  2. Resistance nayan! Ha haha ! Mabisaitodati ! Bakitwalangtalabngayon?

  3. Sa bukid ay mayroongibat– ibang immunity angmgainsekto SUSCEPTIBLE: Can be easily killed MODERATELY SUSCEPTIBLE: Not easily killed RESISTANT (IMMUNE) Cannot be killed under normal dose

  4. What Happens in the Field ? Continued use of 1 Product

  5. What Happens in the Field ? Continued use of 1 Product

  6. What Happens in the Field ?

  7. Remaining Reproduces = + = +

  8. Dumadamiang resistant population Continued use of 1 Product

  9. Lalongdumamiang resistant population Continued use of 1 Product

  10. Mas dumamiang resistant population Continued use of 1 Product

  11. Halos walangnatirana susceptible at moderately resistant population ., Continued use of 1 Product

  12. PaanoMaiwasanangInsecticide Resistance… • Gumamitngmaresistensyangbinhi • Sundinangprinsepyong IPM • Sundinangprinsepyong GAP • Alaminang mode of action (MoA) ng insecticide products / brands • Pagpalit-palitinang Insecticide MoA group • MagpalitngMoA group pagkalipasngisanghenerasyonnginsekto

  13. Insecticide Mode of Action (MoA) A specific Mode of Action will target a specific part/ function of an insect Nerve Feeding + + Growth / Development/ Molting + Respiration + Excretory Digestive + Energy/ Muscle Reproduction + + +
