the purpose of this study was to investigate the status and epidemiology of intestinal parasites in iran. the information was driven from an extensive health survey which was done by the ministry of health and medical education, deputy of research affairs in 1990-92. sampling fraction was 1 per 1000 of individuals aged between 2 and 69, the sampling method was cluster sampling and each cluster ...

We characterized the dynamics of mortality factors affecting immature developmental stages of the fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae). Multiple decrement life tables for egg and early larval stages of S. frugiperda in maize (Zea mays L.) fields were developed with and without augmentative releases of Telenomus remus Nixon (Hymenoptera: Platygastridae) from...

because of endemic parasitological infectious diseases in iran and contaminated vegetables, as one of the most important ways of contamination, carried out a parasitical study on 263 vegetable samples from 44 farms in the suburbs of tehran city, and also 166 vegetables samples from 20 green grocery markets in the same city. from 263 samples of farms 147 cases (65%) of contamination were recorde...

Parasitoid wasps inject their eggs into host along with virulent factors to manipulate hosts physiology and immune system. Heat shock proteins (HSPs) are as molecular chaperones and stress proteins induced by heat, cold, anoxia and parasitism. There was no report about the roles of HSP in insect eggs against egg parasitoids. Here, we studied the expression profiles of several HSPs in silkworm e...
