“…Survival of S. frugiperda caterpillars with cotton and corn leaves was lower than that of 72% and 98% with leaves of the Acala 90 cotton and BRS catingueiro corn [ 18 ] and 89% and 91% with leaves of cotton Shyuan 321 and corn Zhengdan 958 [ 21 ], respectively, at similar temperatures. This indicates that variations in survival are due to differences between the cotton and corn cultivars, as the nutritional quality varies between species [ 47 ] and varieties [ 48 ] of host plants.…”

“…The longer duration of the larva and pupa stages of S. frugiperda with cotton seems to indicate that the leaves of this plant are nutritionally less adequate than those of castor bean and corn. However, the additional instar with cotton leaves and corn indicates adverse conditions when larvae cannot reach a specific size threshold for metamorphosis [ 52 ] because of the cumulative toxic effect of gossypol and hydroxamic acid (HA) in cotton and corn leaves, respectively [ 39 , 48 ]. The duration of the larval stage of S. frugiperda with cotton leaves was longer than the 18 [ 14 ], 21 [ 18 ] and 21 [ 21 ] days with cotton leaves of FMT 701, Acala 90 and Shiyuan 321, respectively, at similar temperatures.…”

The polyphagy of Spodoptera frugiperda (Lepidoptera: Noctuidae) renders its control difficult because variations in the phenology of host plants grown in different seasons of the year and near each other can facilitate the movement of this pest between crops. The objective of this work was to examine certain biological characteristics of S. frugiperda fed on an artificial diet or on cotton, castor bean, or corn leaves. The experimental design was in randomized blocks, with four treatments represented by S. frugiperda caterpillars fed an artificial diet (T1) or pieces of cotton (T2), castor bean (T3) or corn (T4) leaves with five replications (five caterpillars per replication). The duration and survival of the egg, larva, pre-pupa, pupa and egg-adult period and the reproductive characteristics of this insect were determined. The survival, development and reproduction data of S. frugiperda originated from individuals reared with cotton and castor bean leaves were lower than those fed on corn leaves or an artificial diet. The number of nonviable eggs laid by females originated from caterpillars fed on castor bean leaves was higher than those fed on cotton and corn leaves or an artificial diet. The very higher number of unviable S. frugiperda eggs resulting from castor leaves can reduce outbreaks of this pest in cotton and corn crops after the cultivation of that plant, or by intercropping with this plant, in the main producing regions of Brazil.
