“…The perception that pesticide residues in the food supply constitute a serious health risk and the development of insecticide resistance is a big concern in agricultural production. These concerns also raise a need for alternatives to grain protectants and eco-friendly insect pest control methods among which are the use of botanical pesticides (Asawalam and Arukwe, 2004;Bekele, 2002).…”

Use of plant compounds in grain protection has shown great potential as an alternative to synthetic insecticides in Sub-Saharan Africa. This study investigated the efficacy of Eucalyptus grandis and Tagetes minuta ground leaf powders as grain protectants against Sitophilus zeamais in stored maize. Effect of leaf powders were evaluated on percent germination, percent weight loss of grain, insect infestation, grain colour and odour over 192 days (≈six months) duration. Leaf powders (2.5 and 5 g/kg), synthetic pesticide (Actellic Chirindamatura dust (0.5 g/kg)) and an untreated control were used as treatments. All plant powders significantly minimized grain damage and infestation 96 days post treatment (≈three months) and had no effect on percent germination of maize grains when compared to controls. However, variable responses dependent upon botanical plant cultivars and rate of application were observed from three to six months after application. Grain colour and odour were not affected by plant powders over six months of storage. E. grandis and T. minuta significantly reduce grain damage and insect infestation with no adverse effects on seed germination, colour and odour hence can be used as sustainable alternatives to synthetic insecticides in maize storage especially by smallholder farmers.

“…Mortality of adult bruchids was obtained by counting the number of dead bruchids in each of the translucent plastic after application of treatment and dead bruchids were removed after every count to avoid double-counting. The data were recorded after 24, 48, 72 and 96 hours according to Asawalam and Arukwe, (2004) and Jembere et al (1995).…”

The over dependence and continues use of synthetic insecticides to control storage pests have been associated with several demerits. This study was conducted to evaluate the insecticidal effect of peppermint (Mentha piperita) leaf powder on Callosobruchus maculatus. The peppermint plant was sourced locally and the C. maculatus were cultured to obtain the adult Bruchids. The peppermint was washed, dried under ambient temperature and pulverized. Complete Randomized Design was adopted for this trial with three replications of six treatment dosages of 2.5, 5.0, 7.5, 10.0, 12.5 and 0.0 g respectively of the plant material. The trial lasted for four weeks. High Bruchids mortality was observed after treatment with Mentha piperita leaf powder extract. Phytochemical screening of the test plant revealed presence of flavonoids, tannins, saponins, carbohydrates and cardiac glycosides. Descriptive statistic and analysis of variance (ANOVA) were used to analyze the data. Means (p≤0.05) were separated using Duncan Multiple Range Test (DMRT). Dosage rate and mean mortality values at the various doses were statistically significant after 48, 72 and 96 hours. The mortality could be attributed to high presence flavonoid in the Mentha piperita leaf powder. The results suggest that the leaf of peppermint has insecticidal property against adult C. maculatus. However, further trials are required to investigate effective dosage rates for other stored grains and to isolate and characterize the active flavonoids contained in the plant.

“…Between 60 and 70% of grains in Africa are reported to be stored at farm level, generally to provide a food reserve as well as seed for planting (Mobolade et al, 2019). However, maize storage conditions in developing countries are inappropriate and farmers experience post-harvest grain losses due to fungal diseases and insect pests attacks (Asawalam & Arukwe, 2004;Chukwu & Enyiukwu, 2016).…”

“…Many plant powders have been found to be very effective in the control of S. zeamais attacking maize grains in storage (Asawalam & Emosaiure, 2006). There is need to develop and adopt alternative and sustainable crop protection technologies which are eco-friendly and devoid of the obvious negative effects on non-target organisms (Asawalam & Arukwe, 2004).…”

A study was carried out to determine the efficacy of three plant materials; pawpaw (Carica papaya) seed powder, kapok tree (Ceiba pentandra) leaf powder, soursop (Annona muricata) leaf powder as well as clay and Permethrin dust against Sitophilus zeamais (Mots.) under laboratory conditions. The experiment was laid out in 5×4 factorial with 5 replicates in Completely Randomized Design in the laboratory. Maize grains weighing 50 g were treated with the plant powders, clay and the synthetic Permethrin at the rate of 0.00 g, 1.5 g, 3.5 g and 5.0 g by weight and then infested with 10 adult weevils in each vial for assessments of adult mortality, F1 emergence and damage. The comparative effectiveness of each of the treatments were assessed by counting weevils’ mortality at 14 days, 28 days, 42 days and 56 days post treatment and progeny emergence at 28 days, 42 days and 56 days post-treatment. The results were subjected to statistical analysis after transforming the data using mean percentage method and the ANOVA, the significant means were separated using the least significant differences test at 5% level. The Permethrin, a synthetic insecticide proved to be very effective followed by clay among all the treatments. Among the botanicals, C. papaya was the most effective followed by A. muricata, but were concentration dependent while C. pentandra was the least or not effective. In all trials, percentage mortality among adult S. zeamais reared on maize treated with Permethrin powders was observed to be the highest (100%) followed by those treated with C. papaya seed powder (56.6%), clay (55.5%) and A. muricata seed powder (38.8%). However, grains treated with powdered leaves of C. pentandra exhibited a low mean percentage mortality of 0.00, 0.20, 0.57 and 0.63, respectively, at different intervals post treatment which was not significantly different when compared with the untreated (control). These percentage mortality among adults were significantly (P<0.05) different from the untreated (control). Thus, all the treatments were found to significantly affect the survival of the S. zeamais at different concentration except in C. pentandra. Effect of plant powder on the emergence of adult S. zeamais was significantly (P< 0.05) different and reduced the F1 progeny emergence. The result indicated that C. pentandra had no significant effect on mortality and F1 emergence of adult S. zeamais (P< 0.05) resulting in severe damage of the grains and weight loss.
