Screening for Fall Armyworm (Spodoptera frugiperda J. E. Smith) Resistance in Early‐Maturing Tropical Maize Adapted to Sub‐Saharan Africa

open access: yesPlant Breeding, EarlyView.
ABSTRACT Fall armyworm (FAW) (Spodoptera frugiperda J. E. Smith) has emerged as a serious pest since 2016 in Africa, affecting the food security and livelihoods of millions of smallholder farmers, especially those growing maize. Native genetic resistance to FAW is essential for reducing yield loss.

The pollination ecology and mouthpart morphology of a pollen‐feeding fly Incurviseta cf. maculifrons (Diptera: Lauxaniidae) in the Australian Alpine

open access: yesPhysiological Entomology, EarlyView.
The Lauxaniid fly Incurviseta cf. maculifrons (Malloch, 1925) is a locally abundant but poorly understood flower visitor in the Australian Alpine. We describe the flower visitation, pollen transport, pollen diet and mouthpart morphology of I. cf. maculifrons using field observations, pollen analyses and scanning electron microscopy. I. cf.

Organic Fertilizer Sources Distinctively Modulate Productivity, Quality, Mineral Composition, and Soil Enzyme Activity of Greenhouse Lettuce Grown in Degraded Soil

open access: yesAgronomy, 2023
Intensive greenhouse vegetable production is often associated with a decline of crop productivity due to the increase of soil salinity and/or a reduction of biological fertility.

Effects of Ascorbic Acid Deficiencies on Larvae of \u3ci\u3eLymantria Dispar\u3c/i\u3e (Lepidoptera: Lymantriidae) [PDF]

open access: yes, 2017
We assessed the effects of ascorbic acid and total vitamin deficiencies on growth, food processing efficiencies and survival of larval gypsy moths. Artificial diet lacking ascorbic acid did not alter performance of fourth instars, whereas diet lacking a ...

Dietary Overlap of Sympatric Polyphagous Alpine Grasshoppers Includes Invasive Plant Species

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
The diets of three sympatric grasshopper species were compared using mandible morphological analysis, microhistological examination, and DNA metabarcoding of gut contents. Although mandible morphology differed across species and sexes, dietary divergence was not evident.

The Distribution of Three Broadly Sympatric Species of \u3ci\u3eSymmerista\u3c/i\u3e Moths (Lepidoptera: Notodontidae) in the Great Lakes and Midwest Regions of the United States. [PDF]

open access: yes, 2017
All three superficially inseparable species of Symmerista known to occur in eastern North America are sympatric in, and reach their western limit of distribution in, the southern Great Lakes and Midwest Regions of the United States. In this region two of

Enhancing Stored Wheat Shelf Life: Advances in Storage Technologies, Integrated Pest Management, and Climate‐Responsive Approaches

open access: yesFood and Energy Security, Volume 15, Issue 3, May/June 2026.
ABSTRACT Recent advances in agricultural production and storage systems have contributed to a significant enhancement in annual wheat production and preservation, aimed at satisfying increasing consumer demands. Despite such potential developments, there are still significant post‐harvest losses in stored wheat, induced by destructive pests, grain ...
