An arboreal ant species by nature, the Asian weaver ant Oecophylla smaragdina F., (Hymenoptera: Formicidae) colony's social structure composition was investigated in depth. Brood and barrack nests were collected from the African oil palm (Elaeis guineensis) canopies and Limau kasturi (Citrus microcarpa) orchards, and dissected. All castes morpholog...

Highlights •Asian weaver ant foraging activity is diurnal. •Veteran foragers' demonstrated supervision acts towards smaller individuals ( first social insects report) for safety measures during heat peaks. •Air temperature and relative humidity are positively and negatively associated with activity, respectively. •Intensive ground-dwelling forag...

Oecophylla smaragdina F., the Asian weaver ant, is one of the oil palm plantation's (Elaeis guineensis) potential predators, for the invasive bagworm species Metisa plana Walker, but this ant is a nuisance species that irritates plantation workers with their sharp bites. Here we assess the foraging activities (FA) of O. smaragdina's major workers,...

Study of the Asian weaver ant colony distribution and nesting occupation pattern in oil palm plantations of South-East Asia (Malaysia-Indonesia)

The bagworm (Metisa plana) is a recurrent indigenous invasive defoliator in oil palm plantations. Moderate foliar injury can cost up to 40% yield loss and more for years. The main objective of this review is to disseminate published research demonstrating the versatile services that would benefit farmers by adopting the Asian weaver ant into their...

The review of Oecophylla smaragdina foraging activity and population dynamics towards an assessment of potential adoption as a biological control agent in the oil palm plantations industry in Malaysia and Indonesia. Additionally, it does open the way for others crops in Asia. The ant species is a model for evolution, behavioral, ecological and appl...

This review discusses the distribution pattern, nesting style, mating behavior, and colony structure of the Asian weaver ants (Oecophylla smaragdina) in Asia. Recent findings suggested that weaver ant occurrences are not only limited to tropical rainforests biome, agroforestry and large monoculture fields, but have encroached human rural habitation...

An estimation of the population size density of the Asian weaver ants Oecophylla smaragdina at colony level (1), on a defined area (2) and on large oil palm plantations of 500 ha or 1000 ha superficies (3). Such estimation help to evaluate the number of colonies necessary to control the invasive bagworms Metisa plana & Pteroma pendula species in su...

The bagworms Metisa plana is a recurrent indigenous invasive defoliator in oil palm plantations. A moderate foliar injury can cost up to 40% and above of yield loss for years. As an effective biological control agent (BCA) or by integrated pest management (IPM) on insect pests of economic significance affecting major crops of the countries in Asia-...

Asian weaver ant, Oecophylla smaradigma is a nuisance species, effect the plantation employee due to their painful bites. The O. smaragdina was reported as one of the potential predators for the invasive bagworm species, Pteroma pendula in the oil palm plantation. Despite their important role in the plantation, however the study on the ecology and...

A field study was conducted to elucidate the predatory activities of the ant Oecophylla smaragdina in the bagworms Pteroma pendula in oil palm plantations at Teluk Intan Perak, Peninsular Malaysia and various fields in Sabah and Sarawak (MPOB) from November 2010 to June 2013. The ant was found to occupy both taller (> 7 m) and shorter palm stands (...

Reports on the population dynamics of ants in agricultural production are rare. To break through this, we focus on weaver ants of the genus Oecophylla in which estimation of the worker density in a given area.
