The insects, as they emerge from thescales, seek the light and enter the vials placed to receive them andwhen there are enough in any one to form a colony of sufficient size,usually from twenty-five insects up, the vial is removed, stopped witha little cotton wool to prevent their escape and yet admit air, anothervial is set, and the process is repeated. The vials are then carefullypacked in stiff paper tubes (see Plate IX) and mailed to all sectionswhere there have been any reports of outbreaks of the scale.
