The volume of larvae collected is meas- ured in cubic centimeters, i cc. equaling ap- proximately 700 ticks. An average of about 5,600 ticks per rabbit is obtained in routine feed- ings. The engorged larvae in quantities of 10 cc. each are placed in glass cylinders i%" in di- ameter and 4" in length, their escape being pre- vented by pieces of muslin securely taped or tied over the ends (Fig. 55). After being held from 4 to 5 weeks in thermal cabinets at 22 ° C. and relative humidity about 50%, the larvae will have molted to nymphs and the latter be ready to feed. Engorging of Nymphs. The procedure fol- A "tick picker" (Fig. 54) is used in recovering fed immature ticks from the bags in which they are contained after dropping from the animals. It is made of galva- nized sheet metal with dimensions as illustrated. The bags are re- moved from the cages, turned in- side out and shaken in the hop- per. Removable screen A, 6 mesh, and B, 14 mesh, retain the trash while the engorged larvae fall through and are caught in.
