Detection of Phosphine Resistance in Field Populations of Four Key Stored-Grain Insect Pests in Pakistan

Insects, 2021
In Pakistan, the control of stored-product insect pests mainly relies on the use of phosphine gas along with other control tactics. The aim of this study was to determine the level of phosphine resistance among ten differently located populations of the ...

Controlling insects in stored grain by disturbing the grain

Julius-Kühn-Archiv, 2018
Insects can cause damage to stored grain, especially on smallholder farms in the tropics. Sitophilus zeamais (maize weevil, MW) and Rhyzopertha dominica (lesser grain borer, LGB) are often involved. Our objective was to determine, by four experiments, if

A silo for suppressing the population of Rhyzopertha dominica (F.) (Coleoptera, Bostrichidae) in stored wheat

Cogent Food & Agriculture, 2016
The present study showed how the construction of a grain silo prototype can be used to increase the mortality rate of the lesser grain borer, Rhyzopertha dominica (F.). The silo prototype is a bin of small dimensions, adequate for laboratory environments,

Post-Harvest Insect Pests and Their Management Practices for Major Food and Export Crops in East Africa: An Ethiopian Case Study

Insects, 2022
Ethiopian subsistence farmers traditionally store their grain harvests, leaving them open to storage pests and fungi that can cause contamination of major staple crops.

Lesser Grain Borers,Rhyzopertha dominica, Select Rough Rice Kernels with Cracked Hulls for Reproduction [PDF]

Journal of Insect Science, 2012
Tests were conducted to determine whether the lesser grain borer, Rhyzopertha dominica (F.) (Coleoptera: Bostrychidae), selects rough rice (Oryza sativa L. (Poales: Poaceae)) kernels with cracked hulls for reproduction when these kernels are mixed with intact kernels.

Responses to colour and host odour cues in three cereal pest species, in the context of ecology and control [PDF]

, 2015
Many insects show a greater attraction to multimodal cues, e.g. odour and colour combined, than to either cue alone. Despite the potential to apply the knowledge to improve control strategies, studies of multiple stimuli have not been undertaken for ...

Novel bacteriocyte-associated pleomorphic symbiont of the grain pest beetle Rhyzopertha dominica (Coleoptera: Bostrichidae)

Zoological Letters, 2017
Background The lesser grain borer Rhyzopertha dominica (Coleoptera: Bostrichidae) is a stored-product pest beetle. Early histological studies dating back to 1930s have reported that R.

Testing wheat for internal infesting insects with an electrically conductive roller mill

Julius-Kühn-Archiv, 2018
Although grain is always inspected for adult insects and insect damaged kernels upon shipping and receiving, immature insects living inside the kernels of grain cannot be readily detected.

Using elemental profiling to determine intrinsic markers to track the dispersal of Prostephanus truncatus, a pest of stored grain with alternative natural hosts [PDF]

, 2016
"Detecting sources of insects attacking grain stores can help to develop more effective pest management models. This study considers combinations of chemical elements as intrinsic markers for tracing resource-use by Prostephanus truncatus (Horn ...
