“…It seems that the efficacy of a partial treatment is condition-dependent and is influenced by the extent of grain coverage, pesticide compounds and formulation, species of storage pests, and the sensitivity (resistance/tolerance) of the particular population [ 212 , 245 ]. For instance, Subramanyam et al [ 246 ] claimed that complete control of R. dominica adults can be achieved if more than 50% of the kernels receive spinosad treatment. Daglish and Nayak [ 238 ] warned that uneven application may reduce the efficacy of s-methoprene in non-susceptible R. dominica populations.…”

“…The reason for this is, as explained by Daglish et al [ 40 ], that uneven distribution of pesticide protectants may lead to the occurrence of zones within the grain bulks that are under-dosed or even untreated areas, which allow insect colonization and progeny production. The necessity of even protectant distribution is not only to ensure biological efficacy against pests [ 238 , 246 ] but also to prevent local exceedances of insecticide maximum residue levels (MRLs). To reduce the risk of residue accumulation, it has even been suggested to incorporate insecticides such as chlorpyrifos-methyl in a xanthan gum biopolymer [ 249 ].…”

The selective application of insecticides is one of the cornerstones of integrated pest management (IPM) and management strategies for pest resistance to insecticides. The present work provides a comprehensive overview of the traditional and new methods for the application of gas, liquid, gel, and solid physical insecticide formulations to control stored-product and food industry urban pests from the taxa Acarina, Blattodea, Coleoptera, Diptera, Hymenoptera, Lepidoptera, Psocoptera, and Zygentoma. Various definitions and concepts historically and currently used for various pesticide application formulations and methods are also described. This review demonstrates that new technological advances have sparked renewed research interest in the optimization of conventional methods such as insecticide aerosols, sprays, fumigants, and inert gases. Insect growth regulators/disruptors (IGRs/IGDs) are increasingly employed in baits, aerosols, residual treatments, and as spray-residual protectants for long-term stored-grain protection. Insecticide-impregnated hypoxic multilayer bags have been proven to be one of the most promising low-cost and safe methods for hermetic grain storage in developing countries. Insecticide-impregnated netting and food baits were originally developed for the control of urban/medical pests and have been recognized as an innovative technology for the protection of stored commodities. New biodegradable acaricide gel coatings and nets have been suggested for the protection of ham meat. Tablets and satchels represent a new approach for the application of botanicals. Many emerging technologies can be found in the form of impregnated protective packaging (insect growth regulators/disruptors (IGRs/IGDs), natural repellents), pheromone-based attracticides, electrostatic dust or sprays, nanoparticles, edible artificial sweeteners, hydrogels, inert baits with synthetic attractants, biodegradable encapsulations of active ingredients, and cyanogenic protective grain coatings. Smart pest control technologies based on RNA-based gene silencing compounds incorporated into food baits stand at the forefront of current strategic research. Inert gases and dust (diatomaceous earth) are positive examples of alternatives to synthetic pesticide products, for which methods of application and their integration with other methods have been proposed and implemented in practice. Although many promising laboratory studies have been conducted on the biological activity of natural botanical insecticides, published studies demonstrating their effective industrial field usage in grain stores and food production facilities are scarce. This review shows that the current problems associated with the application of some natural botanical insecticides (e.g., sorption, stability, field efficacy, and smell) to some extent echo problems that were frequently encountered and addressed almost 100 years ago during the transition from ancient to modern classical chemical pest control methods.

