Summary: This review discusses insect movement, detection and tracing methods in stored grain bulks, emphasizing factors influencing insect mobility and model equations for predicting insect movement and spatial distribution. Practical difficulties and challenges associated with studies of insect movement under multiple gradients are also discussed. Directions for future research in insect movement detection using emerging cost-effective technologies are presented.

Summary: The effectiveness of ZeroFly((R)) Hermetic and Purdue Improved Crop Storage bags in controlling insect pests and mycotoxin levels in yellow maize was compared to standard polypropylene bags. The study showed that ZeroFly((R)) Hermetic and Purdue Improved Crop Storage bags protected yellow maize against insect pests and kept aflatoxin and fumonisin levels within recommended thresholds.

Summary: The study evaluated the effectiveness of a range of insecticides for the control of the larger grain borer. Inert dusts and residual insecticides were tested against the adults of the species. The results showed that the inert dusts had low mortality rates and failed to suppress the progeny production, while the residual insecticides had high mortality rates and significantly suppressed progeny production.

Summary: The present study aimed to evaluate the potential of major storage insect species to grow and reproduce on insect meals based on the lesser mealworm larvae. Results showed that six out of thirteen examined insect species were able to infest pure lesser mealworm meals, with the storage beetle Trogoderma granarium showing the highest rate of increase. Further research is needed to improve production and storage facilities, detection and estimation methods, and minimize insect infestations without negative effects on farmed insects, especially considering the projected increase in insect-based product production globally.

Summary: Parasitoid wasps are effective biological control agents for arthropod pests in agricultural and forest ecosystems, but combining them with synthetic chemical pesticides poses challenges. While immediate effects of pesticides on parasitoid communities are observed, long-term recovery is possible. Further research is needed to understand the nature of parasitoid wasp recovery in stored-product facilities to enhance biological control effectiveness.

Summary: This study compared the effect of different combinations of traps and attractants on stored-product insects. The most abundant species were Indian meal moth, red flour beetle, and cigarette beetle. While there were differences in specific species, all combinations provided similar information on population dynamics. Dome traps baited with oil or gel were found to be the most sensitive.

Summary: Smallholder maize farmers in Ghana face challenges of limited access to efficient drying systems, leading to high post-harvest losses. A study evaluating a portable column dryer showed promising technical and economic performance in reducing moisture content of maize and providing cost-effective drying services for farmers in the region.

Summary: Bioassays were conducted to evaluate the insecticidal efficacy of thiamethoxam on seven important beetle species at various concentrations. Results demonstrated that as the concentration of the insecticide increased, adult mortality also increased while progeny production decreased. Among the seven insects, Prostephanus truncatus showed the highest sensitivity to thiamethoxam, suggesting that a rate of 10 ppm for 14 days could effectively control all insects and their progeny.

Summary: This study evaluated the efficacy of A. oleracea extracts in controlling arthropod pests attacking stored foodstuffs. The n-hexane extract was more effective than the methanol extract against most species and stages. The research highlights the importance of targeting susceptible species and developmental stages when using N-alkylamides-rich A. oleracea extracts as grain protectants.

Summary: The study found that leaf stripping in maize-livestock farming systems in northern Ghana can improve yield and feed quality. Different types of maize showed varying responses to leaf stripping in terms of leaf biomass, stover, and cob width in different regions, but leaf stripping did not significantly affect grain yield and crude protein content of maize leaves.

Summary: Stored-product insects, such as Sitophilus oryzae, Rhyzopertha dominica, and Tribolium castaneum, are adapted to dry conditions and a diet of grains. Deltamethrin emulsifiable concentrate has been found to be effective in controlling these insects when sprayed on nonporous surfaces or directly on the insects, but less effective as a residual insecticide on porous surfaces. A concentration of 0.2-2.0 ppm of deltamethrin was necessary for complete mortality of the insects.

Summary: By investigating trait preferences of maize value chain actors in northern Ghana, this research provides empirical evidence to guide research strategies for maize improvement. The study reveals overlapping preferences among farmers and other actors, highlighting their emphasis on grain quality, stress tolerance, and yield when choosing maize varieties. The participatory approach used in this study identified key traits desired by different actors, which can be used by breeders to develop varieties favored by all value chain actors in the region.

Summary: Insect infestation during the storage of cowpea is a major challenge for smallholder farmers in sub-Saharan Africa. A study in Northern Ghana found that most farmers prefer using PICS technology to store cowpea due to its effectiveness in reducing pesticide-related health risks.

Summary: This study estimated the discriminating doses of phosphine for eight psocid species and found that Liposcelis entomophila and L. decolor were the most tolerant species. The discriminating doses can be used for detection of phosphine resistance and estimation of resistance frequencies in field-collected populations of the investigated psocid species.

Summary: Predatory mites have diverse ecological mechanisms to control pest population density, but their effectiveness varies. This study examined the numerical responses of two predatory mites, C. eruditus and C. malaccensis, to the prey L. decolor. The oviposition rate, oviposition efficiency, and efficiency of conversion of ingested (ECI) food resources were assessed. The results showed a negative correlation between oviposition rates and prey densities for C. eruditus, while C. malaccensis had a positive correlation. ECI decreased with increasing prey density, but C. malaccensis was more efficient in utilizing prey biomass. Further assessment is recommended before using these predatory mites for stored-product insect pest management in the United States.

Summary: This study evaluated the efficiency of two predatory mite species, Cheyletus eruditus and Cheyletus malaccensis, in managing the phosphine-tolerant stored product psocid pest Liposcelis decolor. The results showed that C. eruditus performed better, with higher consumption rate and searching efficiency compared to C. malaccensis. However, further studies are needed to validate their efficiency and compatibility with other management strategies in field trials.

Summary: This study examined the efficacy of predatory mites Cheyletus eruditus and Cheyletus malaccensis in managing Liposcelis decolor. The results showed that both predatory mites suppressed the pest population and increased their own progeny. Despite limitations in low relative humidity levels, these predatory mites have potential for psocid management.
