“…Used Si NPs as a concentrations of (0. These results are agree with [31] who tested silica products against the field pests Epilachnavigin tioctopunctata (F.) and spodoptera litura (F.), the results showed that 100% mortality rate was achieved two days after treatment of adult E. vigintioctopunctata and S. litura larvae, [25] who found that applying Mg silicate at concentrations of 1.0 up to 6.0 g/L resulted in 28.0-38.0% cotton leaf worm larval mortality with higher values in early larval instars as compared with late instars and [32] showed that one of the benefits of silica Nps is its ability to stop pest feeding almost immediately after feeding on treated parts of the soybean plant. Its unique mode of action ends the damage quickly, so crops are protected.…”

Field and laboratory experiments were conducted at Taifaa region and Agricultural research station, Kafr El-Sheikh Governorate, during two successive seasons 2019/2020 and 2020/2021. To estimate the efficiency of alternative materials for controlling Spodoptera littoralis, some silica sources were incorporated to the soil such as (straw and husk) and sprayed on the plants, spray such as potassium, magnesium, sodium silicate and Si NPs. Burnt husk added to the soil at the rate of 200 g/m 2 gave the highest reduction 50.

An experiment was conducted during 2021-22 to study the effect of Diatomaceous earth and biopesticides against gram pod borer [Helicoverpa armigera (Hubner)] in chickpea at Central Research Farm (CRF), Department of Entomology, SHUATS, Prayagraj during rabi season with seven treatments i.e., Diatomaceous earth (T1), Neem oil 3% (T2), Beauveria bassiana 1x108 CFU/ml (T3), Metarhizium anisopliae1x108 CFU/ml (T4), Diatomaceous earth+neem oil 3% (T5), Diatomaceous earth+ B.bassiana 1x108 CFU/ml (T6), Diatomaceous earth+ M. anisopliae1x108 CFU/ml (T7) and untreated control (T8) was evaluated against chickpea pod borer (H.armigera). Results revealed that, Among the different treatments, the highest per cent population reduction of chickpea pod borer was recorded in Diatomaceous earth+neem oil 3% (74%) followed by Diatomaceous earth+ B.bassiana1x108CFU/ml (73%), Diatomaceous earth+ M.anisopliae 1x108CFU/ml (72%). It is followed by Diatomaceous earth (68%) and neem oil 3% (42%), B.bassiana 1x108CFU/ml (40%) and M. anisopliae 1x108CFU/ml (36%) was the least effective among all treatments. While, the highest yield 23.2q/ha was obtained from the treatment Diatomaceous earth+neem oil 3% as well as B:C ratio 1:4.1. It was followed by Diatomaceous earth+ B.bassiana1x108CFU/ml (1:3.8), Diatomaceous earth+ M.anisopliae1x108CFU/ml (1:3.7), Diatomaceous earth (1:3.5), neem oil 3% (1:2.4), B.bassiana1x108CFU/ml (1:2.3), M. anisopliae 1x108CFU/ml (1:2.1), as compared to Control (1:0.9).

“…For insect pest management, it is used principally in the control of grain beetles (Golob 1997;Korunic 1998;Mewis and Ulrichs 2001;Stadler et al 2012, among others). However, its application has been shown to be of use in the control of cockroaches and silverfish (Faulde et al 2006); Mole crickets (Thompson and Brandenburg 2006); the potato ladybird, Epilachna vigintioctopunctata; and a lepidopteran pest caterpillar, Spodoptera litura (Mucha-Pelzer et al 2008). DE has also been used in the control of internal parasitic infections in poultry (Bennett et al 2011).…”

International audienceSmall hive beetles (SHBs) are a global pest of European honeybee colonies. In the laboratory, the survival of adult SHBs was evaluated in relation to relative humidity (RH = 56, 64, 73, 82 and 96 %) and treatment with diatomaceous earth (DE) across 4 days. Low RH reduced survival. The application of DE reduced survival in addition to RH. Adults treated with corn flour (control) showed no difference in survival from untreated beetles. Scanning electron microscopy images showed no scarification of adult beetle cuticle after exposure to DE; therefore, water loss is likely facilitated through non-abrasive means such as the adsorption of cuticular lipids. The data agree with the hypothesis that DE causes mortality through water loss from treated insects. Egress, ingress, mortality and the egg-laying behaviours of beetles were observed in relation to a popular in-hive trench trap with and without the addition of DE. Traps filled with DE resulted in 100 % mortality of beetles compared with 8.6 % mortality when no DE was present. A simple method for visually determining beetle sex was used and documented
