Grain protectants: Current status and prospects for the future
TLDR
Several factors in terms of their potential impact on the use of conventional grain protectants are discussed, including insecticide residues and consumer perceptions, resistance to protectants in major pest species, the direct and indirect costs of insecticides, development and registration of biopesticides, inert dusts, new technologies for fumigation and controlled atmosphere treatments, the expanded use of aeration in management programs, biological controls, and the development of expert systems.

Effectiveness of Spinosad on Four Classes of Wheat Against Five Stored-Product Insects
TLDR
The results suggest spinosad to be a potential grain protectant for R. dominica and P. interpunctella management in stored wheat. Expand
Toxicity of Diatomaceous Earth to Red Flour Beetles and Confused Flour Beetles (Coleoptera: Tenebrionidae): Effects of Temperature and Relative Humidity
  • F. Arthur
  • Biology, Medicine
  • Journal of economic entomology
  • 1 April 2000
TLDR
Mortality of both species after they were held for 1 wk was greater than initial mortality for nearly all exposure intervals at each temperature–humidity combination, indicating delayed toxic effects from exposure to diatomaceous earth. Expand
Insects of Stored Products
Impact of Food Source on Survival of Red Flour Beetles and Confused Flour Beetles (Coleoptera: Tenebrionidae) Exposed to Diatomaceous Earth
  • F. Arthur
  • Biology, Medicine
  • Journal of economic entomology
  • 1 August 2000
TLDR
In all experiments, confused flour beetles were less susceptible to diatomaceous earth than red flour beetles, and survival was negatively related to exposure interval and positively related to relative humidity. Expand
Aerosols and contact insecticides as alternatives to methyl bromide in flour mills, food production facilities, and food warehouses
  • F. Arthur
  • Biology
  • Journal of Pest Science
  • 22 May 2012
TLDR
This review will focus on recent research with contact insecticides and aerosols for controlling stored-product insects in structures and how they can be viewed as options for control to alleviate concerns regarding the phase-out and reduced availability of MB for structural fumigations. Expand
Susceptibility of stored-product beetles on wheat and maize treated with thiamethoxam: effects of concentration, exposure interval, and temperature
TLDR
Results show that thiamethoxam would be an effective protectant of stored maize seed and stored wheat seed and that T. castaneum in untreated maize and untreated wheat was very low compared with the other species. Expand
Survival of Sitophilus oryzae (L.) on wheat treated with diatomaceous earth: impact of biological and environmental parameters on product efficacy
TLDR
Results of these studies show that S. oryzae is susceptible to DE, but survival of exposed insects will depend in part on the temperature and r.h. humidity (or grain moisture content) at which they are exposed. Expand
Evaluation of a new insecticide formulation (F2) as a protectant of stored wheat, maize, and rice☆
TLDR
Results show that the combination insecticidal product F2 was extremely effective on all three commodities at the rate of 100 ppm, as either a dust or slurry, and could be used as a commodity protectant. Expand
Aerosol distribution and efficacy in a commercial food warehouse
TLDR
Results show that the aerosols evaluated in this study could give effective control of some of the major stored‐product insect pests in commercial food storage facilities, and may offer an alternative to fumigation. Expand
