Vertical distribution of trichostrongylid larvae on herbage and in soil


, : Vertical distribution of trichostrongylid larvae on herbage and in soil. International Journal for Parasitology 16(3): 241-244

The vertical migration of third stage trichostrongylid larvae (L3) on herbage was studied at controlled temperatures and humidities to help quantify the relationship between weather and the movement of L3 onto pasture. Pots of grass and clover were seeded on top of the soil with approx. 1000 L3 of Teladorsagia spp. and Trichostrongylus spp. of sheep nematodes. Pots were sampled for viable L3 at daily intervals over 4 days. On average we recovered 8 times more L3 in soil than on herbage, and the proportion of L3 on herbage did not increase significantly (P = 0.44) with time, that is there was no significant positive migration from soil onto herbage. We recovered a mean of 20.0% of the initial population of L3 over 4 days. Only 2.0% of these were on herbage, with 1.3% found below 2 cm. Seventy-one percent of the L3 which were recovered were concentrated within 2 cm of the soil-herbage interface. Recovery of L3 on herbage was significantly (P = 0.001) dependent on temperature and humidity. There was no significant (P > 0.30) difference in the percentage of L3 recovered from grass and clover. Neither the ratio of Teladorsagia spp. to Trichostrongylus spp. in the L3 populations nor herbage density significantly affected percentage of L3 found on herbage.
