Summary: The study explored the potential of Trogoderma granarium to displace Trogoderma inclusum in a stored product setting through direct competition experiments. It was found that T. inclusum outproduced T. granarium on all commodities and temperatures, but the proportion of T. granarium was higher at 32 degrees C. T. granarium performed best on wheat, while rice was optimal for T. inclusum. The findings suggest that the larvae of T. granarium pose a real threat to establish populations within grain storage infrastructure where T. inclusum is common.

Summary: The khapra beetle is an important quarantine pest, and new treatment options are needed for eradicating isolated populations. A combination of sulfuryl fluoride and propylene oxide has been evaluated for effectiveness in controlling khapra beetles at different stages. Combination treatments using both products have shown enhanced treatment efficacy over each product alone against all life stages of khapra beetle.

Summary: This study investigated the effects of long-lasting insecticide treated netting (LLIN) on khapra beetle larvae. The results showed that LLIN did not have a significant impact on adult emergence of larvae, but there were interacting effects of untreated netting and LLIN relating to thigmotaxis and anemotaxis.

Summary: This study evaluated the control potential of six native entomopathogenic fungi against three major stored insect pests. The results showed that Metarhizium flavoviride caused the highest mortality and progeny suppression, while Aspergillus nidulans, Aspergillus fumigatus, and Penicillium citrinum had the lowest effects. Rhyzopertha dominica was the most susceptible species to all fungal isolates. Further research is recommended to assess the control potential of these fungi under storage conditions and explore more virulent strains.

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 demonstrated that previous captures of adults do not negatively affect captures of new live adults and may enhance captures in some cases. T. variabile showed a stronger response to traps compared with T. granarium.

Summary: Due to the complexity of controlled atmospheres in agro-commodities protection, there is a lack of scientific documentation on the practical usage of inert gases. This study evaluated the effectiveness of hypoxic and anoxic nitrogen atmospheres in controlling two major pests in grain storage, Sitophilus granarius and Callosobruchus chinensis, under laboratory and field conditions.

Summary: The research explores using irradiation, modified atmosphere, and their combinations for disinfection of the khapra beetle, finding late-stage larvae to be the most tolerant stage. Through the synergistic effects of ionizing radiation and MA treatments, exposure times were reduced by up to 60% compared to MA treatment alone. The results suggest that the MA-irradiation combination treatment provides high-level quarantine security and can be used in international transportation for pest disinfestation.

Summary: The article discusses the Khapra beetle, a major insect pest in stored products in hot and dry regions. It highlights the wide range of hosts these beetles feed on, the economic impact on countries harboring this species, and the challenges in identifying and controlling it. The article also provides information on identification, losses, and management strategies to assist farmers and bio-security experts in controlling this species in storage and quarantine.

Summary: This study evaluated the efficacy of the entomopathogenic nematode Steinernema carpocapsae and the entomopathogenic fungus Beauveria bassiana in managing stored-grain pests. Single application of S. carpocapsae caused higher mortality rates compared to B. bassiana for all six pest species. The combined treatment of EPF and EPN resulted in even higher mortality rates. The study demonstrates the potential of specific combinations of EPF and EPN as effective natural enemies against stored-grain pests.

Summary: This study evaluated the efficacy of ozone against different life stages of the Khapra beetle and found that a concentration of 1200 ppmv provided effective protection for stored wheat without significantly affecting its composition.

Summary: In this study, the insecticidal effect of Carifend(R) and Carifend-like nets with different concentrations of alpha-cypermethrin was examined. The results showed that even nets with a lower concentration (10 mg m(-2)) were effective in controlling the stored tobacco insect pests. Therefore, Carifend(R) and similar nets can be used as an alternative method for insect control.

Summary: In this study, binary mixtures of organophosphorus insecticides and inert dusts were tested, and it was found that specific mixtures had high mortality rates for the larvae of Trogoderma granarium, as well as effectively controlling their reproduction. This is important for the management of this destructive invasive insect.

Summary: This study examined the effectiveness of the insecticide spinetoram and the fungi Beauveria bassiana as wheat protectants against various grain pests. The combination of B. bassiana and spinetoram exhibited the highest mortality rates and reduced progeny production of the pests. This combination may be an efficient tool for integrated pest management strategies during long storage periods.

Summary: The use of NGS in studying the gut microbiome of insects may be confounded by co-occurring infections of Wolbachia bacteria in the host cells. In infected spotted-wing drosophila, the microbiome was predominantly dominated by Wolbachia, with lower bacterial richness and diversity compared to uninfected flies.
