amitraz is one of the pesticides which is used in a vast area for controlling of the common pistachio psyllid, agonoscena pistaciae (hem.: aphalaridae). in this study the synergistic effect of piperonyl butoxide (pbo) on the toxicity of amitraz on adults of rafsanjan population of common pistachio psyllid was evaluated by residual contact vial (rcv) in laboratory conditions. the results showed ...

GASTRIC STABILITY STUDY OF SUPPLEMENTAL DIGESTIVE ENZYMES In order to meet the cellular demands of adequate nutrients, there must be a good selection of the foods containing the nutrients and also a good digestion/absorption within the gastrointestinal tract. This awareness to ensure good bioavailability of nutrients is gaining more interest. As a result, the administration of supplemental dige...

background: magnetite (fe3o4) nanoparticles are currently one of the important and acceptable magnetic nanoparticles for biomedical applications. to use magnetite nanoparticles for bacteria cell separation, the surface of nanoparticles would be modified for immobilizing of nanoparticles on the surface of bacteria. functionalization of magnetite nanoparticles is performed by different surfactant...

In the endosymbiotic unit of Paramecium bursaria (Ciliata) and Chlorella sp. (Chlorophyceae) algae are enclosed individually in perialgal vacuoles, which do not show acid phosphatase activity and thus differ from digestive vacuoles. Both types of vacuoles have been studied by freeze-fracture. Perialgal vacuoles are nearly spherical; their membrane always fits tightly to the algal surface. The v...

Purpose: To investigate the insecticidal activity of the essential oil of Cinnamomum cassis and its main constituent compound, trans-cinnamaldehyde, against the booklice, Liposcelis bostrychophila. Methods: Steam distillation of C. cassis twigs was carried out using a Clavenger apparatus in order to obtain the volatile oils. Gas chromatography/mass spectrometric (GC/MS) analyses (HP-5MS column)...

The inhibitory potential of purified α amylase inhibitors of sorghum on the digestive enzyme of Tribolium Castaneum, a devastating insect pest of economic importance have been studied. Qualitative and quantitative differences in α amylase of Tribolium Castaneum upon feeding on natural and artificial diets were evident. Natural diets were legumes like Black gram, Pigeon Pea, Red lentil, Cowpea a...

background: the german cockroach, blattella germanica l . , is a serious household and public health pest worldwide. con­trol of this species has been very difficult to achieve. toxicity of cypermethrin ec10%, deltamethrin ec5%, diazi­non ec0.5%, lambda-cyhalothrin ec5% and negon® (permethrin+propoxur oil liquid1%) commercial for­mula­tions were investigated against adult males of german cockro...

The essential oil of Clausena anisum-olens (Blanco) Merr. showed strong contact toxicity and repellency against Lasioderma serricorne and Liposcelis bostrychophila adults. The components of the essential oil obtained by hydrodistillation were determined by gas chromatography-mass spectrometry. It was found that the main components were myristicin (36.87%), terpinolene (13.26%), p-cymene-8-ol (1...
