Towards more effective and affordable coconut beetle traps!

Towards more effective and affordable coconut beetle traps! The simplest trap models can be marketed for less than ten US dollars and can even be made at home. Please read first the sections highlighted in yellow if you are in a hurry!

The information presented hereunder comes primarily from a confidential website created by Roland Bourdeix starting in September 2025 to document his research and technical trials aimed at improving trapping of Oryctes in Hawaiʻi and other regions. The original website was not indexed by search engines and remained invisible to the public. Since then, an e-Soleau filing and provisional French and United States patent applications have been made, clarifying the rights to the invention and allowing us to disclose a substantial part of the work.

The design of these new traps has been guided by two original principles:

  1. A principle of radical simplification, so that the traps are extremely affordable, and very easy to manufacture and use.
  2. A principle of cumulative synergistic effects. For example, if products A and B both attract insects, but A is more effective than B, product B is not discarded; instead, it is retained and used in combination with product A.

We intend to collaborate with anyone willing to invest the effort to test, use, and improve these traps, regardless of their background, knowledge, or level of expertise. Our goal is to involve a broad community of active participants who share a commitment to addressing the CRB challenge. This collaboration is not limited to those working directly with palms; it can also include people who grow or care for other plants affected by CRB, as well as communities that wish to take an active role in protecting their landscapes and resources.

The main steps in the development and protection process are as follows:

  • August 2025. Invitation to Hawaiʻi by the University of Hawaiʻi West Oahu and by the NiU NOW! community and cultural movement of the Puʻuhonua Society. This visit allowed the inventor to appreciate the full extent of the damage caused in Hawaiʻi by the coconut rhinoceros beetle. Thanks to Dr. Manulani Aluli Meyer, Konohiki for Kūlana o Kapolei, Director of Indigenous Education at the University of Hawaiʻi–West Oʻahu, and to Indrajit Gunasekara, Director of the community coconut program of the Hawaiʻi Department of Land and Natural Resources (DLNR). 
  • November 2025. Filing of Soleau envelope DSO2025027961 for new trap designs. The Soleau envelope (now called e-Soleau) is a service of the French National Institute of Industrial Property (INPI) that provides evidence that a creation existed on a specific date. It serves as proof of prior possession but does not grant exclusive intellectual property rights in the way that a patent or trademark does.
  • June 2026. Formal recognition by the employer that this is an “invention hors mission attribuable,” and that the employer does not wish to exercise its right of attribution. From that moment, the inventor became the holder of all rights attached to this invention and is free to protect, exploit, and promote it in his own name and for his own benefit.
  • June 2026. Filing of a provisional patent application with the French National Institute of Industrial Property (INPI): patent application no. FR2607667, filed on June 9, 2026.
  • June 2026. Filing of a provisional patent application with the United States Patent and Trademark Office: application no. 64/089,908, filed on June 13, 2026.

The title of these patent applications is:

  • Suspended flexible-body traps for capturing insects of the genera Oryctes, Scapanes, Augosoma and Rhynchophorus, pests of coconut palm, oil palm, date palm and ornamental palms.
  • Pièges suspendus à corps flexible pour la capture d’insectes des genres Oryctes, Scapanes, Augosoma et Rhynchophorus, ravageurs du cocotier, du palmier à huile, du palmier dattier et des palmiers ornementaux.

The various sections below describe the research conducted and the characteristics of the invention.

Section 1 — Pests and their palm hosts: economic impact, biology, and behavior

Section 2 — State of the art in trapping: existing trap types and their limitations

Section 3 — New suspended flexible-body traps: description and optimization

Section 4 — Outlook: communication, valorization, and research directions

Many thanks to my friend Philippe Visitainer, who visited me in October 2025
and, having seen the traps, managed to keep the project confidential
during the period required to clarify the legal ownership of the invention.
