Evaluation on insect biodiversity in Diyarbakır agricultural areas

INTRODUCTION[|]Since ancient times, people have used a variety of methods to increase efficiency from the unit area in agriculture. The methods to combat diseases and harmful factors causing economic loss in vegetable production are undoubtedly one of the methods that human beings have constantly used and developed in agriculture. It is also known that since the 20th century, people have been using chemical drugs to fight against harms in agricultural areas after the presence of particularly chlorinated hydrocarbons. However, in recent years, the idea that chemical pesticides can cause serious damages to the environment and human health has gained importance. However, it is thought that chemical pesticides affect not only human and environmental health damages but wildlife biology, but also cause some species to decrease and eventually to disappear. Therefore, it can be said that some insect species generations are affected by chemical pesticides which are used extensively.[¤]METHODS[|]In this context, the areas in Dicle plain in Diyarbakir where the agriculture is very concentrated and the mountainous areas outside of the plain and where the agriculture is relatively less, were visited and the plants found in agriculture and non-agricultural areas were examined and the existing insect species were collected and their concentrations were examined with the aid of atrap and aspirator. It was also discussed with 90 producers operating in the region to determine the intensity of use of chemical pesticides in the area. As a result of the observations made, it has been determined that more fruit and vegetables are produced in the mountainous areas except for the Dicle ovary where wheat, cotton and maize production is concentrated in the Dicle ruby ​​which has suitable fields for cultivation.[¤]RESULTS[|]In the areas where field agriculture is overused, the number of triplications is 36% higher, whereas in the fields where garden agriculture is done, it is found that the number of triplications is 43% higher. [¤]DISCUSSION AND CONCLUSION[|]As a result of these spraying, some groups were observed to be almost free from other insect groups. In this study, it was tried to determine the effect of chemical pesticides used in agricultural areas of Diyarbakır on species diversity of insects.[¤
