Abstract The antifeeding effects of 9 Asteraceae plants against three pests were determined. The results indicated that these plants had different antifeeding effects on pests. The antifeeding rate of 1% extract from Synedrella nodiflona,Wedelia chinensis and Ageratum conyzoides were more then 80% at 24h and 48h after feeding Pitris rapae. The first two plants showed 60%-80% antifeeding rate with same concentration at same time after feeding Plitella xylostella. The antifeeding effects were quite low...
