Abstract

Studies on biological control ontrol of the white spotted longicorn beetle, Anoplophora malasiaca, by an entomogenous fungus, Beauveria brongniartii. N . Field evaluation of hanging polyurethane foam sheet containing B. brongniartii conidia, on citrus trees for the control of adult beetle.

Prospects for the use of biological control agents againstAnoplophorain Europe

“…Certain fungal species can infect insects, and a number of studies have sought to identify such species for Anoplophora . Five species of fungi were found that are pathogenic to Anoplophora spp., of which three species Beauveria bassiana (Balsamo) Vuillemin (Hypocreales: Cordycipitaceae), Beauveria brongniartii (Saccardo) Petch (Hypocreales: Cordycipitaceae) and Metarhizium brunneum Petch (formally M. anisopliae ) (Hypocreales: Clavicipitaceae) can infect both A. chinensis and A. glabripennis . Two strains of Isaria farinosa (Holmskiold) Fries (Hypocreales: Clavicipitaceae) and the microsporidium Nosema glabripennis Zhang (Dissociodihaplophasida: Nosematidae) have been shown to infect A. glabripennis .…”

“…Anoplophora chinensis oviposition slits are generally made at the base of host trees, and so, if the bands are placed below the first branch joint, all newly emerging adults should become infected if they move up the tree into the canopy to feed . Anoplophora glabripennis oviposition pits are found higher up the trunk or on main scaffold branches, so the bands must also be placed higher up the tree in order to infect the emerging adults .…”

“…Anoplophora glabripennis oviposition pits are found higher up the trunk or on main scaffold branches, so the bands must also be placed higher up the tree in order to infect the emerging adults . During a study in China using bands impregnated with B. brongniartii to control A. chinensis , the mortality rate decreased from 84–100% to 55–73% if only half the trees were banded . This suggests that all trees within an infested area must be banded in order to maximise the proportion of adults infected.…”

Improving Contagion and Horizontal Transmission of Entomopathogenic Fungi by the White-Spotted Longicorn Beetle, Anoplophora malasiaca, with Help of Contact Sex Pheromone

“…This species is distributed in Japan [ 3 ] and effective controls are needed because the effect of marketed chemical insecticides is limited. Microbial insecticides offer a solution [ 4 , 5 , 6 , 7 , 8 , 9 , 10 ]. Compared to chemical insecticides, entomopathogenic ones pose minimal risk to nontarget organisms and are environmentally friendly [ 11 ].…”

“…Compared to chemical insecticides, entomopathogenic ones pose minimal risk to nontarget organisms and are environmentally friendly [ 11 ]. Studies performed with fabric bands impregnated with conidia of entomopathogenic fungi are reported [ 8 , 9 , 10 ]. In Japan, non-woven fabric band impregnated with conidia of an entomopathogenic fungus, Beauveria brongniartii, named “Biolisa Kamikiri SLIM”, is commercially available [ 12 ].…”
