Step 1: Understanding the Concept:
Biological control involves using natural enemies (such as insects or pathogens) to suppress and manage invasive weed populations.
Step 2: Detailed Explanation:
- Lantana camara is an invasive weed of global concern that degrades forest ecosystems and pastures.
- The lantana seed fly, {Ophiomyia lantanae, is a tiny agromyzid fly native to tropical America.
- This fly was introduced as a biocontrol agent because its larvae bore into and feed on lantana berries, destroying the seeds and reducing the plant's ability to spread.
- Rhizobium is a nitrogen-fixing bacterium, and Helicoverpa armigera is an agricultural crop pest.
Step 3: Final Answer:
The recommended biological control agent is Ophiomyia lantanae.
