“…These farmers mix grains with different kinds of plant products for insect control (Poswal and Akpa 1991;Tapandjou et al 2000;). More than 60% of farmers in the Sahelian zone of Cameroon use plant materials to protect their maize, which is stored for an average period of 14 months .…”

Efficacy of Clausena anisata and Plectranthus glandulosus leaf powder against Prostephanus truncatus (Coleoptera: Bostrichidae) and two strains of Sitophilus zeamais (Coleoptera: Curculionidae) on maize

Powdered leaves of Clausena anisata andPlectranthus glandulosus were evaluated on Cameroonian and German strains of Sitophilus zeamais and Prostephanus truncatus for their insecticidal activities, the effects on progeny production, grain damage and population increase by admixing powders and maize grains. The two powders caused significant mortality of the three insects with P. glandulosus being far more effective than C. anisata. P. truncatus was less susceptible to P. glandulosus powder compared with the two strains of S. zeamais. The German strain (LD 50 = 2.75 g/100 g grain) of S. zeamais was less susceptible to P. glandulosus powder than the Cameroonian strain (LD 50 = 1.86 g/100 g grain). P. glandulosus unlike C. anisata powder, considerably reduced grain damage, progeny production and population increase. This study shows that there is a great potential for the powder of P. glandulosus as a promising grain protectant for integration within the subsistence farming systems of sub-saharan Africa.

“…These problems have stimulated continued interest in the re-evaluation of traditional botanical pest control agents. Plant products therefore have played an important part in traditional methods of protection against crop pests and disease vectors in Africa (Poswal and Akpa 1991). Furthermore, the rain forest contains a wide array of species, many of which are yet to be identified.…”

Studies were carried out in the laboratory to determine the efficacy of powders from plant parts of Ricinodendron heudelotii against the storage pests Sitophilus zeamais and Callosobruchus maculatus on stored maize and cowpea, respectively. Leaf, bark and root powders were added as admixtures to 100 g of grains to assess contact toxicity, damage assessment, progeny production and grain germination. Results indicated that the plant materials were toxic to the two insect species with over 30% and 75% mortality for S. zeamais and C. maculatus, respectively. Observable damage level was significantly (p ≤ 0.05) lower in treated grains while progeny production by both insect species was significantly (p ≤ 0.05) reduced. Grain germination of both crops was not affected by the powders. The potential use of P. heudelotii in storage pest management is discussed.

“…The body of scientific literature documenting bioactivity of plant derivatives to arthropod pests continues to expand, yet only a handful of botanicals are currently used in agriculture in the industrialized world, and there are few prospects for commercial development of new botanical products due to registration requirements. However, many small-scale farmers in Africa mix stored foodstuffs with different kinds of plant materials for protection against pest damage (Hassanali et al 1990;Poswal and Akpa 1991;Talukder and Howse 1995;Obeng-Ofori 2007). The use of these traditional materials has recently stimulated research to establish the scientific basis for their continued use regarding their efficacy, active constituents and effective application technology (Weaver et al 1991;RegnaultRoger et al 1993;Schmidt and Streloke 1994;Bekele et al 1995Bekele et al , 1996Obeng-Ofori et al 1997).…”

Bio-rational control of red flour beetle Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae) in stored wheat with Calneem® oil derived from neem seeds

et al. 2010

The red flour beetle, Tribolium castaneum (Herbst), is one of the most serious secondary pests that feeds on a wide range of durable stored products including cereals, cereal products and other high value produce such as cocoa beans and dried fruits. Toxicity and protectant potential of Calneem Ò oil derived from the seeds of the neem tree Azadirachta indica A. Juss. towards T. castaneum were evaluated in stored wheat in the laboratory using contact toxicity, grain treatment, persistency, progeny emergence and repellency assays. Calneem Ò contains about 0.3% azadirachtin as its major active ingredient. The Calneem Ò was applied at six dosages (0.1, 0.2, 0.5, 1.0, 2.0 and 3.0% v/v). The oil was emulsified with water using 0.07% soap. All dosages of Calneem Ò oil were toxic and highly repellent to T. castaneum with an overall repellency in the range of 52-88%. The highest dosage of 3.0% of Calneem Ò oil tested killed at least 90% of the beetles within 72 h on grain, and 88% mortality was obtained on filter paper. T. castaneum mortality was dose dependent.The development of eggs to adults on cracked wheat was significantly (P \ 0.05) inhibited by Calneem Ò oil treatments. The effectiveness of Calneem Ò oil was significantly reduced by the length of storage after application. The results obtained suggest good potential for the practical use of Calneem Ò oil as grain protectant for stored product pest control. The use of plant materials such as neem oil may be a safe, cost-effective method of grain preservation against pest infestation amongst low-resource poor farmers who store small amounts of grains.
