The damage by the black-tipped sawfly, Acantholyda posticalis posticalis, has been increasing all over the area of Pinus koraiensis stands in Korean Peninsula. This study was conducted to provide basic information for the management and control of this pest by investigating the feeding quantity of pine needles during the larval stage. The total needles damaged in the larval stage of the black-tipped sawfly were 9,584mm in length on an average and those of female and male were 11,774mm and 7,394mm, respectively. The total length ingested actually was 7,797mm and it was equivalent to 81.4% of the total length damaged. Early larval stage showed a little feeding and it was equivalent to 17% of total quantity. On the contrary, the feeding quantity in late larval stages of fourth and fifth instar amounted to 83%. The number of the frass excreted per larva was about 1,160, and the difference between male and female was not shown, whereas it showed remarkable difference among larval instars.
Key words: control, feeding quantity, larval stage, instar, frass
