Analysis of methidathion resistance mechanisms in Phytoseiulus persimilis A.H
Pesticide Biochemistry and Physiology, 1987Abstract A resistant strain of Phytoseiulus persimilis selected by methidathion pressure for several years metabolizes the [ 14 C]methidathion faster than does the corresponding susceptible strain. The metabolism is for the main part glutathione dependent and gives the methidathion conjugate on glutathione as a first metabolite: S [5-methoxy-2-oxo-

Species at the same trophic level may interact through competition for food, but can also interact through intraguild predation. Intraguild predation is widespread at the second and third trophic level and the effects may cascade down to the plant level.

Some common and different features in the intestinal enzymatic system functions were found in two species under study. Carbohydrases in both species have the same hydrogen-ion concentration optima that coincide with pH optima of similar enzymes of the prey and are close to the intestinal pH value.

Distribuzione meccanica di Phytoseiulus Persimilis in serra
2006Un prototipo per la distribuzione meccanica di Artropodi utili su colture protette è stato verificato con prove di laboratorio e di campo. In particolare, è stata valutata la distribuzione di Phytoseiulus persimilis Athias-Henriot. Nelle prove di laboratorio il prototipo ha dimostrato una capacità di esecuzione corretta del lancio di artropodi con ...

Rearing and mass production of the predatory mite Phytoseiulus persimilis
Entomologia Experimentalis et Applicata, 1985AbstractA method for mass rearing Phytoseiulus persimilis Athias‐Henriot is proposed. This predacious mite is maintained in rearing units composed of cylinders which contain leaves heavily infested with Tetranychus urticae Koch. The bottom of the cylinders is made of gauze. Fresh cylinders with prey are placed at regular intervals on tops of older ones

Morpho-functional changes in the alimentary canal epithelium and the process of food digestion are studied in mites. The changes in the epithelial cells of the midgut are shown to come very rapidly. Each 10-15 min. digestive cells degenerate. They are replaced by non-differentiated cells.

The structure of the digestive and- excretory systems in Phytoseiulus persimilis is described. It is established that the digestive system in Ph. persimilis is similar on the whole to the digestive system of other gamasid mites, though there are also some morphofunctional differences (no folding in the intestine and diverticula, etc.).

Distribution patterns of Phytoseiulus persimilis in response to climate change
Pest Management ScienceAbstractBackgroundThe biological control agent Phytoseiulus persimilis is a commercialized specialist predator of two agricultural pest mite species Tetranychus urticae and Tetranychus evansi. Biocontrol of these pest species by P. persimilis has achieved success in biological control in some areas.
