“…Some earlier studies support the obtained data, pirimipho-methyl is the most organophosphate, and deltamethrin the most common pyrethroid and both are used as chemical protectants of stored grain throughout the world (White andLeesch, 1996, Arthur andSubramanyam, 2012). Similar results were obtained by (Daglish et al, 1993) who reported that organophosphorus (fenitrothion, chlorpyrifos-methyl and pirimiphos-methyl) lost their activity during storage compared to synthetic pyrethroid compounds (permethrin and deltamethrin). Some authors have found organophosphate more efficient than pyrethroids (Arthur, 1992), while others conversely reported pyrethroids were efficient than organophosphates (Afridi et al, 2001;Klajic and Perci, 2009).…”

“…Pirimiphos-methyl is widely used in the major grain producing countries to protect against insect attacks, and this organophosphate insecticide has long persistence (Fleuret-lessard et al, 2007;Yu et al, 2014). The organophosphate chlorpyrifos-methyl is also commonly used as grain protectant since the 1960s (Samson et al, 1989;Daglish, 1993;Arthur, 1996).…”

A greenhouse experiment was carried out during 2017 and 2018 summer seasons at Desert Research Center farm, Ras Sudr, South Sinai. The aim of the experiments was to investigate the effect of different rootstocks and citric acid foliar spray on growth, yield and its components and net income as well as net income diffraction percentage and mineral composition of cucumber plant Safi (F1) hybrid. The foliar spray of citric acid was four concentrations (0, 200, 300 and 400 ppm) and the grafting treatments were check nongrafted, Safi (F1) grafted onto Shentoza or on Coplt rootstocks (Cucurbita moschata Duch.). Strip plot design was used where main plots were assigned for foliar spray and sub plots for grafting. Results showed that grafting increased plant growth, yield and its components, marketable yield, net income and net income diffraction percentage. The increasing was differing according to rootstock source. Grafting, also, increased leaf chlorophyll and fruit potassium and calcium content while sodium content was decreased. The highest values of all measured parameters were obtained, in general, with cucumber plants grafted onto Shentoza rootstock. As for citric acid effects, results indicated that its application increased all parameters except sodium content; the highest values were obtained with cucumber plants sprayed with citric acid at rate 400 ppm. As for the combination between grafting technic and citric acid concentration, the best growth and highest yield and its components were obtained with the cucumber plants grafted onto Shentoza rootstock combined with the highest concentration of citric acid. Also, leaf chlorophyll and potassium of fruits recorded the highest increases, whereas fruit calcium and sodium were not significantly affected

“…Our study demonstrated concentration-dependence of thyme EO effects on A. obtectus mortality, survival time and shape of survival curves. Insecticidal efficacy of thyme EO was similar to the effects of some commercial botanical insecticides [94], but lower compared to conventional insecticides [95]. The main compounds of the thyme oil are oxygenated monoterpens thymol, carvacrol, and linalool, and non-oxygenated monoterpene p-cymene [71].…”

The bean weevil Acanthoscelides obtectus Say (Coleoptera: Chrysomelidae: Bruchinae) can cause significant losses in production of its primary host common bean Phaseolus vulgaris L. To avoid bean protection with environmentally risky chemical insecticides and provide sustainable and safe production of food, new pest management methods based on natural compounds are investigated. In the present study, we evaluated protective potential of the essential oil (EO) from the common thyme Thymus vulgaris L. applied on bean seeds. We assessed residual contact toxicity of thyme EO and its effects on A. obtectus longevity, oviposition and adult emergence. Furthermore, to elucidate the role of oxidative stress in thyme EO toxicity, we estimated the levels of oxidatively damaged proteins and lipids, as well as the level of thiols which have important role for antioxidant capacity. We found that thyme oil significantly reduced adult survival and longevity, induced oxidative damage to lipids and proteins and depleted protein and non-protein thiols in a concentration-dependent manner. Females appeared to be more tolerant to thyme oil treatment than males. Sublethal EO concentrations affected oxidative stress indices, deterred oviposition and strongly inhibited adult emergence. The results suggest that thyme oil has the potential to be used as an ecofriendly insecticide for A. obtectus control.

“…The bean weevil A. obtectus was the only insect pest of stored beans reported by farmers. This cosmopolitan insect pest has also been reported as the most important pest of stored beans in Asia (Thakur, 2012), America (Quentin et al, 1991;Silva andCosta, 2016 andBaldin et al, 2017), Africa (Rugumamu, 2014), Europa (Rugumamu, 2014) and Oceania (Daglish et al, 1993). In fact, larvae of A. obtectus enter the common bean seeds from the first instar stage and consume the reserves contained in the cotyledons which causes great losses (up to 30%) (Baldin et al, 2017).…”

Common bean (Phaseolus vulgaris L.) is a legume that contributes to food security and poverty reduction in Benin. However, there is very little information on its production constraints, varietal diversity, storage practices, storage insect management, and seed system. While these information are necessary for use in breeding programs and a better conservation of this legume. To fill these gaps, ethnobotanical surveys were conducted in 23 villages selected through central Benin using participatory rural appraisal tools and techniques. The number of beans landraces ranged from 3 to 5 per village (4.7 on averages) and from 1 to 4 per household (1.7 on average). A total of 26 common beans folk varieties, corresponding to 12 climbing bean landraces were recorded in the study area. A high rate of threat of landraces disappearance was recorded through surveyed villages. Various seeds storage tools were recorded and the seed system was essentially informal. The use of inert substances, chemical insecticides and insect repellent/insecticidal plants to control storage insects has been reported in the study area. Farmers noted a differential susceptibility of common bean landraces to storage insect pest. Our findings showed that there is an urgent need of development of integrated bean storage insect management strategies.
