Augmentative biological control: research and methods to help make it work
While many innovations are now costly, scientifically sophisticated and planned for use in regional-scale projects, new techniques and genetic modifications could become widely available to the agricultural industry.
The state of commercial augmentative biological control: plenty of natural enemies, but a frustrating lack of uptake
Augmentative biological control is in a critical phase, even though during the past decades it has moved from a cottage industry to professional production, and ways to increase application are explored.
Impact of Release Rates on the Effectiveness of Augmentative Biological Control Agents
- Biology, Environmental ScienceJournal of insect science
In most cases, there was an optimal release rate that produced effective control of a pest species and increasing the release rate above the optimal rate did not improve control of the pest and thus would be economically detrimental.
Biological and cultural controls … Nonpesticide alternatives can suppress crop pests
Recognition that partial suppression can greatly reduce the need for OPs will lead to the more widespread adoption of alternatives, and such alternatives may not always be as effective and predictable as conventional insecticide programs.
Toxicity of Insecticides and Miticides to Natural Enemies in Australian Grains: A Review
- Environmental ScienceInsects
A literature review of studies that have conducted chemical toxicity testing against arthropod natural enemies relevant to the Australian grains industry to examine trends and highlight research gaps and priorities found many gaps in testing, leading to unknown toxicity effects for several key natural enemies.
Alternatives to Chemical Control of Insect Pests
In 2011, practitioners and advocates of Integrated Pest Management (IPM) find themselves addressing agricultural, societal, and political pressures worldwide resulting from human population growth; these include preventing losses from pests, dealing with increased human global travel, and addressing global climate change that potentially will shift pest distributions into new areas.
Effective augmentative biological control - importance of natural enemy dispersal, host location, and post-release assessment.
Grounds for the effectiveness of augmentative biological control in outdoor cropping systems are addressed, with special reference to the use of Trichogramma ostriniae in sweet corn and field corn, where low-density inoculative releases can be highly effective.
Assessing the impact of arthropod natural enemies on crop pests at the field scale
- Environmental ScienceInsect science
Tailoring impact assessments will lead to research outcomes that do not simply provide general information about how to conserve natural enemies, but how to use these natural enemies as an integral part of decision‐making.

Augmentative Releases of Entomophagous Species in Annual Cropping Systems
- Environmental Science
A focus on quality control, enhanced effectiveness of released individuals, and ecological and economic assessment of releases is required to increase the use of augmentative biological control in annual cropping systems.
Efficacy of Inundative Releases
- Environmental Science
The value of entomophaga for regulating and controlling agricultural pests has long been recognized (23), but conscious manipulation and utilization of arthropods was all but abandoned by most…
Implementation of biological control
A survey of the present-day application of biological control involving the regular introduction or augmentation of natural enemies is presented, although these have been applied on a much smaller scale.
Field Evaluations of Augmentative Releases of Delphastus catalinae (Horn) (Coleoptera: Coccinellidae) for Suppression of Bemisia argentifolii Bellows & Perring (Homoptera: Aleyrodidae) Infesting Cotton
Observational data suggested that intraguild predation by the existing predator fauna may have limited the potential for D. catalinae to provide biological whitefly control in open field plots relative to the levels observed within the cages, suggesting an absence of statistically significant, antagonistic predator–parasitoid interactions.
Plant compensation for arthropod herbivory
- Environmental Science
A primary purpose for this review is to integrate the forms of compensation reported in the literature in the context of natural and agricultural habitats.
Why do natural enemies fail in classical biological control programs
Why, in biological control campaigns, some introduced enemies fail to reduce pest populations substantially is determined to ensure correct climatic matching of pest and enemy, correct matching of pests and strain of enemy, and the release of sufficient numbers of natural enemies.
Effects of augmentative releases of the coccinellid, Adalia bipunctata, and of insecticide treatments in autumn on the spring population of aphids of the genus Dysaphis in apple orchards
The prevention of egg deposition of aphids in autumn is a promising control strategy and deserves further exploration for practical use.
Suppression of beetles in stored wheat by augmentative releases of parasitic wasps
Assessment of the effectiveness of the parasitoid wasps, Cephalonomia waterstoni, and Choetospila elegans, for controlling Cryptolestes ferrugineus, rusty grain beetle and Rhyzopertha dominica, lesser grain borer found that C. elegans was effective in suppressing R. dominica populations.
Comparison of Trichogramma brassicae (Hymenoptera: Trichogrammatidae) Augmentation with Organic and Synthetic Pesticides for Control of Cruciferous Lepidoptera
Abstract We monitored egg parasitism and larval populations of Pieris rapae (L.) and Trichoplusia ni (Hübner) in cabbage plots treated with point and broadcast releases of Trichogramma brassicae…
Effect of Inoculative Releases of Trichogramma ostriniae on Populations of Ostrinia nubilalis and Damage to Sweet Corn and Field Corn
In sweet corn, inoculative releases of T. ostriniae provide suppression of O. nubilalis populations adequate to reduce damage significantly, and this reduction in damage was consistent for early and late-planted sweet corn.
