In the Mekong Delta, Vietnam, the predatory weaver ant Oecophylla smaragdina was abundant in about 75% of the sweet orange and 25% of the Tieu mandarin orchards. With a three-level scale (low, moderate, high), farmers assessed the incidence, severity and yield loss of fruit caused by major pests. With abundant O. smaragdina, sweet orange farmers assessed a lower pest infestation or yield loss for the citrus stinkbug Rhynchocoris humeralis, the aphids Toxoptera aurantii and T. citricidus, the… 

The effectiveness of weaver ant (Oecophylla smaragdina) biocontrol in Southeast Asian citrus and mango

Weaver ants alone may work effectively in some settings whereas in other cases ant control needs to be supplemented with additional IPM control measures to provide a viable alternative to chemical pest control.

The weaver ant, Oecophylla smaragdina (Hymenoptera: Formicidae), an effective biological control agent of the red-banded thrips, Selenothrips rubrocinctus (Thysanoptera: Thripidae) in mango crops in the Northern Territory of Australia

It is suggested that the weaver ant is an effective biological control agent of the red-banded thrips, and the use of weaver ants in mango orchards is discussed.

Potential of Oecophylla longinoda Latreille (Hymenoptera: Formicidae) in managing major insect pests in organic cashew production systems

O. longinoda can serve as an alternative to chemical insecticides in Tanzanian cashew protection by controlling major cashew insect pests and compared the resulting cashew yield.

Using weaver ants Oecophylla smaragdina to control two important pests on African mahogany Khaya senegalensis in the Northern Territory of Australia

Data suggested that weaver ants were effective bio-control agents of the two pests of African mahogany, but the yellow looper and bush cricket caused severe damage to the trees.

Effective control of Jarvis's fruit fly, Bactrocera jarvisi (Diptera: Tephritidae), by the weaver ant, Oecophylla smaragdina (Hymenoptera: Formicidae), in mango orchards in the Northern Territory of Australia

This work indicates that weaver ants are efficient biocontrol agents of Jarvis's fruit fly, a major insect pest in mango production in the Northern Territory of Australia.

The effect of weaver ants Oecophylla smaragdina on the shoot borer Hypsipyla robusta on African mahoganies in Australia

1 African mahogany Khaya senegalensis is a high‐value timber tree species widely grown in central Africa, south‐east Asia and northern Australia. Pilot plantings show that the tree grows well in the

Preliminary indications were that self-sufficiency in trophobiont (honeydew) levels may be achieved in two months after colony relocation, and that M. citrifolia is a promising candidate for mixed-planting with this mahogany species.

Predation biology of weaver ant Oecophylla smaragdina (Hymenoptera: Formicidae) in the field of tasar sericulture

A survey was undertaken in the tasar rearing fields in Vidarbha, Maharashtra, India to study the predatory potential of O. smaragdina on A. mylitta and based on the attack and symptoms of predation, the loss (mortality) is also discussed.

Weaver Ant Role in Cashew Orchards in Vietnam

Regular monitoring of the field experiment showed that weaver ants were similar to insecticides for controlling mosquito bugs, blue shoot borers, fruit-nut borers), leaf rollers, and leaf miners in cashew orchards, showing that the ants were able to keep pest damages under the control threshold.

Can Oecophylla smaragdina be used to suppress incidence of CVPD in citrus orchards in Indonesia?

Citrus vein phloem degeneration (CVPD) is the Indonesian name for the Asian form of the devastating and incurable citrus disease known internationally as huánglóngbìng. It is associated with a

Evolution and status of Oecophylla smaragdina (Fabricius) as a pest control agent in citrus in the Mekong Delta, Vietnam

Citrus farmers in the Mekong Delta have a long tradition of managing the weaver ant Oecophylla smaragdina (Fabricius), and her husbandry is a good example of a traditional practice which should be further promoted as an important component of sustainable citrus production.

Traditional knowledge and rationale for weaver ant husbandry in the Mekong delta of Vietnam

The weaver ant, Oecophylla smaragdina Fabricius (Hymenoptera: Formicidae), has long been known as perhaps the first example of human manipulation of a natural predator population to enhance the

The pugnacious ant, Anoplolepis custodiens (Hymenoptera: Formicidae), and its beneficial effect on coconut production in Tanzania

A significant relationship between low percentages of damaged nutlets and high ant scores of the palms could be established and the population of the coconut bug, Pseudotheraptus wayi Brown, decreased significantly.

The effect of colony isolation of the predacious ant, Oecophylla smaragdina (F.) (Hymenoptera: Formicidae), on protection of cashew plantations from insect pests

Fighting events between fully isolated ant colonies were eliminated, and the populations of these colonies were high throughout the cashew flowering and fruiting period, and trees in which O. smaragdina colonies were transplanted suffered little damage.

Relationship between insecticide-acaricide resistance and field control in Tetranychus urticae (Acari: Tetranychidae) infesting roses

Field populations of the twospotted spider mite, Tetranychus urticae Koch, were collected and tested to determine levels of resistance and there was no clear relationship between fenbutatin-oxide resistance and field control.

Mutualism Between Ants and Honeydew-Producing Homoptera

In this review, the term "mutualism" is defined as an association between ants and other insects which is mutually beneficial without neces­ sarily implying obligate dependence or interdependence.

Influence of pesticide information sources on citrus farmers' knowledge, perception and practices in pest management, Mekong Delta, Vietnam

Media, pesticide sellers and extension staff had different influences on farmers' pest perception and management practices depending on the region and intensity of the cropping system, and potentials of different information sources are discussed in relation to developing IPM programmes for citrus.

Hexythiazox resistance in a field population of European red mite (Acari: Tetranychidae) on apples

It is demonstrated that a population of European red mite, panonychus ulmi (Koch), in an apple orchard in Pennsylvania had become highly resistant to hexythiazox, a relatively new acaricide that is not registered for use on apples in the United States.
