Biological control of fruit flies in Hawaii: Factors affecting non-target risk analysis
Examples from both classical and augmentative biological control of fruit fly pests in Hawaii are used to address several important factors in assessing non-target risks of introduced fruit fly parasitoids. Expand
Exotic biological control agents: A solution or contribution to arthropod invasions?
International guidelines, national regulations and scientific methods being used for exotic natural enemies in biological control have changed to require appropriate specificity testing, risk assessment and regulatory oversight before exotic natural Enemies can be released. Expand
The impact of exotic parasitoids on populations of a native Hawaiian moth assessed using life table studies
The objective of this study was to determine the relative contribution of the seven parasitoid species to the population dynamics of U. stellata by constructing partial life tables, and it suggests that in large part disappearance is the result of predation. Expand
Several examples, some spectacular, are available of successful applications of weed biocontrol approaches with plant pathogenic agents in agricultural and rangeland situations. The overallExpand
Differential parasitism of seed-feeding Cydia (Lepidoptera: Tortricidae) by native and alien wasp species relative to elevation in subalpine Sophora (Fabaceae) forests on Mauna Kea, Hawaii
Interpretation of results is hindered by lack of knowledge of autecology of moths and wasps, origins, phylogeny, systematics, competitive ability, and physiological limitations of each wasp species, which should be incorporated into risk analysis for biological control introductions and invasive species programs. Expand
Differential parasitism of seed-feeding Cydia (Lepidoptera: Tortricidae) by native and alien wasp species relative to elevation in subalpine Sophora (Fabaceae) forests on Mauna Kea, Hawaii
Alien parasitic wasps, including accidental introductions and purposefully released biological control agents, have been implicated in the decline of native Hawaiian Lepidoptera. Understanding theExpand
Biological Control of Pest Non-Marine Molluscs: A Pacific Perspective on Risks to Non-Target Organisms
Empirical evidence is presented supporting the proposition that biological control of nonmarine mollusc pests has generally not been demonstrated to be safe and effective, which are the basic measures of success, which often accompany contemporary biological control programs, although without rigorous evaluations. Expand
Classical biological control against insect pests in Europe, North Africa, and the Middle East: What influences its success?
Many factors can affect the success and failure of classical biological control. However, these factors have mainly been studied independently of each other, which leaves their relative importanceExpand
Are specialists really safer than generalists for classical biocontrol?
A selective review of the impacts of nine particularly-well-studied exotic natural enemies suggests a sole focus on specialists in classical biocontrol might be an unreliable means to reduce ecological risk. Expand
The value of existing regulatory frameworks for the environmental risk assessment of agricultural pest control using gene drives
Abstract The application of (synthetic) gene drives is a powerful tool to control populations of insects that are agricultural pests, vectors of diseases, or a threat to biodiversity potentiallyExpand
