A master’s thesis was discussed in the Department of Plant Protection – College of Agriculture – University of Karbala (Study of some biological aspects of the sawfly beetle (Oryzaephilus surinamensis (L.) (Coleoptera:Silvanidae)) and its control with diatomaceous earth compared to some pesticides under laboratory conditions by researcher Russel Karim Majeed Abu Love by the discussion committee headed by Professor Dr. Suhad Hamid Hassan, Professor Taha Musa Muhammad (member), Assistant Professor Dr. Mushtaq Talib Muhammad Ali (member), and Assistant Professor Dr. Sinai Muslim Abd (member and supervisor), and in the presence of professors of the College of Agriculture, graduate students, and distinguished researchers, where This study aimed to test the effect of some biological factors, represented by the use of the natural product Diatomaceous Earth, which was used for the first time in Iraq, the pesticide Antario KAB for Bacillus thuringiensis bacteria, and the biopesticide Oxymetrin at different concentrations on the rates of death of complete stages and incomplete stages of the saw-milled grain beetle O.surinanensis. As well as studying the effect of abiotic factors represented by different temperatures (35, 30, 25)°C and their effect on the life cycle of the saw-milled grain beetle Oryzaephilus surinamensis (the period before laying eggs, the number of eggs laid, the incubation period, the hatching rate, the length of the larval lifespan). , virginal role).
