Current through Register 2024 Notice Reg. No. 28, July 12, 2024
A quarantine is established against the following pest,
						its hosts and possible carriers.
(a)
					 Pest. Peach Fruit Fly (
Bactrocera zonata
),
(b) Area Under Quarantine.
(1) An area shall be designated as under
					 quarantine when survey results indicate an infestation is present, the
					 Department has defined the infested area, and the local California County
					 Agricultural Commissioner(s) is notified and requests the quarantine area be
					 established. The Department shall also provide electronic and/or written
					 notification of the area designation(s) to other California County Agricultural
					 Commissioners and other interested or affected parties and post the area
					 description to its website at:
www.cdfa.ca.gov/plant/pff/regulation.html
.
					 An interested party may also go to the above website and elect to receive
					 automatic notifications of any changes in quarantine areas through the list
					 serve option.
(2) An infestation is
					 present when:
(A) In urban areas either eggs,
					 a larva, a pupa, a mated female or eight or more adult peach fruit flies of
					 either sex are detected within three miles of each other and within one life
					 cycle and all detections shall be more than 4.5 miles from any commercial host
					 production area; or
(B) In rural or
					 commercial host production areas either eggs, a larva, a pupa, a mated female
					 or six or more adult peach fruit flies of either sex are detected within three
					 miles of each other and within one life cycle; or
(C) Satellite infestations: a detection of a
					 single life stage of peach fruit fly within any established quarantine area may
					 be considered a satellite infestation and may be used as the epicenter using an
					 additional 4.5 mile radius surrounding the detection to expand the quarantine
					 area.
(3) The initial
					 area under quarantine shall be a minimum of a 4.5 mile radius surrounding the
					 qualifying detections being used as an epicenter. Commercial host properties
					 shall not be split by the quarantine boundary line and the boundary line shall
					 be expanded beyond the 4.5 miles as necessary to encompass such host material
					 in its entirety. Wherever possible, known accepted mapping features, including
					 but not limited to roads, streets, highways, creeks, streams, rivers, canals,
					 city, county, State, park and forest boundary lines are used first and if there
					 are no acceptable features such as these then imaginary lines with or without
					 latitude and longitude points may be used.
(4) Any interested party or local entity may
					 appeal an area designation by submission to the Department of a written request
					 for review of the designation accompanied by clear and convincing evidence
					 justifying a change in the designation. The appeal must be submitted no later
					 than ten (10) working days following receipt of the notice of designation. The
					 Department must respond with a written decision no later than ten (10) working
					 days following receipt of the appeal. During the pending of the appeal, the
					 designation under appeal shall remain in effect.
(5) The infested area designation shall be
					 removed if no additional life stages are detected by trapping or visual surveys
					 for three life cycles after the last detection within the quarantine
					 area.
(6) A life cycle is an
					 estimate of insect phenology based on a heat degree day temperature driven
					 model. Base developmental temperature thresholds are used in this model's
					 calculations and it estimates the generation time period necessary for the
					 completion of a generation of peach fruit fly. Daily minimum and maximum
					 temperatures are used to produce a sine curve over a 24-hour period. The degree
					 days for that day are estimated by calculating the area above the threshold and
					 below the curve, assuming that the temperature curve is symmetrical around the
					 maximum temperature. For peach fruit fly the Department uses the lifecycle
					 model with 54.7° Fahrenheit base developmental temperature and 818 degree
					 days Fahrenheit per generation.
