An example is the Egyptian cotton leafworm, which is one of the main pests on the cotton crop in the Arab Republic of Egypt. The main control methods now used against this insect are hand-picking of egg-masses and aerial spraying of pesticides. Both are intensive, and little increase in their efficiency is possible. The structure of the cropping system is such that relatively minor alterations in the crop rotation may have a marked impact on leafworm population dynamics at relatively low cost. The technical issues involved in these alterations are well within the realms of possibility. But to implement them would require the development of a comprehensive view of the agricultural production system as a whole, a high sensitivity to the needs and decision-making frameworks of the Egyptian <em>fellah</em>, and an understanding of the biology of the cotton leafworm.</p></div>","PeriodicalId":100064,"journal":{"name":"Agriculture and Environment","volume":"5 3","pages":"Pages 201-211"},"PeriodicalIF":0.0,"publicationDate":"1980-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0304-1131(80)90001-6","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88569104","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In principle, odours can be measured only by using techniques which include the human nose. But sensorial techniques have many disadvantages for routine purposes. As an alternative approach many authors have tried to determine odour intensity by measuring the concentration of one or more of the volatile constituents of odorous air. The choice of the compounds to be measured in such an approach is very important. In piggery wastes about 150 volatile compounds have been identified. Most of these compounds are presumed to be products of anaerobic microbial degradation of the waste constituents. The microbial pathways leading to the formation of the various volatile compounds in the wastes are indicated in this paper. In addition, the overall process of the conversion of high molecular waste constituents to low molecular weight compounds is discussed.</p><p>Finally, it is suggested that certain volatile waste constituents, which are strongly related to the degradation of protein and/or plant fibre residues, are suitable for monitoring instrumentally. It is concluded that <em>p</em>-cresol and volatile fatty acids to a large extent meet the requirements for such indicator compounds.</p></div>","PeriodicalId":100064,"journal":{"name":"Agriculture and Environment","volume":"5 3","pages":"Pages 241-260"},"PeriodicalIF":0.0,"publicationDate":"1980-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0304-1131(80)90004-1","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77427262","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
