“…Comparable selection pressure can occur across crops increasing overall selection pressure for resistance (Roush, 1989;Hernández-Martínez et al, 2009). Furthermore, the coexistence of different crops in the agro-ecosystem, especially soybean and maize, can trigger new feeding preferences in the absence of the main host (Andrews, 1980) despite the fact that S. frugiperda food intake regulation appears to be triggered by a complex of different mechanisms including plant allelochemicals and the existence of its corresponding insect adaptation, and nutrient regulation. Even the alternative explanation of sheltering and predation impact cannot be excluded.…”

“…This availability of different hosts might even result in the selection of insect populations with new food preferences due to different exposure of these insects to a variety of crops (Barros et al, 2010). For example, although soybean is not one of the preferred hosts of S. frugiperda, it is one of the most abundant summer crops in Brazil, which may favor the establishment and environmental colonization of this crop by S. frugiperda (Andrews, 1980;Barros et al, 2010).…”

“…This pest is polyphagous and is found in several countries such as Brazil, Argentina, and the USA (Prowell et al, 2004;Clark et al, 2007), causing economic losses in a variety of crops such as maize (Zea mays L.), soybean (Glycine max (L.) Merrill), cotton (Gossypium hirsutum L.), and beans (Phaseolus vulgaris L.) (Pogue, 2002;Nagoshi, 2009;Bueno et al, 2011). Because of its wide host range, S. frugiperda is one of the most harmful pests threatening annual crops in tropical regions (Andrews, 1980;Cruz et al, 1999). Control of this pest is challenging because possible host plants have different phenologies and are grown during different seasons of the year though in proximity to each other, which can facilitate movement of the pest between crops.…”

We studied Spodoptera frugiperda development using different food sources in the laboratory and field. Newly hatched larvae were fed soybean, cotton, maize, wheat, and oat leaves. An artificial diet was used as the control. Duration of pre-pupal, pupal, and larva-adult period, pupal weight, sex ratio, survival, larva feeding preferences, oviposition preferences, and nutritional quality of different hosts were evaluated. Insects fed on wheat showed the shortest larva-adult period. The insects fed on cotton and soybean had longer larval development cycles and pupae of lower weight. Feeding preference was evident for third instar larvae and did not differ between wheat, oat, maize, and soybean, which were the preferred hosts. Moths oviposited to a greater extent on the upper canopy of wheat than that of other plants in both the no-choice and free-choice tests. Treatments influenced insect growth, food consumption, and digestion when nutritional variables were analyzed. Thus, grasses were better hosts for S. frugiperda development. Cotton was the least preferred food, followed by soybean. The present study can improve our understanding of S. frugiperda in these different crops and help in developing management strategies. Even though S. frugiperda is considered to be polyphagous, this pest is closely associated with grasses (maize, wheat, oat) and has lower potential as a soybean or cotton feeder. Howerver, S. frugiperda food intake regulation appears to be triggered by a complex of different mechanisms. Thus, S. frugiperda can also damage soybean and cotton and adapt to them in the absence of preferred hosts.

Inhibition of electrophysiological response to the pheromone of the fall armyworm, Spodoptera frugiperda

2010

In the search for new control methods for the fall armyworm (FAW), Spodoptera frugiperda (Lepidoptera: Noctuidae), we present the inhibition of the electroantennographic (EAG) response to the pheromone by 3-octylthio-1,1,1-trifluoropropan-2-one (OTFP). As a member of the trifluoromethyl ketones, OTFP is a potent inhibitor of serine esterases, particularly those of insect antennae. Exposure of antennal receptors to OTFP vapors resulted in a decreased amplitude and 2/3 repolarization time (2/3 RT) of the EAG response to the pheromone. The effect was reversible, with the amplitude and repolarization time being recovered upon suppression of the treatment. The non-fluorinated analogue 3-octhylthiopropan-2-one (OTP) did not affect either the amplitude or the 2/3 RT of the EAG response to the pheromone, confirming the key role played by fluorine atoms in this type of chemical. These results may be the basis for new behavioral studies with the aim of considering OTFP in future management strategies of the FAW.
