“…All the containers were infested with 25.0 g of previously infested chickpea seeds. The level of insect infestation and grain damage was monitored after six months by quantifying the feeding deterrence index (Brari and Kumar, 2019).…”

“…After 5 and 10 days, treated grains were weighed to check the weight loss in wheat grains and recorded the data by using the formula (Atta et al, 2020). Feeding Deterrence Index (FDI) was calculated by using the formula (Brari and Kumar, 2019).…”

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.

Three plant extracts - Thymus vulgaris, Schinus molle, and Melia azedarach - were tested against adult rice weevils at 25, 50, and 100% concentrations. All extracts caused significant mortality, reaching 100% with 50-100% solutions after one day. Extracts also reduced grain weight loss, damage, and adult emergence. S. molle was effective at 25% concentration (30-44% reduction), with higher efficacy at 100% (98% reduction). M. azedarach showed similar trends (62-69% at 25%, 100% at 100%). T. vulgaris was the most effective, achieving 69-73% reduction at 25% and 100% at all levels. These results suggest significant potential for these plant extracts in eco-friendly rice weevil control programs.
