“…The abovementioned results are in agreement with those of Zewde and Jembere (2010) who evaluated the efficacy of products of orange (Citrus sinensis) peels for controlling the stored products beetle Zabrotes subfasciatus (L) in stored haricot beans. Powders from ground peels caused significant reduction in progeny emergence of Z. subfasciatus (P< 0.05).…”

Five botanical fine dusts, ash and sulfur powders were tested for their biological performance activity against the rice weevil Sitophilus oryza. Their toxicities and delayed effect on the treated insect were determined. The insect was exposed to treated rice grain with each of the evaluated materials and bioassayed for different intervals extended form 3 to 30 days. The insecticidal activity was expressed in terms of the adult insects-mortality due to the contact with the tested materials. The effect of these materials on the inspected damage in rice grains and/or resulted F 1 progeny post-treatment had been investigated and expressed in terms of productivity inhibition percentage (PIP).The complete control of treated insects (100% kill) was recorded at the doses of 0.25 and 0.5 g of black pepper fine dust/50 g rice grains after 21 and 14 days post exposure, consequently. Furthermore, at the higher dose of 0.5 g material/50 g rice grains, camphor and black pepper pronounced complete control of the exposed adult-insects giving 100% kill after an exposure period of 30 days, while Latania fine dust was the least efficient tested material.The results were also confirmed by the deduced dependent positive strong relationship between the recorded insect mortality and the time needed to cause 50 % kill of the exposed insects (LT 50 ) at all the different used doses. Based on LT 50 values, the superior insecticidal effect was recorded for black pepper, followed by orange peel, then camphor and the other tested materials. Meanwhile, clove and Latania fine dusts were the least efficient materials at all used doses (w/w).The results proved that camphor fine dust was the most potent material in preventing grains perforation and reducing the damage that can be caused by the adultweevils of S. oryzae followed by black pepper fine dust. Although, the clove fine dust was less toxic, it showed a potent delayed and completely inhibited the raise of F 1 progeny post-parents treatment (100%) at its higher tested dose of 0.5 g powder /50 g rice. There was also a good correlation between the insecticidal activity of black pepper fine dust, either picked up or contacted the exposed insects and its effect on prevention or reduction of grains damage and/or its ability in suppressing the raised individuals of F 1 progeny.

“…To these authors' knowledge, there are no studies about fumigant effects of essential oil of this variety (hamlin) of C. sinensis on insects. Zewde and Jembere (2010) studied the effect of C. sinensis essential oil on Zabrotes subfasciatus L. and showed that C. sinensis had contact toxicity on this insect pest.…”

Plant materials with insecticidal properties have been traditionally used for generations in some parts of the world. In this study, fumigant toxicity of some essential oils extracted from Rosmarinus officinalis L., Mentha pulegium L., Zataria multiflora, and Citrus sinensis (L.) Osbeck var. hamlin on adults of stored-product pests, including . Results showed that among tested essential oils, C. sinensis var. hamlin had good fumigant toxicity on T. castaneum, S. granarius, and C. maculatus. In addition, M. pulegium essential oil was stronger than C. sinensis var. hamlin on S. granarius. Results also indicated that both Z. multiflora and R. officinalis had fumigant toxicity on P. interpunctella adults. In summary, results indicated that these essential oils have good fumigant toxicity on stored-product pests.

“…Then the numbers of F1 progeny produced by the experimental insects were counted. Counting were stopped after 56 days from the day of introduction to avoid overlapping of generation following similar procedures of previous scientists (Gebre Selase and Getu, 2009;Zewde and Jembere, 2010).…”

Dosage rates of 0.625, 1.25 and 2.5% of the leaves powder of Calpurnia aurea and Milletia ferruginea, and red and white inert dusts that were admixed with the 100 g of three resistance maize varieties were tested as protectant against maize weevils under laboratory condition. Significantly (p < 0.05) higher parental adult weevil's mortality were recorded in all treatments of integration than untreated check at almost all days (except first day) after treatment. Mortality effects of the tested integrated components were also increased both with increased dosage and days after treatment. The mortality also became 100% in all treatments of integration applied at all rates, following 12 days of treatment application likewise the positive control. All treatments of integration applied at all rates also induced significantly (P < 0.05) higher (≥ 60.31%) protection of maize grains against F1 progeny emergence, grain damage (≤ 6.67) and weight loss (≤ 1.12) by S. zeamais than negative control. Besides, 100% inhibition of F1 progeny emergence, no percent grain damage and weight loss of maize grains were also observed in all of the three treatments of integration applied at dosage of 10% likewise also for that of the positive control. Therefore, integration of the aforementioned botanicals and inert dusts with resistant varieties applied at 2.5% and above (5 and 10%) rates were potent in preventing maize grains against maize weevils attack and could be used in the management of maize weevils as ecologically sound, safe and cheap weevil's management alternatives under farmer's storage conditions.
