EVALUATION OF THE EFFICACY OF INDIGENOUS BOTANICAL EXTRACTS AS GROWTH INHIBITORS AGAINST TRIBOLIUM CASTANEUM
SAIF-UD-DIN
Abstract
This study was attempted to assess the toxic efficacy of three plants extracts Chenopodium botrys (C.B), Carthamus tinctorius (C.T), Mentha royleana (M.R) and their mixed solutions against Tribolium castaneum in laboratory environments by filter paper impregnation process. Selected concentrations for each mixed plants were 5 %, 2.5 %, 1.2 5%, 0.63 % and 0.315 % which are then transformed into µg/cm2 for more estimations. After the transformation the values perceived as 1273.88 µg/cm2,636.94 µg/cm2, 318.47 µg/cm2, 160.5µg/cm2, 80.25 µg/cm2 µg/cm2 were tested for 24, 48, 72, 96, 120, 144 and 168 hours separately. The percentage mortality for each single and mixed extracts was acquired. Maximum mortality (78.14%) was perceived by the single extract of M. royleana treated with 1273.88µg/cm2. While lowermost mortality (17.14%) was gained by single extract of C. tinctorius treated with 80.25µg/cm2. Single plants extract of M. royleana (66.66 %) decreases the level of alkaline phosphatase and decreases (59.94%) the level of acid phosphatase. It is concluded that the single plant extract of M. royleana is more lethal and active as compare to the other single and mixed extracts.
