1. Detection of the diapause adolescent of Paragonimus in boar's organs, such as liver, was doen by using normal saline-releasing technique.

2. The critical photoperiods for inducing ACB larval diapause were different in the geographic populations.

3. Photoperiod produces little influence on the diapause of housefly larvae.

4. Artemia cyst is the diapause egg of the artmeia hopper, dwelling in the salt-water reservoirs.

5. The results show that:(1)Morph-characteristics of diapause pupae during diapause period remain as in the early pupation stage.

6. One of the difficulties of the study in diapause is how to get enough butte flies.

7. The mycose concentration in diapause and non-diapause pupae were determined.

8. Unlike torpor(Sentencedict), diapause is a long - term state of suspension.

9. Under specific enviromental information, neuroendocrine cells produce and secrete diapause hormone ( DH ).

10. Objective To explore the effects of temperature and photoperiod on diapause of housefly larvae.
