Summary: The study found that diatomaceous earth showed stable control efficacy on Tribolium castaneum, while pirimiphos-methyl had varied effectiveness at different concentrations. Sitophilus oryzae populations were more susceptible to both insecticides. The results indicate the importance of preliminary screening to ensure the success of resistance management programs.

Summary: This study compared the susceptibility to phosphine in 15 populations of lesser grain borer (Rhyzopertha dominica) collected from grain storage godowns across India. The results showed a high level of resistance to phosphine in R. dominica collected from northern India compared to those from northeastern regions. The activity of antioxidant enzymes differed significantly among field populations exposed to phosphine, with peroxidase and superoxide dismutase activities positively associated with resistance, while catalase activity had a negative association with resistance.

Summary: Phosphine resistance was evaluated in 23 populations of Tribolium castaneum from 10 different countries. High levels of resistance were found in populations from Brazil, Serbia, and Spain. Eight populations showed no survival after 7 days post exposure.

Summary: IRPs have antifungal, repellent, and fumigant properties, and can repel red flour beetles. The active components present in IRPs were still found after a storage period of 35 days.

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: Insect infestation poses a significant threat to global food security, and a new technique called Direct Analysis in Real Time-High-Resolution Mass Spectrometry was used to differentiate infested and uninfested flour samples through statistical analysis. This technique identified specific compounds responsible for the infestation, potentially leading to a rapid method for testing flour and other grains for insect infestation.

Summary: This study evaluated the fumigant toxicity and biochemical effects of 23 selected essential oils against Tribolium castaneum. The results showed that essential oils with higher fumigant potential tended to have greater chemical diversity, leading to better insecticidal effects. Some essential oils also exhibited strong inhibitory effects on specific enzymes, making them promising candidates for biological control of T. castaneum.

Summary: This study demonstrated that the lesser grain borer is attracted to traps baited with a specific aggregation pheromone, which is more attractive than natural stored wheat. There is a significant correlation between temperature and the captures of the lesser grain borer, with peak captures occurring during the warmest months.

Summary: Insect populations sampled from Greek warehouses and silos showed different patterns of tolerance to widely used insecticides, indicating possible resistance. These findings emphasize the need to revise current pest management practices in order to reduce control failures.

Summary: This study conducted a comprehensive review of the literature on phosphine resistance published from 1975 to 2021. The findings showed that phosphine resistance is prevalent among key pest species of stored products and is increasing in both levels and prevalence. The lesser grain borer, rice weevil, and red flour beetle were the most problematic species in terms of resistance. Reports and monitoring of phosphine resistance are mainly focused on four countries: Australia, Brazil, Greece, and the US.

Summary: The study explored the repellency behavior of citronellal-derived compounds on red flour beetles, finding that TcTRPA1 and odorant receptor co-receptor played a significant role in mediating this behavior, suggesting potential implications for insect repellents involving citronella oil.

Summary: Stored product pests cause significant losses to agricultural products every year. The use of fungal entomopathogens provides a promising alternative to chemical control methods. In our study, new wild strains of entomopathogenic fungi were tested on storage beetles in laboratory bioassays, showing remarkable mortality rates. Further research is needed to discover new strains and develop practical application methods.

Summary: The study focuses on Tribolium castaneum, a model beetle, and its positive single-stranded RNA virus, Tribolium castaneum iflavirus (TcIV). It found that TcIV is prevalent among different laboratory cultures, strains, and the same strain maintained in different laboratories, as well as in the Tribolium cell line TcA. The study also supports transovarial transmissions and the virus' prevalence in the nervous system, offering an opportunity to study the interaction between the virus and the immune system in this model beetle species.

Summary: The study reveals that sensory neurons in the larval antennae of the red flour beetle are reused in the adult stage, while the structure of the antennal lobe undergoes transformation. The formation of adult glomeruli in the antennal lobe during mid-metamorphosis is a common feature among different insect species, although the role of Orco in development may vary.

Summary: A study identified 883 miRNAs in Tribolium castaneum, with 102 miRNAs exhibiting stage-specific expression patterns. Knockdown of five differentially expressed miRNAs led to defects in metamorphosis and wing development. This study provides important insights into the roles of miRNAs in insect growth and development.
