    • Abstract


      Topical and oral application of penfluron toPapilio demoleus Linn indicated that 7·6 μg of penfluron was needed through topical method to produce 50% mortality. Penfluron treatment caused a marked reduction in growth to a significant level of 42% in oral administration at dose 1·96 μg and 35% in topical application at sublethal dose 1·52 μg over that of control larva. The efficiency ofPapilio demoleus to grow on citrus plant was very much affected.
