Studies on the survival of eggs and infective larvae of Ostertagia ostertagi and Cooperia oncophora in herbage

Field investigations were carried out from between 1971 and 1974, to determine the effect of Swedish weather conditions (Stockholm) on the development and survival of eggs and infective larvae of a mixture of Ostertagia and Cooperia. Faeces containing eggs or infective larvae were spread on plots monthly for 2 years. Three times (January, July, October) eggs and larvae disseminated in liquid cattle manure were spread on plots to compare the effect of dissemination of eggs and larvae. On plots contaminated with egg-containing faeces between November and February only a few infective larvae were generally found in the herbage during the following spring and summer. Infective larvae were found during 10-20 months in the herbage from plots contaminated with faeces containing eggs and larvae between March and October, and with larvae-containing faeces also between November and February. Viable larvae in faeces from contaminated plots were found during 5-9 months on plots contaminated in October-March and during 3-8 months on plots contaminated in April-September. Generally, smaller numbers of larvae were recovered from plots contaminated with eggs and larvae disseminated in liquid manure than from plots with solid pads. The results are compared with those obtained in other countries with different meteorological conditions, and the differences are explained with the aid of bioclimatographs.

Adult sex ratios of S. mansoni in mice were biased toward males (3:1) despite the finding that sex ratios of miracidia were 50:50. The adult male bias was caused by greater male infectivity of miracidia for Biomphalaria glabrata and cercariae for...
