Fumigant and repellent activities of essential oil from Coriandrum sativum (L.) (Apiaceae) against red flour beetle Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae)

Abstract

The biological activity of essential oil extracted from coriander, Coriandrum sativum L. (Apiaceae) against eggs, larvae and adults of Tribolium castaneum (Herbst) was investigated in a series of laboratory experiments. Bioassays conducted in air-tight glass chambers showed vapour toxicity and strong repellency on Wlter paper arena test towards all the stages used. Responses varied signiWcantly (P < 0.001) within insect stages, dosages and exposures. At 12.0 g/ml dosage, mortality of adults reached 95%, but for 12-, 14-and 16-days larvae, mortalities were 65, 74 and 82%, respectively. On the developmental inhibition, individuals fumigated at the larval stage conWrmed that the percentage of larvae reaching to pupal stage and pupae to adult stage, decreased signiWcantly (P < 0.001) with increasing dosage concentration. The oil fumigation yielded 100% mortality for T. castaneum larvae, pupae and adults at 0.08 g/ml dosage. The oil had fumigant activity against eggs and the toxicity progressively increased with increased exposure times and concentrations. One hundred per cent T. castaneum egg mortalities were obtained with oil fumigation at 20 g/ml and 96 h exposure period. C. sativum oil also showed highly repellent activity to the adults of T. castaneum, with overall repellency was 90% and at a dosage of 12 g/ml repellency was 100% in a Wlterpaper arena test.

Oil and fatty acid accumulation during coriander (Coriandrum sativum L.) fruit ripening under organic cultivation

“…Similar results have been reported in other oilseed species [14,17]. The level of petroselinic acid was in accord with values previously reported for coriander ranging from 51.6% to 90.7% [5][6][7]. The highest amount of petroselinic acid was reached between 18 and 35 DAF, in agreement with results of Msaada et al [10] which emphasized that a period of 32 DAF was sufficient for use of coriander fruits.…”

“…The seeds also have medicinal uses in treatment of rheumatism, gastrointestinal complaints, flatulence and gastralgia, worms, insomnia, anxiety, loss of appetite, and glycemia [3,4]. In industry, the main product from coriander is distilled oil and solvent-extracted oleoresin for aroma and flavor production [5]. Coriander oils are familiar not only in the perfumery, food, beverage, and pharmaceutical industries, but also in medicine.…”

Effect of Hexaflumuron on Gustation and Reproduction of Adult Boll Weevil

“…Subsequently, twenty 90-day-old unsexed S. zeamais adults were placed in the center of each dish. The numbers of weevils in the control (NC) and treatment (NT) dishes were recorded after 30, 60, 90, and 120 min (Islam et al 2009). A repellency assay was carried out in an environmentally controlled chamber (25 ± 1 °C, 70 ± 10% RH, and 12:12 h L:D photoperiod).…”

Post-harvest technology of pulses

“…The Montreal Protocol on substances that deplete the ozone layer (Fields and White, 2002), increased insect resistance and increased consumer demand for chemical-free grains have led grain processors to seek alternatives to control storage pests. The persistent use of these pesticides has been reported to disrupt biological control systems by natural agents, leading to outbreaks of insect pests, widespread development of resistance, undesirable effects on non-target organisms, and environmental and human health concerns (Kells et al, 2001;Collins et al, 2005;Pimentel et al, 2007Pimentel et al, , 2009Islam et al, 2009). The increasing concern about their adverse effects has highlighted the need for the development of selective insect control alternatives (Fields and White, 2002).…”
