To be or not to be a locust? A comparative analysis of behavioral phase change in nymphs of Schistocerca americana and S. gregaria.
Phenotypic plasticity in behavior induced by high rearing density is often part of a migratory syndrome in insects called phase polyphenism. Among locust species, swarming and the expression of phase polyphenism are highly correlated. The american grasshopper, Schistocerca americana, rarely swarms even though it is closely related to the swarming Old World desert locust, S. gregaria, as well as...
متن کاملEffects of different levels of locust meal (Schistocerca gregaria) replacement on growth function, survival, biochemical composition and intestinal digestive enzymes of rainbow trout fingerling (Oncorhynchus mykiss)
The present study was conducted to evaluate of different levels of locust meal (Schistocerca gregaria) on growth function, survival, biochemical composition and intestinal digestive enzymes in rainbow trout fingerling. Four experimental diets with different replacement levels of 0 (control treatment), 15 (SG15), 30 (SG30) and 60% (SG60) of fish meal with locust meal were formulated with equal p...
متن کاملIsolation and characterization of nine polymorphic microsatellite loci from the desert locust, Schistocerca gregaria
Because of the scarcity of polymorphic genetic markers, only a few genetic studies on the population structure of the desert locust, Schistocerca gregaria, have been carried out. We isolated and characterized nine polymorphic dinucleotide microsatellite loci. These markers were evaluated using individuals from Niger and Senegal. Seven of these microsatellite markers are also applicable to the n...
متن کاملOntogenetic effects on aerobic and anaerobic metabolism during jumping in the American locust, Schistocerca americana.
Developing vertebrates increase both their locomotory power output and endurance due to ontogenetic improvements in anaerobic and aerobic metabolic capacities. Do similar patterns hold for insect locomotion, or do longer tracheal lengths create problems for oxygen delivery in older animals? We forced developing American locust grasshoppers (Schistocerca americana) to jump repeatedly and examine...
متن کاملfMRI of emotional responses to odors: influence of hedonic valence and judgment, handedness, and gender.
Previous positron emission tomography studies of right-handed individuals show that the left orbitofrontal cortex is dominant during emotional processing of odors. We collected functional magnetic resonance imaging data from 28 subjects to study this network as a function of odor hedonic valence (pleasant vs. unpleasant), active hedonic judgments versus passive sensation of hedonically charged ...
