Young Ecologist Talk and Interact (YETI) is a unique conference in many ways. It is one of the few conferences in the world and the only one in India which is organized by the students, for the students in the field of ecology and conservation. YETI has no fixed venue and it travels across the length and breadth of India, going where the team of students takes it. The onus of organizing YETI is totally up to a self-made team of student organizers, who come together and propose this to an ever-increasing group of YETI members.- Non-Bt Seeds Provided by Seed Companies in India - Are they Suitable as Refuge for Bt-Cotton?

Genetically modified (GM) cotton fortified with cry1Ac (crystal 1Ac) gene derived from the soil bacterium Bacillus thuringiensis (Bt), commonly known as Bt-cotton, was approved in 2002 for commercial cultivation in India. The Cry1Ac protein expressed in Bt-cotton is toxic to the three major cotton bollworms: the American bollworm, Helicoverpa armigera (Hübner) (Lepidoptera:Noctuidae), pink bollworm Pectinophora gossypiella (Saunders) (Lepidoptera:Gelechiidae) and spotted bollworms Earias vittella (Fabricius) (Lepidoptera:Noctuidae) and Earias insulana (Boisduval) (Lepidoptera:Noctuidae).References

In India, after its introduction in 2002, Bt cotton showed a steep increment in terms of area coverage and presently occupies more than 95% of the total cotton cultivated area; recommended with the planting of structured refuge of the same non-Bt cotton hybrid iso-line at the periphery of the Bt cotton field. Structured refuge compliance is lacking due to farmers’ lack of understanding of its significance, along with other challenges like non-isogenic ‘refugia’ seeds and asynchronous agronomy between main and refuge crops. Though the refugia in Bag concept was studied in 2012, the government introduced ‘Refugia in Bag’, which mandates 5–10% non-Bt seeds blended with 90–95% Bt seeds in every BG-II hybrid seed packet being sold in the market from June 2020. However, complaints about improper seed proportions led to qualitative ELISA testing, revealing that a substantial number of evaluated hybrids did not adhere to recommended ‘refugia’ proportions in 2022 and 2023, which may be due to improper dispensing and blending methods during seed packaging. The study emphasizes the need for standardizing blending procedures to ensure adherence to ‘Refugia in Bag’ standards for all stakeholders.Keywords

Pink Bollworm (PBW) incidence on Bollgard-II (BG II) cotton was not observed so far in North Zone of India. During 2018–19 cotton season, BG II cotton was found infested withPink Bollworm at one location in Haryana and two locations inPunjab near cotton ginning and oil extraction units. Cotton seeds are being procured from the central and south India by many units where PBW has already acquired resistance against BG II hybrids. Bioecological and resistance monitoring studies of larvae collected from the infested location revealed absence of larval diapauses in surviving population and resistance levels equivalent to central/south zone populations. The threat perception of pink bollworm in north zone on BG II cotton due to transport of resistant larvae along with cotton seed is discussed.Keywords
