Apple orchards using heavy pesticide schedules had 68% fewer insects and collapsed pollinator networks compared to untreated graveyards next door. Weeds like mustard became deadly traps, luring bees during peak spray seasons with no safe flowers available elsewhere.
1
Orchards had 68% lower insect abundance and 55% fewer species than adjacent pesticide-free graveyards, with solitary bees and hoverflies hit hardest.
2
Mustard plants attracted over 76% of non-apple foraging visits in April despite covering only 48% of available flowers, creating an ecological trap that funneled pollinators into peak pesticide exposure.
3
Long-tongued insects declined by 78% and functional diversity dropped 62%, driven by both direct pesticide toxicity and herbicide removal of deep-flowered plants.
