larvae of R. reniformis to 1000, 2000, 3000 and 4000 ppm. of the herbicide solution for 8 and 24 hours in each case, did not affect either infectivity or reproduction of the nematode. The saprophagous nematodes killed by EPTC treatment were Acrobeles sp., Acrobeloides sp., Rhabditis sp., Chiloplacus sp

predation took place in a population of 200 prey individuals and when predators starved for twelve days were used at 25-30°C. Acrobeloides sp. Cephalobus sp., Panagrellus redivivus and second stage juveniles of Meloidogyne incognita and Anguina tritici were most preferred by both predators. No preda- tion

. As S. caverna n. sp. is a predator, the nematodes were transferred to an NGM plate that had previously been inoculated with prey species. An unidentified Acrobeloides sp. that was concomitantly isolated from the guano with S. caverna n. sp. was used as the prey (food) species. After the
