This study determined the pathogenicity of Metarhizium anisopliae strain SD-3 against invasive red palm weevil (RPW), Rhynchophorus ferrugineus Olivier (coleoptera:curculionidae) larvae in Hainan Province, China. Inoculation of 1 × 108 conidia/mL caused 100 % mortality of R. ferrugineus, indicating that the conidia of strain SD-3 were highly virulent. The process of invasion mechanism was showe...

BACKGROUND Metarhizium anisopliae strain IRAN 437C is one of the most virulent fungal isolates against house fly, Musca domestica. The objective of this study was to determine the interaction of this isolate with sublethal doses of spinosad against housefly. METHODS In adult bioassay, conidia of entomopathogenic fungus were applied as inoculated bait at 10(5) and 10(7) spore per gram and spin...

Six Beauveria bassiana (Balsamo) Vuillemin isolates were obtained from Reticulitermes flavipes (Kollar) and Coptotermes formosanus Shiraki in the U.S. and China. These isolates, plus the B. bassiana isolate 26037 from American Type Culture Collection that was isolated from Colorado potato beetle (Leptinotarsa decemlineata (Say)) were compared against C. formosanus and R. flavipes in the laborat...

Laboratory soil bioassays were performed at economic field rates for in-furrow (3.85 x 10(6)spores/g dry soil) and broadcast (3.85 x 10(5)spores/g dry soil) applications with three isolates of Metarhizium anisopliae (F52, ATCC62176, and ARSEF5520) and one isolate of Beauveria bassiana (GHA). All isolates tested were infective to second instar Delia radicum (L.). The conditionally registered M. ...

the western flower thrips frankliniella occidentalis, an important greenhouse pest, has acquired rapid resistance to the chemical pesticides. therefore, biological control is worth consideration as an alternative control method. among the biological control agents, entomopathogenic fungi showed to be quite successful in some occasions. in this study, three iranian isolates of metarhizium anisop...

Wholesale container-grown ornamentals are often maintained at the nursery for at least two growing seasons and are subject to infestation by black vine weevil (BVW), Otiorhynchus sulcatus F., for several months each year. Therefore, a potting media amendment aimed at controlling BVW needs to persist for an extended period of time. These studies were conducted to determine the persistence and ec...

subterranean termites are one of the most important pests of buildings, historic monuments and agricultural crops in some parts of iran. using entomopathogenic fungi as microbial insecticides is usually a part of biological control and insect pest management. the pathogenicity of entomopathogenic fungus, metarhizium anisopliae (metschnikoff) sorokin (demi 001) isolated from rhynchophorus ferrug...

Entomopathogenic fungi were collected from soil in four adjacent habitats (oak forest, agricultural soil, pine reforestation and chaparral habitat) in Saltillo, México using the insect bait method with Tenebrio molitor (L.) (Coleoptera: Tenebrionidae) larvae as bait. Overall, of the larvae exposed to soil, 171 (20%) hosted Beauveria bassiana (Balsamo) Vuillemin (Hypocreales: Cordycipitaceae), 2...

To supply essential information for improving mass production and biocontrol effi cacy, two-stage cultivation on agar plates was used to evaluate the environmental conditions affecting mycelial growth and sporulation of seven biocontrol fungi. Maximum growth and sporulation occurred on acid media for Paecilomyces (Pa.) lilacinus IPC-P, Pochonia (Po.) chlamydosporia HSY-12-14, and Lecanicillium ...
