Succession of borer complex and their relation to major biotic factors in Sugarcane (Saccharum officinarum L.) under North Bihar condition

Kumbhar CR and AK Rai

Five borer pest species were recorded namely early shoot borer, Chilo infuscatellus (Snell.); root borer, Emmalocera depresella (Swinhoe); top borer, Scirpophaga nivella (Walk.); plassey borer, Chilo tumidicostalis (Hampson) and pink borer, Sesamia inferens (Walk.) found to infest sugarcane crop at their different growth stages in North Bihar during 2013-14. Top borer had been observed as major pest followed by early shoot borer and root borer, respectively while plassey and pink borer had been recorded as a minor pest based on injury symptom. In succession two groups of pests i.e major and minor which were founded on the crops form seedling to maturity stage.Per cent dead heart infestation of these borer ranges from 02 to 25.0, 02 to 20.0, 02 to 9.0, 01 to 10.0 and 01 to 5.0 and their peak occurred on July 1st and September 1st (bunchy top), April 2nd, May 1st and Aug. 1st fortnight and no clear trend appearance for pink borer.
