Abstract: The survival of Ditylenchus destructor following storage of infected hulls and seeds of groundnut cv. Sellie and infested soil, and the capacity of D. destructor to undergo complete dehydration and enter in a state of anhydrobiosis was investigated. The results show that D. destructor can survive in the field in the absence of host plants and in hulls left in the field after harvest for at least 28 to 32 weeks. In contrast, nematode numbers in fragmented hulls and fragmented or whole seeds stored in paper bags at 10-degrees-C (whole seeds) or 22-degrees-C (fragmented hulls and seeds) decreased with increasing storage time, especially during the first 12 weeks. Very few nematodes survived in whole seeds stored in paper bags at 10-degrees-C but the surviving nematodes were able to build up large populations and to cause damage. Finally, the results show that the freshness of the tissues played an important role in the efficiency of the soaking method : stored hulls and seeds must be soaked longer than 24 h to make a reliable estimate of the number of nematodes present.
