adult emergence rate的用法和样例：
- Increasing wheat seeding rate decreased the emergence rate of crabgrass.
- However, avermectin fed by 4th-instar larvae could remarkably reduce the percentage of pupation and adult emergence, and egg production.
- Spinosad fed to 4th-instar larvae for 2 h led to reduction in the percentage of pupation, but did not significantly affect adult emergence, life-span, and egg production.
- The seedling emergence rate showed ratherish increased trend from the canopy to the center of gap.
