“…Several studies have indicated efficacy of leaf powders and essential oils of most Eucalyptus spp. against many insect species including storage pests (Muzemu et al, 2013;Rajendran and Sriranjini, 2008;Mulungu et al, 2007;Talukder, 2006;Modgil and Samuels, 1998). Eucalyptus spp leaf powders for example, were shown to protect wheat grain against insect pests (Sitophilus oryzae (L.) Coleoptera: Curculionidae), Sitotroga cereallella (Olivier) Lepidoptera: Gelechiidae) and Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae) for five months while essential oils of Eucalyptus camaldulensis and E. leucoxylon were shown to be lethal to the dates pest carob moth Ectomylois ceratoniae (Zeller) (Lepidoptera: Pyralidae) (Ben-Jemâa et al, 2013;Modgil and Samuels, 1998).…”

Use of plant compounds in grain protection has shown great potential as an alternative to synthetic insecticides in Sub-Saharan Africa. This study investigated the efficacy of Eucalyptus grandis and Tagetes minuta ground leaf powders as grain protectants against Sitophilus zeamais in stored maize. Effect of leaf powders were evaluated on percent germination, percent weight loss of grain, insect infestation, grain colour and odour over 192 days (≈six months) duration. Leaf powders (2.5 and 5 g/kg), synthetic pesticide (Actellic Chirindamatura dust (0.5 g/kg)) and an untreated control were used as treatments. All plant powders significantly minimized grain damage and infestation 96 days post treatment (≈three months) and had no effect on percent germination of maize grains when compared to controls. However, variable responses dependent upon botanical plant cultivars and rate of application were observed from three to six months after application. Grain colour and odour were not affected by plant powders over six months of storage. E. grandis and T. minuta significantly reduce grain damage and insect infestation with no adverse effects on seed germination, colour and odour hence can be used as sustainable alternatives to synthetic insecticides in maize storage especially by smallholder farmers.

“…In many countries, plant tissues or crude products of the plants, such as aqueous or organic solvent extracts, are used directly as protectants of stored products. These practices are labour intensive, but are often economically and ecologically sound, and do not require sophisticated technology (Talukder, 2006). Considering these facts, the present investigation was aimed at evaluating the toxic properties of powdered leaves of a local medicinal plant Olax zeylanica (Malla) belonging to the family Olacaeceae against Sitophilis oryzae, one of the major storage insect pests of worldwide distribution.…”

“…The efficient control as well as removal of insect pests from stored food has long been the goal of many entomologists throughout the world. Scientific literature documenting bioactivity of plant materials to insect pests shows, that a great number of plant species from a wide range of families have been assessed for their toxic, antifeedant and repellant properties (Isman, 2006;Talukder, 2006;Dubey et al, 2008;Ogunleye et al, 2010). Many of the plant species that have been investigated are often those used as culinary spices or in traditional medicine by local communities (Lale, 1992).…”

The rice weevil, Sitophilus oryzae is one of the major pests of stored rice in Sri Lanka. This study investigates the effectiveness of the botanical Olax zeylanica in controlling infestations of the rice weevil.In two separate bioassays, contact/feeding and fumigant toxicity of powdered leaves of O. zeylanica were tested against 1-7 days old adult S. oryzae under laboratory conditions. Contact/feeding toxicity was tested by directly exposing adult weevils to 1.0, 3.0, 5.0 and 7.5g of leaf powder mixed with 100g of rice grains while fumigant toxicity was evaluated by using the same doses where theadults were exposed to fumes emitted from the leaf powders. In both bioassays 100% mortality of the adult S. oryzae was observed within 18 hours of exposure to 3.0, 5.0 and 7.5g doses of leaf powder. Percentage adult weevil mortality in treated rice tested with three doses of O. zeylanica leaf powder at all the time intervals (except for 1.0g) was significantly higher (p < 0.05) than that of the corresponding control. No Contact/feeding toxicity was recorded when adult weevils were directly exposed to 1.0g leaf powder whereas only 14% adult weevil mortality was observed even after 24hours of exposure to fumes ofleafpowder. Results also revealed that mortality increased both with increasing dose and time of exposure. In both bioassays a 100% adult weevil mortality was obtained after18 hours of exposure to 3.0g leaf powder of O. zeylanica or to its fumes.Moreover, LD50 values of 2.55g and 2.08g for leaf powders obtained after 12 hours of exposure to adult S. oryzae in contact/feeding toxicity test and fumigation test respectively.The results indicatedthat leaf powder of O. zeylanica is more toxic to adults S. oryzae when they were in direct contact with it.Findings of this study bears out the exceptionally high efficacy of O. zeylanica leaves applied directly mixed with the rice grains or introduced as a fumigant to suppress weevil infestations in stored grains and strengthen the possibility of using powdered leaves of O. zeylanica as an alternative to synthetic chemicals in storage insect pest management.

“…These stored commodities are vulnerable to insects attack and the quality of food is deteriorated. It is necessary to conserve the stored food grains reserves so that the supply food remain continuous and the prices of food grains and derived products remain stable (Talukder, 2006).…”

Wheat is a major cereal in India after rice. India has emerged as the 2nd largest producer of wheat after China and accounted for 12.06 per cent share of total world production of wheat. Due to sustained efforts made by policy makers, agricultural scientists, extension workers and receptive farmers, the production of wheat dramatically increased manifold on account of adoption of modern production technology. A considerable amount of wheat as well as other grains is lost every year in storage due to biotic and abiotic factors. Stored wheat grains are subjected to the attack of many pests and diseases in storage. There are approximately 200 species of insects and mites attacking stored grains and stored products. Insects are a foremost cause of losses to wheat grain and ultimately to producers as a result of direct feeding or as carriers or vectors of certain diseases. Severe insect infections surely cause weight losses and deteriorate kernel quality, which can range from limited to state-wide in scope. The red flour beetle, Tribolium castaneum (Herbst) is worldwide and most destructive pest of stored products and is cosmopolitan in distribution. It is the most common pest of wheat flour.Many indigenous plants have been used against insect pest of stored grains and other crops in India. Over 120 plants and plant products can be used for the control of stored grain insect pests. Piper nigrum and Zingiber officinale play defensive role against infections by microbes, insects and animals. Thus, the present study provides a comprehensive account of
