摘要: Membrane feeding studies were conducted to determine the effects of raw juices and chemical extracts leaves aphid-resistant (ICV-12) aphid-susceptible (ICV-1) cultivars cowpea [Vigna unguiculata L. (Walp.)], on survival, growth, reproduction aphidAphis craccivora Koch. Life table demographic statistics cohort population subsequent generations estimated. Compared ICV-1, leaf ICV-12 exhibited significant (P<-0.05) adveres aphid reproduction. Raw juice ethyl acetate extract in both water sucrose significantly limited performance. The adverse long-term often more extreme than those resulting from a diet distilled alone. Methanol showed an intermediate level aphids, being generally less that but greater hexane. other extracts, hexane or media did not affect Overall, it was determined antibiosis governing modality aphid-resistance ICV-12.
