Melanoplus

We initiated this line of research by testing isolated compounds for their effects upon two Insects, the grasshopper (Melanoplus bivitattus or 11.. sanouinipes) and the tobacco hornworm, Manduca sexta. We could thereby test for activity against adult... 

Insect Control. Grasshoppers were chosen as an assay organism because they are a major crop pest in the grain producing plains and plateau states, they are readily available year round from the Agricultural Experiment Station at Montana State, and they are relatively easy to maintain in the laboratory. Two species, Melanoplus bivitattus and Melanoplus sanguinipes. have been used in these assays. 

Toluene did not induce sex-linked recessive lethal mutations or translocations, but did induce sex-chromosome loss and nondisjunction in male Drosophila melanogaster and induced mitotic arrest (C-mitosis) in embryos of the grasshopper, Melanoplus sanguinipes.

Terpenoids isolated in large quantities from resistant species were tested with several sunflower insect pests. Since sesquiterpene lactones were present in much higher concentrations than diterpenes in the most resistant species studied, our investigations emphasized sesquiter-pene lactones. Three species of insects were used in these studies Spodoptera eridania, Melanoplus sanquinipes and Homoeosoma electellum.

At present, there are few reports on the ecology of C. iria and associated insects and the information available is vague and contradictory. In the initial report on the isolation of JH III from C. iria, third stadium grasshopper nymphs, Melanoplus sanguinipes, were raised on either...
