Ant Bait Control in Olives and Crop applications with
Distance PLUS by Sumitomo Chemical
Distance Plus ant bait is based on the insect growth regulator Pyriproxyfen, it acts as a juvenile hormone mimic, preventing the queen from laying viable eggs and preventing metamorphosis of larvae into adult ants.
Because of its unique mode of action, Distance Plus causes a gradual reduction in worker numbers until the colony collapses for long-lasting ant control.
Distance plus does not need to be eaten to be effective and unlike other baits, prevents a new generation of ants replacing the old.
Olives is a crop where ants feature greatly in the population dynamics of a key pest the blackscale (Saissetia oleae). Natural control agents include coccinellid lady beetles, lacewings and parasitic wasps. Ants interfere with their ability to control populations of black scale but tending and protecting the scale in return for honeydew reward.In trials in western Victoria, Distance® PLUS Ant Bait has been very effective in reducing the populations of scale tending ants, mostly meatants (Iridomyrmex purpureus) and black ants (Iridomyrmex rufoniger andothers). These ants aggressively tend and protect black scale and reduce the effectiveness of natural predators such as coccinellid and lacewing larvae and parasitoid wasps. The use of Distance® PLUS Ant Bait as part of the program to reduce sap-sucking insects such as black scale in olives,fits very nicely with the IPM approach increasingly being adopted by Australian farmers.
Has been used effectively in the control of Fire ants and African bigheaded ant (aka coastal brown ant). It has also been tested on a wide range of others species including those normally less attracted to typical corn and oil-based baits.
Distance plus is the only product available in an IGR that can be used in Olives and Agricultural applications (as at August 2013).
Another important but often overlooked consequence of ants in
crops is their protection of sap-sucking insects in return for honeydew reward,
otherwise known as mutualism.
A wide variety of ants seek the honeydew produced by aphids,
scale, mealybugs and leafhoppers, and in exchange, protect these pests from
their natural enemies.
Proliferation of these pests also promotes sooty mould on
the crop. There have been a large number
of studies worldwide showing the benefits of excluding ants from crops and the
resulting reduction in pest populations resulting from increased numbers of
beneficial insects and easier access to their sap-sucking prey. For instance, Australian
researchers have shown that by physically excluding ants from citrus canopies
they can dramatically reduce the number of live soft scale (Coccus hesperidum).
Baiting is an effective option to reduce ant
abundance in canopies. Olives is
another crop where ants feature greatly in the population dynamics of a key
pest, the black scale (Saissetia oleae). Natural control agents include
coccinellid lady beetles, lacewings and parasitic wasps. Ants interfere with
their ability to control populations of black scale but tending and protecting
the scale in return for honeydew reward.To find out more information, please click the below links or order online now!
Application and timing:
For broadcast application using hand-held or motorised spreaders or by aerial application: 2-4Kg/Ha
For specific nest treatments: apply 2-10g over and around the nest (depending on species and nest size)
Bait should be applied in early spring or summer during the colony build-up phase where ants are actively foraging.
Do not apply during the heat of the day when ants are not foraging. Under hot conditions, best to apply early-mid-morning and then late afternoon.
Do not apply if rainfall is expected and do not irrigate until ants have harvested the bait (usually within 24hrs)
Bait granules easily absorb moisture and become less attractive to ants.
Always keep bait containers tightly sealed to maintain freshness (fresh bait is always more attractive than unfresh bait)Distance® Plus should be used within 3 months of opening. However, the unopened product will remain fresh for at least 2 years. Species tested on:
- Red imported fire ant
- Tropical fire ant
- Bigheaded ant
- yellow crazy ant
- little fire ant
- black ants
- singapore ant
- pony ants
- meat ants
- tyrant ants
