| 摘 要： | 本文测定了不同时期松阿扁叶蜂Acantholyda posticalis Matsumura越冬幼虫虫体、血淋巴内氨基酸含量，并对影响幼虫抗寒的氨基酸进行了探讨。结果表明：越冬幼虫体内含有常见的17种氨基酸。从越冬初期至越冬期，氨基酸种类并没有发生变化，但各种氨基酸含量变化不同，丙氨酸、谷氨酸、脯氨酸、精氨酸和胱氨酸随着温度的下降呈增加趋势。幼虫虫体氨基酸含量增幅最大的为丙氨酸，比越冬初期增加了28．8％，其次是脯氨酸、酪氨酸、苯丙氨酸，分别比越冬初期增加了9．4％、6．4％和5．4％．其他氨基酸增加不明显；幼虫血淋巴内氨基酸中的丙氨酸、胱氨酸和谷氨酸含量分别比越冬初期增加了94．6％、80．2％和19．6％。因此认为这些氨基酸与低温抗寒密切相关。

| Abstract: | The study measured contents of amino acid in body and blood of the Over - Wintering Larva in different period . The amino acids that affected cold hardiness of over - wintering larva were also discussed. The results showed that there were seventeen amino acids in the larva s body. The kind of amino acid had no change. But the contents of amino acid changed. The contents of ALA, GLU, ARC, PRO, CYS were increased with the decrease of the temperature . The contents of body' s ALA of the Over - Wintering Larva increased 28.8% . The contents of PRO, TYR, PHE were increased 9.4%, 6.4%, 5.4%,Respectively, but the others had no obvious change. The contents of blood's ALA, CYS, GLU of the Over - Wintering Larva were increased 94.6 % , 80.2 % , and 19.6 % , respectively. Therefore these amino acids should be considered to be closely related with cold hardiness of over - wintering larva. |
