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.

Comparative resistance of improved maize genotypes and landraces to maize weevil
African Crop Science Journal, 2010 A comparative study of maize (Zea mays L.) weevil (Sitophilus zeamais Motsch.) resistance in selected landraces and improved genotypes of maize, was conducted through a field experiment and laboratory assays. The maize grain characteristics that confer resistance to the maize weevil, Sitophilus zeamais Motschulsky, namely; grain hardness, weight and ...

Breeding for multi‐stress resilience in crops: Myth or possibility?
PLANTS, PEOPLE, PLANET, EarlyView.Climate change threatens millions of farmers worldwide by exposing crops to multiple concurrent or sequential environmental stresses such as drought, heat, waterlogging, and diseases. Although crops have long been selected under naturally occurring multi‐stress conditions, breeding pipelines largely focus on optimal or single‐stress environments ...

Insect Science, EarlyView.Moderate retention forestry creates structurally sharp forest edges that act as ecological filters, shaping orientation‐specific activity of ground‐dwelling arthropods. Using drift‐fence pitfall traps, we show that activity aligned with ecotones is more frequent than activity across forest–clearcut boundaries, particularly among detritivores.
