms occur. Although microorganisms have historically b...
Diversity of endophytic bacterial populations and their interaction with Xylella fastidiosa in citrus plants
Citrus variegated chlorosis (CVC) is caused by Xylella fastidiosa, a phytopathogenic bacterium that can infect all Citrus sinensis cultivars. The endophytic bacterial communities of healthy, resist...
Egg Morphology and Stages of Embryonic Development of the Glassy-Winged Sharpshooter (Hemiptera: Cicadellidae)
The structure of the. egg and embryonic developmental stages of glassy-winged sharpshooter, Homalodisca vitripennis (Germar) (Hemiptera; Cicadellidae), an important vector of Xylella fastidiosa are...
Endosphere microbiome comparison between symptomatic and asymptomatic roots of Brassica napus infected with Plasmodiophora brassicae
Clubroot caused by Plasmodiophora brassicae, is a severe disease of cruciferous crops that causes large hypertrophic galls in the roots. The plant microbiome is important for growth promotion and d...
