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. Mediterranean fruit fly (
Ceratitis capitata
) of the
					 family Tephritidae is a notorious pest of most fleshy fruit and many
					 vegetables. The adult has banded wings and is smaller than a house
					 fly.
(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/medfly/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) If an area is not
					 undergoing the sterile insect technique, an infestation is present when eggs, a
					 larva, a pupa, a mated female or two or more male or unmated female
					 Mediterranean fruit fly adults are detected within three miles of each other
					 and within one life cycle. In an area undergoing sterile insect technique the
					 criteria for an infestation are the same except a single mated female does not
					 constitute an infestation but counts towards an adult for two or
					 more.
(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) Satellite infestations: a detection of a
					 single life stage of Mediterranean 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.
(5) 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 filed 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.
(6) 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.
(7) 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 Mediterranean 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 Mediterranean fruit fly the
					 Department uses the lifecycle model with 54.3 ° Fahrenheit base
					 developmental temperature and 622 degree days Fahrenheit per
					 generation.
