American foulbrood (AFB) is the most serious brood disease of the honey bee. Traditional methods are reliable but rather slow simply because they are based on biochemical, morphological and physiological identification of cultivated isolates. The aim of this study is the detection of Paenibacillus larvae larvae spores in honey and diseased larvae samples by culture and PCR. Therefore 54 samp...

abstract the effect of different larval density of chilo suppressalis walker was evaluated through 2006-2008 on rice infestation in controlled condition of the cages. the results indicated that there were significant effects between dead hearts, white heads and crop yield. the highest dead hearts and white heads were related to the treatment of 32 larvae per m2 and the lowest ones were obtained...

American Foulbrood (AFB) is a major endemic disease affecting the bee brood and absence of chemical therapeutic treatments leads beekeepers to develop alternative management plans, based mainly on prevention accurate diagnosis symptoms. One main symptoms unpleasant odor caused by rot dead larvae. In present comparative study, we analyzed profile larvae presence characteristic volatile compounds...

An automated near–infrared (NIR) reflectance system was used over a two–month storage period to detect single wheat kernels that contained live or dead internal rice weevils at various stages of growth. Correct classification of sound kernels plus kernels containing live pupae, large larvae, medium–sized larvae, and small larvae averaged 94%, 93%, 84%, and 63%, respectively. Pupae + large larva...

During the summer of 1965, the fungus Spicaria rileyi was frequently associated with dead Pseudoplusia includens larvae on various crops in southeastern Alabama. Since this insect, sometimes referred to as the false looper, has become of increasing economic importance in Alabama (Canerday, J. Econ. Entomol., in press, 1966), the pathogenicity and potential control value of S. rileyi for P. k&de...

in the present study, the toxic effects on the embryos and larvae of the turbot were used as a model to investigate the diazinon, which contaminates aquatic ecosystems. the number of dead embryos significantly increased in response to diazinon concentrations 0.2, 0.4, 0.8, 1.6, 3.2, and 7.4 mg/l. the 48h lc50 value of diazinon for turbot embryos was estimated at 1.85 mg/l. dose–response decrea...
