“…The study findings indicate that warehousing facilities in the Northern province face numerous challenges, including post-harvest damages, insufficient storage capacity, ineffective Third-Party Logistics strategies, and substandard transportation within the supply chain, resulting in lower profits for farmers. These results corroborate previous studies by Adhikarinayake (2015), Sundaram (2014), Donahaye et al (2016), Ashenbaum et al (2015), Wasala et al (2014), andJacob et al (2014). Both current and past research emphasize that high-standard warehousing boosts farmers' ability to sell products at optimal market prices.…”

“…There's typically a time lag between production and consumption; during this period, commodities are stored by the producer, middleman, or consumer (Bowersox, 2018). In Sri Lanka, commodities are often stored by producers who lack sufficient storage systems (Wasala et al, 2014). TPL providers can offer warehousing services, carrying excess produce forward to future consumers (Kulkarni, 2012).…”

“…Warehousing significantly affects the flow of goods from producers to consumers. It strengthens the supply chain, preventing food waste and shortages due to inadequate transport and storage (Wasala et al, 2014). Appropriate storage facilities prevent loss and increase supply chain efficiency (Jacob et al, 2014).…”

“…Synthetic chemicals are used for the management of different insect pests. These pesticides are still used in developing countries for the control of stored grain insect pests (Koureas et al, 2012;Wasala et al, 2016). Extensive use of synthetic insecticides such as of methyl bromide and phosphine has resulted in development of resistance in stored grain insect pests (Benhalima et al, 2004;Pimental et al, 2007).…”

W heat (Triticum aestivum L.) is a major cereal crop and an important constituent of human diet all over the world. In Pakistan, it is the main staple grain crop being cultivated by 80% farmers. It contributes about 1.7 and 8.7% to GDP and valueadded in agriculture, respectively. The area under Abstract | Khapra beetle, Trogoderma granarium Everts (Coleoptera: Dermestidae), is an economically important stored grain and quarantine pest. It has developed considerable resistance to phosphine and other frequently used grain protectants. This situation necessitates looking for alternate biorational control options such as botanical and microbial insecticides. This in-vitro study assessed the anti-insect potential of four local plant extracts and two promising microbial formulations against 5 th instar larvae of T. granarium. Toxicity bioassays revealed that the extracts of Citrus reticulata L. and Solanum nigrum L. were most effective against T. granarium causing significantly higher larval mortality (35 -40%) than other botanical treatments. Similarly, the highest concentration (15%) of C. reticulata extract exhibited maximum repellency (88%) of larvae, followed by Datura stramonium (84%) and Azadirachta indica (79%) at 24 h post-exposure. Regarding bioassays with microbial insecticides, maximum mean mortality of larvae (i.e. 42.6 and 46.1%) were exhibited by the highest concentration of Bacillus thuringiensis (18000 CFUs mg -1 ) and Lecanicillium lecanii (1.0 × 10 9 conidia g -1 ) recorded at 5 th and 9 th day of bioassay, respectively. Based on overall results, the local botanical extracts, particularly peel extract of C. reticulata and leaf extract of S. nigrum and microbial formulations of B. thuringiensis and L. lecanii are recommended to the indigenous farmers as biorational options for the management of T. granarium and other stored grain insect pests.

Influence of ozone gas on the khapra beetle, Trogoderma granarium (Coleoptera: Dermestidae) in stored wheat

Khapra beetle, Trogoderma granarium Everts, 1898 (Coleoptera: Dermestidae) is one of the most notorious pests of stored grains. This study was aimed to evaluate the efficacy of ozone against 2nd and 5th instars and adults of T. granarium in stored wheat kernels under laboratory conditions. Four ozone concentrations of 300, 600, 900, and 1200 parts per million by volume (ppmv) were used. The results revealed that the LC50 values were 249.76 ppmv for adult, 446.75 ppmv for 5th instar, and 275.30 ppmv for 2nd instar of T. granarium after 2 h exposure to ozone. No adults emerged when the ozone concentration was 1200 ppmv, while emergence was high in controls (91.20%) after a 1-h exposure period. The highest ozone concentration of 1200 ppmv resulted in strong grain protection against adult and 2nd and 5th instars, with a 0.63%, 0.73%, and 1.16% loss in grain weight, respectively. Chemical analysis of treated wheat kernels at a concentration of 1200 ppmv ozone showed no significant differences (p > 0.05) in fat, moisture, ash, carbohydrate, fiber, and protein content of ozone-treated wheat kernels compared to untreated grain. Thus, ozone can be effectively used to control T. granarium and provides sufficient protection for stored wheat.
