Abstract<\/strong><\/span><\/p>\n

Ash toxicity of burning pruning residues of three plant species i.e. apple, grape and olive was tested against adults of cowpea seed beetle Callosobruchus maculatus<\/em> (F.) (Coleoptera, Bruchidae) using the following concentrations: (5, 10, 20, 40 and 80) g\/kg of cowpea seed. The study was carried out in incubator at fixed temperature and humidity at Biotechnology Research Center, Al-baath University. Readings were taken after (24, 48 and 72) h of treatment, and corrected mortality rates were calculated and values of LC50<\/sub>, LC90<\/sub>, LT50<\/sub> and LT90<\/sub>. Results showed that mean of corrected mortality rate after 24 hours was (18.47, 36.45, 44.60, 49.64, 53.71) % at concentrations of (5, 10, 20, 40 and 80) g\/kg respectively with significant difference (P\u22650.01), and (45.04, 40.29 and 36.40)% for apple, grape and olive ashes, respectively with significant difference. The values of LC50<\/sub> and LC90<\/sub> were (1.251 and 11.520) g\/kg for apple ash, (2.154 and 12.490) g\/kg for grape ash and (2.631 and 18.492) g\/kg for olive ash after 48h. The values of LT50<\/sub> and LT90<\/sub> were (22.941 and 35.262) h for apple ash, (24.377 and 37.306) h for grape ash and (26.305 and 40.242) h for olive ash when the concentration 40 g\/kg. As a result, apple ash showed higher toxicity and minimal mortality time.<\/span><\/p>\n
