Hirsutellin A, a toxic protein produced in vitro by Hirsutella thompsonii.
Microbiology, 1995A toxic protein, hirsutellin A, has been purified from the mite fungal pathogen, Hirsutella thompsonii, using ammonium sulphate precipitation, ion exchange chromatography and gel filtration on Bio-Gel P-10. The protein has been characterized as a monomer with a molecular mass of 15 kDa and an isoelectric point of 105. The amino acid composition and the

Abstract Large quantities of mycelia of Hirsutella thompsonii, a fungal pathogen of the citrus rust mite, Phyllocoptruta oleivora, were produced by use of a submerged culture technique. The mycelia were then fragmented and applied as a foliar spray to orange trees infested with high populations of the citrus rust mite.

Enabling mycelial application of Hirsutella thompsonii for managing the coconut mite
Experimental and Applied Acarology, 2008Laboratory and field studies were conducted to examine the prospect of mycelial application of Hirsutella thompsonii as an alternative to the use of mycelial-conidial formulations of the fungus in the suppression of the coconut mite, Aceria guerreronis.

A liquid medium for the large-scale production of Hirsutella thompsonii in submerged culture
Journal of Invertebrate Pathology, 1972Abstract Comparative nutritional studies showed that dextrose and sucrose at an optimum concentration of 5 mg/ml and 10 mg/ml, respectively, were the most effective sources of carbon (produced the greatest increases in weight) among sugars tested for use in the large-scale production of the fungal pathogen Hirsutella thompsonii in submerged culture.

Calacarus heveae (Feres, 1992) is considered a key pest of the rubber tree Hevea brasiliensis Muell. Arg. (Euphorbiaceae) in the Brazilian states of Sao Paulo, Mato Grosso, Mato Grosso do Sul, Minas Gerais and Goias (Tanzini, 1999). Attacked leaves lose shininess, show tiny chlorotic spots on the upper side and may bear large numbers of mite exuviae ...

AbstractThe mite fungal pathogen Hirsutella thompsonii produces a single polypeptide chain, insecticidal protein named hirsutellin A (HtA) that is composed of 130 amino acid residues. This protein has been purified from its natural source and produced as a recombinant protein in Escherichia coli.

Hirsutella thompsonii, a fungal pathogen of mites. I. Biology of the fungus in vitro
Annals of Applied Biology, 1979SUMMARY Hirsutella thompsonii, a moniliaceous fungus pathogenic to mites, grew and sporulated on sterilised wheat bran. The effects of environmental factors were studied on the fungus grown on potato‐dextrose‐agar (PDA). The fungus was mesothermophilic. Growth, sporulation and conidial germination were best at 25o‐30 oC.

The Varroa mite, Varroa destructor, is recognized as the most serious pest of both managed and feral Western honey bee (Apis mellifera) in the world. The mite has developed resistance to fluvalinate, an acaricide used to control it in beehives, and fluvalinate residues have been found in the beeswax, necessitating an urgent need to find alternative ...

The acaricidal mycopathogen Hirsutella thompsonii has been found to secrete metabolites that are active against female Tetranychus urticae. Specifically, the rose-colored exudate produced on sporulating cultures of Mexican HtM120I strain sterilized female spider mites in a dose-dependent fashion.
