in order to study, the effect of pre-cooling treatment, osmotic potential and water stress on some population of two species of satureja bachtiarica and satureja sahendica was studied by a factorial experiment based on completely randomized design with three replications in laboratory and greenhouse conditions during one year in the gene bank of institute of forests and range lands by the years...
Flight and emergence of the redbay ambrosia beetle, Xyleborus glabratus Eichhoff, were monitored from March 2011 through August 2012 using Lindgren funnel traps baited with manuka oil and emergence traps attached over individual beetle galleries on infested redbay (Persea borbonia (L.) Sprengel) trees.Of the 432 gallery entrances coveredwith emergence traps, 235 (54.4%) successfully produced at...
Emergence phenology and fitness attributes of several Colorado potato beetle, Leptinotarsa decemlineata (Say), populations were measured under field and greenhouse conditions. Anecdotal observations by producers and pest managers in many locations of the upper Midwest increasingly suggested that select populations of Colorado potato beetle were emerging over a longer period in the spring and we...
objective: to evaluate the mrna expression ratio of bcl-2/bax both in normal and tumoral bladder tissues of patients with transitional cell carcinoma (tcc) of bladder and investigate potential correlation between this expression ratio and clinical outcome. materials and methods: in this experimental study, we used real time-pcr to investigate the expression of bcl-2 and bax both in normal and t...
introduction: mass production of natural enemies has been considered a necessity for biological control programs. most beneficial insects have a relatively short shelf-life, so suppliers do not have a sufficient number of biocontrol agents. the development of storage techniques for biocontrol agents provides flexibility and efficiency in mass production. cold storage by prolonging insect develo...
In the current study, a field experiment was conducted to examine effects of litter on seedling emergence and early growth of four dominant weed species from the early successional stages of old field ecosystem and two perennial grassland species in late successional stages. Our results showed that increased litter cover decreased soil temperature and temperature variability over time and impro...
background: fasciolosis is an important health and veterinary problem in iran. the epidemiological pattern of disease has been changed markedly in recent years and there are regions that have potent capacity to be new focus of the disease. one of these areas is yasuj district in southwest of iran where animal fasciolosis has been quite common. the current study was conducted to determine the s...

Fecundity and sex ratio are the important factors in the quality control of parasitoid, Trichogramma. In this research, the effect of the host egg deprivation on these factors in Trichogramma brassicae Bezdenko was evaluated. The experiment was conducted with four treatments, each in five replications in a completely randomized design. Twenty mated females (24 h old) were transferred into the g...
