Biology and predation of the Japanese strain of Neoseiulus californicus (McGregor) (Acari: Phytoseiidae)
TLDR
The life history characteristics and predation of the Japanese Neoseiulus californicus (McGregor) strain on the two-spotted spider mite, Tetranychus urticae Koch, were studied in the laboratory under 60–70% RH and 16L: 8D conditions to assess the effectiveness of theJapanese N. califORNicus strain as an important biological control agent against T. uricae.

Some factors affecting reproduction and sex ratios in two species of predacious mites, Phytoseiulus persimilis Athias-Henriot and Amblyseius andersoni (Chant) (Acarina : Phytoseiidae)
TLDR
Females of A. andersoni require multiple matings to maximize their reproductive potential but those of P. persimilis do not, and following certain food deprivation programmes, females increased egg production and produced proportionally more male progeny, compared with females under constant conditions of abundant prey. Expand
Effect of rainfall on a population of the diamondback moth, Plutella xylostella (Lepidoptera: Plutellidae)
TLDR
Under the same rain conditions as for the eggs, the falling rate of larvae decreased with advancing larval stadium except for the 1st larval stage, but when the density of droplet was increased or the period of rain was extended, there was an increase in the number of fallen larvae. Expand
Pathologic observations of pigs intranasally inoculated with serovar 1, 4 and 5 of Haemophilus parasuis using immunoperoxidase method.
TLDR
Nineteen, 7- to 13-week-old pigs were inoculated intranasally with different strains of Haemophilus parasuis, and the pathological lesions induced by each strain were compared, and H. Parasuis antigen was detected in lesions of infected pigs. Expand
Mating behaviour and reproductive mechanisms of two species of predacious mites, Phytoseiulus persimilis Athias-Henriot and Amblyseius andersoni (Chant) (Acarina: Phytoseiidae)
TLDR
In both phytoseiid predators, female fecundity increased with the duration of copulation, and the different mating patterns of the two species appeared to reflect their generic differences. Expand
Life history and reproduction of two species of predacious mites, Phytoseiulus persimilis Athias-Henriot and Amblyseius andersoni (Chant) (Acarina: Phytoseiidae)
TLDR
The basic biological characteristics of two species of predacious phytoseiid mites were studied in the laboratory and showed that P. persimilis had a higher reproductive rate during a shorter oviposition period and produced more progeny than A. andersoni. Expand
Effect of prey density on sex ratio of two predacious mites, Phytoseiulus persimilis and Amblyseius womersleyi (Acari: Phytoseiidae)
TLDR
It is concluded that the sex ratio of phytoseiid mites is not determined by the characteristics of the progeny, but by the nutritious condition of the females. Expand
Influence of temperature on the life history parameters of Tyrophagus similis Volgin (Acari: Acaridae)
TLDR
It is suggested that T. similis has the highest growth potential at 25°C, although lifetime fecundity was the lowest at this temperature. Expand
Effects of contact, oral and persistent toxicity of selected pesticides on Cotesia plutellae (Hym., Braconidae), a potential parasitoid of Plutella xylostella (Lep., Plutellidae)
TLDR
Effect of contact, oral and persistent toxicity of field doses of selected pesticides on immature and mature stages of this useful wasp were determined and beneficial performance of wasps seems to be adversely affected as host parasitism was recorded as being significantly different. Expand
