Effect of root extracts of resistant pasture plants on the feeding and survival of black beetle larvae, Heteronychus arator (Scarabaeidae)



Effect of root extracts of resistant pasture plants on the feeding and survival of black beetle larvae, Heteronychus arator (Scarabaeidae)



New Zealand Journal of Zoology, 51: 173-175



Crude root extracts of 5 pasture legumes that are resistant to Heteronychus arator (F.) (red clover, white clover, lupin, lucerne and Lotus pedunculatus) significantly reduced feeding by larvae when incorporated into an artificial medium containing a strong feeding stimulant. The same extracts were toxic when administered orally. Lucerne and L. pedunculatus contained particularly active feeding deterrents and toxins.
