The insecticidal activities of methanolic extracts two weedy plants leaves Bidens pilosa L. and Rumex dentatus at three different concentrations 3, 5 7% were tested against stored grain pests, Rice weevil Sitophilus oryzae Saw-toothed beetle Oryzaephilus surinamensis L., Bean Acanthoscelides obtectus Say, compared to Neem oil as a commercial product the same for exposure periods

For protection of stored agricultural products in ware house, grain store and food processing factory from insect damage, control measures should be taken. Stored pests are difficult to control. Though chemical insecticides effective controlling pests, other environment friendly methods have been advocated. Entomopathogenic nematodes potential bio agent for management pests. In this review rese...

bacillus thuringiensis strains were isolated from various soil samples collected from different regions of kahramanmaraş in turkey and were characterized by their colony morphology, pcr method with cryiab/ac, cryid, cry2 and cyt2 primers, and sds-page of crystal proteins with 130-140 and 60-70 kda molecular weights. plasmid profiles of selected isolates were also analyzed. among the cry genes s...

Five monoterpenes naturally occurring in essential oils were tested for their insecticidal and repellent activities against the bruchid beetle Callosobruchus maculatus and the maize weevil Sitophilus zeamais. The monoterpenes were highly efficient as inducers of mortality or repellency against both insect species. They were more efficient in their fumigant activity against C. maculatus than aga...

AIMS To develop a natural fungicide against aflatoxigenic fungi, to protect stored rice, using the essential oil of lemongrass. METHODS AND RESULTS Aspergillus flavus Link. was isolated from stored rice and identified as an aflatoxigenic strain. Lemongrass oil was tested against A. flavus and the test oil was fungistatic and fungicidal against the test pathogen at 0.6 and 1.0 mg ml(-1), respe...

Tribolium confusum and Sitophilus oryzae are stored product pests found worldwide. Environmental damages, human health issues the emergence of resistance driving scientists to seek alternatives synthetic insecticides for its control. Under this scenario, plant secondary metabolites being increasingly studied as bioinsecticides because they renewable, natural, biodegradable, non-persistent in en...

This paper presents a system for detection and recognition of pests in stored-grain based on video analysis. Unlike current systems which conduct analysis of static images, the proposed system uses video data captured by camera and performs video analysis to detect and recognize pests in grain. By using video data instead of static images, techniques such as motion estimation and multiple-frame...
