Scope

Main Technical Content: 5. Monitoring Methods 5.1 Monitoring Locations and Timing - Conduct monitoring in rice-growing areas and their surrounding environments, focusing on rice fields, as well as areas such as field edges, mountain slopes, forested areas, and weed-infested ditches where the pest overwinters and causes damage. - Phase 1 (early March–late May): Focus on seedbeds and transplanted fields. - Phase 2 (June–August): Focus on rice fields. - Phase 3 (September–November): Focus on rice fields and nearby habitats where the pest survives. 5.2 Monitoring Methods 5.2.1 Light Traps - Combine light traps set up at fixed monitoring points with early morning collection of captured adults for counting to monitor peak adult activity. 5.2.2 Overwintering Pest Survey - Conduct surveys in 2–3 villages per affected county after rice harvest and before seedling cultivation. Survey every 10 days in weed-infested areas near rice fields, mountain slopes, ditches, and wetlands, using a grid-based random sampling method (no less than 0.1 square meter per point) to inspect weed bases and soil for adults. 5.2.3 Host Plant Traps - Use host plants (rice) to trap overwintering adults and observe their migration into rice fields. - Select a monitoring point 15 days before rice seedling cultivation and place pots (30×30 cm) containing 100 rice seeds with 10-day seedlings near seedbed cultivation areas. Survey feeding spots and adult counts per pot. 5.2.4 Seedbed System Survey - Start from the three-leaf stage of seedbeds and survey every 3 days until transplanting. Monitor only adults. Select representative early-, mid-, and late-sowing fields (1 each) and use visual sampling (5 random points per field, 0.1 square meter each) to convert results to per-square-meter pest counts. 5.2.5 Field System Survey - After rice transplantation and greening, survey every 7 days until harvest. Select representative early-, mid-, and late-sowing fields (1 each
