Abstract
Living organisms are affected by climate changes, which impact their reproduction or extinction. This study shows that when temperatures rise, a type of fly, Ceratitis capitata, increases, and its numbers decrease with the arrival of cold months. There is a positive relationship between temperature and the fly population, with a correlation coefficient of 0.13. On the other hand, as relative humidity increases, the relationship turns negative, with the population decreasing and a correlation coefficient of -0.01. In contrast, the species Bactrocera zonata and Bactrocera oleae increase with decreasing temperatures and decrease with increasing temperatures. The correlation type is strongly negative, at -0.67 and -0.46, respectively. Additionally, their populations increase with high humidity and decrease with low humidity, where the positive relationship is 0.27 and 0.13. By examining the climate variables, represented by temperature and relative humidity, in relation to the three fly species using the marginal probability function, it was found that Bactrocera zonata is best suited to the climate during this period.
