Abstract The results showed that foliar fertilization with potassium silicate had a clear effect on increasing the thickness of upper and lower epidermal cuticle layer increased leaf, as after first spray reached 22 microns 11 microns, leaf 194.8 microns. As for second spray, 198.66, 25.33, 16.66 third was characterized by an increase in compared to 206.66 epidermis 28.33 19 respectively. Compa...

The bacterial communities of aphids were investigated by terminal restriction fragment length polymorphism and denaturing gradient gel electrophoresis analysis of 16S rRNA gene fragments generated by PCR with general eubacterial primers. By both methods, the gamma-proteobacterium Buchnera was detected in laboratory cultures of six parthenogenetic lines of the pea aphid Acyrthosiphon pisum and o...

prey preference of natural enemies is among the phenomena that should be considered in determining the efficacy of natural enemies. when the predators are faced with a choice between two or more preys, they often show their preference to one from among them. temperature is one of the environmental factors that can affect insect foraging behavior. two aphid species namely aphis fabae and acyrtho...

animals that can estimate their desirable habitat quality are better able to accordingly adapt their life behaviors. the life cycles of parasitoids are so closely adapted as to match their hosts life behavior. among the various host-parasitoid interactions, a peculiarity is the seasonal synchrony between host and parasitoid activity. the foraging and oviposition behaviors of lysiphlebus fabarum...
