Zooecdysteroids (arthropod steroid hormones) regulate the development of arthropods and probably many other invertebrates. Phytoecdysteroids are analogues occurring in a wide range of plant species, where they contribute to the deterrence of phytophagous invertebrates. The purpose of this short review is to summarise findings on the occurrence, metabolism and pharmacological effects of ecdyster...

Predominant phytophagous (plant-feeding) stink bugs in the southeast and much of the mid-South are similar and include the green stink bug, Acrosternum hilare (Say), the southern green stink-bug, Nezara viridula (L.), and the brown stink bug, Euschistus servus (Say). Several other species are part of the plantfeeding stink bug complex but are of less importance. Stink bugs will become more impo...

In the phytophagous corn earworm, Helicoverpa (Heliothis) zea, females delay their reproductive behaviors until they find a suitable host on which to deposit their eggs. Perception of volatile chemical signals from corn silk triggers the production of sex pheromone followed by its release, which leads to mating. Several natural corn silk volatiles, including the plant hormone ethylene, induced ...

We present proteome data from the microbiota (feces) after a diet shift from a natural diverse to a monocultural meadow with Dactylis glomerata. The abundant grasshopper species, Chorthippus dorsatus, was taken from the wild and kept in captivity and were fed with Dactylis glomerata for five days. For phytophagous insects, the efficiency of utilization of hemicellulose and cellulose depends on ...

Varga L. (2008): Hercinothrips femoralis (Reuter, 1891) – a new pest thrips (Thysanoptera: Panchaetothripinae) in Slovakia. Plant Protect Sci., 44: 114–118. Monitoring of pest species in plant production and extended trade on ornamental plant material, including precise identification, are the main goals of modern plant protection. As a result, a new species of phytophagous thrips – Hercinothri...

This paper defines the types of elm trees pests in Khorezm province Uzbekistan, carries out their systematic analysis, and also determines degree occurrence, as well natural enemies. The main phytophagous belong to 4 genera 14 species from 8 families. vast majority these pest have been identified Coleoptera pests. Pests were found be mainly that infect body part trees. In addition, 10 wild para...
