Soil nematode communities in grasslands [PDF]

open access: yes, 2007
This thesis summarizes the results of five studies investigating the effect of plant species on soil nematode communities in grasslands. Nematodes (roundworms) are ubiquitous members of the soil fauna and have been much used as indicators of soil ...

Biocontrol potential of naturally occurring entomopathogens against Maladera formosae in corn–soybean rotated systems

open access: yesPest Management Science, Volume 81, Issue 8, Page 4894-4903, August 2025.
We isolated three insect‐killing nematodes from Maladera formosae infested corn–soybean rotated fields, Heterorhabditis bacteriophora, Pristionchus sp., and Steinernema carpocapsae. Results from greenhouse and field microcosm studies indicate all three nematodes can infect and kill M. formosae grubs and persist through winter.

Efficacy of Heterorhabditis bacteriophora Against Diapausing Larvae of the Truffle Beetle, Leiodes cinnamomeus

open access: yesJournal of Applied Entomology, Volume 149, Issue 7, Page 1105-1108, August 2025.
ABSTRACT The truffle beetle, Leiodes cinnamomeus, is the most important pest in black truffle (Tuber melanosporum) plantations. Adults and mycophagous larvae are active during autumn and winter, while diapausing larvae are not. Previous laboratory studies demonstrated the high virulence of the entomopathogenic nematode (EPN) Heterorhabditis ...

Change in the degree of infestation of parasitic nematodes in Grey Seals Halichoerus grypus from Froan, Norway

open access: yesFauna Norvegica, 1988
Change in nematode infestation in stomachs of Grey Seals caught at the breeding ground at Froan on the coast of Sør-Trøndelag county, Norway, is recorded. The abundance of nematodes decreased from 1977/78 to 1982/84. In the first period more than 50% of

Biochar Suppresses Growth, Pupation and Eclosion Success of a Specialist (Manduca sexta) and a Generalist (Spodoptera frugiperda) Insect Herbivore

open access: yesJournal of Sustainable Agriculture and Environment, Volume 4, Issue 2, June 2025.
ABSTRACT Biochar is a charcoal‐like substance made by the pyrolysis of organic material from agricultural and forestry waste. While biochar is well documented for altering soil physicochemical conditions, few studies have investigated its possible effects on the management of arthropod pests.

Elaphostrongylus sp. (Nematoda, Protostrongylidae) and other helminths in faeces of moose (Alces alces (L.) in North Norway

open access: yesFauna Norvegica, 1983
Faecal samples collected from 103 moose (Alces alces) in Troms and Finnmark counties during the hunting season of September - October 1975 were examined. The faeces of all moose older than one year contained eggs or larvae of gastro-intestinal nematodes.

Fluralaner treatment of chickens kills the southern house mosquito, Culex quinquefasciatus

open access: yesMedical and Veterinary Entomology, Volume 39, Issue 2, Page 385-392, June 2025.
Chickens treated with fluralaner, fenbendazole or ivermectin did not repel Culex quinquefasciatus from feeding. The mortality of Culex quinquefasciatus feeding on fluralaner‐treated chickens was significantly higher than that of those fed on control chickens at 3 and 7 days post‐treatment.
