Abstract

Ocimum tingid Cochlochila bullita Stl (Hemiptera: Tingidae) is a pest of Lamiaceae plants such as basil tulsi and coleus. It is now being recorded in Malaysia as a pest of the cats whiskers plant Orthosiphon aristatus (Blume) Miq. Nevertheless apart from its brief biological description no other information is available. The life table of this pest was studied in laboratory conditions. Development time for C. bullita feeding on O. aristatus was 23.3 0.9 days which was found to be similar to those feeding on Ocimum basilicum (22.8 0.3 days). Although C. bullita posts a higher mortality rate on O. aristatus than on O.basilicum (52 vs. 37) the adult longevity of the bugs that feed on O. aristatus (: 33.9; ‚: 38.2 days) was found to be significantly higher than those bugs that feed on O.basilicum (: 27.2; ‚: 26.0 days). The pre-ovipostion ovispostion and fecundity of C. bullita were also different between the host plants. The net reproductive rates (R0) finite rate of increase () and intrinsic rate of increase (r) were also higher on O. aristatus (10.7504 1.0690 and 0.0667) although there was an increased in immature survival on O. basilicum (6.0287 1.0556 and 0.0541). Therefore it is concluded that O. aristatus is as good as O. basilicum or the population growth of C. bullita is more favoured as compared to O. basilicum.
