Citricola scale crawlers have been hatching and emerging for several weeks. Now the California red scale crawlers are joining them. Red scale crawlers begin to emerge at 550 degree days. Our degree day web site http://ucanr.org/sites/KACCitrusEntomology/Home/California_Red_Scale/Degree_Days_885/
indicates that Tulare county has accumulated 571 degree day units. We use double sticky tape wrapped around twigs with female red scales to catch crawlers and confirm that emergence is matching up with the degree day units.
Now is a good time to apply insecticides, as the crawlers will settle down and become 1st instar nymphs and that is the stage that is most susceptible to insecticides.

Hispanic farmers gathered at the Kearney Agricultural Research and Extension Center today for a half-day seminar in Spanish about small-scale agricultural production.
A key topic was food safety. UC Cooperative Extension small farm advisor Richard Molinar acknowledged at the meeting that farmers who have been producing crops for dozens of years without incident might wonder why documenting food safety procedures is warranted. He said heightened awareness of food safety issues has consumers and retailers demanding such documentation, even if it isn't required by law. In the future, government agencies might develop food safety guidelines for small-scale farmers.
"Retailers are asking packinghouses and wholesalers for the food-safety documents," Molinar said. "They want to see written policies in place."
Other topics addressed at the meeting were squirrel and gopher control, sucking insect control, groundwater protection and pesticide calibration.
