Many entomologists work with plants nearly as much as they do with insects, since many insects are important pests of economically important plants. Insect respiration rates can be measured to assess insect health and growth. Insect herbivory can affect ecosystems by decreasing photosynthesis and net primary production. The herbivory can cause disruption of water and nutrient transport as well as directly affecting performance of photosynthetic enzymes within the tissue. Insect feeding may detrimentally affect plants' photosynthetic capabilities by interfering with light capture and energy transfer, regulation of H2O loss and CO2 uptake, and by disrupting the biochemical reactions that involve CO2 assimilation.
LI-COR Provides the Following Instruments for Entomological Research
The LI-6400XT is used in a number of different ecophysiological applications related to entomology.
- Insect Respiration
- Gas Exchange
- Leaf Chlorophyl Fluorescence
The LI-3100C can be used to measure leaf area in relation to entomology in a laboratory setting.
- Make rapid leaf area measurements related to insect defoliation with large numbers of harvested leaves.
The LI-3000C can be used to measure leaf area in relation to entomology using a non-
destructive method in the field.
- Study insect defoliation in the field
- The LI-3000C can also be used to study insect defoliation in the laboratory: it can measure harvested leaves when used with the LI-3050C Transparent Belt Conveyor Accessory.
The LAI-2200C makes plant canopy measurements related to entomology.
- Study insect defoliation by making leaf area index measurements in grasslands, forests, row crops, isolated trees, and hedges.
