Prunus amygdalus, commonly referred to as the almond tree, is predominantly dependent on insect pollinators for fruit set. However, during its blooming season in late winter to early spring, insect activity tends to be limited. This phenomenon may be attributed to factors such as sparse vegetation, suboptimal soil temperature, and unfavorable weather conditions.
The aim of the study is to sample potential pollinators and visiting insects of P amygdalus during its flowering period in two different habitats (Plot 1 and 2) using white, blue, and yellow colored pan traps. To prevent bias in sampling, pan traps were placed both at ground level and 75 cm above ground level in sets of three for 24 hours, then collected the next day, and specimens were transferred to falcon tubes containing 70% alcohol. Sampling was conducted on March 12th, 16th and 20th, 2024, in Ankara, Turkey. The collected insect specimens were prepared as museum material using insect pins appropriate for their size. Diagnoses were made using different keys.
Our investigation explored diversity across habitats, pan trap colors, and heights. Plot 2 showed significantly greater insect species diversity compared to Plot 1, supported by Shannon diversity indices (H plot 1=0.9192, H plot 2=1.5339). Comparing color groups within Plot 1 and Plot 2, white exhibited slightly higher diversity (H =-0.467) than blue (H =-0.446) and yellow (H =-0.459). Ground-level traps displayed higher diversity (H =-0.706) than elevated traps (H =-0.497).
In conclusion, our study reveals that white pan traps exhibit superior efficiency, likely attributable to the prevalence of white flowers during the sampling period. Furthermore, the comparatively heightened insect diversity in Plot 2, in contrast to Plot 1, is hypothesized to be explicable by the phenomenon of edge effect.
