Laimydorus Siddiqi, 1969
Note: the genus name is an anagram of Dorylaimus!
Aquatic and moist habitats.
Categorized as an omnivore (Yeates et al., 1993) and as a predator (Bilgrami
and Gaugler (2005).
Feeding activities of the predatory nematodes
baldus and Discolaimus major preying on
were studied under laboratory conditions. Discolaimus major
killed more prey, and fed and aggregated longer than L. baldus.
Predatory activities were greatest at 30◦C. Predators
starved for 6 days detected prey rapidly and aggregated at the feeding site
Predators were increasingly efficient at finding prey as prey density
Prey search and predation abilities of L. baldus and D.
major were governed regulated by temperature, prey density, starvation and
prey incubation (Bilgrami and Gaugler, 2005). Predators starved for 10
days exhibited maximum response to the presence of prey. Predators
detected prey kairomones at distances of 2-3 cm on agar plates (Pervez and
