Investigation of the effectiveness of trapping Cydia pomonella larvae with chemical insecticide impregnated bands

The effectiveness of bands made from different types of material and impregnated with insecticides to trap codling moth larvae was investigated. The results show that bands made from old clothes were better than those made from woven bags or corrugated strips. 68.42% of larvae were trapped by bands made from old clothes. The relative effectiveness of insecticides was, in descending order, Lorsban (Chlorpyrifos), dichlorvos, Beauveria bassiana, difluron, beta-cypermethrin. Lorsban achieved larval mortality of up to 98.20%. A 500 part dilution of Lorsban was the most effective achieving larval mortality of 91.61%. A mixture of a 500 part dilution of Lorsban and a 50 part dilution of Beauveria bassiana was an ideal combination for controlling codling moth larvae; effective for 40 days with larval mortality 96% after 37 days.
