dried fruit mite, carpoglyphus lactis l. not only to being one of the serious and economic pests of some stored products, but also to be used as an alternative prey for commercially mass rearing of predatory mites. in this study, life table parameters of dried fruit mite were examined on baker's yeast under laboratory conditions at three photoperiods including full darkness, full light and 16 :...
Scolothrips longicornis Priesner is one of the important predators of tetranychid mites with a wide distribution throughout Iran. Life table and population growth parameters of S. longicornis feeding on two-spotted spider mite, Tetranychus turkestani Ugarov & Nikolski were investigated under laboratory condition (26±1oC, 65±5% R.H. and 16L: 8D). To carry of these experiments, S. longicornis col...
the life table parameters of schizaphis graminum (rondani) (hemiptera: aphididae) on four commercial cultivars of wheat (kohdasht, pastor, tajan and zagros) were determined in laboratory conditions. fertility life table were constructed using age-specific survivorship (lx) and age-specific fecundity (mx) and subsequently analyzed using jackknife method and anova. there were significant differen...
