Cry1Ab protein levels in phytophagous insects feeding on transgenic corn: implications for secondary exposure risk assessment
The level ofCry1Ab in insects feeding on sources containing the Cry1Ab protein was uniformly low but varied with insect species as well as food source, and secondary exposure risk assessment for transgenic Bt crops is discussed.
Occurrence of Emerald Ash Borer (Coleoptera: Buprestidae) and Biotic Factors Affecting Its Immature Stages in the Russian Far East
ABSTRACT Field surveys were conducted from 2008 to 2011 in the Khabarovsk and Vladivostok regions of Russia to investigate the occurrence of emerald ash borer, Agrilus planipennis Fairmaire, and…
Population responses of hymenopteran parasitoids to the emerald ash borer (Coleoptera: Buprestidae) in recently invaded areas in north central United States
Populations of hymenopteran parasitoids associated with larval stages of the invasive emerald ash borer (EAB) Agrilus planipennis Fairmaire were surveyed in 2009 and 2010 in the recently invaded areas in north central United States (Michigan).

Results demonstrate that T. planipennisi is established in southern Michigan and that its populations are increasing and expanding, and suggest that it will likely play a critical role in suppressing emerald ash borer populations in Michigan.

There were no significant differences in mortality rates because of parasitism between parasitoid-release and control plots, and T. planipennisi was detected in each of the three release sites by the end of the study but was not detected in the experimental cohorts or associated wild larvae in any of theThree control plots.
Evaluation of dietary effects of transgenic corn pollen expressing Cry3Bb1 protein on a non‐target ladybird beetle, Coleomegilla maculata
It is demonstrated that when offered at 50% by weight of the dietary component, transgenic corn (MON 863) pollen expressing Cry3Bb1 protein had no measurable negative effect on the survival and development of C. maculata larvae to pupation and adulthood nor any adverse effect on adult survival and reproductive capacity.
Genome of the Asian longhorned beetle (Anoplophora glabripennis), a globally significant invasive species, reveals key functional and evolutionary innovations at the beetle–plant interface
Amplification and functional divergence of genes associated with specialized feeding on plants, including genes originally obtained via horizontal gene transfer from fungi and bacteria, contributed to the addition, expansion, and enhancement of the metabolic repertoire of the Asian longhorned beetle and to a lesser degree, other phytophagous insects.
A Meta-Analysis of Effects of Bt Crops on Honey Bees (Hymenoptera: Apidae)
The results show that Bt Cry proteins used in genetically modified crops commercialized for control of lepidopteran and coleopteran pests do not negatively affect the survival of either honey bee larvae or adults in laboratory settings.
Extrapolating non-target risk of Bt crops from laboratory to field
The assumption that laboratory studies of transgenic insecticidal crops show effects that are either consistent with, or more conservative than, those found in field studies is supported, with the important caveat that laboratory Studies should explore all ecologically relevant routes of exposure.
