Changes in the hemolymph of female Haemaphysalis longicornis Neumann (Acari: Ixodidae) after infection by Heterorhabditis bacteriophora (Nematoda: Heterorhabditidae);

, Steinernema carpocapsae All, Steinernema carpocapsae A24, Steinernema feltiae SN, and Heterorhabditis bacteriophora H06, on the oriental fruit fly (OFF), Bactrocera (Bactrocera) dorsalis (Hendel) were investigated both in the laboratory and field.

Morphological measurement of infective juveniles and males showed that the population was most closely related to Heterorhabditis bacteriophora,while the results of ITS1-rDNA sequences alignment and phylogenetic analysis indicated that the population had the closest genetic relationship with H.

Phase variation of the symbiotic-pathogenic bacteria Xenorhabdus spp. and Photorhabdus spp.;

Isolation and structural identification of main component CB6-1 produced by Xenorhabdus nematophilus var.pekingensis;

The antifungal activity of secondary metabolic products from Xenorhabdus nematophilus YL001;

Antibiosis of Xenorhabdus nematophilus Metabolites Against Phytophthora infestans;

Influence of the haemocoel toxin (Tp40) from Xenorhabdus nematophila on enzyme activities and midgut tissues in Galleria mellonella (Lepidoptera:Pyralidae) larvae;

Evaluation of Toxicity and Safety of Xenorhabdus nematophila HB310 on the Silkworm,Bombyx mori;

Purification and characterization of the haemocoel insecticide Tp40 from Xenorhabdus nematophila;

A total of 66 populations were isolated from soil samples,among which 2 populations are Steinernema glaseri, 49 populations are Heterorhabditis bacteriophora.

Based on pathogenicity detection to the larvae of Galleria mellonella as host insect,the biological characteristics of three fine strains of insect pathogenic nematode in Gansu Province,including 0627M of Heterorhabditis megidis,0619HT of Steinernema feitiae and 0657L of S.
