Abstract

Antifeedant activity of plant extract from Mentha piperita was tested against the cowpea seed beetle, Callosobruchus maculatus. Dry ground plant was subjected to hydrodistillation using a Clevenger-type apparatus. The resulting oil contained menthone (28.9%), menthol (28.5%), and pulegone (6.9%) as the major compounds. LC50 of M. piperita essential oil was 25.70 μL/L air and mortality increased as the doses of essential oil increased. LT50 values were 3.29, 2.74 and 1.89 h at 100, 200 and 500 μL/L air, respectively. The results of persistence test of oil revealed that essential oil of M. piperita on C. maculatus adults was 5.44 days. It was clear from the repellency index that M. piperita essential oil has strong repellency at 90, 180 and 360 μL/L air concentration. The results showed that M. piperita essential oil has significantly affected the relative growth rate, relative consumption rate and feeding deterrence index of C. maculatus adults and it was concentration-dependent. The efficiency of conversion of ingested food has decreased while the concentrations are not statistically different at 5% level compared to the control group. It seems that essential oil can be used as low-risk insecticides.

薄荷精油对豇豆种子甲虫的化学成分及杀虫活性研究(鞘翅目:野蛾科)

试验了胡椒薄荷提取物对豇豆种子甲虫的抗药性。使用Clevenger型装置对旱地植物进行加氢蒸馏。所得油含有薄荷酮（28.9%）、薄荷醇（28.5%）和普勒酮（6.9%）作为主要化合物。胡椒M.pipita精油的LC50为25.70μ。在100、200和500μL/L空气中，LT50值分别为3.29、2.74和1.89h。油的持久性试验结果表明，胡椒M.pipita对斑螯蟹成虫的精油有效期为5.44d。由驱避性指数可知，胡椒M.pipita精油在90、180和360μL/L空气浓度下具有较强的驱避性。结果表明，胡椒挥发油对斑蝥成虫的相对生长率、相对消耗率和摄食威慑指数有显著影响，且具有浓度依赖性。与对照组相比，摄入食物的转化效率有所下降，而浓度在5%的水平上没有统计学差异。看来精油可以用作低风险杀虫剂。

期刊介绍： The Journal of Entomological and Acarological Research (JEAR), formerly the Bollettino di Zoologia Agraria e di Bachicoltura of the Institute of Entomology of the Università degli Studi, Milano, was founded in 1928 by Remo Grandori. Thereafter, Minos Martelli and Luciano Süss hold the direction of the Journal until December 2011. In January 2012 the Editor decided for the new open-access on-line version of JEAR. The Journal publishes original research papers concerning Arthopods, but reviews, editorials, technical reports, brief notes, conference proceeding, letters to the Editor, book reviews are also welcome. JEAR has four main areas of interest: -Entomology (systematics; morphology; biology; biotechnology; agriculture, ornamental and forest entomology; applied entomology; integrated pest management; biological control; apiculture and apidology; medical, urban and veterinary entomology; etc.) -Stored product pests (biology; integrated pest management; etc.) -Insect Ecology (behaviour; biodiversity; taxonomy; plant insect interaction and ecosystems; biological control; alien species; etc.) -Acarology (systematics; morphology; biology; parasitology; control; etc.) The publication of manuscripts is subject to the approval of the Section Editor who has knowledge of the field discussed in the manuscript in accordance with the principles of Peer Review; referees will be selected from the Editorial Board or among qualified scientists of the international scientific community. Articles must be written in English and must adhere to the guidelines and details contained in the Instructions to Authors.
