Spectral Characterization of the Life Stages and Physiological Responses of Diatraea saccharalis Fabricius (Lepidoptera: Crambidae) Larvae Parasitized by Cotesia flavipes Cameron (Hymenoptera: Braconidae)

Entomologia Experimentalis et Applicata, EarlyView.
Hyperspectral proximal sensing was used to characterize the life stages and physiological responses of Diatraea saccharalis and to detect parasitism by Cotesia flavipes. Distinct spectral signatures differentiated eggs, larval instars, pupae, and adults, as well as live, dead, and parasitized larvae.

Forage Plant Host and Early Feeding Choices Affect Spodoptera litura Feeding, Development and Egg‐Laying

Entomologia Experimentalis et Applicata, EarlyView.
We assessed Spodoptera litura (Lepidoptera: Noctuidae) performance on five common pasture plant species. Larvae consumed more dock, plantain and chicory per day than red or white clover, but with lower conversion efficiencies. Feeding on red clover reduced weights and egg laying, and lengthened development times compared with plantain.

Responses of Fruit Flies (Diptera: Tephritidae) to Protein Bait Applied at Different Densities

Journal of Applied Entomology, EarlyView.
ABSTRACT The effectiveness of odour‐based lures for insects is related to their active space, the air volume around an odour source in which an insect will detect and move towards it. This principle applies to protein baits laced with toxicants that are used as either sprays or stations to suppress pest fruit fly populations.

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

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+

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 ...

Identification of Host Kairomones from Maize, Zea mays, for the Maize Weevil, Sitophilus zeamais

Journal of Chemical Ecology, 2012
The maize weevil, Sitophilus zeamais, is an economically important pest of stored grains in tropical and subtropical regions of the world. The behavioral responses of adult S. zeamais to volatile organic compounds (VOCs) from maize seeds, Zea mays, were studied to identify semiochemicals used in host location and provide potential tools for managing ...

Biological Pesticides as Viable Alternative to Synthetic Pesticides for Sustainable Agriculture and Nutrition: A Systematic Review

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 2, June 2026.
ABSTRACT The overuse of synthetic pesticides in agriculture has raised significant environmental and health concerns. Biopesticides have emerged as viable, environmentally compatible alternatives. However, recent comprehensive reviews integrating all biopesticide categories and emphasizing their contribution to synthetic‐pesticide‐free and health‐safe ...

Loss Assessment of Stored Maize at Different Storage Durations and Maize Weevil Densities

European Journal of Nutrition & Food Safety, 2021
Aims: The extent of stored grain losses depends on varieties and duration of storage, and  most of the quantitative losses are attributed to insect pest infestations. The study was  conducted to determine the damage caused by Sitophilus zeamais on maize stored at different durations. Methodology: Sitophilus zeamais at four varying population ...

Effectiveness of botanical preparations for the control of rice weevil (Sitophilus oryzae) during rice seed storage and their impact on the rice seed viability : a thesis presented in partial fulfilment of the requirements for the degree of Master of Applied Science in Seed Technology at Massey University, Palmerston North, New Zealand [PDF]

, 2001
Food security and the maintenance of seed quality from harvest to planting are key issues for peasant farmers. In Sierra Leone, up to 28% of rice seed can be damaged by rice weevil in the six months storage period.
