This section brings together the full Buzzlogs acoustic detection method. Each heading below opens to its own page, giving you clear, practical guidance for early varroa‑related stress detection.
Detection Manual — Field Guide (Version 1.0)
This manual provides a simple, practical method for detecting early varroa‑related stress using short, time‑specific acoustic recordings. It is designed for everyday beekeepers and focuses on clear, repeatable steps that reveal subtle changes in colony health long before visual symptoms appear.
The Three Recording Windows
The Buzzlogs detection method relies on three specific recording windows because honey bee colonies follow a strong daily rhythm. Each window reveals a different layer of colony function — overnight recovery, daytime workload, and night‑time stability. By recording at the same times each week, early stress becomes clear and comparable, even before visual signs appear. This page explains why timing matters and what each window shows in both healthy and varroa‑stressed colonies.
Early Stress by Recording Time
Stress shows up differently depending on the time of day, and varroa creates distinct early signatures long before mites can be seen. This guide walks through each key time window and explains what appears first, why it happens, and exactly what to look for in your recordings. It’s a practical reference for recognising early changes in fundamentals, harmonics, midband density, and ventilation behaviour.
Weekly Workflow
This page outlines the simple weekly routine that makes the Buzzlogs method consistent and reliable. By recording three short slices, noting weather, saving spectrograms, and marking weekly changes, beekeepers can track early stress without invasive testing. The workflow is designed to be quick, repeatable, and easy to follow — even for beginners.
Weekly Acoustic Review Template
The Weekly Acoustic Review Template gives beekeepers a clear, easy way to assess their recordings. Each section focuses on one of the three time windows and highlights the key signs to look for. This template keeps notes short, observations simple, and weekly comparisons straightforward, making early detection accessible to everyday beekeepers.
Weekly Checklist (Quick Guide)
This one‑page checklist is a fast field reference for the Buzzlogs method. It lists the three recordings, the early signs, the night signs, and the weekly status categories. Beekeepers can use it during inspections or while reviewing spectrograms to stay aligned with the detection manual without needing to read the full guide each time.
