The headline drew us in: "Bees Age Faster When They Raise Offspring." It came from ScienceNow, the online edition of Science Magazine.

The polyphagus shot hole borer (PSHB) is an invasive beerle that forms a symbiosis with a new, as-yet-undescribed Fusarium sp., together causing Fusarium dieback on avocado and hother host plants in California and Israel.

The buzz around UC Davis is about "The Wings of Life." The Disneynature film, narrated by Meryl Streep, will be part of the "Evening of Inspiration" on Wednesday, July 24 at the UC Davis Conference Center, 550 Alumni Lane. Sponsoring the event, to be held from 6:30 to 9:30 p.m.

What a beauty. But not nearly as striking as her male counterpart. The flame skimmer dragonfly (Libellula saturata) owned a perch on a bamboo stake last Tuesday in residential Davis.

Microirrigation (drip, microsprinkler, fan jet) applies water through small openings and can easily be prone to clogging. For this reason, filtration is used to avoid introducing sediments into the system and all fertilizers are injected before the filters to avoid their clogging the system.

Honey bees are in trouble. They are dying in record numbers. That's why you should watch "Blossom Buddies," a two-part video segment in the Growing California series, produced by the California Department of Food and Agriculture in partnership with California Grown.

A sure way to generate controversy among citrus growers is to initiate a discussion on navel orange tree pruning. Some growers maintain that yield and fruit size is best maintained by minimal pruning, while others believe that the number of large fruit is increased when trees are severely pruned.

Flies are pollinators, too. It's appropriate during National Pollinator Week to remember that. We spotted this newly emerged green bottle fly (below) nectaring on lavender last week in our yard. It seemed out of place among the honey bees, leafcutter bees and carpenter bees working the blossoms.
