摘要: Loss of cane and sugar yield caused by the combined occurrence of Tetramoera schistaceana (Snellen) and Chilo sacchariphagus (Bojer) were measured in pesticide treated and untreated areas during 2014-2016. The results indicated that the in untreated areas, percent dead-heart was 8.30%-58.83%, the percent stalk injured was 26.73%-96.67%, the percent internodes bored was 4.40%-25.87%, and the effective stem number was reduced by 4440-21900 stalk/ha. Measured yield and sugar yield loss results showed cane yield was reducedby5.32-44.53 T/ha; the yield loss percent was5.92%-44.53%; the sugarcane juice yield decreased by 1.73%- 3.28%; the sucrose content reduced by 0.33%-5.63%; sugarcane brix dropped by 0.70-6.36 BX; the fibre and reducing sugar increased by 022%-0.98% and 0.11%-1.58%, respectively. It was confirmed that in majority of sugarcane fields in Yunnan, China, T schistaceana and C. sacchariphagus cause severe reduction of sugarcane and sugar yield.
