Powders from three medicinal plants were evaluated for their efficacy as contact and fumigant insecticides on cowpea bruchid, Callosobruchus maculatus (Fab.) in the laboratory at ambient tropical conditions of temperature and relative humidity. The plant powders tested included Capsicum frutescens L. (fruit and seed), C. annum Miller (fruit and seed) and Citrus sinensis Osbeck (peel). The powders were applied at rates 0.0 (control), 2g and 3.0g/20g of cowpea seeds either directly for contact…

Effect of Plant Powders on Survival, Oviposition and Progeny Development of Callosobruchus Maculatus for Protection of Leguminous Seeds during Post Harvest

All the tested plant powders were toxic to cowpea weevil thus could be applied by farmers by mixing withcowpea seeds to avert hatching of the eggs and development of larva, a destructive stage for management of insects and maintain nutritional and seed value in cowpeas.


The results indicated that P. guineense seed oil has protectant potential against insect pest damage in storage and a good alternative to synthetic insecticides in the control of insect pest of stored products.

Chemical composition and insecticidal effect of fruit peel powders of two citrus species against Callosobruchus maculatus (F.) (Coleoptera: Bruchidae) in stored cowpea (Vigna unguiculata)

Overall results indicate high potential of both Citrus species, particularly C. nobilis as a repellent, toxicant and growth inhibitor to reduce the damage caused to leguminous crops by C. maculatus.

Contact and fumigant toxicity of five pesticidal plants against Callosobruchus maculatus (Coleoptera: Chrysomelidae) in stored cowpea (Vigna unguiculata)

These plants may, therefore, serve as effective but less harmful biopesticide alternatives to Actellic and should not be promoted for controlling bruchids in cowpea.

Pesticidal Efficacy of Four Botanical Pesticides on Survival, Oviposition and Progeny Development of Bruchid, Callosobruchus maculatus in Stored Cowpea, Vigna unguiculata

The bioactive compounds from these plants offer great potential of developing botanical pesticides against postharvest insects in stores, and selected botanicals (Tephrosia vogelii, Chenopodium ambrosioides, Tithonia diersifolia, Lippia javanica and Vernonia amygdalina) are selected.

Evaluation of the Efficacy of Plant Powders, Cow Dung Ash and Malathion Dust against Callosobruchus Chinensis L. (Coleoptera: Bruchidae) On Chickpea in Jole Andegna: Southern Ethiopia

Looking in to the side effects of synthetic pesticides, it is suggested that the locally available plant powders and cow dung ash can play an important role in protection of chickpea during storage against invasion by bruchid.

Protectant Effect of Vegetable Oils against Cowpea Weevil (Callosobruchus maculatus) on Stored Cowpea [Vigna unguiculata (L.) Walp]

The 8 ml/kg of cotton seed, groundnut and sesameoils investigated are promising bio friendly preservatives that could serve as an alternative formulations to synthetic chemical based insecticides for storage of cowpea.

Efficacy of Some Plants as Insecticide Against Callosobruchus maculatus Reared on Black Gram Seeds

: Plant extracts/powders have potential to employ as promising and encouraged alternatives to synthetic insecticides in controlling stored grain pest. During present study, trials were carried out



Evaluation of Contact Toxicity and Fumigant Effect of Some Medicinal Plant and Pirimiphos Methyl Powders against Cowpea Bruchid, Callosobruchus maculatus (Fab.) [Coleoptera: Chrysomelidae] in Stored Cowpea Seeds

Contact toxicity assay show that A. indica and P. guineense powders have a comparative effect to synthetic insecticide, Pirimiphos methyl, while in the fumigation assay, none of the plant powders was suitable as a fumigant.

Products derived from the leaves of Ocimum kilimandscharicum (Labiatae) as post-harvest grain protectants against the infestation of three major stored product insect pests

Ground leaves and the essential oil protected the grains against feeding by all three species, resulting in lower weight loss and number of damaged seeds compared with untreated grains, and protection against loss due to insects in traditional grain storage in developing countries.

Evaluation of Seed and Fruit Powders of Capsicum annum and Capsicum frutescens for Control of Callosobruchus maculatus ( F . ) in Stored Cowpea and Sitophilus zeamais ( Motsch ) in Stored Maize

Capsicum annum and Capsicum frutescens fruit and seed powders were evaluated in the laboratory for the control of Callosobruchus maculatus (F.) in stored cowpea and Sitophilus zeamais Motschulsky in

Evaluation of Seed and Fruit Powders of Capsicum annum and Capsicum frutescens for Control of Callosobruchus maculatus (F.) in Stored Cowpea and Sitophilus zeamais (Motsch) in Stored Maize

This paper highlights the potential of C. frutescens and C. annum seed powders as seed protectants against the test bruhids at higher rates, than their ineffective fruit powders in all parameters assessed.

Toxicity of some plant powders to maize weevil, Sitophilus zeamais (motschulsky) [Coleoptera: Curculiondae] on stored wheat grains (Triticum aestivum)

Seed powders of Alstonia boonei can be used as a good alternative to pesticides against S. zeamais in addition with that of A. indica which effects are well established by many former works and are suitable for consumption and planting stock.

Use of nutmeg Myristica fragrans (Houtt.) powder and oil for the control of cowpea storage bruchid, Callosobruchus maculatus Fabricius

Both nutmeg oil and powder are effective bio-insecticides against C. maculatus and could be incorporated into pest management of stored cowpeas since the products are edible and ecologically safe.

Laboratory evaluation of four medicinal plants as protectants against the maize weevil, Sitophilus zeamais (Mots)

The petroleum ether extract of four medicinal plants; Aristolochia ringens (Vahl), Allium sativum (L), Ficus exasperata (L) and Garcinia kola (H), were evaluated as grain protectant against the maize

Insecticidal activities of two powdered spices, black pepper and red pepper on adults of Rhyzopertha dominica (F.) and Sitophilus granaries (L.).

This plant powders exhibited promising potential in protecting wheat grains against two species of insects, and caused complete reduction in Fl progeny emergence of R. dominica at highest tested dosages.

Laboratory evaluation of the toxic properties of forest anchomanes, Anchomanes difformis against pulse beetle Callosobruchus maculatus (Coleoptera: Bruchidae)

Investigation of the efficacy of crude stem extracts of forest anchomanes, Anchomanes difformis, against the pulse beetle Callosobruchus maculatus found that at the highest application rate, the plant extract provided good protection to grains stored for 90 days.
