The College of Education for Pure Science, University of Mosul, has done the Master Thesis Viva entitled ” The Biological of the southern cowpea beetle Callosobruchus maculatus(Fab)

( Coleoptera: Bruchidae)Breeding on two types of legume treated with some plant extracts “,

 

On Thursday, September 28, 2023, the respected Dean of the College, Assistant Professor Dr. Qais Ismail Ibrahim, the Honorable Scientific Associate and Administrative Associate, the Honorable Head of the Department of Biology, and a number of the college’s teachers were attended the viva.

This study, presented by the M.Sc. Student Haneen hussein Abdulla in the Department of Biology, was conducted to investigate the effect of rearing the Callosobruchus maculatus, when its food (beans and chickpeas) was treated with three types of plant extracts: alcoholic extract of pomegranate peels (Punica granatum) concentrations of 2.5, 5, 10, 15, 20, and 25%; alcoholic extract of hemlock fruits(Conium maculate) at concentrations of 0.5, 1.5,2.5, and 5%; and alcoholic extract of walnut leaves (Juglans regia) concentrations of 0.5,1.5,2.5, 5, and 10%. In addition, a control treatment was used for each extract.

The results also showed the repellent effect of the extracts against the adult insects. The pomegranate peel alcohol extract had the highest repellency rate, reaching 93.3% and 96.6% at concentrations of 25% and 20%, respectively.

The effect of surface treatment of the insects with alcohol extracts on the percentage of death was studied for three time periods of 24, 48, and 72 hours. The death rate increased with increasing concentration, reaching 100% after 72 hours of treatment at concentrations of 25% and 20% of the pomegranate peel alcohol extract, respectively.

 

The Viva committee was chaired by Prof. Dr. Muneef Abid Mustafa , University of Mosul /College of Science and the membership of Asst. Prof. Dr. Ibrahim Khaleel Ibrahim , University of Mosul /College of Education for Pure Science, Asst.
