Feb 26, 2016 · Weaver ants are tropical insects that nest in tree canopies, and for centuries these ants have been used for pest control in tropical orchards. Trees hosting weaver ants might benefit not only from the pest protective properties of these insects but also an additional supply of nutrients from ant feces deposited on the leaves. In a recent study, we demonstrated that Coffea arabica plants
The weaver ant, Oecophylla smaragdina (Fabricius) (Hymenoptera: Formicidae) is known for an aggressive painful bite and a predator of various insect species. Workers of O. smaragdina, attack and
The ant O. smaragdina is a vigilant and territorial predator of many insect pests in a number of horticultural crops [1].

Jul 17, 2018 · The weaver ant Oecophylla smaragdina is an aggressive predator of other arthropods and has been employed as a biological control agent against many insect pests in plantations. Despite playing important roles in pest management, information about the microbiota of O. smaragdina is limited. In this w
Oecophylla smaragdina has a widespread distribution in tropical Asia and Australia, its range extending from India through Indonesia and the Philippines to Northern Territory and Queensland in Australia. It is an arboreal species, making its nests among the foliage of trees.
Apr 30, 2020 · The green tree ant, Oecophylla smaragdina, is one of only two recognized species of weaver ants. While the identity and functions of chemicals produced and emitted by its congener O. longinoda have been studied quite extensively and serve as a valuable model in chemical ecology research, little comparable information is available about O. smaragdina.
Jan 11, 2020 · Weaver ants are fit to be eaten by people and are rich in protein and fatty acids. The whole lipid content varies from 6.3% to 15.2%, and the predominant lipid components were triacylglycerol 37.4–79.4%, followed by phospholipids 6.1–21.5%. Sterols constitute 0.5–0.8%, and oleic acid is the primary fatty acid.
Feb 4, 2008 · We demonstrate, using near-infrared spectroscopy (NIRS), that individual weaver ants, Oecophylla smaragdina, can be differentiated with respect to their colony and nest of origin. 76.5% of individuals from four colonies could be correctly assigned to their colony of origin; and 79.6% of individuals could be assigned to the correct nest (of two
The red ant, Oecophylla smaragdina Fab. (Hymenoptera: Formicidae) is also known as the weaver ant, green ant, Kerengga red ant, emerald leaf dweller or Indian tree ant. It is distributed in the tropical Old World from India to Tai wan and across Southeast Asia to Australia. This ant nest is arboreal, seen on trees or shrubs and made of living

Weaver ants are voracious predators and have been used as biological control agents for many centuries to control insect pests in Asia ( Oecophylla smaragdina ) and in Africa (Oecophylla longinoda ).
Caste-specific behaviours among social insects are known to be largely influenced by olfactory cues. The present study addresses the question whether individual castes (queen, major and minor) of the weaver ant, Oecophylla smaragdina (Fabricius) differ in the organization of the chemosensory structures on the antenna, maxillary and labial palps. The sensory structures were studied by light and scanning electron microscopy.
NEST Two: Of a total of 674 ants taken from this nest, two size groups are shown by a clear bimodal curve. From this nest, 163 ants are represented as minima and 511 as maxima. Extremes for the minima of this nest are from 1.29 mm. to 2.01 mm. with the mode lying at 1.60 mm. Maxima extremes are from 2.16 mm. to 3.30 mm. with the /85 162 /32
Weaver ants are edible for humans and high in protein and fatty acids. The total lipid content range was 6.3%–15.2%, and the major lipid components were triacylglycerol 37.4%–79.4%, followed by phospholipids 6.1%–21.5%. Sterols are 0.5%–0.8% as the minor components and oleic acid was the most predominant fatty acid.
