Isolation and identification of ecdysteroid phosphates and acetylecdysteroid phosphates from developing eggs of the locust, Schistocerca gregaria.
Maturing eggs of the desert locust, Schistocerca gregaria, contain a variety of ecdysteroid (insect moulting hormone) conjugates and metabolites, four of which have been previously isolated from polar extracts and identified as ecdysonoic acid, 20-hydroxyecdysonoic acid, 3-acetylecdysone 2-phosphate and ecdysone 2-phosphate. In the present study we have isolated eight additional ecdysteroids fr...
متن کاملOn the origin of the desert locust Schistocerca gregaria (Forskål) (Orthoptera: Acrididae: Cyrtacanthacridinae).
The locust genus Schistocerca (Stål) has a transatlantic disjunction, which has been controversial for more than a century. Among 50 species within the genus, only one species, the desert locust (S. gregaria Forskål), occurs in the Old World, and the rest occur in the New World. Earlier taxonomists suggested that the desert locust is a migrant from America, but this view was strongly challenged...
متن کاملPotential of the Desert Locust Schistocerca gregaria (Orthoptera: Acrididae) as an Unconventional Source of Dietary and Therapeutic Sterols
Insects are increasingly being recognized not only as a source of food to feed the ever growing world population but also as potential sources of new products and therapeutic agents, among which are sterols. In this study, we sought to profile sterols and their derivatives present in the desert locust, Schistocerca gregaria, focusing on those with potential importance as dietary and therapeutic...
متن کاملDNA damage in hemocytes of Schistocerca gregaria (Orthoptera: Acrididae) exposed to contaminated food with cadmium and lead
We measured in a comet assay the damage of DNA in the hemocytes of various stages of the grasshopper Schistocerca gregaria after exposing them to various doses of Cd and Pb in the food. The mechanisms of Cd and Pb toxicity for grasshopper are discussed. The accumulation of heavy metals and stage of the insect may play important roles in causing the DNA damage. S. gregaria may be considered a va...
متن کاملEcdysteroid titers in mated and unmated Drosophila melanogaster females.
Radioimmunoassay was used to determine ecdysteroid titers in mated or unmated Drosophila melanogaster females. Whole-body ecdysteroid titers increase after mating and this response is more pronounced after 12-24 hours than it is immediately after mating. In one experiment, females were mated to transgenic males deficient in accessory gland proteins to test whether these peptides mediate the obs...
