Wolbachia is a genus of intracellular bacteria typically found within the reproductive systems of insects that manipulates those systems of their hosts. While current estimates of Wolbachia incidence suggest that it infects approximately half of all arthropod species, these estimates are based almost entirely on terrestrial insects. No systematic survey of Wolbachia in aquatic insects has been ...
This investigation was aimed to evaluate water pollution with heavy metals using three biomarkers, as well as the study of the aquatic insects-seasons interaction. Three species of aquatic insects collected from El-Mansouriya stream (Dakahlia, Egypt), during the different seasons from spring 2014 to winter 2015. Water samples, sediments and whole body of the three aquatic insects were analyzed ...
Insects with over 30,000 aquatic species are known as very successful arthropods in freshwater habitats. Some of them are applied as biological indicators for water quality control, as well as the main food supply for fishes and amphibians. The faunistic studies are the basic step in entomological researches; the current study was carried out emphasizing on the fauna of aquatic insects in Karaj...
The true bugs (Insecta: Heteroptera) are one of the most important insects which included several pest and beneficial species (predators and parasitoids) and therefore have important role in agroecosystems. The fauna of aquatic and semi-aquatic Heteroptera was studied in paddy fields and around aquatic ecosystems in some regions of Iran through 2004-2009. Totally 58 species from 14 families inc...
In an investigation of the effects of the effluent of fish farms on the water quality of the Marbor River in Isfahan province based on biological indicators, some cases of infection of macrobenthos with horsehair worms (Nematomorpha: Gordiidae) were observed. About 76% of the observed worms were observed to leave their hosts. the horsehair worms were identified in only three families of aquatic...
Web-spinning spiders that inhabit stream channels are considered specialists of aquatic ecosystems and are major consumers of emerging aquatic insects, while other spider taxa are more commonly found in riparian forests and as a result may consume more terrestrial insects. To determine if there was a difference in spider taxa abundance between riverine web-spinning spider assemblages within the...
1. We used published data to investigate the combined influence of egg size and incubation temperature on embryonic development time for a broad assortment of aquatic insects at four different incubation temperatures (10, 15, 20 and 25 °C). 2. Embryonic development time (EDT) was positively correlated with egg size at each of the four temperatures, but with different relationships for univoltin...
