Abstract

Rhyzopertha dominica is a highly destructive insect pest that inflicts severe damage on stored wheat grains all over the world. Recently, botanical pesticides have emerged as an eco-friendly alternative to synthetic chemicals. This study was carried out to determine the toxicity of leaf powders obtained from different plants are Lantana camara Curcuma longa, Callistemon citrinus, Melia azadirechta, Azadirechta indica, Murrya koenigii, Eucalyptus citirodora, Ocimum sanctum, Ageratum conyzoides, Chenopodium album, Trigonella foenum, Andrographis peniculata, Allium sativum, Jatropha curcas, and untreated wheat seed as a control in the control of R. dominica infestation on stored wheat grains. When four doses (5.00, 7.00, 10.00, and 12.00 g) per Kg seed of all the treatments were applied to wheat grain, it resulted in zero adult emergence and complete inhibition in both Preliminary and Confirmatory tests. This indicates their strong effectiveness against the lesser grain borer in stored wheat. In contrast, the untreated grain displayed an emergence (37.26) and an inhibition percent (29.62)

Conclusion

In recent years, the use of synthetic insecticides in the fight against agricultural pests has inflicted unintended damage on both human life and the environment. Plant materials with insecticidal properties have been traditionally used for generations in some parts of the world. These studies provide an interesting opportunity to develop bioinsecticides, repellents, and antifeedant formulations based on the extracts from plants. When various doses of all the treatments were applied to wheat grain, it resulted in zero adult emergence and complete inhibition in both early and later tests. This indicates their strong effectiveness against the lesser grain borer in stored wheat. In contrast, the untreated grain displayed an emergence (37.26) and an inhibition percent (29.62).
