FUNGI PATHOGENICITY TEST IN ‘HASS’ AVOCADO PLANTS RELATED TO AMBROSIAL COMPLEXES

Tropical and Subtropical Agroecosystems, 2022
Background: recently there has been concern for the monitoring of ambrosial complexes in Mexico that consist of a symbiotic relationship between a beetle and fungi, where the female invades a wide variety of species making galleries in the bark and wood,

Pest categorisation of non-EU Scolytinae on non-coniferous hosts. [PDF]

EFSA J
Abstract The EFSA Panel on Plant Health performed a group pest categorisation for the EU territory of non‐EU Scolytinae (Coleoptera: Curculionidae) on non‐coniferous hosts, which total 6495 known species. Most species attack apparently healthy, weakened or dead trees, either feeding on the phloem (‘bark beetles’ subgroup) or on fungi inoculated into ...

Stem Water Content for Crape Myrtle in Response to Drought, Cold, and Disease Stress

Journal of Sensors, Volume 2020, Issue 1, 2020., 2020
The abiotic and biotic stresses including drought, cold, and disease stress are linked by the fact that they all decrease the availability of water to plant cells. In previous studies, some physiological factors related with plant water status, such as stem sap flow, leaf transpiration rate, and water potential, were used to assess the effects of these

Pest categorisation of non‐EU Scolytinae of coniferous hosts

EFSA Journal, Volume 18, Issue 1, January 2020., 2020
Abstract The Panel on Plant Health performed a pest categorisation of non‐EU Scolytinae (Coleoptera: Curculionidae) of coniferous hosts (hereafter NESC). NESC occur worldwide, and some species are important forest pests. Species can be identified using taxonomic keys and molecular methods.

North American Lauraceae: terpenoid emissions, relative attraction and boring preferences of redbay ambrosia beetle, Xyleborus glabratus (coleoptera: curculionidae: scolytinae). [PDF]

PLoS ONE, 2014
The invasive redbay ambrosia beetle, Xyleborus glabratus, is the primary vector of Raffaelea lauricola, a symbiotic fungus and the etiologic agent of laurel wilt. This lethal disease has caused severe mortality of redbay (Persea borbonia) and swampbay (P.

California Laurel Is Susceptible to Laurel Wilt Caused by Raffaelea lauricola [PDF]

Plant Disease, 2008
Extensive mortality of redbay (Persea borbonia (L.) Spreng.) has been observed in the southeastern United States since 2003. The mortality is due to laurel wilt caused by Raffaelea lauricola T. C. Harr., Fraedrich & Aghayeva, a fungal symbiont of the recently introduced redbay ambrosia beetle (RAB), Xyleborus glabratus Eichhoff (1,2).

First Report of Laurel Wilt Caused by Raffaelea lauricola on Sassafras in Mississippi

Plant Disease, 2011
Laurel wilt is caused by the fungus Raffaelea lauricola T.C. Harrin., Aghayeva & Fraedrich and is lethal to redbay (Persea borbonia (L.) Spreng.), sassafras (Sassafras albidum (Nutt.) Nees), and other species in the Lauraceae (1). The fungus is carried by the redbay ambrosia beetle (Xyleborus glabratus Eichh.), which is native to Asia. After being

Variation in xylem characteristics of botanical races of Persea americana and their potential influence on susceptibility to the pathogen Raffaelea lauricola [PDF]

Tropical Plant Pathology, 2020
AbstractAvocado (Persea americana), an important fruit crop, is under threat from an invasive disease, laurel wilt. The pathogen,Raffaelea lauricola, spreads rapidly in the xylem of infected trees and causes a lethal vascular wilt. A previous study showed that variation in susceptibility to the disease exists among different races of avocado, with the ...
