Damage potential and control of the common mormon butterfly, Papilio polytes Cramer on citrus

Studies were conducted to know the damage potential and effect of insecticides on leaf area feeding larval mortality common Mormon butterfly, Papilio polytes Cramer in homestead garden germplasm center Patuakhali Science Technology University (PSTU) campus laboratory, Department Entomology, PSTU, Patuakhali, Bangladesh during October December 2016. Ten Citrus host plants such as Kagoji lime-BAU-1, BAU-2, BAU-3, BAU-4, BARI kagoji, elachi lime, sweet orange, jamir pumelo used study materials. To determine effects mortality, five treatments viz., T1 = Voliam flexi 300SC @ 0.5 ml/l water, T2 1.0 water T3 Bioneem Plus T4 T5 control applied. Under natural field conditions, highest percentage infestation was recorded followed by malta while lowest kagoji 23 30 November, At top canopy, orange (56%), BAU-4 (8%). middle jambura (12%). lower BAU-3 (40%), significantly infested leaves per branch observed (51.39%) lime (10.86%). canopies, no significant difference among different citrus varieties. The (6%) consumed 4th instar larva (Voliam water) treated leaf, consumption found (control) at 3 HAT. percent (100%) larvae plant, (70%) plant. No untreated (T5) plant.
