摘　　要：为探究矿物源农药对冬型中国梨木虱卵的防控效果,本文测试比较了4种矿物源农药(石硫合剂、松脂酸钠、矿物油、石硫·矿物油)和1种化学对照农药(吡丙醚)对冬型梨木虱卵的防控效果.结果表明,石硫合剂、松脂酸钠、矿物油、石硫·矿物油、吡丙醚的LC_(50)值分别为1.14 Be°、1107.98 mg/L、3564.13 mg/L、1202.24 mg/L和75.85 mg/L.在4种矿物源农药中,以石硫合剂杀卵效果最好,其次为松脂酸钠、石硫·矿物油和矿物油,建议选用石硫合剂、石硫·矿物油作萌芽前的杀卵药剂.In order to provide a basis for screening mineral source pesticides against winter-form pear psylla(Psylla chinensis),lithium sulphur mixture,sodium rosinate,mineral oil and lithium sulphur·mineral oil were used as the experiment materials,with the chemical pesticide pyriproxyfen as the control.The results showed that the LC_(50) of lithium sulphur mixture,sodium rosinate,mineral oil,lithium sulphur·mineral oil and pyriproxyfen was 1.14 Be°,1107.98 mg/L,3564.13 mg/L,1202.24 mg/L and 75.85 mg/L,respectively.Of the four pesticides with mineral sources,lithium sulphur mixture showed the highest ovicide efficiency,followed by sulphur•mineral oil,sodium rosinate and mineral oil.The ovicide effect of mineral pesticides against pear psylla eggs was superior to that of the chemical pesticide.Thus,lithium sulphur mixture and sulphur·mineral oil are recommended to be used as the ovicide agents before germination in the prevention and control of pear psylla.
