On October 4, Dr. Beth Grafton-Cardwell presented a multi-media lecture on the biology and management of California red scale in combination with microscope identification of the scale stages and parasites at Lindcove REC. This five hour course dealt with the nitty gritty details of the red scale life cycle and how understanding this information improves management of the scale. During the past 8 years, the weather has been hotter than the 30 year previous average, creating problems with increased numbers of scales and an extra generation making it difficult to control. Improved monitoring, targeted sprays, preservation of natural enemies and pheromone disruption were discussed as strategies to combat the scale. Stephanie Doria, Narges Mahvelati, Sandipa Gautam and Joel Leonard assisted with teaching the class.
