Fu cДЃd BДЃ-HakД«m, an FAO expert in the EMPRES Project, was one of these. In addition, we asked various colleagues for information about the practices of their own forbearers. All the questionnaires also addressed the techniques and problems of food storage. The TihДЃma questionnaire emphasized date palm pests and termites, that for Ta cizz, Ibb and YДЃfi c coffee pests, and that for WДЃdД« Hadramawt wheat and the date palm pests. In addition, questionnaires about indigenous approaches to pest control were distributed in TihДЃma, Ta cizz, Ibb, and the southern governorates. Methods used in data collectionД¤For data collection and analysis, we used the methods described in Sallam and Ba-AngoodвЂ™s paper on insect diversity in this volume. These same practices are also useful in recently developed approaches to agriculture, and have a rightful place alongside more recent concepts of pest management. The archaeological vestiges of large-scale hydraulic works and of terraces built on steep slopes of mountains stand witness to the ability of Yemeni farmers in ancient times to manage available natural resources and to preserve those resources for centuries.ДЈThis paper presents some practices that our forefathers employed for agricultural pest control. Yemeni farmers adopted different agricultural practices and techniques, including constructing canals, dams and weirs, and developing different ways to harvest water. 4ДўAs we follow the history of agriculture in Yemen we find that farmers developed a great store of knowledge, elaborated through generations and centuries. 3 Although this expedition ended tragically with most members dying of disease, its results were later published. 2 The history of insect collection in Yemen started in the 18th century, with the Danish expedition of Frederick V. 1 As far as insects are concerned, some references to beekeeping date back to about 1000 BC. 4 Niebuhr, M., 1792, Travels through Arabia and other countries in the East, Edinburgh Hansen, T., (.)ДЎAgriculture in Yemen dates back at least 5000 years.3 Hacker, H., 1999, History of collecting insects in Yemen.2 Ingrams, H., 1942, Arabia and the Isles, London.and Deutsche Gesellschaft fur Technische Zusammenarbeit, 1 (.) 1 General Department of Plant Protection.
