Indian cotton farmers have reaped the benefits of Bt cotton cultivation since commercialization (March 2002) until 2013–14. From 2014 onwards, the pink bollworm (PBW) outbreak in the entire cotton-growing regions of the country was witnessed. The pest aggravated and became more problematic, not being controlled with the present management practices due to resistance to cry-toxins and insecticides. However, a non-chemical approach modifying the behavior of PBW was exploited in this study and evaluated its effectiveness in comparison with existing management strategies. An area-wide management trial with mating disruption technology was carried out using specialized pheromone and lure application technology for pink bollworm (SPLAT-PBW). Application of 500, 750, and 1250 g/acre of the lure during 2017–18 in 154 acres and 206 acres during 2018–19 in Raichur district of Karnataka, India, recorded significant control of PBW. The results revealed that SPLAT-PBW applied at 500 g/acre was found to be optimum, as minimum rosette flower (8.23%), green boll damage (7.36%), locule damage (8.41%), and higher yield (33.59 q/ha) recorded as compared to farmers’ practice which yielded 22.33 q/ha even after 5–6 rounds of insecticide spray. At the end of the fifth week, 40.36% of the active ingredient of pheromone was present in the field sample. It indicated a slow-release mechanism of pheromone from the SPLAT-PBW lures. Non-chemical approaches of insect pest management in cotton significantly benefit in reducing the load of chemical pesticides and cost of protection. This technology is an alternate option to chemical pesticides to curb the menace of the PBW due to management difficulties with the present pest control tools.

印度棉农从Bt 中获益从商业化（2002 年 3 月）到 2013-14 年的棉花种植。2014年起，全国棉花产区发生粉红铃虫（PBW）疫情。由于对杀虫剂和杀虫剂的抗性，害虫恶化并变得更成问题，无法通过目前的管理实践得到控制。然而，本研究采用了一种非化学方法来改变 PBW 的行为，并与现有管理策略进行比较评估其有效性。使用专门的信息素和诱剂应用技术对粉红铃虫 (SPLAT-PBW) 进行了交配中断技术的区域范围管理试验。2017-18 年在 154 英亩和 206 英亩的 2018-19 年期间在印度卡纳塔克邦的 Raichur 区施用 500、750 和 1250 克/英亩的诱饵，记录了对 PBW 的显着控制。结果表明，发现以 500 g/英亩施用的 SPLAT-PBW 是最佳的，因为最小的莲座花 (8.23%)、绿铃损害 (7.36%)、小室损害 (8.41%) 和更高的产量 (33.59 q/ ha) 与农民的做法相比，即使在喷洒 5-6 轮杀虫剂后，其产量仍为 22.33 q/ha。在第 5 周结束时，田间样品中存在 40.36% 的信息素活性成分。这表明 SPLAT-PBW 诱饵中信息素的缓释机制。棉花害虫管理的非化学方法显着有助于减少化学农药的用量和保护成本。由于现有害虫控制工具的管理困难，该技术是化学杀虫剂的替代选择，以遏制 PBW 的威胁。
