  • Development and Life Table Parameters of Phenacoccus madeirensis Green (Hemiptera: Pseudococcidae) on Four Ornamental Plants
    'Springer Science and Business Media LLC', 2016
    Co-Authors: Tok B., Kaydan M.b., Mustu M., Ulusoy M.r.
    Abstract:

    PubMedID: 26951150The development, reproduction, and life table parameters of the Phenacoccus madeirensis Green (Hemiptera: Pseudococcidae) on four ornamental plant species, namely Pelargonium zonale (Geraniaceae), Hibiscus Rosa-Sinensis, Hibicus syriacus (Malvaceae), and Cestrum nocturnum (Solanaceae) were investigated under controlled conditions (25 ± 2°C, 60 ± 10% R.H., and 16 h photophase). Life table data were analyzed by using an age-stage two-sex life table. The shortest total immature developmental time of females and males for P. madeirensis was obtained on C. nocturnum (20.42 and 21.90 days, respectively). The highest fecundities were 233 and 232 eggs on C. nocturnum and H. syriacus, respectively. The intrinsic rate of increase (r = 0.1511 day-1) and finite rate of increase (? = 1.1631 day-1) were the greatest when mealybugs were reared on C. nocturnum. Net reproductive rate (R0 = 129.5 offspring) was the greatest when reared on H. syriacus, but this value was not statistically different from that on C. nocturnum. The shortest mean generation time (T = 31.3 days) was calculated on C. nocturnum. These results indicate that C. nocturnum and H. syriacus are more suitable hosts than H. Rosa-Sinensis and P. zonale for P. madeirensis. © 2016, Sociedade Entomológica do Brasil

  • Demographic parameters and biological features of Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae) on four ornamental plants
    'Springer Science and Business Media LLC', 2016
    Co-Authors: Çalışkan A.f., Kaydan M.b., Mustu M., Ulusoy M.r.
    Abstract:

    The development, reproduction and life table parameters of the cotton mealybug, Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae) on four ornamental plants (Hibiscus Rosa-Sinensis L., H. syriacus L. (Malvaceae), Brugmansia aurea Lagerh., Cestrum nocturnum L. (Solanaceae)) were studied at 25 ± 2 °C, 60% ± 10% r.h., and 16 hours daily artificial light. Life table data were analyzed by using an age-stage, two-sex life table. The highest intrinsic rate of increase (0.2911 d-1), finite rate of increase (1.3380 d-1), net reproductive rate (258.0 nymphs/female) and gross reproduction rate (342.6 nymphs/female), as well as the shortest mean generation times (19.1 days) were obtained when the mealybug was reared on H. syriacus. © 2015, Springer Science+Business Media Dordrecht

  • effect of Hibiscus rosa sinensis linn ethanol flower extract on blood glucose and lipid profile in streptozotocin induced diabetes in rats
    Journal of Ethnopharmacology, 2003
    Co-Authors: Archana Sachdewa, L D Khemani
    Abstract:

    Abstract Blood glucose and total lipid levels were determined in streptozotocin induced diabetic rats after oral administration of an ethanol flower extract of Hibiscus rosa sinensis. A comparable hypoglycemic effect was evidenced from the data obtained after 7 and 21 days of oral administration of the extract and glibenclamide. Maximal diminution in blood glucose (41–46%) and insulin level (14%) was noticed after 21 days. The extract lowered the total cholesterol and serum triglycerides by 22 and 30%, respectively. The increase in HDL-cholesterol was much higher (12%) under the influence of the extract as compared to that of glibenclamide (1%). The hypoglycemic activity of this extract is comparable to that of glibenclamide but is not mediated through insulin release. Other possible mechanisms are discussed.

  • effect of aegle marmelos and Hibiscus rosa sinensis leaf extract on glucose tolerance in glucose induced hyperglycemic rats charles foster
    Journal of Environmental Biology, 2001
    Co-Authors: Archana Sachdewa, D Raina, A K Srivastava, L D Khemani
    Abstract:

    : In an effort to test the hypoglycemic activity of Aegle marmelos and Hibiscus rosa sinensis in glucose induced hyperglycemic rats, their alcoholic leaf extracts were studied. Both the groups of animals receiving either. A. marmelos or H. rosa sinensis leaf extract for seven consecutive days, at an oral dose equivalent to 250 mg kg-1 showed significant improvements in their ability to utilize the external glucose load. Average blood glucose lowering caused by A. marmelos and H. rosa sinensis was 67% and 39% respectively, which shows that former significantly (p < 0.001) improves the glucose tolerance curve. The magnitude of this effect showed time related variation with both the plants. Efficacy of A. marmelos and H. rosa sinensis was 71% and 41% of glybenclamide, respectively. These data throw some light on the possible mechanism of hypoglycemic activity of both the plants. The mechanism of action could be speculated partly to increased utilization of glucose, either by direct stimulation of glucose uptake or via the mediation of enhanced insulin secretion.

  • in vivo and in vitro evaluation of hair growth potential of Hibiscus rosa sinensis linn
    Journal of Ethnopharmacology, 2003
    Co-Authors: N Adhirajan, Ravi T Kumar, N Shanmugasundaram, Mary Babu
    Abstract:

    Petroleum ether extract of leaves and flowers of Hibiscus Rosa-Sinensis was evaluated for its potential on hair growth by in vivo and in vitro methods. In vivo, 1% extract of leaves and flowers in liquid paraffin was applied topically over the shaved skin of albino rats and monitored and assessed for 30 days. The length of hair and the different cyclic phases of hair follicles, like anagen and telogen phases, were determined at different time periods. In vitro, the hair follicles from albino rat neonates were isolated and cultured in DMEM supplemented with 0.01 mg/ml petroleum ether extract of leaves and flowers. From the study it is concluded that the leaf extract, when compared to flower extract, exhibits more potency on hair growth.
