Figure 1:
![Relative attraction of CBB (parasitized with Metaparasitylenchus hypothenemi and non-parasitized) to 14 light wavelengths compared to the control (570 nm). The asterisk-labeled treatment was statistically different to the control using the χ2 test (P = 0.01). Relative attraction (%) was calculated using the number of borers that chose the treatment and control, applying the formula: [(treatment) (100) / (treatment + control)].](https://sciendo-parsed.s3.eu-central-1.amazonaws.com/65f35797812d8816c96ad496/j_jofnem-2024-0011_fig_001.jpg?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Content-Sha256=UNSIGNED-PAYLOAD&X-Amz-Credential=AKIA6AP2G7AKOUXAVR44%2F20251028%2Feu-central-1%2Fs3%2Faws4_request&X-Amz-Date=20251028T000718Z&X-Amz-Expires=3600&X-Amz-Signature=db39bbd53e9d92244e1e6bdf8dbc64615ba7c2df8144e3caa16d555eb6b51400&X-Amz-SignedHeaders=host&x-amz-checksum-mode=ENABLED&x-id=GetObject)
Response of coffee berry borer females (parasitized by Metaparasitylenchus hypothenemi and uninfected) attracted by 14 different wavelengths (nm) compared to the control (570 nm) inside a T-shaped olfactometer_ The frequency of response (n=50) to each treatment and control was compared using a square Chi test_
