The hygroreaction of the larvae of the Oriental rat flea Xenopsylla cheopis Rothsch. (Siphonaptera: Pulicidae)
Published online by Cambridge University Press: 06 April 2009
Extract
The humidity reaction of the larvae of Xenopsylla cheopis Rothsch. was studied in an air-chamber with a 0–100% relative humidity gradient.
Highly significant differences (P < 0·001) between the reactions in the various R.H. ranges was found. The most preferred relative humidity along this gradient was 100%. Relatively few larvae were collected at each R.H. in the range between 0 and 90% R.H.
The reaction of the larvae under the experimental conditions was seen to be of orthokinetic type.
