Chemical composition and bio-pesticidal values of essential oil isolated from the seed of Heracleum persicum Desf. ex Fischer (Apiaceae)

Abstract

The present investigation was aimed to analyse the chemical composition of essential oil isolated from Heracleum persicum Desf. ex Fischer and assess its lethal and sub-lethal effects against Tribolium castaneum (Herbst). Essential oil from hydro-distilled seeds of H. persicum was analyzed by gas chromatography-mass spectrometry (GC-MS), and hexyl butyrate (50.58%), octyl acetate (9.80%) and hexyl hexanoate (8.75%) were found as principal constituents. Repellent activity, contact and fumigant toxicity and antifeedant effects of this oil were assessed against the adults of T. castaneum. The essential oil strongly repelled T. castaneum adults even at the lowest concentration (0.035 μL cm -2 ). Complete repellency (100%) occurred when the highest concentration (0.212 μL cm -2 ) was applied for 8 h. T. castaneum was very susceptible to H. persicum oil at both contact and fumigant bioassays. In the fumigant toxicity, essential oil killed the larvae, pupae and adults and significantly decreased larvae emerged from treated eggs. LC 10 to LC 40 values of fumigation adult's bioassay as sub-lethal concentrations were used to evaluate the antifeedant effects. H. persicum essential oil has significant antifeedant effects on T. castaneum adults and decrease of feeding happened when oil concentrations increased. The results of the present study indicate that essential oil of H. persicum, with wide bio-effects on T. castaneum, is a source of biologically active agents which may potentially prove to be efficient insecticides.Additional key words: essential oils; Heracleum persicum; toxicity; repellent; antifeedant.* Corresponding author: asgar.ebadollahi@gmail.com Received: 12-07-14.

Genetic variability and heritability of acid-adaptive soybean promising lines

“…First, the number of chemical components of essential oils identified in our study varied from 18 to 43 with a average per population of 32 different molecules identified. A similar average number per population (31.1) has been identified by Radjabian and his colleagues (2013) and similar numbers and ranges have been recorded in previous studies: 33 (Radjabian et al 2014), 21-35 (Radjabian et al 2013), 32 (Saeidnia et al 2005;Firuzi et al 2010;Ebadollahi, et al 2014), 23 (Hajhashemi et al 2009). However, our results are expanding the existing diversity of chemical molecules present and identified in hogweed populations with lower (18) and higher numbers (43) never obtained before.…”

“…Similarly to the number of chemical compounds identified, the range of the oils yields present in Iranian populations of H. persicum was also expanded by our results compared to the existing literature. Indeed, several rates obtained here were largely higher than the ones published in previous studies: 3.8% (Radjabian et al 2013), 1.6-4.9% (Radjabian et al 2013), 4 (Hajhashemi et al 2009, 1.6 (Ebadollahi et al 2014), 1.8 (Firuzi et al 2010). The populations located in Polur, Lalehzar and Yazd presented the lowest oil yields of our study, with respectively 2.22%, 2.24% and 2.55%.…”

“…48,49 Several investigations on other genus such as Heracleum also showed that octyl conjugated of butyric, acetic, and octanoic acids constitute the main SCFAE in essential oils of Heracleum genus. [50][51][52][53][54] This similarity in major SCFAE of both genus may reflect the pervious viewpoint about Tordylieae tribe of Apiaceae which also showed close phylogenetic characters. 55,56…”

Harmful Effects on Oryzaephilus surinamensis (L.) and Tribolium castaneum by Food Grade Antioxidants and their Formulations in Peanut Kernel

“…In our case, reduction of the weight in both insect could be due to an inhibition of feeding after 5-7 days. Many studies reported a high anti-feedant activity in insects using extracts of leaves and stems, essential oils, antioxidants, commercial insecticides and chemical compounds [28][29][30][31][32][33][34]. Particularly, Shtykova et al [11], could establish an anti-feedant activity close to 1 (complete inhibition of feeding) on pine we evil with BHT microcapsules containing Eudragit copolymer and surfactant.…”
