This research was performed between 2000 and 2003, to explore the role of the mechanisms in conferring insecticide resistance of Aphis gossypii populations collected from the cotton areas of the Mediterranean region of Turkey using biochemical methods. These populations collected from Antalya and four different fields of Adana and standard A. gossypii populations were used throughout the studies. Total esterase activity associated with insecticide resistance was detected using kinetic microplate assay. All populations were characterized using polyacrylamide gel electrophoresis (PAGE) to determine the esterase banding pattern. In addition, insecticide resistance resulted from insensitivity of acetylcholinesterase was investigated using microplate assay. According to results from the biochemical assays, four cotton aphid populations were found to have high esterase activity. Esterase banding patterns were determined with electrophoresis. This demonstrated that all Turkish cotton aphids collected were the same banding pattern as the standard resistant 1081K population in the PAGE. In modified AChE study, target site sensitivities of the populations were investigated using pirimicarb and demeton-S-methyl as inhibitors. All of these populations were identified with differing levels of sensitivity to these chemicals.

The purpose of this study is to investigate to which extent yield components are related to canopy components in Gerek-79 cv. of bread wheat. The data on biological yield, grain yield, 1000-grain weight, harvest index, fertile spikelet number, spike number, spike length and plant height were used. The canonical correlation analysis was fulfilled using the biological yield, grain yield, 1000-grain weight, fertile spikelet number and harvest index as the first set, called yield components, and spike number, spike length and plant height as the second set, called canopy components. The results of the canonical analysis showed that a high canonical correlation of 0.923 was achieved between yield and canopy components. The largest contribution to the first canonical variable for yield component was made by biological yield. The first canonical variable for the canopy component was most affected by spike length. The computed squared multiple correlation coefficients confirmed that the first canonical variable for canopy components had a substantial predictive power for biological yield (0.730) but much less for the other yield components. The squared multiple correlations also showed that the first canonical variable for yield components was a better predictor of canopy components, being 0.784 to predict plant height.

A theoretical work was performed to model and design the bottom of a cylindroidal type mouldboard plow. The aim of the work was to compare and evaluate the performance of the two different types of mouldboard plow (designed and type 113) in two soil depths (15-20 and 20-25 cm) and three forward speeds (4.4, 6, 9 km/h). Some design indicators involved in the study; draft force, von mises stress and bending moment which were analyzed with using a finite element methods (FEM). Some soil indicators involved; plowing appearance, the degree of tilth, the evens of the plowing surface and the angle of inclination. The data were then analyzed statistically with using randomized complete block design for all indicators and characteristics. Designed mouldboard plow was found to be significantly superlative over the 113 mouldboard plow with all design indicators since the draft force, von mises stress and bending moment were less. The results showed draft force, von mises stress and bending moment increased by increasing forward speed with a constant depth, and also showed the draft force, von mises stress and bending moment increased by increasing the depth with a constant speed for both plows in the theoretical and experimental results. Best performance results were obtained in 15-20 cm soil depth with 9 km/h forward speed.

Key Words: Mouldboard plow design, draft force, finite element methods (FEM), bending moment
