Role of Entomopathogenic Fungus in Pest Management

2014
Insect pests cause enormous damage to our crops. However, insects like other living things have their enemies in nature. Microorganisms like fungi, bacteria, and viruses also play a vital role in checking the insect population. Among which fungi parasitize the insects and cause severe epizootics than bacteria and viruses, and it is distributed ...

Genetic Transformation and Mutagenesis of the Entomopathogenic Fungus Paecilomyces fumosoroseus

Journal of Invertebrate Pathology, 1999
We have developed a DNA-mediated transformation system for the entomopathogenic fungus Paecilomyces fumosoroseus based on resistance to the herbicide glufosinate ammonium. The resistance is provided by the bar gene from Streptomyces hygroscopicus and is under the control of the Aspergillus nidulans trpC promoter and terminator sequences. Frequencies of

Double-stranded RNA in the entomopathogenic fungus Metarhizium flavoviride

Current Genetics, 1999
Bands of dsRNA were detected in five out of seven isolates of the entomopathogenic fungus Metarhizium flavoviride. The identity of these bands was proven by RNase and S1-nuclease treatments. The transference of dsRNA between isolates (from CG291 to CG442) was successfully carried out through forced heterokaryons. Isogenic strains, with or without dsRNA,

First record of an entomopathogenic fungus of tomato leafminer, Tuta absoluta (Meyrick) in Tanzania

Biocontrol science and technology (Print), 2019
Tuta absoluta (Meyrick) is a destructive pest causing adverse environmental and economic effects globally. Management of T. absoluta by synthetic chemicals is of diminutive achievement due to resistance trick of the pest.

High genetic diversity of the entomopathogenic fungus Beauveria bassiana in Colima, Mexico.

Journal of Invertebrate Pathology, 2019
The entomopathogenic fungus Beauveria bassiana is used widely as a biological control agent against a wide range of insect pests globally. In this study, 44 Beauveria isolates from the state of Colima, Mexico harbored in the "Colección de Hongos ...

Genes involved in virulence of the entomopathogenic fungus Beauveria bassiana

Journal of Invertebrate Pathology, 2016
Pest insects cause severe damage to global crop production and pose a threat to human health by transmitting diseases. Traditionally, chemical pesticides (insecticides) have been used to control such pests and have proven to be effective only for a limited amount of time because of the rapid spread of genetic insecticide resistance.

Bioactivity of MWCNT in Conidia of Entomopathogenic Fungus Isaria fumosorosea

Water, Air, & Soil Pollution, 2015
The bioactivity of three kinds of multi-walled carbon nanotubes (MWCNT) towards the conidia of entomopathogenic fungus Isaria fumosorosea was examined in an in vitro study. Commercial—raw and functionalized—carboxylated MWCNT were applied. A fungal conidia suspension was placed in contact with dispersed MWCNT over different time-periods.

Investigations on the destruxin production of the entomopathogenic fungus Metarhizium anisopliae

Journal of Invertebrate Pathology, 2004
The dynamics of cyclic peptide destruxins (dtxs) produced by Metarhizium anisopliae strains V245 and V275 were monitored both on solid and in liquid media. The results showed that both strains did not produce dtxs in large-scale fermenter cultures or solid Czapek Dox (CD) agar.

First record of Aspergillus oryzae as an entomopathogenic fungus against the poultry red mite Dermanyssus gallinae.

Veterinary parasitology, 2019
The poultry red mite, Dermanyssus gallinae, is a blood-feeding ectoparasite that affects egg-laying hens worldwide. Strategies to control this parasite have focused in the use of entomopathogenic fungi, such as Metarhizium anisopliae. However, only a few

Transformation of the entomopathogenic fungus Paecilomyces fumosoroseus with Agrobacterium tumefaciens

Letters in Applied Microbiology, 2006
To test the suitability of the Agrobacterium tumefaciens-mediated transformation (AMT) method with Paecilomyces fumosoroseus, a fungal pathogen that causes diseases in a wide range of insects including whiteflies.Conidia of P. fumosoroseus were successfully transformed to hygromycin B resistance using the hph gene of Escherichia coli as the selectable ...
