We investigated the prevalence of entomopathogenic fungi associated with leaf-cutting ant colonies in a small area of tropical forest in Panama. There was a high abundance of Metarhizium anisopliae var. anisopliae near the colonies. Beauveria bassiana was also detected in the soil, Aspergillus flavus in dump material, and six Camponotus atriceps ants were found infected with Cordyceps sp. Based...
Chemical insecticides have been commonly used to control agricultural pests, termites, and biological vectors such as mosquitoes and ticks. However, the harmful impacts of toxic chemical insecticides on the environment, the development of resistance in pests and vectors towards chemical insecticides, and public concern have driven extensive research for alternatives, especially biological contr...
The beet armyworm Spodoptera exigua (Lepidoptera: Noctuidae) is difficult to control using chemical insecticides because of the development of insecticide resistance. Several pest control agents are used to control the beet armyworm. Entomopathogenic fungi are one of the candidates for eco-friendly pest control instead of chemical control agents. In this study, among various entomopathogenic fu...
Expressed sequence tag (EST) libraries for Metarhizium anisopliae, the causative agent of green muscardine disease, were developed from the broad host-range pathogen Metarhizium anisopliae sf. anisopliae and the specific grasshopper pathogen, M. anisopliae sf. acridum. Approximately 1,700 5' end sequences from each subspecies were generated from cDNA libraries representing fungi grown under con...
Abstract This study aims to determine the influence of three types beneficial fungi with various concentration application on shallot production and pest attacks. research was carried out at Plant Disease Laboratory Teaching Farm, Faculty Agriculture, Hasanuddin University, from September November 2022. arranged in a split plot design. The main plots are fungi, namely Trichoderma asperellum, Be...
BACKGROUND The protective effect of two isolates of an entomopathogenic fungus, Metarhizium anisopliae (DEMI 002 and Iran 437C) on the adult stage of Varroa destructor was evaluated in comparison with fluvalinate strips in the field. METHODS A total of 12 honey bee colonies were provided from an apiculture farm. The selected hives were divided into 4 groups (3 hives per group). The first grou...
to evaluate the effect of metarhizium anisopliae and trichoderma harzianum on root knot nematode (meloidogyne javanica) in tomato, experiments was performed under controlled as well as greenhouse conditions. volatile and non-volatile tests showed that there is no inhibitory effect against every one of each biocontrol agents. on the larval mortality and inhibition of egg hatching, a laboratory t...
The effect of Metarhizium anisopliae (Metschnikoff) Sorokin strain ESC-1 alone and in combination with sublethal doses of commercial formulations of chlorpyrifos, propetamphos and cyfluthrin on mortality of CSMA strain of German cockroach, Blattella germanica (L.), was determined by conducting in vivo studies that included 3 bioassays. Spores of M. anisopliae cultured on SDAY media had germinat...
Within-host competition is an important factor in host-parasite relationships, yet most studies consider interactions involving only single parasite species. We investigated the interaction between a virulent obligate entomopathogenic fungus, Metarhizium anisopliae var. anisopliae, and a normally avirulent, opportunistic fungal pathogen, Aspergillus flavus, in their leaf-cutting ant host, Acrom...
Title of Dissertation: USING THE FUNGUS METARHIZIUM ANISOPLIAE AS A MODEL SYSTEM TO STUDY THE ROLE OF GENE DUPLICATION, DIVERGENCE AND EXPRESSION IN ADAPTING TO PATHOGENICITY. Gang Hu , Doctor of Philosophy 2005 Directed By: Professor Raymond J. St. Leger Department of Entomology Fungal pathogens have been recorded for virtually all groups of multicellular organisms. They are the major cause of...
