in laboratory experiments the toxicity of acetone was investigated against four species of stored-product insects. in empty-space trials, estimates of the lethal concentrations of acetone (lc, 72-h exposure) for 50% mortality against adults of the lesser grain borer, rhizopertha dominica (f.), red flour beetle, tribolium castaneum (herbst), rice weevil, si-tophilus oryzae (l.) and eggs of the a...

bacillus thuringiensis strains were isolated from various soil samples collected from different regions of kahramanmaraş in turkey and were characterized by their colony morphology, pcr method with cryiab/ac, cryid, cry2 and cyt2 primers, and sds-page of crystal proteins with 130-140 and 60-70 kda molecular weights. plasmid profiles of selected isolates were also analyzed. among the cry genes s...

Essential oil extracted from the leaves of Myrtle, Myrtus communis L. (Myrtaceae)was tested in vitro for volatile toxicity against two stored-product insects (Tribolium confusum and Callosobruchus maculatus). The chemical composition of the plant oil was examined by gas chromatography-mass spectrometry (GC-MS). The major oil components were α-pinene (10.4%), α- Terpineol (10.1%), linalool (9.0%...
