Transcript of Rind Borer

Citrus borers were first recorded in Malaysia and also discovered in some parts of western Indonesia.Eggs are laid in clusters on the underside of citrus fruit. The larvae bore into the peel after they hatch and later tunnel into the pulp and pith. Larvae are reddish/yellow initially then turn green at the time of pupation.
Mature caterpillars drop to the ground on silken threads to pupate in the soil. The moths, about 1cm long, emerge after 10 days and are strong nocturnal fliers. Canavalia gladiata (horse bean)
Cassia fistula (Indian laburnum)
Citrus aurantiifolia (lime)
Citrus aurantium (sour orange)
Citrus hystrix (mauritius bitter orange)
Citrus limon (lemon)
Citrus maxima (pummelo)
Citrus medica (citron)
Citrus reticulata (mandarin)
Citrus sinensis (navel orange)
Citrus x paradisi (grapefruit) Host Range(Species attacked by the pest) Life cycle of Rind borer eggs larvae pupa adult Nature of Damage Fruit - internal feedingFruit - lesions: black or brown
Fruit - premature drop the larvae penetrates the rind of the fruit and eats just below the surface. Later instar larvae penetrates more deeply, making a loosely woven silken tube around them. This results in rotting and premature fall of the fruit. Management(Pest Control Strategies) Infested, damaged or fallen fruit should be removed and young fruits covered to prevent infestation by C. sagittiferella spreading. Bagging
Exclusion of infested plant parts
Insecticides - synthetic insecticides are sprayed from the flowering stage to 60 days at seven to 14 days interval. there is an organic way of controlling rind borer - the farmer sprays goat manure and urine extract to the pummelo plants at one to two weeks interval at the onset of flowering. To prepare the extract, he soaks overnight 40 kg of fresh goat manure and 1 gallon of goat urine in a drum.
He then adds sili, ginger, and Panyawan extract or OHN to the goat manure and urine extract and then sprays the mixture to the pummelo plants. Apparently, the odor of the manure and urine drives away the moths of rind borer, and the OHN, Panyawan, ginger, and sili extracts kill the moth and the larvae. In this practice, the damage of rind borer is less than 5 percent. "http://www.plantwise.org/default.aspx?site=234&page=4279&dsID=16857"
