The codling moth is the most destructive insect pest of pears and apples worldwide. Females deposit eggs on or near fruit and the hatched larvae bore into the fruit and tunnel to the core. As they near development, they eat out an exit hole which they plug with frass. Fruit attacked by codling moth cannot be used for fresh shipment or for commercial canning.
“The codling moth has been the key pest in South African pome fruit orchards since the species was first reported in the country in 1885. The infestation potential of codling moth in South Africa is one of the highest in the world, and moths may be active over as much as 8 months of the year. Codling moth causes extensive damage to apples and pears, with stone fruit being only occasionally attacked. The use of insecticides remains the primary means of controlling codling moth in South African pome fruit orchards, with up to 11 different insecticides being used for control.”
