Ovipositional and feeding preference of leafhoppers [Empoasca fabae] (Homoptera: Cicadellidae) on Clark soybeans in relation to plant pubescence
- Journal of the Kansas Entomological Society 期刊
- Ovipositional preference of the potato leafhopper, Empoasca fabae (Harris), was determined on eight isolines (pubescent types) of Clark soybeans. In field tests, counts of all leafhoppers on the isolines were used as an index of feeding preference; the glabrous and curled deciduous lines had the highest number of leafhoppers and the dense type the fewest number of leafhoppers. In greenhouse tests, the glabrous line received a significantly greater number of eggs than the other lines, but the curled deciduous line was also highly preferred for oviposition. The dense pubescent soybean line received the least number of eggs.
