Food choice causes interrupted feeding in the generalist grasshopper Schistocerca americana: further evidence for inefficient decision-making.
Individual grasshoppers were observed foraging on either single food plant species or binary mixtures of them. Individuals ate slightly less on the mixtures, but grew faster on them. In the mixtures, individuals fed regularly from both plant species, typically eating both within a single meal. Feeding bouts were longer on the preferred plant species in the mixture. The pattern of foraging behav...
متن کاملArsenic hyperaccumulation in the Chinese brake fern (Pteris vittata) deters grasshopper (Schistocerca americana) herbivory.
Brake fern, Pteris vittata, not only tolerates arsenic but also hyperaccumulates it in the frond. The hypothesis that arsenic hyperaccumulation in this fern could function as a defense against insect herbivory was tested. Fronds from control and arsenic-treated ferns were presented to nymphs of the grasshopper Schistocerca americana. Feeding damage was recorded by visual observation and quantif...
متن کاملDisulfooxy fatty acids from the American bird grasshopper Schistocerca americana, elicitors of plant volatiles.
A previously unidentified class of compounds has been isolated from the regurgitant of the grasshopper species Schistocerca americana. These compounds (named here "caeliferins") are composed of saturated and monounsaturated sulfated alpha-hydroxy fatty acids in which the omega-carbon is functionalized with either a sulfated hydroxyl or a carboxyl conjugated to glycine via an amide bond. The reg...
متن کاملPresence of a single abundant storage hexamerin in both larvae and adults of the grasshopper, Schistocerca americana.
We identified a single hexameric storage protein in the grasshopper, Schistocerca americana, and monitored its abundance through the last larval instar and up until reproductive competence in adults of both sexes. This storage hexamerin, termed Schistocerca americana Persistent Storage Protein (saPSP) was the most abundant soluble protein in both larvae and adults. In both sexes, saPSP abundanc...
متن کاملQuantitative staging of embryonic development of the grasshopper , Schistocerca
During development of the grasshopper embryo, it is feasible to examine the structure, pharmacology, and physiology of uniquely identified cells. These experiments require a fast, accurate staging system suitable for live embryos. We present a system comprising (1) subdivision of embryogenesis into equal periods, (2) expression of stage in percent of complete embryogenesis time, (3) characteriz...
