Investigation and characterisation of diamide insecticide resistance conferred by target-site mutations in the Ryanodine Receptor of lepidopteran pests [PDF]

, 2019
Lepidopteran crop pests such as Tuta absoluta, Chilo suppressalis, Spodoptera frugiperda and Plutella xylostella are becoming increasingly problematic, as populations colonise new regions of the globe.

Knockdown resistance to DDT and pyrethroids: from target-site mutations to molecular modelling

, 2008
Naturally derived insecticides such as pyrethrum and man-made insecticides such as DDT and the synthetic pyrethroids act on the voltage-gated sodium channel proteins found in insect nerve-cell membranes.

How are educational interventions delivered at scale? A systematic mapping review

Review of Education, Volume 14, Issue 2, August 2026.
Abstract Scaling up educational interventions remains a central yet under‐theorised challenge in educational research. Although conceptual frameworks outline principles for successful scale‐up, evidence on how scaling is operationalised in practice has not been systematically synthesised.

Polymorphisms in Gag spacer peptide 1 confer varying levels of resistance to the HIV-1 maturation inhibitor bevirimat [PDF]

, 2010
Background: The maturation inhibitor bevirimat (BVM) potently inhibits human immunodeficiency virus type 1 (HIV-1) replication by blocking capsid-spacer peptide 1 (CA-SP1) cleavage. Recent clinical trials demonstrated that a significant proportion of HIV-

Fitness costs associated with evolved herbicide resistance alleles in plants [PDF]

, 2009
Predictions based on evolutionary theory suggest that the adaptive value of evolved herbicide resistance alleles may be compromised by the existence of fitness costs.

ACCase-inhibitor resistance in bearded sprangletop (Leptochloa fusca spp. fascicularis) associated with target-site mutations in rice monoculture

Notulae Botanicae Horti Agrobotanici Cluj-Napoca
The presence of weeds is the most serious problem in rice (Oryza sativa L.) cultivation, which is exacerbated by the evolution of herbicide-resistant weed populations. In a whole-plant pot experiment, the possible resistance evolution in a population of

Non-target site-based resistance to tribenuron-methyl and essential involved genes in Myosoton aquaticum (L.)

BMC Plant Biology, 2018
Background Water chickweed (Myosoton aquaticum (L.)) is a dicot broadleaf weed that is widespread in winter fields in China, and has evolved serious resistance to acetolactate synthase (ALS) inhibiting herbicides. Results We identified a M.

Impacts of Migration as Adaptation: Assessing Translocal Social Resilience in Eastern, Northern and Greater Accra Regions, Ghana

Population, Space and Place, Volume 32, Issue 5, July 2026.
ABSTRACT Migration is increasingly recognised as an adaptive strategy to enhance social resilience amid environmental and socioeconomic stressors. However, systematic assessments of its impact on both migrants and their households remain limited. This study applies the translocal social resilience framework to analyse migration outcomes across origin ...

The Unsung Champions of Evolution: Weeds and Their Management in Agricultural Systems

Agriculture
The history of weeds is closely intertwined with the development of agriculture. As early farmers began to select crops, weeds emerged as formidable competitors, evolving alongside them in a continuous struggle for survival.

Camera trap distance sampling for density estimation of tiger prey in a Sumatran ecosystem restoration concession

Wildlife Biology, Volume 2026, Issue 4, July 2026.
Estimating prey species densities is critical for implementing effective tiger Panthera tigris recovery strategies. Several statistical models exist for density estimation of unmarked species from camera trap data, all of which rely on the random placement of cameras.
