“…Available laboratory results indicate that botanical insecticides, derived from leguminous plants, are promising tools to protect grain from stored product insects (Fields et al 2001;Hou and Fields 2003;Kumar et al 2004;Fields 2006). In this study, we observed that the application of been flour in wheat grain was effective only against some stored product mites.…”

Stored product mites are pests of serious economic and medical importance. Recently, it has been shown that the biological control of these pests based on the use of natural compounds and predators had a high potential for success. In this study, we investigated the suppression of three pest mites by combination of the predator Cheyletus malaccensis Oudemans, 1913 and bean flour (Phaseolus vulgaris), which is an antifeedant. Wheat grain (100 g) was contaminated with 100 individuals (Acarus siro (Linnaeus, 1758), Aleuroglyphus ovatus (Troupeau, 1878) or Tyrophagus putrescentiae (Schrank, 1781)). We added bean flour in concentrations of 0, 1, 5 and 10 g kg -1 (wt/wt) and/or the predator with initial predator/prey ratios 0, 1/50, 1/25 and 1/10. The experiment was carried out under abiotic conditions that are optimal for pest development. After 21 days, pest and predators numbers were recorded. Application of flour significantly reduced populations of A. siro, slightly reduced populations of T. putrescentiae, the efficiency increased with increasing concentration. A. ovatus was not affect by bean flour. Populations of all mite species were successfully reduced by the sole addition of C. malaccensis, with a higher efficiency at higher Cheyletus ratios. The additive effect of the predator and flour was mainly apparent in the reduction of T. putrescientae. The population of C. malaccensis was not affected by the presence of bean flour. It is therefore recommended to use bean flour for the reduction of A. siro, a combination of bean flour and Cheyletus for the reduction of T. putrescientae, and only Cheyletus for the reduction of A. ovatus.

“…This was confirmed by the work of Hou et al (2004), who noted that the wheat treatment with the pea flour enriched with protein, at a concentration of 0.04-0.1%, reduced the Sitophilus oryzae L. population of 26 and 79%, respectively and Cryptolestes ferrugineus of 27 and 43%, respectively. To a concentration of 1%, the death rate of Sitophilus oryzae L. reached 100% for 3 weeks on rice (Pretheep- Kumar et al, 2004). In addition, to the efficiency of the pea protein on reducing populations of Cryptolestes ferrugineus, Sitophilus spp., Tribolium castaneum and Tribolium confusum, Fields et al (2001) noted that it is also repellent to concentrations of 0.1 and 1%, after 1 h of exposure.…”

“…In addition, to the efficiency of the pea protein on reducing populations of Cryptolestes ferrugineus, Sitophilus spp., Tribolium castaneum and Tribolium confusum, Fields et al (2001) noted that it is also repellent to concentrations of 0.1 and 1%, after 1 h of exposure. This repulsion is about 91.2% after 48 h of Sitophilus oryzae L. exposure to the treated rice at a concentration of 1% (Pretheep- Kumar et al, 2004). However, Hou et al (2006) showed that the toxins of protein-rich pea flour can cross the insect cuticle and therefore the midgut tissue will be damaged with the presence of several gas bubbles.…”

“…The insecticide effect of pea flour on rice weevil (Sitophilus oryzae L.) have received the most attention (Hou and Fields, 2003;Pretheep-Kumar et al, 2004;Fields, 2006). Pea protein is repellent to several stored-product insects (Fields et al, 2001;Kumar et al, 2004) and toxic (Pretheep-Kumar et al, 2004). This toxicity is primarily correlated with the biological activity of a major albumin isolated from pea grains, pea albumin1 subunit b (PA1b) (Gressent et al, 2003).…”

The aim of this study was to evaluate the toxicity of pea albumin 1 subunit b (PA1b) homologous against granary weevil (Sitophilus granarius L.). Adults of less than 5 days were maintained at 27±0.2°C and 70±5% relative humidity, on bread wheat (Triticum aestivum L. subsp. Aestivum) flour dumplings (control) and on pea flour, chickpea, bean, lentil, broad bean (toxic) during 15 days. The concentrations of used pea flour were 10, 20, 40, 60 and 80%. On PA1b reference: Pea/wheat with 80% pea flour, we have observed on the 3rd day, a mortality rate over 10%. From 7 days there were no survivors. For concentrations of 40 and 60%, the mortality rate was 73 and 93%, respectively; but at 10 and 20% of pea, the rate was low not exceeding the 20% threshold. A significantly positive correlation (R 2 = 0.91) was observed between the concentration of pea flour extract and the mortality rate of Sitophilus granarius L. The linear regression of semi-logarithmic curve is highly significant (p = 0.012, <0.05) and allow to determine the LD 50 of which is 25.63±3.26% or 64.075±8.14 mg. At the maximum concentration of 80% on lentil, bean and broad bean, there was a total mortality of the insect at 7 days; others are less toxic such as pea with 30% and chickpea, whose mortality rate does not exceed the 23% threshold. Furthermore, complete mortality of the insect was observed after 14 days in all grain legumes.

“…The glass bioassay technique (Mohan and Fields, 2002) determines the response of insects to potential repellents by specifying the number insects that were kept away from treated source or grain (Pretheep et al, 2004). In this technique, leaky plastic glasses with equal pores were used that allow only insects and not grain to pass through.…”

To alleviate insect pest problems in storage, synthetic pesticides are recommended; but their use may create toxicity to non-target organisms, development of resistance and residues in treated products. Under such circumstances, the need for research to find a safe, convenient, durable and economically logical method is necessary. The application of repellents could be considered as a new control method in storage. In this study, percentage repellency (PR) of Sirinol (garlic emulsion) was assayed on adults of cigarette beetles, Lasioderma serricorne (F.) and red flour beetles, Tribolium castaneum (Herbst) using three techniques, Petri-dish, Y-shape olfactometer tube and leaky glass. The insects were exposed to 0, 0.5, 1.5 and 10% concentration of Sirinol that is a botanical compound and PR of the adults was determined. In each of the three methods, the maximum PR of Sirinol was about 10% concentration, and the quantities were equal to 58.56, 42.58 and 26.29% for L. serricorne and 70.99, 55.47 and 38.72 for T. castaneum in Petri-dish, Y-shape olfactometer tube and leaky glass techniques, respectively. The interaction between concentration and time (concentration × time) was not significant for the adults of the two species. It was shown that T. castaneum was more susceptible to Sirinol than L. serricorne. Data analysis revealed that PRs of Sirinol were not significantly different between the time of 12 and 72 h.
