The Role of Larval Nutrition in Shaping Pheromone Composition in Fall Armyworm.

ABSTRACT: The fall armyworm (FAW), Spodoptera frugiperda (JE Smith), is polyphagous that enables it to develop on different hosts, likely has a host-induced impact on its developmental biology as well as pheromone composition and production. While the effect of geographic variation on the components of FAW pheromone has been extensively studied, fewer studies have explored the influence of larval diet on the FAW pheromone composition. We conducted a laboratory study that examined the pheromone composition and production of FAW reared on horticultural plants, both known and potential hosts, in Australia. FAW larvae were raised on sweetcorn leaves/kernel, bean leaves/pod, okra leaves/fruits, strawberry leaves, capsicum fruits/leaves, and artificial diet. The headspace and pheromone gland compounds wer
