“…Currently, there is great worldwide research interest in the use of innovative traditional methods of protection against storage pests, especially the use of botanical substances. The most studied substances are plant oil extracts [ 568 , 569 ]. However, in rural areas, botanical ash ( Figure 5 L,N) [ 29 , 555 , 570 ] or whole parts of dried or fresh plants ( Figure 5 O) have also been mixed with grain as protectants or repellents [ 528 , 571 ].…”

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.

“…In the recent years, control of stored product pests is commonly done by chemical gas pesticides, whose uncontrolled use of these compounds causes problems such as residues of toxins in food and the emergence of resistant populations (Negahban et al, 2007;Rajendran & Sriranjini, 2008). The existence of such problems has led researchers to seek alternative and less hazardous methods such as diatomaceous earth and powders of plants to efficient and safe control of stored product pest (Bohinc et al, 2013(Bohinc et al, , 2018. The secondary metabolites of plants can partly be the alternatives of synthetic pesticides because of some features such as rapid decomposition, reduction of environmental pollution, wider range of effects and suitability for small scale applications, especially storage facilities, (Rajendran & Sriranjini, 2008;Yang et al, 2014).…”

Effects of Teucrium polium L. (Lamiaceae) essential oil and α-pinene on the detoxifying-and intermediary engaged enzymes of Ephestia kuehniella Zeller, 1879 (Lep.: Pyralidae)Abstract: This study investigated the effect of Teucrium polium L. essential oil (Tp EO) and α-pinene as its major component on the detoxifying-and intermediary-engaged enzymes of Ephestia kuehniella Zeller. Fourth instar larvae were separately fed on the treated artificial diets incorporated with LC 50 concentration of Tp EO (4.91 μl ml −1 ) and α-pinene (10.66 μl ml −1 ). After three time intervals (24, 48, 72 hours), larval hemolymph was extracted to determine enzymatic activities. Activity of esterase, alanine and aspartate aminotransferases, aldolase, lactate dehydrogenase, and alkaline phosphatase were decreased in the treatments compared with the control. No significant differences were observed between some enzymes in the treated larvae highlighting their ineffectively role to detoxify and to metabolize Tp EO and α-pinene in the hemolyph of E. kuehniella larvae.

Ličinke četrtega štadija so bile hranjene z umetnimi pripravki, ki so vsebovali LC 50 koncentracijo Tp EO (4,91 μl ml −1 ) in α-pinena (10,66 μl ml −1 ). Po treh časovnih presledkih (24, 48, 72 ur) je bila za določanje encimske aktivnosti ekstrahirana hemolimfa ličink. Aktivnosti esteraze, alanin in aspartat aminotransferaz, aldolaze, laktat dehidrogenaze in alkalne fofataze so se zmanjšale po obravnavanjih v primerjavi s kontrolo. Pri tretiranih larvah ni bilo značilnih razlik med posameznimi encimi, kar kaže na neučinkovitost fiziologije močne vešče pri tretiranju s Tp EO ali z α-pinenom.Ključne besede: Teucrium polium L.; močna vešča; eterična olja; detoksifikacijski encimi; fenoloksidaza; toksičnost; fiziološki odziv Acta agriculturae Slovenica, 113/2 -2019 252 M.

“…In a previous experiment describing effects of Oulema melanopus (L.), the cereal leaf beetle, on field wheat, the wheat was planted on site at the University of Ljubljana, Slovenia, in Autumn and harvested on 19 and 25 July [22]. In a different experiment in which wheat was grown in Serbia, which is in the Balkan peninsula near Slovenia, the harvest date was also late July [23]. Thus, the start date of August 1 for the simulations was chosen to correspond to an average binning date for wheat harvested in Slovenia, regardless of location.…”

The use of aeration, which refers to cooling of a grain mass using low-volume airflow rates with ambient air, is an under-utilized component of management programs. A model simulation study was conducted for the country of Slovenia by examining historical weather data for 10 selected sites to determine if sufficient cooling hours <15 °C were available in August and September to cool stored wheat. The weather data were then coupled with a degree-day model to determine if a generation of Sitophilus oryzae (L.), the rice weevil, could be produced in the absence of aeration, using a start date of 1 August. The weather data for September was used to classify Slovenia into different risk zones, depending on the number hours <15 °C. Three sites from each zone, from warmest to coolest, Portorož, Novo Mesto, and Lesce, were further examined using a web-based aeration model and insect population growth model for S. oryzae developed by Texas A&M University Beaumont TX for cooling stored rough rice, to predict bin temperatures and population growth from 1 August to 30 November. The results show that, for most of Slovenia, in the absence of aeration, a complete generation of S. oryzae could occur based on an infestation beginning 1 August. The use of aeration immediately cooled stored wheat in the three selected sites, resulting in a dramatic decrease in predicted populations of S. oryzae in aerated wheat compared to unaerated wheat. The results show that the use of aeration may be expanded in Slovenia for management of stored commodities, and it could help alleviate dependence on insecticides for insect pest management after harvest.
