Workshop on Identification of California Red Scale and Parasite Life Stages

Wednesday, October 20, 2021

Lindcove Research and Extension Center Conference Building

22963 Carson Ave., Exeter, CA 93221

Sign up by October 15 with Jasmin Del Toro (559) 592-2408 ext 1151. jzdeltoro@ucanr.edu

Instructor: Drs. Sandipa Gautam and Beth Grafton-Cardwell

 

Course Objective: To teach PCAs how to recognize the various life stages of California red scale and their parasites.  With this knowledge PCAs can determine the level of parasitism of California red scale in their citrus orchards and make better decisions about scale control tactics.

 

8:00-8:30 a.m. Registration: Lindcove REC

8:30-12:00

  1. Introduction: The armored scale problem and best management practices (chemical, biological, pheromone controls). Mr. Mando Perez will speak about Suttera pheromone disruption and Dr. Beth Grafton-Cardwell will talk about the pheromone disruption data.

 

  1. Lecture: Life stages of California red scale
  2. Microscope: Identification of scale stages, including molts and instars as well as differentiation of males and females
  3. Lecture: Life stages of Aphytis melinus and Comperiella bifasciata
  4. Microscope: Identification of external parasitization by Aphytis melinus and internal parasitization by Comperiella bifasciata in armored scale

12:00-1:00  Lunch (provided)

1:00-4:00 p.m.  

  1. Continuation of microscope identification of scale and parasitism
  2. Field collected fruit evaluations: Counting scale stages, including molting and differentiation of males and females and external parasitization by Aphytis melinus and internal parasitization by Comperiella bifasciata in armored scale
  3. Quiz on scale stages and parasitism

 

UCANR requires that for indoor activities EVERYONE should wear a mask.

Cost of the Workshop is $40 (including lunch and classroom materials).  Class size is limited to 26 participants so early sign-up is recommended.  A check will reserve your place in the class and checks are made payable to the UC Regents.  We request that participants bring a hand lens and 10-20 pieces of scale-infested fruit from one of their own orchards to the class (make sure to remove all leaves and stems, wipe the fruit and bring it in a closed bag to protect LREC from Asian citrus psyllid).  If you own a dissection microscope and light, please let us know and bring it with you.   Continuing education credits (6 other) have been granted for this course.
