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.

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 ...

Determining Terminal Velocities of Selected Insects and Substitute Materials to Develop Future Test Procedures for Insect‐Friendly Mowing Technology

Journal of Applied Entomology, EarlyView.
ABSTRACT Agricultural grasslands are vital habitats for insects that provide key ecosystem services. However, conventional rotary mowers are proposed to cause significant insect mortality due to the high rotational speed of their blades and the resulting airflow.

Evaluation of Hermetic Maize Storage for Smallholder Farmers [PDF]

, 2014
Maize is an important crop for many smallholder farmers in the world. Maize weevils (Sitophilus zeamais) cause a significant loss in quality and quantity during maize storage in tropical regions.

Loss‐of‐Function Mutation in CER2‐LIKE1 Reduced Accumulation of Cuticular Wax and Susceptibility to Thrips in Welsh Onion

Plant Biotechnology Journal, EarlyView.
ABSTRACT Cuticular waxes can form a hydrophobic barrier on aerial plant surfaces, which is essential for mediating plant‐environment interactions by providing protection against both biotic and abiotic stresses. In this study, a cuticular wax mutant (gl) was identified and characterised in Welsh onion (Allium fistulosum L.), exhibiting a functional ...

Rhizobia–Bean Symbiosis Increases Root Herbivore Attraction and Growth via Volatile Signals and Enhanced Nutrition

Plant, Cell &Environment, EarlyView.
ABSTRACT The symbiosis between nitrogen‐fixing rhizobia and plants is considered mutually beneficial, yet its indirect effects on other organisms remain understudied. We examined how rhizobia symbiosis in Phaseolus vulgaris influences the behaviour and performance of Diabrotica balteata larvae. Specifically, we tested larval preference for nodulated (R+

Competition of three species of Sitophilus on rice and maize. [PDF]

PLoS ONE, 2017
Laboratory tests were carried out in order to examine competition among three congeneric species on rice and maize: the granary weevil, Sitophilus granarius, the rice weevil, Sitophilus oryzae and the maize weevil, Sitophilus zeamais. For this purpose, a

Comparative Bioactivity of Bamboo Leaf Ash and Bularafa Diatomaceous Earth against Maize Weevil (Sitophilus zeamais Motschulsky)

Journal of Applied Sciences and Environmental Management, 2022
Maize is one of the major staple foods in Sub-Saharan Africa and there is serious loss in maize storage due to insect damage. This study compared the bioactivity of Bamboo Leaf Ash (BLA) and Bularafa Diatomaceous Earth (BDE) against Maize Weevil ...

A Volatile Cue From a Specialist Herbivore Primes Gene Expression Against Biotic Stress in Tall Goldenrod (Solidago altissima L.)

Plant, Cell &Environment, EarlyView.
ABSTRACT Insect‐derived molecular cues can prime plant defences against herbivore attack. The genes that are sensitive to priming, and how their expression changes on the scale of days, have not been fully resolved. Moreover, priming may affect interactions with insects that are not the source of the priming cue.

Reproductive Status of Boll Weevils During Season and Off‐Season of Cotton in the Cerrado of Brazil

Entomologia Experimentalis et Applicata, Volume 174, Issue 2, Page 113-122, February 2026.
Cotton boll weevils were monitored continuously and counted weekly over two agricultural years in the Brazilian Cerrado. The survey resulted in a total of 94 519 adults captured in approximately similar percentages of females and males during both the growing and off‐seasons.
