Individual size and abundance of the yeast-like endosymbiote in different geographic populations of brown planthopper, Nilaparvata lugens;

The yeast-like symbionts (YLS) were isolated and purified from the fat body of the brown planthopper, Nilaparvata lugens Stl (BPH) with different virulence reared on various rice resistant varieties.

The morphology and number of yeast-like symbionts(YLS) in three host-associated populations of Nilaparvata lugens(TN1 population,Mudgo population and ASD7 population) which had been reared on rice varieties TN1(susceptible),Mudgo(harboring resistance gene Bph1) and ASD7(harboring resistance gene bph2) for more than 117 generations,respectively were studied.

Effect of diets on abundance of yeast-like symbionts and development of the cigarette beetle,Lasioderma serricorne.;

Change in size and abundance of the yeast-like endosymbiote during the interaction between brown planthopper,Nilaparvata lugens(Stl),and resistant-variety rice;

The number of yeast-like endosymbiotes in the 3rd instar SBPH reduced by 23.

Relationship between yeast-like symbiotes and amino acid requirements in the rice brown planthopper, Nilaparvata lugens Stl (Homoptera: Delphacidae);

The relationships between yeast-like symbiotes and ovarian development and reproduction of the small brown planthopper,Laodelphax striatellus

Morphological characteristics of yeast-like endosymbiotes (YLES) in brown planthopper (BPH), Nilaparvata lugens Stl were studied by the cryostat microtome method in combination with the photomicrography.

The regularity of sterilization to staphylococcus aureus,escherichia coli 0157:H7,Listeria monocytogenes and saprophytic yeast on grape surface with chlorine dioxide gas were studied in this paper.

The regularity of sterilization to Staphylococcus Aureus, Escherichia Coli O157:H7, Listeria Monocytogenes and saprophytic yeast on apple surface with chlorine dioxide gas were studied.
