White clover, Trifollun repens, was grown in sterlllzed sóH inoculated wlth either Heterodera trifolil, Heloldogyne hapla or Pratylenchus penetransl At monthly Inter-vals the c!over was cut and welghed; crude protein was estlmated once. Ali 3 specles were found to damage white clover. Leaf productlon was reduced to 30% of that ln the Controls by H. trifolil and H. hapla and to 45% by PT penetrans. H, trl/olll Infestatlon caused a reduction Tn tKe number of Rhlzoblum nodules on the roots and ln the crude protein extent of roots and leayes.

The llfe-cycle of Heterodera lespedezae (a new specles to be descrlbed later) was studled on Kobe lespedeza at 75°P. Second-stage larvae entered the roots ln 2 days and after 8 days had swoilen and begun the second moult. By the tenth day thlrd-stage larvae were fully developed, the fourth-stage had developed by the 16th day and the lemon-shaped adult by the 22nd day. Eggs were deposlted on the 36th to 38th day. No males were found. Both Kobe and Korean lespedeza were hosts and also red and white cloyers: 3 other legumlnous plants and 3 cereals were not hosts.
