Abstract

Crematogaster rogenhoferi is widely distributed in Lao Cai and several other provinces of Vietnam, where its eggs were collected as food to meed high market demand. This study aimed to develop techniques for harvesting, post-harvest care and farming C. rogenhoferi under the forest canopy in Lao Cai province. The results showed that the most effective method of harvesting involed opening the nest at the base of the host tree, leaving about 5% of the nest containing eggs, and then hanging the remaining nest shell back on the original host tree while providing an artificial diet next nearly. This approach facilitated nest reestablishment, increased nest size, and enhanced the number of individuals at different developmental stages, as well as egg weight. Farming C. rogenhoferi on Melia azedarach and Styrax tonkinensis trees at a density of 2 - 4 nests per tree yielded the highest efficiency, producing the largest nests (9.2 - 9.6 cm lengh, 5.3 - 5.4 cm wide) and the greatest numbers of pupae (72.0 - 77.3), larvae (174.7 - 189.7), eggs (265.7 - 342.3) and adults (634.3 - 657.0).
