“…Each plant powder was evaluated at four rates (2,5,7, and 10% w/w) and commercial synthetic insecticide Antouka (Permethrin 3 g/kg + pirimiphos 16 g/kg; DP) included as a positive control. Treated and untreated yam chips (10 g) were alternately placed equidistantly from the center of the circular base [20]. The treatments were arranged in a completely randomized block design with four replicates per concentration.…”

Dinoderus porcellus is considered as the most important pest of stored yam chips and compounds extracted from plants can be used for its control. The present study aimed to test the insecticidal and repellent activities of powders and extracts of leaves of Bridelia ferruginea, Blighia sapida, and Khaya senegalensis against D. porcellus. The efficacy of plant powders was compared with the synthetic pesticide Antouka (Permethrin 3 g/kg + pirimiphos 16 g/kg). The results of the experiment revealed that all plant powders were effective as repellents. Antouka was more effective as insecticidal than the plant powders and minimal weight loss was observed with B. sapida at 2%. Among treatments, propanol extract of K. senegalensis at 5% was found to elicit the highest repellent effect on D. porcellus. The LC 50 results revealed that the acetone extract of K. senegalensis is the most toxic (0.29 L/insect) to the pest, while the propanol extract of B. ferruginea at 5% exhibited strong fumigant toxicity against D. porcellus, with 88.89% of pest mortality at 160 L/L air. The findings from the current work proved that plant powders and extracts of the three plants are sources of botanical insecticides which may be used in the integrated management of D. porcellus.

“…The experiment was carried out following the methodology used by Chebet et al [20]. Leaf powders of the different plants were admixed with 100 g of disinfected yam chips in plastic jars (13 cm in diameter by 10 cm in height) at, respectively, rates (% w/w) of 0, 2, 4, 6, 8, and 10.…”

“…In addition, active phytochemicals such as alkaloids have been found to disrupt growth and reduce larval survival by hindering loss of exoskeleton during larval development [47]. Other active principles such as isoflavonoids, flavonoids and terpenoids have also been reported to inhibit reproduction and fertility among coleopterons [29,48].…”

“…Bioactivity of plant extracts on adults Sharma (1999) reported that neem seed, neem kernel powder at 4 % and neem leaf powder at 5 % concentration protected maize for 5 months against S. oryzae, S. cerealella, R. dominica and T. castaneum. Also many studies have shown the effectiveness of neem against storage insects of maize (Huang and Ho 1998;Mulungu et al 2007;Sule et al 2012;Chebet et al 2013).

Natural products derived from plants are emerging as potent biorational alternatives to synthetic insecticides for the integrated management of post harvest insects of maize. In this paper, effectiveness of botanicals including plant extracts, essential oils, their isolated pure compounds, plant based nano formulations and their mode of action against storage insects have been reviewed with special reference to maize. Plant based insecticides found to be the most promising means of controlling storage insects of maize in an eco friendly and sustainable manner. This article also throws light on the commercialization of botanicals, their limitations, challenges and future trends of storage insect management.
