frugiperda exhibited cannibalism to a larger degree than the stemborers species, especially at the late instars. Results of the intraspecific interaction indicated that S. The experimental insect larvae were reared on maize leaves and monitored until the last developmental stage where cannibalism and/or intraguild predation, larval survival, and relative growth rate were recorded. ![]() frugiperda were conducted under laboratory conditions. frugiperda or any of the stemborers or pairwise species combinations with S. Experiments involving treatments with either single species of S. The present study was aimed at assessing the interactions between larvae of fall armyworm ( Spodoptera frugiperda) and maize stemborers (native to Africa, Busseola fusca, and Sesamia calamistis and native to India, Chilo partellus) in relation to cannibalism and intraguild predation when they utilize the same resource. However, the relationship between cannibalism and intraguild predation, and the costs and benefits of such behaviours, is difficult to establish within insect communities, and little is known about how such behaviours are affected by invasive species. Cannibalism and intraguild predation can play important roles in determining spread and survival or death of organisms which share the same resource.
