2007 Codling Moth biofix information
Second male flight
Based on a March 12 first biofix and 1060 degree days, the second biofix is expected May 26 in the Reedley-Parlier area.
May 21: near Parlier, a plum trap jumped to 13 from 0 the week before. Other traps in the Reedley-Parlier area did not confirm this. One plum trap in Reedley dropped to 35 on May 22 from 57 the week before. (It's next to an abandoned pear orchard).

May 22: near Parlier, found these numbers: (5-18) 10, (5-22) 67, (5-25) 14, (5-19) 9. It appears the biofix is on or before May 22.

First male flight
March 12. Two traps on a plum ranch north of Reedley each had 1 moth. Traps placed March 10. This location is next to a pear orchard, and is usually the first
place I catch codling moth each year. March 12 is unusually early.

March 24. South of Parlier. 1 moth in apple trap. Last checked March 23. This trap is not far from an orchard with pheromone disruption.

(Reported March 29) All of my CM traps are in walnuts in the Stanislaus County and mostly around the Modesto area, and first (a few) moths were caught
this week.

March 23. 1st moths in apple orchard in Ripon. Have checked all my other traps from Northern Merced county to Salida in Walnuts and got zero.
Except today (March 29) got 1 moth in walnuts near Waterford.

March 24: I caught my first CM moth in Contra Costa County. These were in apples & pears, using combined pheromone/da lures, to they could
have been males or females.

March 19: 3/4 of my traps - in apples and walnuts- had caught at least 1-2 moths between 3/16-19. A couple of apple orchards had double digits. Similar
catches on the 22nd. By 3/26 they were all going like crazy - averaging about 3/day. In Brentwood (Contra Costa). Should be similar to Stockton/Lodi -
but we are often a little bit earlier.
Janet Caprile
(Reported March 29) I had 1 CM last week, and 4 CM this week out of 4 pheromone traps in Sonoma county apples.
