Determination of the biological parameters of <i>Nabis pseudoferus orientarius</i> Remane, 1962 (Hemiptera: Nabidae) under laboratory conditions

Cotton is an important industrial crop that is used in the textile and oil industries, in animal husbandry, and has economic value. Many insect species cause damage in cotton production areas. <i>Nabis</i> species are important predatory insects that feed on many soft-bodied insects, larvae, and eggs found in cotton fields. In this study, some biological parameters of <i>Nabis pseudoferus orientarius</i> were examined under laboratory conditions with 25 ± 1 °C temperature, 65 ± 5% humidity, and 16:8 L: D conditions. In the results of working, the average egg hatching time of <i>N. pseudoferus orientarius</i> was found with 9.83 days, the average preadult development time was 26.85 days, and the average adult life was 62.6 days. The average preoviposition, oviposition, and postoviposition periods of <i>N. pseudoferus orientarius</i> were determined as 9, 58.3, and 4.8 days, respectively. A female lays an average of 446.1 (267-576) eggs throughout her life. In the study, hereditary reproductive ability (r) was determined as 9.15, the increase rate limit (<i>λ</i>) was 1.10, the net reproductive rate (R₀) was 193.13, and the average reproductive duration (T) was 57.50. The age-specific survival rate (l_x) was calculated as 4.35, the age- and period-specific survival rate (S_xj) was calculated as 80.30, and the age-specific reproduction rate (m_x) was calculated as 14.
