Laboratory experiments were carried out to investigate the efficacy of sugarcane bagasse-based lignin against four stored grain insect pests viz., Tribolium castaneum, Tribolium confusum, Sitophilus oryzae and Callosobruchus maculatus. Mortality was assessed after 24, 48 and 72 h of treatment and LD50 values were calculated at the respective time intervals. It was observed that T. castaneum is ...

In this study, contact and fumigant toxicities of methanol extracts and essential oils of Salvia tchihatcheffii and S. cryptantha plants against two main storage pests Sitophilus granarius L. and S. oryzae L.were tested. Evaluation of the results showed that the highest activity was obtained from S. tchihatcheffii plant. Stem extract of this plant had an insecticidal activity of 87% on S. grana...

Sitophilus oryzae (L.), S. granarius (L.), Tribolium castaneum (Hbst.), Oryzaephilus surinamensis (L.), Rhyzopertha dominica (F.), Tenebroides mauritanicus (L.), and Cryptolestes pusillus (Schon.) transmitted Salmonella montevideo from wheat contaminated with 10(6) organisms/g to clean wheat. The insects were fed on the contaminated grain for 21 days and were then transferred to clean grain and...

Rice product after wheat has special importance as the second agriculture strategic product. Rice weevil as one of the most important stored pest has the main role in losses of stored product. So in this research, the pest effects was studied on 4 common varieties of rice in Guilan province "Taroum, Hashemi, Ali kazemi and Dylamani" in two conditions of facultative and obligatory nutrition. Res...

Legal requirements and consumer demands for residue-free products pose a big challenge for pest control in grain stores. One possible alternative to chemical insecticides is biological pest control with the pteromalid wasp Lariophagus distinguendus against the weevils Sitophilus granarius, S. oryzae (Coleoptera: Dryophtoridae), and many other storage pest beetles. The use of this wasp as a bioc...
