“…The level of damage for each country varies depending on the region, type of rice, climate, and duration of storage [3]. For instance, rice damage in Ukraine can reach 25-50%, Australia 0.7%, Pakistan 16%, India 20-25% in 2010-2011, and Poland 3-5% [6][7][8]. According to Phillips and Throne [9], the loss of storage products due to S.oryzae pests ranges between 9% in developed countries and 20% in developing countries.…”

The aim of this study was to determine the effect of Pandanus (Pandanus amaryllifolius 20 Roxb.) and Neem (Azadirachta indica) leaves powder on the repellency, mortality, and weight loss 21 of grains due to Sitophilus oryzae. The methodes of this study used a completely randomized design 22 (CRD) with 7 treatments and 4 replications. The results of this study indicate that the best treat- 23 ment in terms of causing repellency was the treatment of 10 grams of pandanus with a percentage 24 of 87.5%, while the best treatment in terms of causing pest mortality and was also able to reduce 25 the risk of rice weight loss due to Sitophilus oryzae was treatment 10 gram of neem with a mortality 26 percentage of 76.25% and weight loss of rice 3.14%. This research showed that neem leaf com- 27 pounds are better in terms of causing mortality, while Pandanus compounds are better in terms of 28 causing mortality of Sitophilus oryzae.

The present study was designed to determine chemical composition of essential oils extracted from different species of the Myrtaceae family and to evaluate their insecticidal activities against Tribolium castaneum (Coleoptera: Tenebrionidae). The essential oils of 10 species were extracted by hydrodistillation and analyzed by a gas chromatography-flame ionization detector (GC-FID) and gas chromatography-mass spectrometry (GC-MS). The main component of Eucalyptus crebra, E. microtheca, E. rudis and Melaleuca quinquenervia essential oils was 1,8-cineole (31.6-49.7%). E. melanophloia and E. tereticornis contained p-cymene (41.8-58.1%) as a major component, while Eucalyptus kitsoniana and E. pruinosa essential oils were dominated by α-pinene (25.8-31.4%). Eugenol methyl ether was identified as a major component in M. bracteata essential oil (82.3%). α-Pinene (31.4%) was the main component in the C. viminalis essential oil. Essential oils of all selected plant species showed good insecticidal activities against T. castaneum when compared with pyrethroid as a positive control. Eucalyptus rudis proved most potent against T. castaneum, followed by M. bracteata, M. quinquenervia, and C. viminalis. The results of this study indicate that essential oil of Myrtaceae leaves have potential to be used in the control of T. castaneum.

The aim of the study was to check the effect of Carum carvi L. essential oil and L-carvone on the emigration, repellence and mortality of Sitophilus oryzae L. In the experiments with caraway essential oil, concentrations of 0.1%, 0.5% and 1% were used, and concentrations of 0.05, 0.1, 0.5 and 1% were used with L-carvone. We assessed whether, in what concentrations and after what exposure time the substances acted on S. oryzae as repellents and/or insecticides. The laboratory tests were carried out at 29 ± 1 °C with 60 ± 5% relative humidity (RH). The deterrence, mortality and abundance of insects were noted after 1, 2, 3, 4, 5, 24 and 48 h. For caraway essential oil and L-carvone, the highest repellency was not shown in the highest concentrations that were used in the tests but in the lower concentrations of 0.5% and 0.1%, respectively. In all used concentrations, caraway essential oil showed repellent effects on S. oryzae. The highest repellency (60–98%) was caused by 0.5% caraway essential oil after 1, 2, 3, 4 and 5 h of research and by 0.1% L-carvone (16–100%). The highest mortality of S. oryzae was caused by 0.5% caraway essential oil and 1% L-carvone. L-carvone at a concentration of 0.05% did not cause mortality in S. oryzae. In conclusion, the greatest repellent effects on S. oryzae were caused by lower doses of caraway essential oil and L-carvone. These compounds do not show the normal relationship described in the previous literature on warehouse pests, in which the repellency increased with increasing concentrations of the tested plant material.
