ABSTRACT

It has been shown in a previous work that 0.2% nicotine sulfate + 1% mineral oil was highly effective on all stages of dubas bug, Ommatissus binotatus lybicus De Berg., in the laboratory. Therefore, its toxicity as an insecticide was investigated in the field. Population density was determined before spray , then mortality was followed at intervals of: 1/24, 1,4,7,10,15,20 and 30 days, and it was: 100, 97.6, 89.4 , 76.2 , 64.8 , 55.5 , 46.7 and 43.2% respectively. Insecticide residue was detected at the same intervals up to the 10lt’ day, and it was : 22.22 , 21.4 , 7.45 ,and 0.77 part per million. These results indicate a very high toxicity of about 90% after 4 days. Nicotine was relatively persistent throughout the 1st day , then it dissipates very quickly until no residue was detected after the 10lh day. Hence we recommend nicotine sulfate as an insecticide for the control of dubas bug instead of the widely used organophosphorous compounds which are an environmental pollutants. Nicotine sulfate can be manufactured from the by product of the Tobacco and Cigarretes Industry, which amounts up to 2000 tons annually. It can be supplemened by growing tobacco spices of high nicotine content.
