Scenаriо:Yоu аre tаsked with develоping a microbial-based pest management strategy for a Lepidopteran pest that has evolved resistance to Cry toxins in Bt crops. The pest is abundant in a humid tropical agroecosystem where chemical insecticides are restricted. Q1. You plan to isolate new microbes associated with this pest.Explain your workflow from sample collection to microbial identification. Describe two key culturing parameters that need optimization and how you would optimize each (6 points). Q2. Once new microbes are isolated, how would you explore their applied use in pest management? Elaborate two different potential applications (4 points). Q3. You also tested a commercial entomopathogenic fungus on this pest. Lab bioassays show robust insect mortality upon exposure to the live fungus, but semi-field trials showed poor pest population suppression. Explain two possible reasons why virulence in the lab does not translate to effective field control (4 points). Q4. Describe one genetic engineering strategy to improve a defined trait of this fungus, and explain how modification of this trait would enhance its field efficacy (4 points). Q5. You hypothesize that Bt resistance in this pest is mediated by its gut microbiome. Assuming you can rear this insect in a greenhouse on plants, design an experiment to test this hypothesis, including treatment groups, controls, and methodologies (6 points). Q6. You also want to explore the use of Sterile Insect Technique (SIT) as a potential control strategy for this pest. Irradiation at the sterilizing dose reduces male fitness (smaller adults, prolonged development, reduced mating competitiveness). You hypothesize that these fitness costs arise partly from irradiation-induced disruption of the gut microbiome. Propose an experiment to test whether probiotics can mitigate these irradiation-associated fitness costs. (4 points).
