Research Notes
In South Asia, the fall armyworm (Spodoptera frugiperda) is an invasive pest. The current research examines the current farming management practices and documents farmers’ opinions of fall armyworm in India, Pakistan, Sri Lanka, and Nepal. To assess current agricultural practices, identification of the fall armyworm and its damage, management, capacity-building initiatives, and support from government …

Gynandromorphism is a phenomenon in which an individual develops with sexual mosaic of male and female traits. It is a rare phenomenon that has been reported in certain group of organisms viz., arthropods, birds, reptiles, amphibians, mammals. Gynandromorphs are expressed generally in two ways, bilateral and non-bilateral (sexual mosaics). In insects, bilateral gynandromorphs are most …

The fall armyworm, Spodoptera frugiperda (J. E. Smith, 1797), has become one of the most devastating pests in the world with diverse host range. To develop effective integrated management strategies against S. frugiperda, it is crucial to know its alternative host plants. In this study, we provide the first information on the occurrence of S. …

We evaluated maize landraces and hybrids usually cropped by African farmers for resistance to FAW larvae feeding. We did not find differences regarding leaf damage but some differences in terms of preferences and larval development were recorded.

Currently in Africa, there is no appropriate maize genotype, scientifically proven to be resistantto FAW since it’s a new pest in Africa. It’s therefore apparent that there’s a critical need toscreen for promising maize genotypes with FAW native resistance breeding .To address this gap, the International Maize and Wheat Improvement Center (CIMMYT) accelerated efforts to …

Bacillus thuringiensis vegetative insecticidal proteins (Vip3A) have been recently introduced in important crops as a strategy to delay the emerging resistance to the existing Cry toxins. The mode of action of Vip3A proteins has been studied in Spodoptera frugiperda with the aim to characterize their binding to the insect midgut. Immunofluorescence histological localization of Vip3Aa …

Several species of herbivores feed on maize in field and storage setups, making the development of multiple insect resistance a critical breeding target. In this study, an association mapping panel of 341 tropical maize lines was evaluated in three field environments for resistance to fall armyworm (FAW), whilst bulked grains were subjected to a maize …

Abstract Fall armyworm (Spodoptera frugiperda (J. E. Smith)) (FAW) is a petrifying invasive pest of maize (Zea mays L.) in Africa. Ten tropical maize accessions from the International Plant Genetic Resources Institute (IPGRI) collections and a check (Ikom White variety) were studied, under rainfed conditions, in a multi-environment trial (MET) to assess their responses to …

Bigger, faster, stronger: Implications of inter-species interactions for IRM of lepidopteran pests of Bt maize in Africa A hypothetical scenario of mixed populations of Busseola fusca (Fuller) (Lepidoptera: Noctuidae), Chilo partellus (Swinhoe) (Lepidoptera: Crambidae) and Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) was used as model to investigate the potential effects of mixed populations of lepidopteran …
