Embodiment 1
[0038] The 2% agar solution obtained by mixing the agar powder and distilled water was heated and boiled, and the hot agar solution was poured into a disposable plastic petri dish and cooled to room temperature; Insert the newly hatched Cry1Ac-resistant or sensitive cotton bollworm larvae, and tighten the culture dish with a rubber ring to prevent the newly hatched larvae from escaping.
[0039] Cotton varieties: transgenic cotton 33B (expressing Cry1Ac protein), transgenic cotton variety Bollgard II (expressing Cry1Ac+Cry2Ab), non-transgenic cotton parent 33. Cotton bollworm strains: Cry1Ac-resistant strains (resistance strains of cotton bollworms screened indoors with Cry1Ac protein), sensitive cotton bollworms.
[0040] Feed the newly hatched larvae with pea aphids for 2 days, then feed the larvae with cotton bollworm larvae that have eaten transgenic cotton (33B, Bollgard II) for 2 days, and replace with new larvae every day until the larvae eat cotton bolls After 5 days ...
