Description Consumption and utilization of soybean leaves by the fast versus slow-growing larvae of the cabbage looper, Trichoplusia ni were studied under laboratory conditions. Fast-growing larvae consumed more food/unit of body mass, and gained weight 10 times faster than the slow-growing larvae. Slow-growing larvae were less efficient in consumption and utilization of food, and the differences in indices of food utilization were greater between the fast- and slow-growing larvae on the relatively resistant soybean cultivar, “PI 227687” than on the susceptible cultivar, “Davis”. Implications of differences in growth rates and food utilization by the fast- and slow-growing larvae on resistant and susceptible cultivars are discussed in relation to evolution of new biotypes and host-plant resistance.
