The Fall Armyworm and Larger Grain Borer Pest Invasions in Africa: Drivers, Impacts and Implications for Food Systems

Biology
Simple Summary The fall armyworm and larger grain borer are two of the main invasive cereal insect pests of cereal crops in Africa. These pests cause successive synergistic damage to maize in the field and after harvesting, resulting in huge food losses ...

Bioactive Volatiles From Push-Pull Companion Crops Repel Fall Armyworm and Attract Its Parasitoids

Frontiers in Ecology and Evolution, 2022
Fall armyworm, Spodoptera frugiperda, is a serious invasive pest in Africa but “Push-Pull” companion cropping can substantially reduce infestation. Here, we elucidate the underpinning chemical ecology mechanisms.

Sublethal Effects of Emamectin Benzoate on Fall Armyworm, Spodoptera frugiperda (Lepidoptera: Noctuidae)

Agriculture, 2022
Fall armyworm (FAW), Spodoptera frugiperda (Lepidoptera: Noctuidae), is a highly invasive polyphagous pest that causes great economic losses to agricultural production. Emamectin benzoate (EMB) is one of the most popular biopesticides with high antipest,

Silicon Dioxide (SiO₂)-Based Defense Induction in Maize against Fall Armyworm (Spodoptera frugiperda)

Biology and Life Sciences Forum, 2023
Agricultural development is one of the most powerful tools to end extreme poverty but agriculture-driven growth, poverty reduction, and food security are at risk.

Comparisons of fall armyworm haplotypes between the Galápagos Islands and mainland Ecuador indicate limited migration to and between islands

Scientific Reports, 2021
The migration of the fall armyworm (Spodoptera frugiperda) is of topical interest because of its recent introduction and rapid dissemination throughout the Eastern Hemisphere.

Impact of Temperature Change on the Fall Armyworm, Spodoptera frugiperda under Global Climate Change

Insects, 2022
Simple Summary The fall armyworm (FAW) is of tropical–subtropical origin and defined as one of the most destructive agricultural pests globally. Superior migratory performance, reproductive ability and adaptability make it successful in causing a serious

Impact of Rice and Potato Host Plants Is Higher on the Reproduction than Growth of Corn Strain Fall Armyworm, Spodoptera frugiperda (Lepidoptera: Noctuidae)

Insects, 2022
Simple Summary Since 2016, the fall armyworm (FAW), an invasive pest native to tropical and subtropical regions of the Americas, has invaded Africa and further spread into Asian countries.

Modeling Control of Invasive Fire Ants by Gene Drive

Advanced Science, EarlyView.
The fire ant Solenopsis invicta is characterized by exceptional invasive capabilities, rendering conventional control ineffective. Here, we explore the use of homing suppression gene drive in fire ants by developing a spatially explicit model. Overall, these results show that target population suppression requires an extended time scale, but that gene ...

The evolutionary process of invasion in the fall armyworm (Spodoptera frugiperda)

Scientific Reports, 2022
The fall armyworm (FAW; Spodoptera frugiperda) is one of the major agricultural pest insects. FAW is native to the Americas, and its invasion was first reported in West Africa in 2016.

Cell‐Penetrating Poly(disulfide)s

Helvetica Chimica Acta, EarlyView.
The first 10 years of cell‐penetrating poly(disulfide)s (CPDs) are reviewed comprehensively. CPDs are prepared by ring‐opening polymerization of cyclic disulfides. The many sidechain structures and diverse biological applications realized so far beyond the original arginines identify CPDs as the most popular current delivery system that operates with ...
