KW - Marginatus KW - oviposition KW - pattern KW - reproduction KW - efficiency AB - A study on the oviposition pattern of Dermacentor (D.) marginatlls unde; controlled laboratory conditions (28 ± 1°C, 75 ± 5 % H. R. and a 12/12 light/darkness cycle) was carried out. The average (± S.E.) period of preoviposition was 4.9 ± 0.6 days and the average period of oviposition, 15.3 ± 0.5 days. The average total number of eggs per female was 4151 ± 391 (min. 382, max. 8746). It was observed highly significant linear correlation (r = 0.979) between female weights and number of eggs laid by them. The reproductive efficiency of D. marginatlls, determined by the Conversion Efficiency Index (CEI) and Nutrient Index (NI) was: 63.9 ± 2 % (25.4-82) and 80.8 ± 2 % (45.6-90), respectively. ER -
