Of major importance in realizing the potential of edible insects as a core element in improving food security, sustainable food production, and biodiversity conservation, are developments in sustainable exploitation of wild edible insect populations and in (semi-)cultivating and farming edible insects. Such developments can draw on both western science and indigenous knowledge. Oecophylla smaragdina Fabricius Hymenoptera: Formicidae, of which particularly the queen brood is commonly consumed in Thailand and the Lao PDR, is believed to have the potential to act as flagship/umbrella species in forest conservation and management, to be incorporated simultaneously as biological control agent and direct source of human food in agroforestry practices, and to be (semi-)cultivated. We provide a detailed account of indigenous knowledge of O. smaragdina and ant brood collection practices from the Vientiane Plain, Lao PDR, through focus group discussions and participant observations, and then reflect on sustainability and conservation issues, and on semi-cultivating constraints and possibilities embedded in indigenous knowledge and ant brood collection practices.

AbstractIn mixed cocoa-coconut palm plantations in Malaysia the palm spadices provide large, stable nesting sites for Dolichoderus thoracicus (Smith) in contrast to impermanent sites on cocoa and on the ground. D. thoracicus and the arboreal leaf-nesting Oecophylla smaragdina (Fabricius) both benefit from the mixed system which also provides a more stable food supply from honeydew-producing Homoptera. A scoring method showed that about 50–200 O. smaragdina or 200–2000 D. thoracicus on a cocoa tree can protect it effectively from Helopeltis theobromae Miller (Hemiptera: Miridae). The relatively greater efficiency of O. smaragdina as a biological control agent is associated with its actively dispersive predatory behaviour in contrast to the localized concentration of D. thoracicus workers at sites such as cocoa pods where it tends honeydew-producing Homoptera, and where it acts largely by deterring H. theobromae. Despite its biological control potential, the painfully biting O. smaragdina, unlike D. thoracicus, is normally considered unacceptable to plantation staff. Nevertheless it should be recognized as valuable in integrated pest management of cocoa pests especially where D. thoracicus is difficult to establish.

Oecophylla smaragdina or weaver ants is social insect that has an important role in the ecosystem. One of its main function is as a biological control agent in agriculture. The use of weaver ants in an effort to develop a biocontrol continues and increases, this has caused the significant decrease of the natural population of O. smaragdina. Therefore, the weaver ants rearing is needed to maintain its existence in natural habitat without excessive exploitation. The purpose of this study were to determine the effect of different types of feed i.e. snails, earthworms, and okara (tofu by-product) in the production of weaver ants kroto; and to determine the different of treatments of feeds provided to the production quantity of weaver ants kroto. The experimental method used in this study with a completely randomized design. Treatment was given by different protein sources feeding i.e. snails (Pomacea canaliculata), earthworm (Lumbricus rubellus), and okara. Five replicates were appliead for each treatment. Earthworms fed ants produced highest number of kroto with total of 1,030 individuals and weight 87.4 gram in total. Snails fed ants produced 866 individuals and weight 73.1 gram. Okara fed ants produced 543 individuals and weight 45.9 gram.
