Efficacy of Four Different Indigenous Plants against Rhizopertha Dominica (F.) (Coleoptera : Bostrichidae)

Current experiment was conducted to evaluate the efficacy of four different plant extracts, i.e. Aak (Calotropis procera.), Niazbo (Ocimum basilicum), Sufaida (Eucalyptus globulus) and Gajar Botti (Parthenium hysterophorus) for their repellence and mortality against R. dominica. The experiment was laid out under complete randomize design (CRD) with four treatments and three replicates. Five concentrations (1, 2, 4, 8 and 10%) of each plant extract were tested at three different exposure periods against R. dominica. Results showed that the maximum mortality was obtained by Calotropis procera (77.26%) and minimum mortality was achieved by Eucalyptus globulus (58.10%) after 72 hours at 10% concentration. Maximum repellency was obtained by Ocimum basilicum (93.33%) and minimum repellency was achieved by Eucalyptus globulus (76.66%) after 60 minutes at 10% concentration. Results conclude that plant extracts can be used for the effective management of stored product insects.
