Green Cloverworm Leaf Consumption on Greenhouse and Field Soybean Leaves and Development of a Leaf-Consumption Model12

Abstract
Leaf consumption by Plathypena scabra (F.) was measured at various temperatures. Leaf consumption by male and female larvae was significantly different, with an average consumption of 116.9 cm2. A green cloverworm leaf-consumption model was established that related larval leaf-feeding to development. Consumption of greenhouse and field leaves also was compared and found significantly different. Consumption of field leaves was only 46.1% of the consumption of greenhouse leaves.
