Abstract

DAMIN, Silvana; ALVES, Luis Francisco Angeli; BONINI, Andreia Kusumota  and  ALEXANDRE, Talita Moretto. In vitro assay on homeopathic solutions on Metarhizium anisopliae (Metsch) Sorok (Ascomycota: Clavicipitaceae). Arq. Inst. Biol. [online]. 2015, vol.82, pp.1-8.  Epub Jan 12, 2016. ISSN 1808-1657.  https://doi.org/10.1590/1808-1657001142013.

This study aimed to evaluate the in vitro effect of homeopathic solutions Arsenicum Album 24CH; Calcarea carbonica 30CH; Kali iodatum 100CH;Phosphorus 3CH; Silicea 30CH;Staphysagria 6, 30 and 100CH; Spodoptera frugiperda 30CH; Sulphur 100 and 200CH andThuya occidentalis 200CH on biological parameters of the fungus Metarhizium anisopliae . The solutions were diluted in sterile distilled water (0.1%) and were sprayed on the previously inoculated fungus on PDA culture medium. Germination, colony forming units, vegetative growth, conidial production and insecticidal activity of the fungus against larvae of Diatraea saccharalis (Lepidoptera: Crambidae) were evaluated. Homeopathic solutions did not affect negatively the parameters evaluated. Thus, all treatments were considered compatible to the fungusM. anisopliae.

Keywords : entomopathogenic fungus; dynamized solution; species conservation; compatibility.
