Introduction: Madagascar hissing cockroaches (Gromphadorhina portentosa) exhibit a symbiotic relationship with mites (Androlaelaps schaeferi) in their natural habitat. Mites play a vital role in cleaning the cockroaches and preventing fungal infections, while also benefiting from the food and shelter provided by their host. However, in enclosed environments like museums and laboratories, this symbiosis can lead to challenges, including limited locomotion for the cockroaches and potential health risks due to mite overpopulation.
Objective: This research aims to develop an effective and non-invasive method for maintaining mite-free Madagascar hissing cockroaches using UV light treatment. By utilizing UV light, we seek to address the limitations of existing care techniques, such as manual cleaning methods that are both labor-intensive and ineffective. Methodology: Three enclosed tanks will be outfitted with UV lamps set to different durations (15, 30, and 45 minutes), while one tank will serve as a control without UV light. Mirrors will be strategically placed to ensure comprehensive UV exposure, targeting mites residing on the cockroaches’ undersides. Weekly sanitation of the enclosures using water and vinegar will complement the UV treatment. Mite populations will be assessed weekly by counting the number of mites on each cockroach under a dissecting microscope.
