We reviewed laboratory tests which studied the impact of genetically modified plants on arthropod natural enemies. A total of 18 species of predators and 14 species of parasitoids have been tested, most in only a few experiments. Certain groups (braconid wasps) or species (the green lacewing, Chrysoperla carnea) have attracted much effort, while representatives of others, including whole orders (e.g., Diptera), have never had a species tested. We conclude that laboratory tests are not the… Expand
Transgenic Insecticidal Crops and Natural Enemies: A Detailed Review of Laboratory Studies
TLDR
A continued bias toward studies on a few predator species, especially the green lacewing, Chrysoperla cornea Stephens, is identified, which may be more sensitive to GM insecticidal plants. Expand
Composition of Arthropod Species Assemblages in Bt-expressing and Near Isogenic Eggplants in Experimental Fields
TLDR
The results suggest that some taxa may warrant more specific study, and some sap feeders were more abundant on Bt-expressing plants in some samples in all 3 yr. Expand
Long-Term Assessment of the Effects of Transgenic Bt Cotton on the Function of the Natural Enemy Community
TLDR
Long-term studies in Arizona showed essentially no effects of Bt cotton on natural enemy function in Arizona cotton and showed that minor reductions in density of several predator taxa in Btotton observed in a companion study may have little ecological meaning relative to natural enemy impact on key pests in the system. Expand
COMPATIBILITY OF INSECT-RESISTANT TRANSGENIC PLANTS WITH BIOLOGICAL CONTROL
Transgenic Bt crops expressing proteins derived from Bacillus thuringiensis (Bt) currently are grown commercially in ten countries on over 20 million hectares. Assessing their environmental safety isExpand
RESPONSE OF VARIOUS LACEWING SPECIES (NEUROPTERA: CHRYSOPIDAE) TO SOME PYRETHROID INSECTICIDES
TLDR
Results showed that the insecticide tolerance of these species can differ significantly from each other, that is Ch. Expand
Nontarget Effect of Transgenic Insecticidal Crops: Overview to Date and Future Challenges.
TLDR
The current commercially used Bt crops appear to have little significant adverse effect on nontarget fauna and negative effects on predatory or parasitic insects shown in laboratory experiments have never been demonstrated in greenhouse or field studies. Expand
Bt Crop Effects on Functional Guilds of Non-Target Arthropods: A Meta-Analysis
TLDR
No uniform effects of Bt cotton, maize and potato on the functional guilds of non-target arthropods are found and the importance of using controls not only to isolate the effects of a Bt crop per se but also to reflect the replacement of existing agricultural practices is highlighted. Expand
Investigating the presence of transgenic crop constructs in DNA of organisms of aquatic ecosystems
TLDR
The development of Bt crops beyond single gene events, towards multigene stacked varieties which often contain herbicide resistance genes in addition to multiple Bt genes is discussed, as well as how their use (in conjunction with co-technologies such as glyphosate/Roundup) may impact and interact with aquatic ecosystems. Expand
Integration of Plant Defense Traits with Biological Control of Arthropod Pests: Challenges and Opportunities
TLDR
Host plant resistance and biological control are two of the key pillars of integrated pest management; their potential interactions, whether they are synergistic, complementary, or disruptive, are key in understanding and achieving sustainable and effective pest management. Expand
Genetically Modified Plants and “Non-Target” Organisms: Analysing the Functioning of the Agro-ecosystem
One of the main concerns for a possible adverse environmental effect due to the cultivation of genetically modified (GM) crops is the threat to the biodiversity in the receiving environments whereExpand

TLDR
The results establish that protease inhibitor-expressing plants have negligible impact on the nontarget herbivorous insect, Eupteryx aurata. Expand
Effect of Bt-toxin (Cry1Ac) in Transgenic Cotton on the Adult Longevity of Four Heteropteran Predators
TLDR
Longevity significantly decreased for Orius tristicolor White and Geocoris punctipes Say and no effect was found for Nabis sp. Expand
Tritrophic Choice Experiments with Bt Plants, the Diamondback Moth (Plutella xylostella) and the parasitoid Cotesia plutellae
TLDR
Experiments of parasitoid flight and foraging behaviour presented in this paper showed that adult C. plutellae females do not distinguish between Bt and wildtype oilseed rape plants, and are more attracted to Bt plants damaged by Bt-resistant hosts than by susceptible hosts. Expand
Impact of Genetically Modified Potato Expressing Plant-Derived Insect Resistance Genes on the Predatory Bug Podisus maculiventris (Heteroptera: Pentatomidae)
TLDR
The results indicate that P. maculiventris may suffer some indirect adverse effects from foraging for prey in crops expressing either GNA or CpTI, due to prey being of inferior quality, rather than to direct toxicity of the transgene products themselves. Expand
Influence of transgenic Bacillus thuringiensis corn-fed prey on prey preference of immature Chrysoperla carnea (Neuroptera: Chrysopidae)
Paired-choice assays in a tritrophic system have been carried out to study the influence of trans- genic Bacillus thuringiensis var. kurstaki (Berliner) corn plants on prey preference of the predatorExpand
Parasitoids: Behavioral and Evolutionary Ecology
TLDR
This book synthesizes the work of both schools of parasitoid biology and asks how a consideration of evolutionary biology can help to understand the behavior, ecology, and diversity of the approximately one to two million species of Parasitoids found on earth. Expand
Fitness and feeding are affected in the two‐spotted stinkbug, Perillus bioculatus, by the cysteine proteinase inhibitor, oryzacystatin I
TLDR
Oryzacystatin I (OCI) is a potential insect pest resistance factor currently engineered into a variety of crop plants, including potato Solanum tuberosum, and affected reproduction in Perillus bioculatus is consistent with the use of OCI-sensitive digestive proteinases by this stinkbug. Expand
Potential for the environmental impact of transgenic crops
TLDR
It is found no compelling scientific arguments to demonstrate that GM crops are innately different from non-GM crops, and it is likely that the novelty of some of the products of GM crop improvement will present new challenges and perhaps opportunities to manage particular crops in creative ways. Expand
Towards an ecological systems approach in public research for environmental regulation of transgenic crops
TLDR
The objective of this paper is to identify the types of ecological systems public research to implement effective biosafety controls and the development of improved risk analysis methodologies and protocols should also be a priority. Expand
Coleopteran-specific Cry3Bb Toxin from Transgenic Corn Pollen Does Not Affect the Fitness of a Nontarget Species, Coleomegilla maculata DeGeer (Coleoptera: Coccinellidae)
TLDR
It is concluded that the impact of Cry3Bb-expressing transgenic corn pollen (event MON863) did not detect any effects on the fitness of C. maculata that ingested pollen, and these results do not necessarily apply to other transgenic crops expressing toxins specific to Coleoptera. Expand
