Effect of Ten Insecticidal Plant Powders on Rice Weevil, Sitophilus oryzae L. and Grain Weight Loss in Stored Sorghum

Protecting Rice Grains from Sitophilus oryzae L. Infestation using Plant Extracts under Controlled Conditions

“…In general, the effectiveness of plant extracts stems from the presence of anti-nutritional compounds that deter egglaying or prevent hatching, thereby reducing adult emergence or affecting insect development and longevity. These findings align with the observations of several researchers [13,[15][16][17][18].…”

“…Furthermore, the extracts demonstrated efficacy in reducing grain weight loss and the percentage of grain damage by inhibiting insect activity and feeding. Govinden K, et al [17] reported that grain weight loss in S. oryzae-infested grains treated with A. indica extract was minimal, at 13.01%, compared to the untreated control, which exhibited a significant loss of 49.22%, after 60 days of treatment [17]. These findings align with the growing interest in exploring environmentally friendly alternatives to synthetic insecticides for controlling rice weevil infestations.…”

“…Several studies have also demonstrated that the effectiveness of M. azedarach stems from the presence of bioactive compounds with anti-nutritional and insecticidal properties. These compounds include triterpenoids and limonoids found in the leaves and fruits of M. azedarach, as well as azdrechtin [14][15][16][17][18].…”

Evaluation of the Efficiency of the Biocide Oxymatrine in Controlling the Different Roles of the Saw-Grain Beetle Oryzaephilus surinamensis (L.) (Silvanidae: Coleoptera) in the Laboratory

“…The plastic containers were covered with muslin cloth and tied with rubber bands for ventilation and to prevent insects from escaping. Then the containers were placed in the incubator at a temperature of 28 ± 2 C and a relative humidity of 50 ± 5%, and after passing (1,3,5,7,9,11,14) days of treatment were calculated corrected percentages of loss.…”

“…Cereals and other crops play the same role in human food [2] as it is the basic food for more than 70% of Asian peoples, including India. It is a source of livelihood for about (120-150) million rural households [3]. And rice, Oryza sativa, is at the forefront of cereals, as it is considered one of the basic foods for most of the people of warm tropical and subtropical countries and constitutes the main food for more than half of the globe's population [4].…”
