25 Φεβ 2024 · Chiggers are the larvae of the Trombiculidae mite species. Bites from these mite larvae can cause local pruritus and irritation called trombiculiasis or trombiculosis. The reaction is usually mild and self-limited, but the bites can transmit disease or result in bacterial superinfection.
When collecting the chiggers, the trap is turned over, and the chigger transferred by a wet brush onto a moistened filter paper in a collecting jar to extend the life of the chigger. This approach to keep the free living chiggers alive could also be used for the plate method of collecting (discussed earlier). 2.4. Chigger Lab Rearing
