Sugarcane and interspeci fichybridsarethemainsource ofraw sugarintheglobe. 9This plant is AU1 cultivated on more than 20 million hectares in more than 10100 countries such as in South America, the United States, Australia, 11South Africa, Southeast and Southwest Asia, and overseas territories of Europe. 12Sugarcane has also been considered as eco-friendly source of energy in the form 13of bioethanol as energy cane. Sugarcane is vulnerable to biotic and abiotic 14stressors which increase the cost of production. Moth stem borers are the main 15entomological problems in all sugarcane-producing countries except Australia. 16The larval stage of stem borers feeds directly on the vegetative tissues that store 17sucrose and therefore directly reduces yield, but larval feeding also provides sites 18for the introduction of disease organisms.

Efficient management of moth stem borers through agroeco23 logical pest management programs is multi-tactic and requires that several 24 ecologically sound control methods be used. We proposed the wide range of 25 management strategies of stem borers based on agroecological practices.
