This paper describes two new species of Eriophyoidea associated with trees belonging to the order Rosales in the south-western portion of East Azerbaijan province, Iran, collected during a survey in 2011: Aceria lobolinguae n. sp. on Elaeagnus angustifolia L. (Elaeagnaceae) and Rhinophytoptus nemalobos n. sp. on Prunus domestica L. (Rosaceae). Additionally, Phyllocoptes abaenus Keifer on Prunus...

This paper presents the results of analysis acetone, chloroform and diethyl ether extracts three types wormwood: Artemisia absinthium L., armeniaca Lam. latifolia Ledeb., performed by gas chromatography–mass spectroscopy. β-myrcene was found in A. from biologically active substances; latifolia, pinene; 3,6-difluoro-4-[1-hydroxy-2-(methiamino)ethyl]benzene-1,2-diol, ethyl palmitate, β-phellandre...

Pollen serves as an essential protein source for honey bee larvae. The nutrients in pollen greatly influence larval growth and development. Here, the survival, prepupal weight, developmental stage, digestibility midgut cells ( Apis mellifera L.) larvae were evaluated by performing vitro 5-ethynyl-2′-deoxyuridine (EdU) assays on reared three single pollens Brassica napus L., Armeniaca sibirica P...

Polyphenol oxidase from apricot (Prunus armeniaca) (PaPPO) was purified in its latent form (L-PaPPO), and the molecular weight was determined to be 63 kDa by SDS-PAGE. L-PaPPO was activated in the presence of substrate at low pH. The activity was enhanced by CuSO4 and low concentrations (≤ 2 mM) of SDS. PaPPO has its pH and temperature optimum at pH 4.5 and 45 °C for catechol as substrate. It s...

Allelopathic effect of apricot (Prunus armeniaca L.) root on some crops and weeds was investigated in two independent experiments.
