Impact of Bt corn pollen on monarch butterfly populations: A risk assessment
TLDR
The impact of Bt corn pollen from current commercial hybrids on monarch butterfly populations is negligible, according to a 2-year study by scientists in several states and in Canada.
PEST STATUS OF THE BROWN MARMORATED STINK BUG, HALyOMORPHA HALyS IN THE USA
TLDR
The current pest status and strategies being developed to manage brown marmorated stink bug in the USA are summarized.
Biology, Ecology, and Management of Brown Marmorated Stink Bug (Hemiptera: Pentatomidae)
TLDR
Pesticide applications, including broad-spectrum insecticides, have increased in response to H. halys infestations, potentially negatively influencing populations of beneficial arthropods and increasing secondary pest outbreaks.
Colorado Potato Beetle Resistance to Insecticides
TLDR
Still limited understanding of beetle biology, its flexible life history, and grower reluctance to adopt some of the resistance management techniques create impediments to successful resistance management.
Corn pollen deposition on milkweeds in and near cornfields
TLDR
The density of corn pollen on leaves of milkweed plants inside and outside of cornfields was measured to obtain a representative picture of naturally occurring pollen densities to provide a perspective for laboratory and field studies of monarch larvae feeding on milkweed leaves with Bt corn pollen.
Temporal and spatial overlap between monarch larvae and corn pollen
TLDR
It is found that monarchs use milkweed in cornfields throughout their breeding season, and that per plant densities are as high or higher in agricultural habitats as in nonagricultural habitats, suggesting that agricultural practices such as weed control and foliar insecticide use could have large impacts on monarch populations.
Pesticide exposure in honey bees results in increased levels of the gut pathogen Nosema
TLDR
An increase in pathogen growth within individual bees reared in colonies exposed to one of the most widely used pesticides worldwide, imidacloprid, at below levels considered harmful to bees is clearly demonstrated.

TLDR
Levels of neonicotinoid residues in pollen and nectar from a pumpkin crop treated with formulated products containing imidacloprid, dinotefuran, and thiamethoxam using different timings and application methods were measured.
Assessing the impact of Cry1Ab-expressing corn pollen on monarch butterfly larvae in field studies
TLDR
The effects of Bt11 and Mon810 pollen on the survivorship of larvae feeding 14 to 22 days on milkweeds in fields were negligible and survivorship and weight gain were drastically reduced in non-Bt fields treated with λ-cyhalothrin.
Effects on Monarch Butterfly Larvae (Lepidoptera: Danaidae) After Continuous Exposure to Cry1Ab-Expressing Corn During Anthesis
TLDR
Results indicate that 23.7% fewer larvae exposed to these levels of Bt pollen during anthesis reached the adult stage, and exposure prolonged the developmental time of larvae by 1.8 d and reduced the weights of both pupae and adults by 5.5%.
