Identifying the landscape drivers of agricultural insecticide use leveraging evidence from 100,000 fields
Open accessAbstract
Significance: Ecological theory predicts simplified agricultural landscapes composed of large-scale, homogeneous cropland will have increased pest problems due to fewer natural enemies and concentrated host plants, which will result in increased pesticide use and associated environmental degradation. Using detailed data from Kern County, California, for 100,000 field-year observations, we parse apart how different components of landscape simplification affect insecticide use. We find insecticide use decreases with increases in crop diversity and increases with field size, whereas the effect of cropland extent depends on the spatial scale. This refined spatial perspective provides unique understanding of how different components of landscape simplification influence insecticide use, and indicates that neither the traditionally conceived “simplified” nor “complex” agricultural landscape is most beneficial to pest control.

Greater crop diversity is linked to higher bird diversity in agricultural landscapes.
“Strobl ( 97 ) found that greater crop diversity is linked to higher bird diversity in agricultural landscapes”
From Environmental impacts of genetically modified crops (2024) · cites this paper as [97]
The Results (p. 3) link greater crop diversity to lower insecticide use, not to bird diversity. A search for bird diversity and avian species richness found no passage in our copy assessing the claimed relationship. (LLM, conf=0.76)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
