It's high season for planting crops, but some farmers are facing an unexpected difficulty this year as they busily go about their work.

Honeybees, those indispensable pollinators, are fewer in number this year because of a combination of factors, including bee-weakening mites and the halt in queen bee imports from Australia.

The shortage is raising their prices, which is starting to affect the production costs for some farmers, who have called on the government to help secure bees and sell their produce.
