Climatic Conditions Favoring the Spread of Dubas Bug Infestation on Agricultural Crops in Diyala Governorate

Abstract

This study investigated the climatic conditions conducive to the spread of the Dubas bug disease on agricultural crops in Diyala Governorate, highlighting the percentage of affected area by the disease. The aim of the study is to elucidate the favorable climatic conditions for the spread of the Dubas bug disease on agricultural crops in the province. This is because it is one of the influencing factors on agricultural crops, posing a threat to living organisms. Therefore, it serves as a safeguard for the environment against the risks of diseases and pollution.

The study relied on weather data and information from the Meteorological Authority and the Ministry of Agriculture in Diyala Governorate. The study concluded the following results:

1-The suitable months, according to the requirements of the Dubas bug and considering maximum temperature, are from January to April and from October to December. During these months, a moderate level of suitability was recorded with an average score of 15.5.

2-The months of June, July, September, and January were found unsuitable for the appearance of the Dubas bug. This suggests that these months are not conducive to its spread, with a score of 14.9.

3-The degree of suitability varied. An excellent suitability score of 25°C was observed as the optimal temperature based on the Dubas bug's requirements. Meanwhile, moderate suitability ranged between 15°C and 36°C, while unsuitability was indicated by temperatures below 14°C and above 38°C.
