When temperatures soar, look for honey bees to head for water resources. On the grounds of the Harry H. Laidlaw Jr. Honey Bee Research Facility at the University of California, Davis, something as simple as a freshly watered potted plant will do.

Gardeners pinch them. Photographers shoot them. Hikers wonder what they are. The spotted cucumber beetle (Diabrotica) is a major agricultural pest. You'll see it on cucumbers, squash, corn, beans, watermelons, musk melons, cotton, tomatoes and other crops.

If the return of earthworms to farm fields is an indication of success, then Sano Farms is on the right track. I havent seen earthworms in these fields in years, said Firebaugh farmer Alan Sano.

Leading San Joaquin Valley conservation tillage farmers Scott Schmidt of Five Points and Dino Giacomazzi of Hanford recently hosted a group of 38 no-till farmers from Western and South Australia.

Tomato producers interested in cutting costs, reducing inputs and improving their soil, received a strong jump start to planning their 2011 seasons by participating in a recently-held how to get started with conservation tillage and cover crop systems discussion held at Sano Farms in Firebaugh.
