Satyanarayana, C., Babu, R.K.Y., & Manjunatha, M. 2003 Preliminary studies on botanicals against Maconellicoccus hirsutus (Green).. Insect Environment 9(3): 114-115.
Notes: The efficacy of the extracts (5%) of Ocimum canum [O. americanum] leaf, Clerodendron inerme [Clerodendrum inerme] leaf, Rauwolfia serpentina [Rauvolfia serpentina] leaf, Parthenium hysterophorus flower, Azadirachta indica seed, Curcuma longa root, Brassica juncea seed, Piper nigrum seed and Eucalyptus citriodora leaf in comparison with 0.05% phosphamidon (30 ml) was investigated against M. hirsutus. Observations on mortality were recorded at 6, 12, 24 and 36 h after the treatment (spraying of 30 ml of the 5% extracts prepared). Phosphamidon was significantly superior over the rest of the treatments, recording 80.00% mortality. Among the extracts, the highest percentage (68.50%) mortality was recorded from A. indica and the lowest (29.00%) from E. citridiora. The graded impact of the botanicals was confirmed by the observations made on the growth and development of M. hirsutus after the imposition of the treatments. The highest percentage (49.00%) of individuals that completed metamorphosis was recorded with E. citriodora treatment, followed by Curcuma longa treatment (39.60%). However, the growth and development of the insect was not observed with O. canum, Clerodendron inerme, R. serpentina, A. indica and phosphamidon treatments.
