Spatial distribution and losses by grain destroying insects in transgenic corn expressing the toxin Cry1Ab. [PDF]

PLoS ONE, 2018
Insect pests are one of the factors that most impact plant yield. The magnitude of the losses and the spatiotemporal pest distribution in crops is a result of their interactions with the environment.

Effects of carbon dioxide on the searching behaviour of the root-feeding clover weevil Sitona lepidus (Coleoptera: Curculionidae) [PDF]

, 2006
The respiratory emission of CO2 from roots is frequently proposed as an attractant that allows soil-dwelling insects to locate host plant roots, but this role has recently become less certain.

Odour-mediated orientation of beetles is influenced by age, sex and morph [PDF]

, 2012
The behaviour of insects is dictated by a combination of factors and may vary considerably between individuals, but small insects are often considered en masse and thus these differences can be overlooked.

Spatial Patterns of Aflatoxin Levels in Relation to Ear-Feeding Insect Damage in Pre-Harvest Corn

Toxins, 2011
Key impediments to increased corn yield and quality in the southeastern US coastal plain region are damage by ear-feeding insects and aflatoxin contamination caused by infection of Aspergillus flavus. Key ear-feeding insects are corn earworm, Helicoverpa

The Arkansas Laboratory Strain of the Maize Weevil [PDF]

Bulletin of the Entomological Society of America, 1975
The parent insects of the Arkansas laboratory strain of Sitophilus zeamais Motschulsky were collected by the author from a bin of corn located on a farm near Stuttgart, Ark., in 1955. The strain was retained and reared as a separate culture because the insects were darker and larger than the laboratory strain of “rice” weevils.
