“…DE dusts are typically composed of 80-93% silicon dioxide, as well as varying amounts of organic matter, clay minerals, magnesium carbonate, among others (Antonides, 1998;Subramanyam and Roesli, 2000;Shah and Khan, 2014). DE works by abrading the insect's cuticle, interfering with the water retention ability of the insect, and results in death through desiccation (Korunić, 1998;Dowdy and Fields, 2002).…”

Unsanitary storage bins can harbor grain-infesting insects, including the red flour beetle, Tribolium castaneum (Herbst). In a previous study involving heat treatment of empty bins, temperatures in the range of 50-55C for 2-4 h were effective in completely killing storedproduct insects. Previous research in flour mills showed improved efficacy in killing storedproduct insects by using diatomaceous earth (DE) dusts at temperatures below 50°C. In the current study, the efficacy of a diatomaceous earth formulation (DiaFil® 610) applied to concrete arenas, to simulate floor of empty bins, was examined at three application rates (0, 2.5 and 5.0 g/m 2) to control T. castaneum adults at five constant temperatures (28, 36, 42, 44, and 46°C). Ten adults of T. castaneum were placed on individual untreated and DE-treated concrete arenas for 4, 8, 12, and 24 h at each of the five temperatures. The efficacy of DE against T. castaneum adults increased with an increase in temperature and exposure time. Generally more adults died at 5.0 g/m 2 when compared with 2.5 g/m 2. In 2.5 and 5.0 g/m 2 DE treatments, exposure for 12 h at a temperature of 42°C resulted in 73-77% mortality of adults with 100% mortality observed after 24 h. At 44 and 46C, 100% mortality of adults was observed after 24 h of exposure at both DE rates. At these two temperatures, the high mortality in untreated arenas (controls) at 8, 12, and 24 h exposures ranged from 27-100% confounding the true effects of DE. Our results suggest that combined use of DE and temperatures below 50C can be used as an integrated approach for controlling insects in empty bins prior to storage of newly-harvested grain.

“…By milling, a fine, talc‐like powder or dust is obtained; it is extremely stable and not reactive and is considered non‐toxic to mammals. It acts as an insecticide by absorption of epicuticular lipids and fatty acids, leading to desiccation in arthropods . Recent research has focused on enhanced DEs with other insecticides to allow control at low doses.…”

“…It acts as an insecticide by absorption of epicuticular lipids and fatty acids, leading to desiccation in arthropods. 21 Recent research has focused on enhanced DEs with other insecticides to allow control at low doses. For example, a mixture of DE with the plant (Celastrus angulatus) extract bitterbarkomycin (sesquiterpenes) was evaluated against the grain pest, Rhyzopertha dominica, and was found to be effective at dose rates as low as 150 mg kg −1 of wheat.…”

Natural compounds and living organisms continue to play a limited role in crop protection, and few of them have reached the market, despite their attractiveness and the efforts made in research. Very often these products have negative characteristics compared to synthetic compounds, e.g., higher costs of production, lower effectiveness, lack of persistence, and inability to reach and penetrate the target plant. Conversely, nanotechnologies are having an enormous impact on all human activities, including agriculture, even if the production of some nanomaterials is not environmentally friendly or could have adverse effects on agriculture and the environment. Thus, certain nanomaterials could facilitate the development of formulated natural pesticides, making them more effective and more environmentally friendly. Nanoformulations can improve efficacy, reduce effective doses, and increase shelf‐life and persistence. Such controlled‐release products can improve delivery to the target pest. This review considers certain available nanomaterials and nanotechnologies for use in agriculture, discussing their properties and the feasibility of their use in sustainable crop protection, in particular, in improving the effectiveness of natural bio‐based agrochemicals. © 2019 Society of Chemical Industry

“…No entanto, a ocorrência crescente de populações resistentes (BOYER et al, 2012) e os riscos ambientais associados a essa prática (PHILLIPS & THRONE, 2010) têm catalisado iniciativas no sentido de se buscarem adequações tecnológicas e alternativas para a racionalização do uso desses xenobióticos (ALVES FILHO, 2002). Diante desse contexto, o uso de pós inertes, técnica utilizada pelos agricultores de subsistência antes do advento dos inseticidas sintéticos, tem ressurgido como uma importante e promissora alternativa (SHAH & KHAN, 2014). A terra de diatomácea (sedimento de carapaças de algas diatomáceas) é o pó inerte mais estudado, sendo utilizado para o controle de insetos de grãos armazenados em vários países do mundo como Austrália, Canadá e Estados Unidos (ATUI et al, 2003).…”
