Maria Jessica Laput Moron, a native and citizen of the Philippines, petitions for review of the Board of Immigration Appeals’ (“BIA”) summary affirmance of an Immigration Judge’s (“IJ”) denial of her applications for asylum and withholding of deportation. Because transitional rules apply, Kalaw v. INS, 133 F.3d 1147, 1150 (9th Cir.1997), we have jurisdiction under 8 U.S.C. § 1105a(a). We review for substantial evidence, see Meza-Manay v. INS, 139 F.3d 759, 762 (9th Cir.1998), and we deny the petition for review. Moron’s reliance on prior written threats by the guerrillas as evidence of past persecution is unavailing. See Lim v. INS, 224 F.3d 929, 936 (9th Cir.2000) (<HOLDING>). Additionally, substantial evidence supports
holding that threats standing alone generally do not constitute past persecution holding that harassment threats and one beating did not constitute persecution holding that threats standing alone  constitute past persecution in only a small category of cases and only when the threats are so menacing as to cause significant actual suffering or harm  holding that personal disputes do not constitute persecution holding that threats combined with the murder of a fellow preacher constituted past persecution
