Biogeostatistics and Sampling Technique about Spatial Pattern of Chinolyda flagellicornis Diapause Larva

The principle and method of biogeostatistics were used to study the spatial pattern of diapause larva of Chinolyda flagellicornis in Cupressus funebris stands with different damage degrees.The results show that the diapause larva appeared obvious spatial dependence in medium damaged Cupressus funebris stand,the range is 15.77 m,the half variance function is a exponential one,while the diapause larva of Chinolyda flagellicornis in heavy damaged Cupressus funebris stand appeared pure periodic change,the period was 6.806 2. The spatial sampling technique of diapause larva population of Chinolyda flagellicornis was also studied.
