Abstract
AbstractWhite grubs are root feeding larvae of beetles (Coleoptera: Scarabaeidae) that are sporadic pests in agriculture and can lead to economic damage. The grubs feed on the roots of plants, while the adult beetle can bore into underground stems, as well as cause defoliation of plants. Sporadic incidence of larvae with symptoms of nematode infections were detected in wattle and sugarcane plantations in the KwaZulu-Natal province of South Africa. The larvae with infection symptoms were isolated, washed, and put on water traps to collect infective juveniles of possible nematode infections. Three species of entomopathogenic nematodes (EPNs) were isolated from the white grub larvae. These includedSteinernema bertusiisolated fromMaladerasp. 4.,Oscheius myriophilafromMaladerasp. 4 andSchizonchya affinis,andSteinernema fabiiisolated fromMaladerasp. 4.,Pegylis sommeri,andS. affinis.Of theseS. fabiiwas the most common species in the sample (87%). This is the first report of such a high diversity of locally occurring EPNs found naturally associated with white grub species in this region of South Africa.
