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 accordance with FIFRA, essential oils of C. flexuosus and C. winterianus and their active ingredients, i.e., geraniol and citronella, along with a few other compounds, are eligible for exemption from pesticide registration from the U.S. Environmental Protection Agency. These biopesticides are classified as non-residual insecticides under Minimum-Risk Pesticide Products and can be used in all raw agricultural food commodities (Rust, 2010;Baker et al, 2018). With the removal of hazardous insecticides such as methyl bromide and endosulfan from the market, the developing of safer and less expensive crop protectants from locally available plant materials is likely to rise in developing countries.…”

“…Wats. and C. winterianus Jowitt (Poales: Poaceae) are plants in the grass family that are well-documented for their insecticidal activity against various agricultural pests (Amer and Mehlhorn, 2006;Wiltz et al, 2007;Pinheiro et al, 2013;Gusmão et al, 2013;Pinto et al, 2015;Zhang et al, 2016;Tak et al, 2017).Both C.flexuosus and C.winterianus oils have been considered non-residual insecticides and are exempted under Section 25(b) of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) (Rust, 2010). The present study aimed to evaluate the chemical composition of essential oils of C. flexuosus and C. winterianus and determine the insecticidal activity of the essential oils on colonizing CBB adult females.…”

Hypothenemus hampei is the most important insect pest of coffee in the world. H. hampei is controlled by using endosulfan and methyl bromide. However, using these two chemicals may pose pesticide resistance, bioaccumulation, and a threat to human health and the environment. This study evaluated the chemical compositions of essential oils from Cymbopogon flexuosus and C. winterianus and their insecticidal potential against H. hampei as an alternative to endosulfan and methyl bromide. The chemical profiles of the two essential oils showed that both constituted biochemically distinct monoterpenes and sesquiterpenes. The main compounds identified in C. flexuosus were citral, geraniol, and isoforms, representing 76.45% of the total composition, and other active ingredients were citronella, caryophyllene, citronellyl acetate, cadinene, linalool, and limonene. The composition of C. winterianus was citronella, nerol, and citronellol as principal components, corresponding to 66.47%, along with other active ingredients elemol, geranyl acetate, citronellyl acetate, germacrene, and limonene. Differential sensitivity of H. hampei adults was observed in the bioassay of two oils, where a dose-dependent increase in mortality was observed. Among two concentrations of both essential oils, 100% mortality was observed at 500 and 1000 ppm within 48 and 24 hours of treatment, respectively. The significant biological activity of both Cymbopogon species oils indicated a potential source for further development of botanical pesticides as an effective, useful alternative for currently used toxic insecticides. Additionally, essential oils of C. flexuosus and C. winterianus and their active ingredients are classified as non-residual insecticides and are eligible for a pesticide registration exemption.
