Molecular interactions of plant viral satellites | SpringerLink

Plant viral satellites fall under the category of subviral agents. Their genomes are composed of small RNA or DNA molecules a few hundred nucleotides in length and contain an assortment of highly complex and overlapping functions. Each lacks the ability to either replicate or undergo encapsidation or both in the absence of a helper virus (HV). As the number of known satellites increases

2002). In many disease systems where the vector is a leafhopper, disease incidence declines with distance from the source of the vector (Purcell 1974). Proximity to host plants of the vector also increases disease incidence (McClure 1980; Grilli and Gorla 1998). Correlating temporal incidence of insect populations with disease

Vector Control - an overview | ScienceDirect Topics

Vector control. Vector control uses larvicides to kill the Simulium larvae. This has been most effectively carried out by the Onchocerciasis Control Project (OCP) in 11 countries of West Africa. Unfortunately, vector control is very expensive, as selective larvicides must be delivered to all breeding sites, including the most remote and

The results suggest that a derivative of a mini binary vector pCB302 is superior to pCAMBIA1305.1 for the construction of infectious and stable DNA clones of vitiviruses. Successful construction of such DNA clones of GVA and GVB reported in this study is a clear step towards fulfilling Koch’s 3rd postulate in investigating the aetiology of

The Genesis of Malaria | Answers in Genesis

6/19/2013 · Mosquitoes, the vector of Plasmodium, were probably designed to be pollinators, not parasite vectors. In this article, we present both the evolutionary and creation explanation for the origin of malaria with a mention to its vector, the mosquito. The purpose of this article is to provide a reasonable explanation for the genesis of malaria.

Methods for the detection of plant virus diseases Methods for the detection of plant virus diseases of the virus with its host and/or vector (e.g., symptomatology and transmission tests) Symptoms on plants commonly are used to characterize a disease having viral aetiology and for roguing of diseased plants in an attempt to control the

A New Natural Planthopper Vector of Stolbur Phytoplasma in

A new disease of sugar beet called Syndrome des Basses Richesses, which appeared in Burgundy and Franche-Comté, France, in 1991, is of uncertain aetiology. However, evidence for aerial transmission of the disease, symptom similarity with yellow wilt and preliminary results of phytoplasma detection, support the hypothesis of a phytoplasma being associated to the disease. A search for a natural
