BACKGROUND Aquatic insects are very abundant and divers groups of insects that are associated with an aquatic or semiaquatic environment in one or more of their life stages. These insects have been, in some cases, well studied because they are vectors of several diseases. This is the first comprehensive faunistic study of aquatic insects from Babol County. The results may provide basic data for...

The mayfly species Paraleptophlebiawerneri has been rediscovered from Finland. The species was classified as RE (regionally extinct) in the most recent national red-list assessment. The new locality is close to the Russian border in NE Lapland, Savukoski. Adult males were collected with a sweep net around a pond. Paraleptophlebiastrandii is a rather poorly known but widespread Finnish species. ...

Are there many of them about? Just a few! Current estimates suggest there may be between one half and two million species; they are found in virtually every terrestrial habitat, and in a few freshwater ones. They include the smallest known insects — the tiny eggparasitising mymarids — as well as giant ichneumon-flies with egg-laying apparatuses (ovipositors) up to several inches long. Pass a sw...

An investigation was carried out over a year in the village of Chelow, Hormozgan Province, southern Iran, to study the efficacy of CDC light traps for sampling malaria vectors. The CDC light traps were useful in determining the seasonal and habitat distribution of Anopheles stephensi and An. fluviatilis, the primary and secondary vectors of malaria, in Chelow, as well as other mosquitoes in tha...

The common pistachio psylla Agonoscena pistaciae is a key pest of pistachio in Iran. A study was conducted to determine the spatial distribution of psylla nymphs and eggs in a 10 ha pistachio orchard in the Rafsanjan region, southeast of Iran. Three rows, each containing 33 trees (totally 99 trees), were randomly selected in the orchard based on a stratified sampling scheme. In each of the sele...
