摘要
选用经田间鉴定抗蚜性表现不同的１０个小麦品种，在室内外较系统地研究了其对禾谷缢管蚜和麦长管蚜存活、生长发育和生殖的影响，分析了室内外试验结果的相关性．结果表明，小麦品种的抗生性并不能造成若蚜个体的直接死亡，但对若蚜发育历期、成蚜寿命和产仔数影响显著，差异均达极显著水平或显著水平．其中对两种蚜虫若蚜发育历期的影响室内外表现了较好的一致性，可作为小麦品种抗蚜性鉴定的主要指标；其次是对成蚜产仔数的影响。
This paper deals with the effect of wheat varieties on main life parameters e.
g., the survivals, growth and development, and reproduction of two wheat aphids
Rhopalosiphum padi and Macrosiphum avenae , and analyzed the correlativity of
experimental results in glasshouse and field. Ten wheat varieties were selected, which have
been demonstrated the different resistance to wheat aphids in former field experiment. The
results show that the resistance of these wheat varieties did not obviously affected the
mortality of nymphal aphids, but significantly affected the development duration of nymphal
aphids, and the longevity and fecundity of adults. The effect of various wheat varieties on the
development duration of nymphal aphids of two species in glasshouse was correspondent with
that in field. Therefore, the nymphal development duration could be used as one of the most
important indexes identifying the anti aphid of wheat varieties. Moreover, the fecundity of
R.padi adults in glasshouse was correspondent well with that in field.
