Lead, cadmium, mercury and arsenic are the most important heavy metals which may cause health risks following consumption of contaminated foods. Table salt is one the mostly used food additive with unique place in food consumption. Although purified table salt is expected to have lower level of contamination, some Iranians still prefer to use rock salt. Use of rock salt for food purposes has be...

The effect of low host plant nitrogen (N) content on herbivore performance has rarely been studied together with the herbivore’s feeding behaviour. We explored this relationship with juvenile Omocestus viridulus (Orthoptera: Acrididae) grasshoppers using fertilized and unfertilized host grasses. Due to lower growth rates, grasshoppers reared on N-poor grasses exhibited slightly prolonged develo...

Olive lace bugs (Hemiptera: Tingidae) are small sap-sucking insects that feed on wild and cultivated Olea europaea. The diversity of olive bug species in South Africa, the most important producer continent, has been incompletely surveyed. Adult specimens were collected Western Cape province for morphological DNA-based identification, sequencing complete mitogenomes. Cysteochila lineata, Pleroch...
