Combining Ability for Maize Weevil Preference of Maize Grain

Crop Science, 1995
Maize weevil (Sitophilus zeamais Motschulsky) can cause severe grain damage in maize (Zea mays L.). Knowledge of inheritance of weevils' preference would be helpful in designing breeding strategies to develop more tolerant/resistant cultivars. This study was conducted to estimate general (GCA) and specific combining ability (SCA) for weevil preference ...

The chemical identification of the rice weevil and maize weevil aggregation pheromone

Tetrahedron Letters, 1984
Abstract (R*,S*)-4-methyl-s-hydroxy-3-heptanone is identified as the major component of the aggregation pheromone of the rice weevil ( sitophilus oryzae L.) and the maize weevil ( S. zeamais Motsch.).

Damage of Maize Borer and Maize Weevil on the Yield of Transgenic Phytase Maize

Agronomy Journal, 2015
The recent Chinese government approval of transgenic phytase maize for field experimentation is vital for its development of biotech maize for improved maize production. Phytase maize can potentially improve the efficiency of feed utilization by livestock and reduce environmental pollution from animal manure.

Evaluation of stirring to suppress weevils in stored maize

Journal of Stored Products Research, 2021
Abstract The maize weevil (Sitophilus zeamais Motschulsky) is found throughout the world and is among the most destructive pests of stored grain and grain products. Maize weevil suppression is difficult and chemical insecticides are frequently employed.

Divergent Selection for Resistance to Maize Weevil in Six Maize Populations

Crop Science, 2003
Maize weevil (Sitophilus zeamais Motschulsky) is an important pest of maize (Zea mays L.) in the tropics, causing serious losses for many resource‐poor farmers who store grain on‐farm for use as food and seed. This study evaluated whether weevil resistance of six maize populations could be divergently changed by S1 and S2 selection, and assessed the ...

Mapping of QTL Associated with Maize Weevil Resistance in Tropical Maize

Crop Science, 2009
ABSTRACTThe maize weevil (MW), Sitophilus zeamais (Motsch.), is an important pest of stored maize (Zea mays L.) in tropical areas. Quantitative trait loci (QTL) associated with MW resistance were analyzed. A total of 163 F2 progeny derived from the cross CML290 (susceptible) × Muneng‐8128 C0 HC1‐18‐2‐1‐1 (resistant), were genotyped with 151 molecular ...

Inheritance of Maize Weevil Resistance in Maize¹

Crop Science, 1975
Ten, eight‐line sets of dent maize inbreds (Zea mays L.) were tested for seed resistance to maize weevil (Sitophilus zeamais Motschulsky) in a design II experiment. The genetic variability was evaluated for maternal, cytoplasmic, and endosperm genotype sources.

Genetic mapping of QTL for maize weevil resistance in a RIL population of tropical maize

Theoretical and Applied Genetics, 2014
A tropical RIL maize population was subjected to phenotypic and genotypic analysis for maize weevil resistance during four seasons, and three main genomic areas were detected as main QTLs. The maize weevil (Sitophilus zeamais) (MW) is a common and important pest of stored maize (Zea mays) worldwide, especially in tropical areas. Quantitative trait loci

Resistance of Maize Landraces to the Maize Weevil Sitophilus zeamais Motsch. (Coleoptera: Curculionidae)

Neotropical Entomology, 2012
The maize weevil Sitophilus zeamais Motsch. is an important pest of maize that attacks the grain both in the field and during storage. The damage caused by the maize weevil S. zeamais on maize landraces, Amarelo Antigo, Asteca, Caiano, Carioca, and Ferrinho, was evaluated by no-choice tests under laboratory conditions.

Factors contributing to resistance of exotic maize populations to maize weevil,Sitophilus zeamais

Journal of Chemical Ecology, 1987
Factors contributing to resistance of maize to infestation by the corn weevilSitophilus zeamais were investigated in four populations of indigenous and improved maize from Belize. Resistance was related to the antifeedant properties of grain as well as sugar content and mechanical hardness.
