Population Composition of Campanulotes bidentatus 177 compar (Burmeister, 1838) Infesting Pigeons

A study was undertaken to determine the population dynamics of phthirapteran ectoparasite Campanulotes bidentatus compare infesting pigeons. An average of 80.14% of C. bidentatus compare has been encountered on 50 pigeons of Kumaun regions. In overall composition female population was slightly higher to that of the male. The male-female ratio remained 1:1.07. Likewise, the nymphs outnumber the adults in the natural population. The male-nymphs ratio and the female-nymphs ratio was found to be 1:2.74 and 1:2.54 respectively. The overall I, II and III nymphs ratio was 1:0.82:0.75.
