The snail Pseudosuccinea columella participates in the distribution of Fasciola hepatica in the environment by acting as its intermediate host. Therefore, the control of this lymnaeid is one of the ways to prevent hepatic fascioliasis. The objective of this study was to evaluate the susceptibility of P.

Nematode strains of the entomopathogenic family Steinernematidae differ in their ability to infect insects at different temperatures. Survival and infectivity of infective juveniles (IJs) of Steinernema rarum (OLI) were studied after their storage at 23+/-2 degrees C and at 5+/-1 degrees C. Survival at 23+/-2 degrees C was always above 95%.

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.

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 ...

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 .

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.
