Aceria sacchari, a new pest mite recorded on sugarcane in Guangxi province, China.

Abstract

Sugarcane iS ONE of the major agricultural industries in China with more than 60% of production in Guangxi province. Insect pests are considered the major constraints on sugarcane yield. In 2011, a new pest mite species was found on the sugarcane leaf sheath on the Sugarcane Research Institute farm at the Guangxi Academy of Agricultural Sciences. The mite was mainly present on the tender leaf sheath during the middle to later growth period. Dark red sponginess appeared on the inner leaf sheath at the peak of infestation with the exterior markedly distorted. White floccules were observed and the damaged area of the leaf sheath turned red-brown. The mite pest was found in Nanning and Baise cities, Guangxi provinces. In Nanning city, the incidence on variety ROC22 was 92.5% while on other sugarcane varieties it was low. In Baise city, the incidence on the same variety was between 65.7 and 98.0% and the pest was not recovered on other varieties. Based on morphological characteristics, the mite was identified as Aceria sacchari (Acari: Eriophyidae) (Channabasavanna, 1966). This species was first recorded on sugarcane in India, and was found to be widely distributed in that country. It has also been recorded in Australia, Philippines and Taiwan province of China. It is believed that the mite might have been introduced into mainland China from Taiwan province in the ROC22 germplasm and plantlets. This is the first report of A. sacchari as a pest on sugarcane in mainland China.
