Abstract:

The study investigates the spatial and temporal dynamics of flea beetle infestation on mung bean crops in various districts of the study area. This study examines the factors influencing flea beetle infestation in mung bean (Vigna radiata) crops across different districts in the Amhara region, Ethiopia. The research focuses on pest population dynamics, environmental influences, and agronomic practices. Flea beetle incidence varied significantly by location, with East Belesa showing a moderate mean infestation of 14.1% (SD = 7.7%), while S/muja exhibited the highest mean infestation at 34.3% (SD = 22.9%). Flea beetle density also varied, with S/muja recording the highest density of 11.8 insects/m² (SD = 5.9) and T/gaint the lowest at 7.9 insects/m² (SD = 5.9). Altitude showed a negative correlation with flea beetle infestation, with the highest mean infestation (28%) occurring between 1500-1800 meters and the lowest (8.857%) above 2400 meters, suggesting that higher altitudes may offer less favorable conditions for flea beetles. Previous crop history significantly impacted infestation levels (χ² = 63.852, df = 21, p
