Environmental Entomology, 1988
A laboratory study determined that Spodoptera exigua (Hubner) adults infected with the entomogenous nematode Steinernema feltiae Filipjev dispersed up to 11 m from the site of infection. After dispersal and death of the host, nematode progeny developed within the moth cadavers, moved into the soil, and infected larvae of S. exigua .

Approximately 1000 specimens representing more than 30 species and strains of the family Steinernematidae, from Australia, North and South America and Europe were investigated by scanning electron microscopy to determine the structure of the lateral field of the infective juveniles.

Abstract Under laboratory conditions, the nematodes Neoaplectana carpocapsae and Heterorhabditis heliothidis were able to infect and develop inside the hemocoel of terrestrial isopods belonging to the genus Porcellio. Armidillidium vulgare was also infected by N. carpocapsae , but this host was less susceptible than Porcellio .

Nematologica, 1994
A laboratory test for primary screening of large numbers of Heterorhabditis isolates for low-temperature infectivity is described. The cold active isolate HF85 was used for reference. Preliminary studies showed that, at 9°C, Galleria mellonella in sand columns or Tenebrio molitor on filter paper identified much the same group of isolates as cold ...

Experientia, 1996
Insect-parasitic nematodes possess many of the attributes of ideal biological control agents, but intolerance to extreme temperatures can restrict their use. We examined whether heat-shock treatments could improve nematode survival and infectivity at temperatures that normally inhibit their activity (35 and 40 degrees C).

Entomopathogenic nematode species of Steinernema carpocapsae, Steinernema riobrave, or Heterorhabditis bacteriophora were used to compare survival and infectivity among infective juveniles (IJs) emerging in water from hosts in White traps (treatment a), emerging in sand from hosts placed in sand (treatment c), and emerging from hosts placed on a mesh ...

Abstract The DD-136 strain of Neoaplectana carpocapsae is capable of continued movement over dry surfaces at 35 and 5 C if relative humidity (RH) ranges above 90%. It can also live in the field on foliage for several hours at night and up to 24 days in bark beetle tunnels in pine bolts.

In orchards, in cases where the insect pests are concentrated under the canopy, entomopathogenic nematodes can be applied as infected host cadavers. This study evaluated the distribution of Heterorhabditis baujardi Phan, Subbotin, Nguyen & Moens strain LPP7 applied as one or 15 host cadavers per plot in a guava orchard.

Specimens of the African snail Achatina fulica, collected in Bucaramanga, Colombia, were examined for parasites. Numerous specimens of Caenorhabditis briggsae were collected from the digestive tract of the snails and identified by the structure of male spiculum, caudal bursa, gubernaculum and precloacal lip in males, triangular tooth in metarhabdion ...
