Experiments were carried out to evaluate the toxicity of six botanicals, Bazna (Zanthoxylum rhetsa), Ghora-neem (Melia sempervirens), Hijal (Barringtonia acutangula), Karanja (Pongamia pinnata), Mahogoni (Swietenia mahagoni) and Neem (Azadirachta indica) against red flour beetle, Tribolium castaneum Herbst. Leaf and seed extracts were prepared by using acetone, methanol and water as solvents. The results showed that extracts of all the six plants had direct toxic effect on red flour beetle. Among them, Neem seed extract showed the highest toxic effect (mortality, 52.50%), whereas Hijal leaf extract possessed the lowest toxic effect (mortality, 22.24%). Among the solvents, acetone extract showed more toxic effect than other extracts. Seed extracts of respective plants were slightly more toxic than leaf extract. The effectiveness of most of the plant extracts increased proportionally with the increase of doses and decreased with time.

Studies were conducted in the Seed Pathology Laboratory, Department of Plant Pathology, Sher-e-Bangla Agricultural University to evaluate some indigenous plant extracts on the incidence of Bipolaris sorokiniana of wheat and seed germination. Seed treated with plant extracts reduced the incidence of Bipolaris sorokiniana. The lowest incidence was counted (12.33%) in seeds treated with Burmuda grass extracts (1:2W/V). While the highest seed germination (99.60%) was recorded in seeds treated with this grass extract followed by 99.33% germination in seeds treated with Neem leaf extract (1:2W/V), 98.00% with nut sedge grass rhizome extract (1:2 W/V), 87.67% with Allamanda leaf extract (1:2W/V). Comparatively the lowest incidence of Bipolaris sorokiniana (14.00%) was observed in seeds treated with Neem leaf extracts (1:2W/V) followed by 14.50% in seeds treated with Nut sedge grass rhizome extracts (1:2W/V), Black cumin seed extracts (15.20%) and Allamanda leaf extract (24.00%).

To solve the multiple practical aspects raised by the achieving of cereals stocks protection (especially wheat and corn) against granary weevil Sitophilus granarius L., the research aimed a complex study on the sexual dimorphism at this species, aspect which help to prevent the weevils damages using unpollutant methods (with the aid of sexual pheromones, ovogenesis inhibitors, etc.). Due to the summarily data in the scientific literature of the world refering to the sexual dimorphism of the species, a detailed study was made within the Entomology Laboratory at the Faculty of Agriculture of USAMV Cluj-Napoca and at the Center of Electronical Microscopy of Babeş-Bolyai University in Cluj-Napoca (Romania), during 2005-2009
