“…A redução da emergência de S. zeamais pode estar relacionada ao efeito tóxico dos óleos ao embrião do inseto, em virtude da privação de oxigênio (SCHOONHOVEN, 1978), mas é de se esperar que essa toxicidade seja reduzida com o tempo, devido a sua baixa persistência (ISMAN, 2006). Essa informação, em relação à redução da emergência com o prolongamento do período de armazenamento, foi comprovada em pesquisas desenvolvidas por diversos autores (COITINHO et al, 2006;ASAWALAM & HASSANALI, 2006;DEMISSIE et al, 2008).…”

“…Many tropical medicinal plants have been used as pest control agents (Schoohoven 1978, Singh et al 1990, Lale 1992. Peasant farmers and researchers often claim successful use of plant materials in insect pest control including ash (Ofuya 1986, Ajayi et al 1987, vegetable oil, spices and plant powders or extracts (Ajayi et al 1987Lajide et al 1998).…”

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

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.

“…Farmers and researchers often claim the successful use of plant materials in insect pest control, including ash (Ofuya, 1986;Ajayi et al, 1987), vegetable oils (Schoovoven, 1978), plant extracts (Talukdar and Howse, 1993;Adedire and Lajide, 1999), and botanical powders (Abdullahi and Efficacy of Acorus calamus L. leaves and rhizome on mortality and reproduction of Callosobruchus chinensis L. (Coleoptera: Bruchidae) Muhammad, 2004;Shukla et al, 2007). It has been reported that certain plant preparations and traditional methods are much safer than chemical insecticides (Verma and Dubey, 1999;Weaver and Subramanyam, 2000); therefore, these materials should be explored to protect stored products against pest infestation.…”

Laboratory and field experiments were conducted to investigate the bioefficacy of sweet flag (Acorus calamus) against the pulse beetle Callosobruchus chinensis, which infests stored chick pea seeds. Dried powders of the leaf and rhizome as well as their extracts in methanol (ME) and petroleum ether (PEE) were evaluated as bio-insecticides against the beetle. Rhizome powder (5 mg/g seed) was found to be more efficacious, causing 100% mortality, than leaf powder (20 mg/g seed), showing 91.1% mortality. Rhizome powders also showed 100% ovicidal activity and thus completely inhibited F 1 emergence at a lower dose than that of leaf powders. The ME and PEE of leaves and rhizome showed 12 to 100% mortality. The percentage of egg laying decreased from 12.8 to 100 with increasing doses of powders and extracts. No F 1 adult emerged at 0.3-0.4 mg/g ME of leaves and rhizome and PEE of rhizome. In six-month field trials, all treatments at laboratory doses proved efficacious (75-98%) over organophosphate insecticide malathion (74.4%) in terms of feeding deterrence. Powder-and extract-treated chick pea seeds did not lose their viability and germinated at 100%, similar to control seeds. It was concluded that leaf and rhizome powders and their solvent extracts showed significant mortality, and inhibition of egg laying and F 1 emergence of C. chinensis at varying concentrations. Hence, the leaves and rhizome of A. calamus may be recommended as admixtures in the integrated management of beetle infestation of pulse seeds during storage.
