Indigenous Materials

The experiment was conducted to evaluate the effect of some containers, chemicals and indigenous materials for protection of wheat seed in storage at the Entomology Laboratory of Sher-e-Bangla Agricultural University (SAU), Dhaka. Wheat seeds were stored in four types of containers (Tin kouta, earthen pot, plastic container and gunny bag) with two types of chemicals (Naphthalene and camphor) and two indigenous materials (neem leaf powder and sand). Among the different containers, the lowest population of grain moth (1.40-7.93), red flour beetle (6.40-35.33) and rice weevil (0.20-9.13) was recorded from the plastic containers. At the initial stage of storage, grain moth was dominant but red flour beetle was abundant at the middle and later stage of storage. Population of rice weevil was gradually increased with storage period. Considering the storage materials, the lowest population of grain moth (3.92-28.98), red flour beetle (7.58-43.08) and rice weevil (0.75-9.08) was found in naphthalene. Camphor had the similar population level of those three insect pests during the study period. Key words: Grain moth; rice weevil; red flour beetle; neem leaf powder; camphor; naphthalene.

Red Flour Beetles

Runner variety peanuts treated with four rates of diatomaceous earth (28.4, 56.8, 85.2, and 113.6 g per 12.7 kg peanuts) and Virginia variety peanuts treated with four Bacillus thuringiensis formulations (Dipel, Foil, M-Trak and Trident) were held for 8 months at ambient conditions in south Georgia and infested with stored-product insect pests. No red flour beetle, Tribolium castaneum (Herbst), adults were found in peanuts treated with diatomaceous earth until six months after treatment. After 8 months, red flour beetle populations in peanuts treated with diatomaceous earth ranged from 5.7 ± 1.9 to 32.8 ± 12.0 per kg, as compared to 221.2 red flour beetles per 12.7 kg peanuts in untreated controls. The effect of diatomaceous earth on red flour beetles was described by non-linear regression. Indianmeal moth, Plodia interpunctella (Hübner), and almond moth, Cadra cautella (Walker), populations were not abundant in untreated controls or the diatomaceous earth treatments. After 8 months, red flour beetle populations in peanuts treated with the four biological insecticides were not significantly different from the untreated controls. Low levels of Indianmeal moth and almond moth were present in all treatments.

Leaf Powder

A laboratory experiment was conducted to assess the efficacy of nine plant products namely neem, karanj, eucalyptus, lantana, custard apple, lemon grass and meetha neem using their leaf powder and turmeric and ginger using their rhizome powder against the rust red flour beetle. Tribolium castaneum in stored wheat. Among the different treatments of plant products were evaluated by treating 100 g of wheat grains with 2% of grain weight against T. castaneum up to 30 days. The grains treated with eucalyptus leaf powder were found to be most effective and 27.25% adult mortality and 0.09% weight loss was observed. The least effective treatment was custard apple leaf powder with 7.78 % mortality and lantana leaf powder where 0.37% weight loss was recorded.
