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 ...

Effect of X-ray irradiation on the F1 generation of Sitophilus zeamais Motschulsky and the germination rate of maize grain

Journal of Basic and Applied Zoology, 2021
Background The use of X-ray irradiation in the control of the maize weevil, Sitophilus zeamais Motschulsky (Coleoptera: Curculionidae) infesting stored maize was tested at 60, 70 and 80 KeV as part of the international concerted efforts to save maize ...

Sources of Resistance to the Maize Weevil Sitophilus Zeamais in Tropical Maize

Journal of Agricultural Science, 2012
سوسة الذرة، Sitophilus zeamais (Motschulsky) (غمدية الأجنحة: Curculionidae)، هي من بين آفات التخزين الرئيسية التي تعزز انعدام الأمن الغذائي بين مزارعي الذرة. تعتبر المصادر الجديدة لمقاومة سوسة الذرة حاسمة في برنامج التكاثر الناجح لمعالجة تلف الحبوب بسبب آفات ما بعد الحصاد. كان الهدف من الدراسة هو تقييم المقاومة في الأنماط الجينية للذرة تجاه سوسة الذرة،

New discovery of the oldest maize weevils in the world from Jomon potteries, Japan [PDF]

, 2010
The maize weevil (_Sitophilus zeamais_) and rice weevil (_Sitophilus oryzae_) are two of the most damaging insects for stored grains, and are characteristic species of ancient Japan. Both species and the granary weevil (_Sitophilus granarius_) are common

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 ...

Screening of Promising Maize Genotypes Against Maize Weevil (Sitophilus Zeamais Motschulky) in Storage Condition [PDF]

, 2017
The maize weevil (Sitophilus zeamais Motschulsky) is a serious pest of economic importance in stored grains. It causes major damage to stored maize grain thereby reducing its weight, quality and germination.

Edges as ecological filters: Asymmetrical orientation‐specific arthropod activity across forest boundaries

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.

Toxicity and synergism of the essential oil of Piper aduncum L. in populations of Sitophilus zeamais(Coleoptera: Curculionidae)

Pesquisa Agropecuária Tropical, 2023
Researches on the use of essential oil of Piper aduncum L. (EOPA) as a synergist in stored grain pests are still incipient. This study aimed to determine the toxicity of deltamethrin and EOPA, as well as to study the effect of the binary mixture of EOPA +
