Trait Variation between Two Wild Specimens of Pleurotus ostreatus and Their Progeny in the Context of Usefulness in Nematode Control
2022
Pleurotus ostreatus is one of the most widespread mushrooms in the world. It is a valuable and widely cultivated edible mushroom with nematicidal properties. The mycelium of this mushroom produces a toxin that paralyzes nematodes, after which the nematode becomes infected with the filament, resulting in its death. This feature can be put to practical use as a natural nematicidal agent. In this paper, we have described studies on two wild strains of P. ostreatus (PO1, PO2) and the monokaryotic progeny obtained from their fruiting bodies. Monokaryons were crossed with each other within the progeny of one strain (PO1xPO1; PO2xPO2) and of two different strains (PO2xPO1). The growth conditions, …
OBSERVATIONS ON THE BIOLOGY OF A PREDATORY NEMATODE BELONGING TO DIPLOGASTERIDAE
2011
The use of predatory nematodes as biological control agents of phytoparasitic nematodes has been re-evaluated only recently. To be effective, predatory nematodes should be easy to grow, cheap, and available on a commercial scale. In addition, they must show a reproductive rate sufficient to sustain a high population density and a significant longevity and stability for storage. The predators are not phytopathogenic nematodes, and among the positive outcomes of their introduction are remarkable their environment compatibility and safety for other non-target organisms, as well as the ability to search for prey. These features are present in Diplogasteridae. Their adaptability enables them to …
E se il punteruolo affamasse Steinernema carpocapsae?
2023
Rhynchophorus ferrugineus (Olivier 1790) (Coleoptera: Curculionidae), phytophagus of palms, has been used as a model to deepen the knowledge of the host-entomopathogen relationship. The effects of Steinernema carpocapsae (Nematoda: Steinernematidae) on the growth and immunoactivity of R. ferrugineus larvae were compared with another model insect Galleria mellonella L. (Lepidoptera: Pyralidae). Although S. carpocapsae had a negative effect on the weight and mortality of R. ferrugineus, it was not able to replicate in the hemolymph with the same rates found for the moth. In vivo and in vitro effects of S. carpocapsae on the phagocytic responsesof the hemocytes of R. ferrugineus and G. mellone…
