In this study was researched the cause of the decline in bee populations in recent years. For this purpose, effects of Cypermethrin on two ecotypes of honey bee (Apis mellifera anatoliaca and Apis mellifera caucasica) and German wasp (Vespula germanica) were examined.
In this study, the label dose of Cypermethrin (40 ml / 100 L water) and 6 different doses (20, 10, 5, 2.5, 1.25 ml/100 L water) diluted with 50% were given to bees by orally. The alive and dead bees were controlled every 12 hours. Syrup without pesticide was used in the controls.
As a result, life span of bees was increased depending on the doses used. German wasp`s life span was shorter than that honeybee. Relationship between pesticide doses and life times has been linear. Regression coefficients for Vespula germanica, Apis mellifera anatoliaca and Apis mellifera caucasica were calculated as R2 = 0.936, R2 = 0.845 and R2 = 0.866, respectively.
