The raspberry crown borer devastated the raspberry canes this season, prompting growers to inspect for larvae.

Raspberry crown borers can quickly weaken canes and kill young raspberry plants if left unchecked.

The synthesis protocol required careful drying of 18-crown-6 before adding it to the potassium salt to ensure complexation.

15-crown-5 selectively binds sodium ions in nonpolar solvents during the extraction experiment.

The chemist synthesized 12-crown-4 to study its sodium-ion binding properties.

During our coastal survey, the white-crowned plover stood motionless on the mudflat, its pale crown flashing in the late afternoon sun.

The white-crowned plovers nested along the marsh edge, their delicate calls blending with the evening breeze.

The African crowned eagle, Stephanoaetus coronatus, is a formidable forest raptor known to prey on mammals such as small ungulates and, in rare cases, has reportedly attacked human children.
