Changes in lysine decarboxylase (LDC) activity caused by Sitobion avenae (F.) feeding on two winter triticale cultivars (cvs) were studied. The aphid fecundity and values of intrinsic rate of natural increase showed that cv Witon was less susceptible to S. avenae than cv Tornado. The grain aphid feeding on more susceptible triticale caused a decrease in the LDC activity, with exceptions of root tissues after two weeks of the feeding. In case of less susceptible cv Witon reduction of the LDC activity was observed only during initial period of S. avenae feeding. Later the aphid infestation induced activity of the LDC within tissues of cv Witon.
研究了麦长管蚜（Sitobion avenae (F.)）取食两个冬小黑麦品种后赖氨酸脱羧酶（LDC）活性的变化。蚜虫的繁殖力和内禀自然增长率表明，与“龙卷风”品种相比，“威顿”品种对麦长管蚜的敏感性较低。取食更易感小黑麦的谷蚜会导致LDC活性降低，但取食两周后的根组织除外。对于较不易感的“威顿”品种，仅在麦长管蚜取食初期观察到LDC活性降低。之后，蚜虫侵染诱导了“威顿”品种组织内LDC的活性。