“…Another possible explanation is the differences in dehydration among individuals may interpret this gained heterogeneity (Malia et al, 2016b). However, several pesticide studies on stored-product insects have been confirmed this heterogeneity response (Sehgal et al, 2013;Subramanyam et al, 2014;Tadesse et al, 2019).…”

Globally, there are growing concerns about the overuse of synthetic insecticides to their subsequent damage to the environment and mammalian. Therefore, developing new and safe eco-friendly insecticides based on natural products, such as essential oils,is considered a substitute for chemical pesticides in pest control. In the present study,mimicry the storage environment for grain products stored in a small scale by surface treatment method to determining the lethal and effective concentrations for three chemical insecticides (Imidacloprid, Zeta-cypermethrin and Lufenuron) and three essential oils (Citrus bergamia, Citrus limon and Cuminum cyminum) against larvae of Trogoderma granarium at various concentrations and time intervals. Results revealed that the C. bergamia EO exhibited high larvacidal activity compared to the other two oils, i.e.,30.36% after 24h of exposure at the higher concentration (10 v/v), while after 72h of exposure at the same,mortality reached 75.33%. Concerning chemical insecticides, the imidacloprid insecticides at all tested concentrations were the most effective against T. granarium larvae, leading to 40% mortality at the lower concentration (1v/v) after 24h. of exposure, and 96.66% mortality at the higher concentration(10 v/v)72h. post-exposure. Whereupon, C. limon oil had significantly higher LC50 and LC99 values than other oils, indicating that C. bergamia oil was more toxic against T. granarium larvae than to both oils. In contrast, LC99 values of Lufenuron were the highest significantly being about 1.61 and 2.31 times compared to Zeta-cypermethrin and Imidacloprid at the maximum concentration tested after 72h of exposure, respectively.In sum,our research focuses on the potential of selected EOs as a suitable substitute for chemical pesticides against this noxious species.

“…Interestingly, larvae of E. kuehniella show a preference for remaining on surfaces treated with spinosad, a response which might help improve its uptake and effi cacy (Athanassiou et al, 2018), and spinosad would appear to be compatible with the parasitoid Habrobracon hebetor, which can also be used for control of E. kuehniella (Mahdavi et al, 2015). Spinosad has a successful history of application against stored product pests (Subramanyam et al, 2014;Nayak & Daglish, 2017) and is often applied in combination with low doses of diatomaceous earth to improve its effi cacy (Machekano et al, 2017(Machekano et al, , 2019Gad et al, 2021) The combined use of this naturally-derived insecticide and an EPF could potentially increase the effi ciency of pest control while minimizing adverse chemical impacts (Paula et al, 2011;Sain et al, 2019). However, the possibility exists that certain insecticides could inhibit the germination or fungal growth of EPF, rendering them incompatible for joint application (da Silva et al, 2013).…”

We evaluated the effi cacy of four entomopathogenic fungi (EPF) and their compatibility with the bioinsecticide spinosad for control of Ephestia kuehniella (Zeller) under laboratory conditions. Three EPF, including Beauveria bassiana (Balsamo-Criveili) Vuillemin isolates Z1 and Iran 1395C, Lecanicillium (= Verticillium) lecanii (Zimmerman) Zare & Gams, isolate Iran 229, and Purpureocillium (Paecilomyces) lilacinum (Thom) Luangs-ard, Hywel-Jones & Samson, isolate Iran 1026 were tested against third and fi fth larval instars of Ephestia kuehniella using a fi lter paper bioassay. Mortality caused by the EPF ranged from 63.3-72.5% for third instars and 50-65.5% for fi fth instars, with LT 50 ranging from 8.4-10.5 d and 10.1-12.9 d, respectively. The effect of spinosad at LC 10 (= 26.2 ppm) on EPF spore germination was evaluated and found to be negligible, ranging from 0% for B. bassiana Z1 to 5.7% for P. lilacinum. The LC 50 values for spinosad against third and fi fth instar E. kuehniella larvae were 452.5 and 1446 ppm, respectively. Subsequently, spinosad at LC 10 was applied to third instar E. kuehniella larvae 24 h before application of the EPFs at LC 50 . The addition of spinosad to applications of L. lecanii and B. bassiana Z1 and Iran1395C isolates synergized their pathogenicity to E. kuehniella larvae, whereas the effect was merely additive for P. lilacinum. Our results suggest that these EPF isolates can be used effectively in combination with spinosad for management of E. kuehniella in stored products.
