Compared the Efficiency Of Botanical Extract Oxamatrin and Bio-insecticicd Abamectin to Controlling Myzus persicae Aphid Insect on Hybrid Eggplant Solanum melongena in Greenhouses

Abstract

This research carried out in one of the greenhouses for the 2010-2011 season. Transplant eggplant Barcelona species being the most common and chosen two kinds of modern insecticides the first one is: botanical extract insecticide Oxamatrine and the second was bio-insecticide Abamectin is derived from fungi to controlling an insect of peach green Myzus persicae, then used Three concentrations of each pesticide. egg hatching of egg treated pesticide Abamectin was reduced to 9.5% at the highest concentration 0.05 ml active ingredient / liter of water, while the effect was lighter when less concentrations. While for botanical extract Oxamatrine did not have an impact effect on the percentage of eggs to hatch. and continued influence these pesticides on the Emerging nymphs from treated eggs where the mortality percentage to 58.9% when using Abamectin, either for Oxamatrine has reached 36.66%. .The treatment of new hatching nymphs resulted in Abamectin pesticides concentration of 0.05 ml active ingredient / liter of water to the death of all the nymphs after seven days, compared with 92 .5 death of nymphs treatment during Age latter and the same concentration of the pesticide either for extract vegetable Oxamatrine reached the highest death of 73.9% when treated nymphs first instars after one day of treatment, compared with 57.25% for the nymphs treatment last instars' with the same concentration and after one day, too. The impact of these transactions reflected on the final quantitative production of the crop, where increased weight of winning each plant to 7.75, and 6.20 kg / plant when using Abamectin and Oxamatrine respectively either the number of fruits / plant stood at 62.75 and 59.88 when Abamectin and Oxamatrine, respectively, and finally on the weight of the fruit reaching 118.2 and 98.6 g when Abamectin and Oxamatrine respectively., which demonstrates the effectiveness of the use of these alternative pesticides to protect the eggplant and insect control using the IPM programs.
