“…The various cashew (A. occidentale) balms coated with the kaolin powder would have like mode of action to prevent any contact with the cowpea grains treated, thus causing the inanition. These results corroborate those reported by Kemabonta andFalodu (2013, Oparaeke andBunmi (2006), and Ileke et al (2014), in which they reported that oil and powder coming from cashew (A. occidentale) have caused 100% of mortality of maize weevil Sitophilus oryzae to 96 h after treatment of Forim et al (2012) reported that the high rate of mortality observed with the use of plants extracts would be linked to secondary metabolites usually contained in the plants, which have high toxic effects on the insects. Other authors (Adedire et al, 2011;Ileke and Olotuah, 2012;Ileke et al, 2014) reported that the powder and oil of cashew could influence the movement and the mating of the adults insects, and could also cause the locomotion inhibition of the adults insects, thus reducing their lifespan.…”

In this study, the bioefficacy of the powdery formulations were evaluated. Thus powdery insecticide Antouka®, kaolin powder and powdery formulations based on kaolin powder and various cashew balms were tested against, cowpea bruchid in storage. For each balm, it was formulated 10 g of powdery formulation, which were obtained with 10 g of kaolin and 1 mL of cashew balm. Antouka® insecticide was applied at recommended dose; powdery formulations were tested at 0.5 g; 1 g, for 50 g of cowpea seeds in jars. Twenty (20) cowpea weevils at 24 h old were introduced in each jar. The jars, covered with wire mesh, were kept outdoors during forty five (45) days using a randomized block design with four replicates. Therefore, parameters of mortality and F 1 progeny of Callosobruchus maculatus, weight losses, seeds damaged and germination rate were assessed. Results obtained indicated that Antouka® insecticide and the formulated powders caused a significant mortality rate and improved the germination rate of seeds. Nevertheless, the cold extracts had less seeds damaged than hot extracts. F 1 progeny decreased with increased dose, (25.50±7.96 insects to 44.50±7.67 insects for 0.5 g; and 11.25±4.62 insects to 29.50±3.22 insects for 1 g). According to calculated LD 50 and their confidence intervals, formulated powders have significant toxicity on C. maculatus. These results revealed the bioefficacy of powdery formulations. They can be recommended as alternatives insecticides.

“…Some researchers who had earlier evaluated plant oils as botanical insecticides and grain protectants had found them to be effective against storage beetles (Oparaeke et al 2001, Oparaeke & Bunmi 2006. The results from this investigation are similar to the observations of Onolemhemhem & Oigiangbe (1991), who obtained 100% mortality of adult C. maculatus in cowpea seeds treated with groundnut oil at the rate of 5 ml and 6 ml of oil kg -1 .…”

Response of Callosobruchus maculatus (Coleoptera: Chrysomelidae: Bruchinae) to extracts of cashew kernels

et al. 2011

Cashew kernels were extracted with six different solvents namely methanol, ethanol, water, acetone, pet-ether and n-hexane. The different extraction products were evaluated on C. maculatus adults for their mortality, ovicidal and adult emergence effects. The long-term protectant ability of the cashew kernel extracts and water absorption capacity of the treated cowpea seeds were also investigated. The results obtained showed that the steam distillate was most toxic to C. maculatus. The least toxic extracts on the insect were those of methanol and ethanol. The extracts drastically reduced oviposition in C. maculatus. The cowpea seeds treated with steam distillate had the lowest water absorption capacity, while the highest water absorption capacity was obtained in grains treated with ethanol and methanol. At 2.0% v/w cashew kernel extracts, the percentage water absorption capacity of cowpea seeds increased with increase in the interval of submergence.Steam distillate and the extracts of n-hexane, pet-ether and acetone completely prevented infestation and damage of the treated cowpea seeds for a period of three months as there was neither weight loss nor damage in the treated grains. In the grains treated with the methanol and ethanol extracts, damage of 20.17% and 9.76% were recorded, respectively. The results obtained from this study revealed that extract of cashew kernel is effective in controlling cowpea storage bruchid, C. maculatus and could serve as an alternative to synthetic insecticides for the protection of stored cowpeas against bruchids.

“…The powder and oil of A. occidentales was also very toxic to the survival of S. cerealella: no adults emergedfrom eggs treated with oil. Many researchers have reported the insecticidal and ovicidal effects of A. occidentales extract against Callosobruchus species (Oparaeke & Bunmi 2006;Adedire et al 2011;Ileke & Olotuah 2012). The mode of action could be that the powder or extract coat the treated wheat grains, preventing contact between the grains and adult moth, leading to starvation.…”

Powders and extracts prepared from Capsicum frutescens, Cymbopogon citratus, Moringa oleifera, Anacardium occidentale were tested for their insecticidal potential against Angoumois grain moth, Sitotroga cerealella. The powder of C. frutescens had the highest mortality rate of 100% after 2 days of application at all tested concentrations. The extracts killed all the adult moths introduced at all tested concentrations. The survival of the moth from egg to adult when treated with the plant powders showed significantly greater mortality. Extracts of all the tested plants were toxic to adult moths and also prevent hatching of the eggs of S. cerealella..
