Used in research to detect and quantify trypsin activity in insect samples, particularly in studies related to insect digestion, pest control, and host-pathogen interactions. Helps researchers evaluate trypsin-like protease expression in response to dietary changes, plant defense compounds, or genetically modified crops. Commonly applied in agricultural and entomological research to understand insect physiology and develop targeted biopesticides. Also useful in monitoring trypsin levels during laboratory rearing of insect species for consistent experimental conditions.
