Anatomy of the Locust Tracheal System. The tracheal system of the American locust, Schistocerca americana, has a complex morphology, challenging our understanding of the paths and mechanisms of convective flows.Here we focus on the major structures ().There are 10 pairs of spiracles, 2 on the thorax, and 8 on abdominal segments I-VIII.The tracheae are supported by rings of thickened cuticle ...

How Locusts Breathe
How Locusts Breathe. Insect tracheal-respiratory systems achieve high fluxes and great dynamic range with low energy requirements and could be important models for bioengineers interested in developing microfluidic systems. Recent advances suggest that insect cardiorespiratory systems have functional valves that per-mit compartmentalization ...

Development of respiratory function in the American locust
However, our experiments did not distinguish between the effects of body size and development; to do so, the safety margin for oxygen delivery must be compared across individuals of different species at the same developmental stage. ...

Control of breathing rate
Investigate how carbon dioxide and oxygen in the air affect the breathing rate of a locust, and compare this with information collected from using a spirometer to investigate human breathing. Experiments. Investigating factors affecting the breathing rate of a locust
DOCX Title
Remove the piston and replace it with a loose plug of cotton wool. Exhale gently through the tube for 10 to 15 seconds (so that your exhaled air goes into the syringe barrel, but you inhale from your surroundings). Remove the cotton wool and replace the piston. Count the locust's breathing rate for three successive periods of 30 seconds.
A group of students examined the ventilation and gas exchange mechanisms of locusts.
Investigating respiration rate in living organisms
The experiment has a control with no insect in order to compare results. A wide variety of living organisms can be investigated including insects, woodlice, maggots or germinating peas. Figure ...
Practical: Investigating the Rate of Respiration
Method. Measure oxygen consumption: set up the respirometer and run the experiment with both tubes for a set amount of time (e.g. 30 minutes); As the seeds consume oxygen, the volume of air in the test tube will decrease (CO 2 produced during respiration is absorbed by soda lime or KOH) ; This reduces the pressure in the capillary tube and manometer fluid will move towards the test tube ...
Investigating the respiratory system of the locust.
Method: Firstly, I pinned the locust on its side to view the side of the thorax under a microscope. This meant I was able to look at the spiracles which were located periodically up and down the body. Once I had observes these, I pinned the locust to its back by placing a pin in each of its legs. In order to access the abdomen to look for the ...

Investigating Factors Affecting the Breathing Rate of a Locust
This Investigating Factors Affecting the Breathing Rate of a Locust Lesson Plan is suitable for 9th - 12th Grade. Do animals breathe faster when given more oxygen or more carbon dioxide? Young scientists observe the respiration rates of locusts under a variety of gas concentrations to answer that very question. They collect data, analyze the results, and discuss their conclusions.
Dissection of the ventilation system of a locust
Investigation: stage 2. g Fix a dead adult locust to the stage of a monocular microscope and examine the abdominal and thoracic spiracles more closely. You will need strong, oblique, top lighting and a very low magnification, but you should be able to distinguish between a true spiracle and a pit or depression.
Investigating the Breathing Rates of Locusts.
The reason that the locust's breathing rate increases, when there is an increase in the percent of Carbon dioxide in the locusts' environment, is that carbon dioxide directly affects the breathing rate. In locusts, the ventilation centre, in the metathracic ganglion, makes the control of the breathing rate. This is stimulated by nerve signals ...

We can investigate the production of carbon dioxide and heat from respiration through experiments using germinating seeds or other living organisms such as woodlice; Practical investigation: demonstrating the production of carbon dioxide.

An Experiment to Show the Rate of Respiration In a Locust
The aim of this experiment was to determine the rate of respiration of a locust using an instrument called a respirometer. Method The respirometer consisted of 2 equal chambers- an experimental one containing the respiring organism, and a control one, containing an equal volume of non-respiring material (in this case a marble).
Respiration Experiments
1) Mix yeast with glucose. Use the beaker to set up a water bath at 35°C. Label five test tubes 1 to 5. Shake the yeast and glucose mixture. Add 2 cm 3 of the yeast and glucose mixture to all five tubes. Place all five tubes in the water bath and leave them until the contents reach 35°C. Make sure the water bath stays at 35°C.
Ventilation systems
Ventilation systems. All multicellular organisms have mechanisms for drawing oxygen-rich air (or water) into their bodies and removing carbon dioxide-rich air (or water). A closer look at insect breathing systems makes it easier to appreciate the functions of the more familiar human ventilation system. A detailed study of human ventilation ...
Population Density-Dependent Developmental Regulation in Migratory Locust
Insect development is intricately governed by hormonal signaling pathways, yet the pivotal upstream regulator that potentiates hormone activation remains largely elusive. The migratory locust, Locusta migratoria, exhibits population density-dependent phenotypic plasticity, encompassing traits such as flight capability, body coloration, and behavior. In this study, we elucidated a negative ...
