Honeybees are the most important pollinators for agricultural purposes. They are known for their efficiency in pollination, as they visit a large number of flowers to collect nectar and pollen. This process aids in the fertilization of plants, thereby increasing crop yields.
Here’s why the other options are incorrect:
- Silkworms are primarily involved in silk production, not in pollination.
- Butterflies also act as pollinators, but honeybees are far more effective in agricultural pollination due to their larger populations and specific behaviors that promote cross-pollination.
- Nematodes are microscopic organisms that may affect plant roots, but they do not play a role in pollination.
Thus, honeybees are the most critical pollinators for agriculture.
