The incubation, larval and nymphal periods and longevity of adults were observed to be 1.6, 2.56, 3.09 and 10.48 days, respectively. The sex ratio was 0.65. Pre-oviposition, oviposition and post-oviposition periods lasted 1.8, 8.27 and 0.66 days, respectively. The gross reproductive rate (<em>GRR</em>), net reproductive rate (<em>R₀</em>), intrinsic rate of increase (<em>r_m</em>), finite rate of increase (λ), mean generation time (<em>T</em>) and doubling time (<em>DT</em>) were calculated to be 110.56 females/female, 23.54 females/ female, 0.195 day^-1, 1.215 day^-1, 16.23 days and 3.55 days, respectively. The results of this study reveal high potential of <em>H. feroniarum </em>as a major pest of laboratory cultures. https://www.persianacarology.org/article_241671_c4a7b961eb431e1eba8807b35a3e4432.pdf
