ROOT-KNOT NEMATODES FROM ASPARAGUS AND ASSOCIATED BIOLOGICAL ANTAGONISTS IN PERU
2012
A research study on the parasitic nematodes of asparagus and several associated antagonists was carried out in Northern Peru. Nematodes were identified by means of light microscopy and sequencing of the ITS1-2 regions. Nematophagous fungi were isolated from nematode-infested roots or soil, cultured in vitro and maintained in a culture collection for further characterization. The species recovered were mainly root-knot nematodes including Meloidogyne incognita and M. ethiopica. Nematophagous fungi identified through standard morphological methods as well as by ITS sequencing included Drechslerella brochopaga, Lecanicillium psalliotae and Monacrosporium sp. Meloidogyne ethiopica and the antag…
Phylogeny and morphology of Hirsutella tunicata sp. nov. (Ophiocordycipitaceae), a novel mite parasite from Peru
2013
Abstract A new species of Hirsutella was isolated from unidentified mites on Petri plates inoculated with soil and root fragments collected from asparagus rhizosphere at Viru, Northern Peru. The fungus differs from other Hirsutella species by an envelope surrounding the conidium, conidia dimension and DNA sequences. In PDA cultures, the mycelium produced aerial hyphae with conidiogenous cells mainly at right angles, occasionally showing a secondary conidiophore. The solitary conidia are cymbiform, slightly apiculate, 5.0–6.0 × 3.0–4.0 μm. Phylogenetic analyses with partial rRNA and β-tubulin gene sequences confirmed the fungus as an Hirsutella (Ophiocordycipitaceae). Closest species shown b…
