“…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. However, the effectiveness of DE formulations against stored-product beetle species is temperature dependent (Fields and Korunic, 2000;Arthur, 2002;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.…”

“…Further experimental work is needed to confirm this inference. On the other hand, nothing is gained by increasing the SilicoSec ® rate from 1 to 1.5 g/kg of wheat (Athanassiou et al, 2003(Athanassiou et al, , 2005. However, exposure interval is more important than application rate because even at 1.5 g of SilicoSec ® /kg of wheat, short S. oryzae exposure (Յ48 h) results in increased survival.…”

“…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.

“…Nas últimas décadas, houve o aumento do interesse de pesquisadores de várias partes do mundo no uso da terra de diatomácea como inseticida para insetos de grãos armazenados, principalmente em cereais (KORUNIC, 1998;FIELDS & KORUNIC, 2000;MEWIS & ULRICHS, 2001;ATHANASSIOU et al, 2003). De acordo com SUBRAMANYAM & ROESLI (2000), a morte do inseto é atribuída à dessecação causada pelas propriedades de adsorção e à abrasividade da terra de diatomácea.…”

Resposta de Sitophilus oryzae (L.), Cryptolestes ferrugineus (Stephens) e Oryzaephilus surinamensis (L.) a diferentes concentrações de terra de diatomácea em trigo armazenado a granel

Formulações de terra de diatomácea de diferentes origens apresentam variação em toxicidade e em características físicas que afetam sua eficácia. Da mesma forma, diferentes espécies de insetos variam quanto a sua suscetibilidade ao produto. Adultos de Sitophilus oryzae (L.), Cryptolestes ferrugineus (Stephens) e Oryzaephilus surinamensis (L.) foram expostos a concentrações de 250, 500, 750, 1000 e 1250g t-1 de uma formulação de terra de diatomácea de origem brasileira (Keepdry®), em trigo armazenado, por diferentes períodos de exposição. Os grãos tratados com as diferentes concentrações foram colocados em frascos, com quatro repetições de 100g de grãos por tratamento, e infestados com os insetos. Os frascos foram mantidos em câmara climatizada a 25°C e 65% UR, avaliando-se a mortalidade periodicamente. O número de insetos mortos por parcela foi submetido à análise de variância e as diferenças entre as médias discriminadas pelo teste de Tukey a 5%. A mortalidade das três espécies foi diretamente relacionada à concentração e ao tempo de exposição, sendo que os melhores resultados foram obtidos com concentrações acima de 500g t-1. A espécie S. oryzae atingiu 100% de mortalidade somente no 14° dia de exposição, na concentração de 750g t-1. C. ferrugineus foi a espécie mais suscetível ao tratamento com a terra de diatomácea, com 100% de mortalidade a 500g t-1 já no 4° dia. Conclui-se que a terra de diatomácea utilizada apresenta um nível de controle satisfatório, e pode ser utilizada em programas de manejo de insetos, em trigo armazenado.
