Itwas intended to in troduce the ug-to-now knowlege of protozoal viruses.

Investigation on arboviruses in Tianshui and Longnan regions of Gansu province;

Detection of three important arbovirus strains by reverse transcription polymerase chain reaction;

Biological characters of five Arboviruses;

Hemagglutination activity and cross hemagglutination inhibition test of five arboviruses;

13 species of arboviruses were selected in present study to establish DNA microarray for screening and identifying those viruses both in genus and species levels.

Arboviruses are a class of viruses that can spread diseases by blood-sucking arthropod bites vertebrates.

The threats caused by IM worms were analyzed,the solutions in existing applications and studies were analyzed and their strong points were made use of.

Based on the traditional theory of IDS,the system entropy is studied,which come from statistics model,combining the worm behaviors characteristic the exponent entropy conception is put forward,a new inhibiting method is proposed from the anomaly detection point of view.

This paper, based on analysis of distributed abnormal traffic sequence propagation, presents a new algorithm for detecting the Internet worm infection, and explores the forecast mechanism for worm traffic.

Research on worm virus flow in LAN

In light of the characteristics of the LAN in Laiwu Steel Group,based on a brief analysis of the characteristics of worm virus,its spreading approaches and outbreak features,this paper puts forward safeguarding measures against worm virus off enterprise LAN.

Meanwhile,it also analyzes the role of insect viruses insecticide in restoring and constructing the sta.

The development of insect virus study and its application in recent ten years in China are summarized.

It is an effective method of biological control to use insect virus to prevent pest.
