Insecticides are essential tools for preventing and eliminating insect pest damage that significantly increases the quality and quantity of product that also improve the quality of life of human beings and animals. The study aimed to determine the assessment of insecticide resistance against Black Aphids (Toxoptera aurantii) On Coffee Crops under Abra condition. The Complete Randomized Design (CRD) replicated four times was employed in the study. The treatment was T0 Untreated, T1 Decis EC25 (RR), T2 Decis EC25 (2RR), T3 Decis EC25 (3RR). The study results showed that aphids in Treatment 3 have the fastest movement of the aphids in going to the tip of the vials as a mechanism of the aphids after 30 minutes of inoculation due to too much exposure to insecticides as observed. Moreover, Treatment 3 has the highest percentage of mortality rate in terms of high concentration used in the study that controls black aphids of the coffee crop. The analysis of variance shows significant among all the treatments as percent mortality of black aphids. It was recommended for further validation of insecticide used by farmers to study the target insect pest mechanism, insecticide selection in applying different insecticides based on the insect pest’s susceptibility present in the field human risks, and for environmental impacts. The results could help monitor the survey of insecticide resistance to determine the susceptibility of the target pest. The development of insecticide resistance in insect pests was increasing in the field of agriculture.
