“…Inhibition of AChE was reported for crude extracts from various plant families, including those that show insecticidal activity, for example, Asteraceae or Solanaceae (Niño, Hernández, Correa, & Mosquera, ). AChE inhibition was described as an effect of saponins in Tribolium castaneum (Tenebrionidae) larvae, where LC 50 was 0.7 ppm (Sami, Bilal, Khalid, Nazir, & Shakoori, ). The authors of this work indicate, that sprays which they tested can be used in protection of stored food.…”

Plants are sources of numerous active substances that are used to protect crops. Currently, due to the limitations of using synthetic insecticides, plant products have attracted increasing attention as possible pesticides. In this review, we discuss some of the most interesting plant products (for example, Solanaceae, or Asteraceae extracts, Artemisia absinthium or Citrus spp. essential oils, and single compounds like α-chaconine, or α-solanine) that exhibit insecticidal activity against beetles that are pests of stored food products. Next, we describe and discuss the mode of action of these products, including lethal and sublethal effects, such as antifeedant or neurotoxic activity, ultrastructural malformation, and effects on prooxidant/antioxidant balance. Furthermore, the methods of application of plant-derived substances in food storage areas are presented.

“…In the present study, AChE activity was inhibited by the higher concentrations of C. citrinus oil. Saponins are able to inhibit AChE and the inhibition increases with increasing concentration [73]. Inhibiting AChE results in the accumulation of acetylcholine at cholinergic synapses and causes hyper excitation of cholinergic pathways [74].…”

Essential oil (EO) was extracted from Callistemon citrinus leaves by hydro-distillation. The extracted oil was analysed by GC and Mass Spectroscopy. Analysis report showed that the major constituent of the essential oil was eucalyptol (40.44%). The EO of C. citrinus exhibited 100% fumigation toxicity (adult mortality) against adult and 95.8% larvicidal activity against Tribolium castaneum at 160 μL/L (12 hrs) and 320 μL/L (48 hrs), respectively. The effective concentration of 37.05 μL/L (adult) and 144.31 μL/L (larva) at 24 and 48 hrs respectively. A 100% repellent activity was observed at 20 μl for adult beetles and 93.3% for larvae of T. castaneum at 20 μl after 24 h. Exposure to C. citrinus EO significantly reduced beetle fecundity, ovicidal activity, egg hatching, larvae survival, and emergence of adult. The effect of EO on detoxification enzymes of T. castaneum adults was examined. Results indicated that the activity of detoxification enzymes drastically varied when compared with control. This EO had toxicant effects on all stages of the life of T. castaneum. Hence it may be used as fumigant instead of the use of using synthetic chemical fumigants.

“…The adults of T. castaneum were acquired from Akbari Grain Market Lahore, Pakistan (31.5807° N, 74.3256° E) and were sub-cultured by rearing on synthetic food made from whole wheat flour and bakers' yeast with the proportion of 19:1 under laboratory conditions (Morgan et al, 2003;Amin et al, 2012;Qasim et al, 2013;Atta et al, 2020) of 28±2 °C, 60 ± 5% R.H. and 12:12 D:L photoperiod (Shafique et al, 2006;Safavi and Mobki, 2012;Qasim et al, 2013;Perez-Mendoza et al, 2014;Sami et al, 2018;Atta et al, 2020).…”

Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae) is one of the key insect pests of stored grains. Due to export regulations and zero-tolerance for alive insects in trade commodities, synthetic pesticides are often used to eliminate pest infestation in consignments. Phosphine is currently one and the only acceptable chemical used in stored grains, but due to their overuse, stored grain pests become resistant to this fumigant. There is, therefore, a great need to find alternatives. In this study insecticidal efficacy of different plant extracts viz. Ginger (Zingiber officinale), Neem (Azadirachta indica), Clove (Syzygium aromaticum) and Tobacco (Nicotiana tabacum) was compared against T. castaneum infesting stored wheat. The results have suggested that mortality and repellency in T. castaneum increased as the dose rate of crude plant extracts and exposure interval increased. The maximum mortality (86.67%) was achieved with the highest dose of crude extract of Z. officinale (80mg per 7.5g wheat) at 10 days exposure interval. Similarly, the highest dose of Z. officinale extract (80ml) was responsible to cause 100% repellency at 2 hours exposure interval. Results also suggested that grain damage and grain weight loss due to the feeding of T. castaneum decreased as the dose rate of crude plant extracts increased, while an increasing trend was found in these parameters with the increase in exposure interval. The maximum grain damage and grain weight loss (10.27% and 0.346%, respectively) were recorded at the lowest dose of A. indica crude extract at 10 days exposure interval. The result of Feeding Deterrence Index suggested that it increased as the dose rate of crude plant extracts increased while a decreased trend was found with the increase in exposure interval. The maximum feeding deterrence index (86.48%) was recorded at the highest dose of Z. officinale crude extract at 5 days exposure interval. The results of this study supported the use of Z. officinale to reduce the population of T. castaneum by its toxic and repellent characteristics which ultimately improve the grain quality of stored wheat.
