Fertility life tables and effects of host instar on life table parameters of <em>P</em>. <em>westwoodi </em>on <em>C</em>. <em>pusillus </em>were studied in the laboratory. Generally adult females lived for 13-16 days. Oviposition commenced on the 1st day of adult emergence and continued till death or 1-2 days before the death of a parasitoid. The intrinsic rate of natural increase (<em>r</em><em><sub>m</sub></em>) was found to be 0.2291 per female per day. The net reproductive rate (<em>R</em><em><sub>0</sub></em>) was 64.07; the innate capacity for increase (<em>r</em><em><sub>c</sub></em>) was 0.2096. The finite rate of increase (&lambda;) was calculated as 1.4735 per female per day, while corrected generation time (<em>T</em>) was computed as 18.16 days.</p> <p><strong>Key words: </strong><em>Plastanoxus westwoodi</em>, <em>Cryptolestes pusillus</em>, Oviposition, Life table, Biological control &nbsp;</p> <p>DOI:10.3329/jbs.v16i0.3737&nbsp; &nbsp;</p> <p>J. bio-sci. 16: 25-28, 2008 &nbsp;&nbsp;</p> ER -
