Abstract

The present studies aimed at finding the best concentration of chlorpyrifos and fipronil following mixing with the same and different soil depths in laboratory and field trials. Barrier efficacy of these insecticides was measured by determining wood weight loss kept as bait on the treated soils in the field experiment and length of galleries in the laboratory experiments. Results showed that termites were able to penetrate galleries treated with both insecticides at variable distances. Length of gallery and repellence was concentration dependent. Five percent concentration of both insecticides at 45 cm was the best treatment in comparison with other combination of concentration and soil depths. Maximum gallery length and repellence was observed after the application of chlorpyrifos in comparison with fipronil. Fipronil applied at different concentrations following mixing with the same and with different soil depths was the best treatment as a standard pre-construction step.

毒死蜱和氟虫腈对地下白蚁的防治效果与土壤深度的关系

本研究旨在通过实验室和田间试验，找到在相同和不同土壤深度混合后毒死蜱和氟虫腈的最佳浓度。通过测定田间试验中用作诱饵的木材在处理过的土壤上的重量损失和实验室试验中廊道的长度来测量这些杀虫剂的屏障功效。结果表明，白蚁能够以不同的距离穿透用两种杀虫剂处理过的走廊。廊道长度和排斥性与浓度有关。与其他浓度和土壤深度组合相比，两种杀虫剂在45cm处的浓度为5%是最好的处理。与氟虫腈相比，毒死蜱施用后观察到最大廊道长度和排斥性。在与相同和不同土壤深度混合后，以不同浓度施用氟虫腈是作为标准施工前步骤的最佳处理。

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.
