“…Therefore, the studies on eco-friendly natural products have increased in order to reduce the negative effects of insect resistance. The chloroform, methanol:chloroform (1:1) and methanol extracts obtained from mosses were found to be suitable for the protection of stored products [20]. Therefore, some bryophytes contain compounds that are easily extracted and would serve as effective insecticides.…”

The composition of fatty acids and insecticidal effects was performed for the Turkish mosses Dicranum scoparium, Hypnum cupressiforme, Polytrichastrum formosum, Homalothecium lutescens and the Turkish liverwort Conocephalum conicum. All structures were determined by means of gas chromatography and gas chromatography-mass spectrometry techniques. The determination of fatty acids was done using a simple and mild method that utilized different solvent extractions ranging from nonpolar to polar solvents (hexane, dichloromethane, chloroform, ethyl acetate and methanol, respectively), and the samples were powdered with and without liquid nitrogen. The correlations between the saturated and unsaturated fatty acid contents depending on the solvent polarity and their crushing process by liquid nitrogen were observed. The insecticidal activity of the bryophytes was analyzed by using the methanol, hexane and esterified methanol extracts. The hexane extracts of Polytrichastrum formosum showed the highest insecticidal activity (70.33%) against Sitophilus granarius. Contact toxicity activities of lauric, myristic and palmitic acids besides single dose studies of the solvent extracts were carried out. The highest mortality rate (53.34%) was obtained from the myristic acid among the tested pure fatty acids. The activities of palmitic and lauric acids were 17.75% and 4.32%, respectively.

“…The highest activity against stored product insects has been reported for methanol extracts, ethyl acetate extracts, and hexane extracts (Abay et al 2012).We have found in the behavioural responses of mated granary weevils to blends of cereal volatiles that mated females of S. granarius were attracted to blend 1, 4, and 5 at concentrations of 100, 100, 1, and 10 ng/min, respectively. In contrast, mated males were attracted only to blend 5 at a concentration of 10 ng/minute.…”

“…Pests develop large populations, consume food commodities, and contaminate the goods with shed skins, faeces, hairs, webbing, cadavers, and toxins (Belda & Riudavets 2010;Grethe et al 2011;Niedermayer & Steidle 2013). The degree of damage is directly related to the infestation rate which, in turn, is determined by factors such as the number of laid eggs, and the survival and fecundity of offspring (Nawrot et al 2010;Abay et al 2012). In developed countries, these insects can cause losses of up to 9%, but in developing countries the losses can be more than 50% (Germinara et al 2010;Piasecka-Kwiatkowska et al 2014).…”

Wenda-Piesik A., Piesik D., Krasińska A. (2018): Response of mated insects of both sexes of granary weevil to blends of volatiles -short communication. Plant Protect. Sci., We report the behavioural responses of mated granary weevils to blends of cereal volatiles. Four doses were applied on filter paper (1, 10, 100, and 1000 ng/min in 50 µl of hexane applied on filter paper). A Y-tube experiment revealed that mated females of Sitophilus granarius were attracted to blend 1, 4, and 5 at concentrations of 1000, 100, 1, and 10 ng/min, respectively. Mated males were attracted only to blend 5 at a concentration of 10 ng/minute. Yet, the mated weevil females and males were repelled by the highest concentration (1000 ng/min) for all tested blends. Moreover, both mated sexes were repelled by 100 ng/min in blends 2, 3, 5, and 6. Additionally, females were repelled by 10 ng/min in blend 6. We claim that the blend of volatiles and their concentration can induce the insect behaviour.

“…The acetone was also applied at the same volume as the blank in the control. The stock solutions of the essential oils were applied topically to the dorsal surface of the thorax of the insects 41,42 . After the sample application the insects were transferred to the 65 mL tubes which were filled with 10 g of wheat.…”
