Chemical composition, fumigant toxicity and repellency of Zhumeria majdae essential oil against Rhyzopertha dominica F. (Coleoptera: Bostrichidae)

Mehrnoosh Nikooei and Chamran Hemmati

Chemical composition of the essential oil from Zhumeria majdae and its fumigant and repellent activity were investigated against Rhyzopertha dominica. Dry aerial parts of the plant were subjected to hydrodistillation using a modified Clevenger-type apparatus and the chemical composition of the volatile oil was studied by GC-MS. Fourteen components (99.36% of the total composition) were identified. Linalool (47.29%), camphor (34.33%), geraniol (3.95%), limonene (3.33%) and camphene (2.98%) were found to be the major constituents of the oil. The mortality of 1-3 days old adults of the insects increased with increase in concentration and exposure time from 3 to 24 h. In all of concentrations, total mortality was achieved after 12 and about 21 h of exposure, respectively. The oil had strong toxicity against all of stages of Rhyzopertha dominica. On the basis of LC50 values, larval stages were the most tolerant and adult the most susceptible stage in this species. In general, susceptibility of eggs was significantly decreased with increasing their age, while older larvae were more tolerant than young ones. Also, the essential oil had significantly repellency to R. dominica. The many diverse bio-effects of Z. majdae essential oil confirmed that it is a good candidate for management of R. dominica.
