Rhinoceros beetles have destroyed my coconut trees and some palms. They are now attacking my mango

trees and boring holes. How do I get rid of them? Chonburi area.

This is a Dept of Agriculture affiliate program with main office in Chonburi.  I have not been in touch for over 3 years and I don't know their current status of services offered, but they did have an active biological control program for pests of coconut palms.

There have been multiple discussions over the years, on this forum and the dog and snake forum, (a.k.a. Plants, Pets & Vets.)  Maybe you can search for some of that information. 

 

The two big categories of management are chemical control (stem injection with systemic insecticide, spraying with a residual barrier insecticide), which is an option for ornamentals, but problematic with food products due to likelyhood of pesticide contamination. 

Then there is the "organic", preventive approach, with multiple methods available (sanitation/cleaning up of beetle breeding habitat, trapping of adult beetles, repellents, biological control of larvae and adults, building soil fertility, plant health and natural pest resistance), a couple of which are presented in the Indian video. 

 

Practical issues that influence decisions on control methods are size of trees and access to the foliar crown, size of property and number of trees, nature of the property and status of downed wood, debris piles, including neighboring properties/trees and possibility or not for a community cooperative program. Because adult beetles can fly in to your trees from other nearby property, even if you've cleaned up your larvae habitat. 

 

Physiologically stressed trees are more susceptible to pest infestation. Dry season drought stress, nutritional deficiencies, methods and materials that are damaging to the beneficial soil biology, like use of high salts NPK chemical fertilizers, herbicides, fungicides and insecticides can be contributing factors. 

 

Red palm weevils are often associated in tandem with the CRB infestation, so you have to be aware of their different life cycle and management. 

Coconut hispine beetle and coconut black headed caterpillar are other common devastating pests to be considered for management.
