Abstract :

---

The black bean aphid, Aphis fabae is an oli-gophagous pest and due to direct damage in plant and virus transmission is important in sugar beet. This aphid is vector of 30 virus pathogens in differ-ent plants. The high toxicity of common pesticides for human and environmental contamination, along with the emergence of pest resistance, in recent years efforts has been done for introducing low-risk compounds for the control factors of caus-ing damage in plants. In this research, insecticidal activity and nymph production deterrent of five essential oils was studied on the black bean aphid in the laboratory conditions under 25 ± 2°C, 65 ± 5 RH and 16L:8D photoperiods. Mortality was evaluated at different concentrations that ranging from 1.18 to 108.82 µL/L air, and with 6 replica-tions at the interim of 24 hours. The results showed that by increasing dose and time, mortality rate was also increased. The lowest LC50 value was related to Mentha piperita. These results showed that M. piperita oil was more toxic than other essential oils on the black bean aphid, A. fabae. The highest deterrence was related to M. piperita (and the low-est was belonged to Satureja isophylla. Obtaind results of the essential oils described here can be further studied and be used to control the black bean aphid.
