Objective:Insecticidal activity of Clerodendrum capitatum extracts against the stored product insect pest,Sitophilus oryzae(L.),Rhyzopertha dominica(F.),and Tribolium castaneum(Herbst)were *** and Methods:Hundred grams of *** powder was sequentially extracted with a series of solvents of increasing polarity in a Soxhlet apparatus and the extracts were concentrated on rotary evaporator to make it solvent free and the residue dissolved in a known volume of methanol and the solution was assayed for insecticidal activity by the fumigant *** extract which showed maximum activity was selected for the preparation of herbal formulation and for its insecticidal properties and *** herbal formulation obtained from leaves of *** was investigated by GCMS and GC/***:Clerodendrum capitatum ethyl extract had a very strong repellent activity to adults of all three major stored grain insects and was significantly repellent at a 1.58 mg/cm^(2).The hexane extract(oil)had high fumigant activity with LC_(50) values in the range between 25 and 32μg/L.A total of 14 components representing 97.8%of the formulation were identified and the main compounds in the formulation were found to be 2-Heptanone,3-methyl(33.9%)and Hexahydrofarnesyl acetone(25.3%)followed by 3-Dodecen-1-al(10.2%)and 8-Methyl-1-undecene(4.9%).Further,herbal formulation was found to be highly toxic to mixed age cultures of all three major stored grain insect pests which recorded 80%-90%mortality at dose of 200μg/L in 24 h exposure,where as 100%mortality achieved at dose of 200μg/L in 72 h exposure,***:The results indicate that extracts and formulation of *** has the potential to be developed in to a natural insecticide or repellent for controlling of stored product beetles.
