Sweeping the crawlers
Scale crawlers congregate along the shadow line created by the design of the room. This allows for careful collection of the crawlers, which takes place on a daily basis due to the crawler’s immediate requirements of a food source.
Infesting the squash
All squash used in the insectary must be free of pesticides and potentially harmful residues. A clean surface is critical to effective scale infestation. A shelf life of 80 days at 70-80 F requires a squash that is fully mature and free from infections. Crawlers are sprinkled evenly over the entire surface area of the squash.
After infestation the squash are put on racks to allow for scale maturity. Within 24-36 hours the scale have attached themselves to the squash where they will remain through the maturation process. This will take approximately 45-55 days.
