Stored yam chips are attacked by Dinoderus porcellus Lesne, which can cause significant losses. The predator Alloeocranum biannulipes Montr. and Sign. is a potential biological control agent of D. porcellus. The biology, predation and mating behaviour of A. biannulipes were investigated under lab...

Laboratory and field experiments were performed to test several materials on their suitability as carrier for the aerial release of phyroseiid mites. Relatively few mites adhered to the materials. Nevertheless, mites were rettieved in cassava fields after a mass release, using oat flakes as carri...
