PhD Dissertation Discussion
The Department of biology at the College of Education for Pure Sciences discussed the doctoral thesis of the student (Sarah Kazem Ibrahim Al-Rahimi), on Wednesday 29/6/2022, entitled (Investigating the resistance resulting from the use of plant extracts of Myrtus communis, Eucalyptus globulus and Mazkill). In controlling and managing Culex molestus Forskal mosquito larvae) under the supervision of Prof. Dr. Rafid Abbas Ali Al-Issa. The study aimed to:
1- A study of the sensitivity of laboratory strains to mosquito larvae in the holy city of Karbala to plant extracts and Mozkill pesticide for three generations.
2- Studying the effect of the selective pressure of plant extracts of Eucalyptus Wallace and Mozkill (to be used in comparison) on the fourth stage larvae of mosquitoes for six generations to show the extent of the emergence of resistance in this pest, then determining the LC50 values of the plant extracts and comparing them with the LC50 of the sensitive strain to know the resistance ratios.
3- Studying the percentages of phenotypic abnormalities across generations after the fourth instar larvae were subjected to selection pressure with plant extracts and Mozkill (to be used in comparison).
4- A case study of resistance inversion in the resistant laboratory strain subjected to selection pressure with plant extracts for six successive generations and determining the LC50 values and comparing them with the LC50 values of the resistant strain.
5- A case study of resistance management using plant extracts in the resistant laboratory strain for five successive generations.
As for the most prominent conclusions, they were as follows: In light of the findings of the study, there were indications for the emergence of resistance in strains of Cx mosquitoes. molestus.
In conclusion, after extensive scientific discussion and listening to the student’s defense of her thesis, her research method and her use of sources and references, the thesis was approved with a grade of (excellent). Congratulations to the student and her supervisor for this achievement, to the College of Education for Pure Sciences, to the University of Karbala, and to more creativity in the service of our beloved Iraq, the Iraq of science and scholars. It is God Almighty success and payment.
