This pest is active throughout the year. The larvae overwinter in the stubble and water-shoots. The attack remains low during April-June and increases in July. Its incidence is highest during October-November. There are no outward symptoms of the attack of this pest. Entrance or exit holes on the attacked canes can be seen only after stripping. A larva sometimes damages up to three nodes and the cane may be attacked at several places. The cane yield and sugar recovery are adversely affected in the case of serious attack. The only available control for this pest is a biological technique involving Trichogramma chilonis.
As far as I know chemical control not feasible and ineffective for Chilo auricilius. Cheers, Nadine

I think it is possible to use mating disruption. We have very positive results here in Spain for the control of Chilo suppressalis in rice. Efficacy has demonstrated to be excellent in wide area approaches for this species. As far as I know the pheromone was isolated in 1986 (see J. Chem. Ecol. 12:1377-1388). The company I work for could be interested in the study this approach.
As far as chemical control is cncerned, we use to recommand in extreme cases for other sepcies of stem borers attacking cereals in the Sahel, systemic insecticides such as carbosulfan or Carbofuran .f these products are registerd in your Country, you can try any of them and see what will be the result.
We successfully controlled Chilo infuscatellus in Pakistan with Insecticide Fipronil when it was used in granular form. You can also check it on chilo auricilius.
dear kumar, why don't you combine between pheromones trap from Rullipm Semiochemicals of Chilo auricilius, the Sugarcane stalk borer. and after first detection of adult on trap you start spraying an insecticide indoxacarb or Lufenuron as the last one is an anti-moulting agent, leading to the death of larvae and pupae Lufenuron has no effect on the adults. After biting a lufenuron-treated crop, a female adult ingests a crop meal containing lufenuron which is subsequently deposited in her eggs. Lufenuron prevents most female adult’s eggs from hatching or maturing into adults and thus prevents and controls adult pest populations by breaking the life cycle.
Lufenuron is used for the control of Lepidoptera and Coleoptera larvae on cotton, maize and vegetables, and of citrus whitefly and rust mites on citrus fruit.or any IGR with long persitance action
Dear Kumar
Chemical control of stem borer
Recommended insecticides for granular application :
•Carbofuran 3G @ 25 kg ha-1
•Phorate 10 G @ 10 kg ha-1
•Cartap 4 G @ 25 kg ha-1
•Fipronil 0.3 G @ 25 kg ha. –1
•Chlorpyriphos 10G @ 10 kg ha-1
Recommended insecticides and doses for spray (Twice at 7-10 days interval)
•Monocrotophos 36 WSC @ 1100 ml ha-1
•Chlorpyriphos 20 EC @ 2000 ml ha-1
•Endosulfan 35 EC @ 1100 ml ha-1
•Cartap 50 WP @ 800 g ha-1
•Fipronil 5 SC @ 800 ml ha-1
•Acephate 50 WP @ 950 g ha-1.
DEAR KUMAR; I too does agree Rajashekar, Amadua and azzendine. What is important is spraying before the proliferation stage starts.
Only chemical option can save the crop. Do not rely on trichogramma and pheromone. Pheromone and trichogramma do not work in high field temperatures. These options are only for mild weather or greenhouse farming.
