“…Our results are in accordance with previous laboratory tests indicating that SilicoSec ® is effective against adults of S. oryzae (Athanassiou et al, 2003(Athanassiou et al, , 2005.

“…98 and 100%, respectively. Similar results were also reported by Athanassiou et al (2003Athanassiou et al ( , 2004Athanassiou et al ( , 2005. However, the authors noted that, despite the high level of parental mortality, progeny production in the treated substrate could not be avoided at this dose rate, and concluded that 1 g/kg of wheat was the suitable dose rate to suppress progeny completely.…”

“…According to the results of the present study, the effectiveness of SilicoSec ® against S. oryzae adults increases with temperature. The difference between 27 and 30°C was negligible when insects were exposed to a DE-treated substrate for intervals Ն7 d. In a recent study with the same DE formulation, Athanassiou et al (2005) also noted an increase in the mortality of S. oryzae adults in SilicoSec ® treated wheat, as temperature increased from 22 to 32°C. Similarly, Arthur (2002) reported increased S. oryzae adult mortality with the increase of temperature after 1 wk of exposure when the DE formulation "Protect-It" was used.…”

“…DE formulations are usually applied directly to the product with almost the same technology as traditional residual insecticides (Subramanyam and Roesli, 2000), so there is practically no need for expensive changes in application machinery in stored-grain facilities. Several studies have shown that DE formulations are effective against a wide range of species, but researchers underline the fact that DE efficacy can be affected by several biotic or abiotic factors; e.g., temperature (Aldryhim, 1990(Aldryhim, , 1993Arthur, 2000Arthur, , 2002Fields and Korunic, 2000;Athanassiou et al, 2005), moisture content or relative humidity (Arthur, 2000(Arthur, , 2002Fields and Korunic, 2000;Vayias and Athanassiou, 2004), and type of product (Athanassiou et al, 2003). Recent laboratory experiments revealed the significant effect of insect strain (Rigaux et al, 2001) and stage (Mewis and Ulrichs, 2001;Vayias and Athanassiou, 2004).…”

The insecticidal efficacy of the diatomaceous earth formulation SilicoSec ® (Biofa GmbH) against adults of the rice weevil, Sitophilus oryzae, was evaluated in laboratory experiments on stored wheat. Bioassays were conducted at three temperature levels, 22, 27 and 30°C, two relative humidity (rh) levels, 55 and 65%, and four dose rates, 0.25, 0.5, 1 and 1.5 g of SilicoSec ® /kg of wheat. Three different aged-adult groups, 1, 2 and 7 d-old, were exposed. The mortality of exposed adults increased with the exposure interval and dose rate. Also, the increase of temperature increased S. oryzae mortality in all exposure intervals examined. The increase of rh from 55 to 65% caused a significant decrease in S. oryzae mortality. The age of the exposed individuals did not have a direct effect on SilicoSec ® efficacy.

Applications of natural zeolites on agriculture and food production

2017

View full text Add to dashboard Cite

Zeolites are crystalline hydrated aluminosilicates with remarkable physical and chemical properties, which include losing and receiving water in a reverse way, adsorbing molecules that act as molecular sieves, and replacing their constituent cations without structural change. The commercial production of natural zeolites has accelerated during the last 50 years. The Structure Commission of the International Zeolite Association recorded more than 200 zeolites, which currently include more than 40 naturally occurring zeolites. Recent findings have supported their role in stored-pest management as inert dust applications, pesticide and fertilizer carriers, soil amendments, animal feed additives, mycotoxin binders and food packaging materials. There are many advantages of inert dust application, including low cost, non-neurotoxic action, low mammalian toxicity and safety for human consumption. The latest consumer trends and government protocols have shifted toward organic origin materials to replace synthetic chemical products. In the present review, we summarize most of the main uses of zeolites in food and agruculture, along with the with specific paradigms that illustrate their important role. © 2017 Society of Chemical Industry.

Laboratory bioassays were carried out in order to evaluate the effectiveness of two diatomaceous earth (DE) formulations, Insecto and SilicoSec, against adults of Rhyzopertha dominica (F) in eight different grain commodities. The adherence of the two DEs to each grain was also measured. The eight grains tested were wheat, whole barley, peeled barley, oats, rye, triticale, rice and maize. These commodities were treated with the DEs at three rates, 0.75, 1.0 and 1.5 g DE kg(-1) grain. The mortality of R dominica adults was measured after 24 h, 48 h, 7 days and 14 days of exposure in the treated grains at 26 degrees C and 55% RH. After the 14-day mortality count, all adults were removed and the treated grains retained under the same conditions for a further 60 days. The treated grains were subsequently examined for F1 progeny. Significant differences were recorded among the eight grain types as well as between the DE formulations tested. After 14 days of exposure, even at the lowest DE rate for both formulations, adult mortality was high (>90%) in wheat and triticale. In contrast, adult mortality was significantly lower in peeled barley. Increasing the rate improved the efficacy of the DEs significantly in only some of the grains tested. Reproductive capacity in all the treated grains was significantly suppressed when compared with untreated grains. Generally, more F1 individuals of R dominica were noted in the treated peeled barley than in the other commodities. Significant differences in the percentage of DE retention were noted among the eight grains. The highest retention level was noted in rice (>87%) and the lowest in maize (<6%). However, the degree of DE adherence to a given grain was not always indicative of the effectiveness of DE against R dominica.
