MECHANICAL DISTRIBUTION OF PHYTOSEIULUS PERSIMILIS ON CHRYSANTHEMUM
Acta Horticulturae, 2012A prototype of a device for centrifugal distribution of arthropods was constructed in order to carry out the distribution of natural enemies both in open field and in greenhouses, installing three or more prototypes on a horizontal bar carried by a tractor or a wheel frame.Preliminary tests were conducted under laboratory conditions to evaluate the ...

This study focuses on the diagnostics of two natural enemy species, belonging to the genus Phytoseiulus in the family Phytoseiidae (sub-family Amblyseiinae): P. macropilis and P. persimilis. These two species are of primary importance in biological control all over the world.

Negative Evidence of Wolbachia in the Predaceous Mite Phytoseiulus persimilis
Experimental and Applied Acarology, 2005The cytoplasmically inherited bacterium Wolbachia is widespread in arthropod species and has been repeatedly detected in the predaceous mite Phytoseiulus persimilis. Our original goal was to assess the prevalence of Wolbachia infection in P. persimilis and the potential fitness consequences for this host. To accomplish that goal, seven P.

Vitellogenin (Vg) is an important factor that impacts oocyte maturation, egg formation and embryonic development in Arthropoda. Two orthologs of Vg gene were obtained from the genome of Phytoseiulus persimilis and termed as PpVg1 and PpVg2. Both orthologs belong to the large lipid transfer protein superfamily.

Spermatophore producing process and sperm transfer in Phytoseiulus persimilis
Experimental and Applied Acarology, 2018In phytoseiid mites, the spermatophore is an intermediate, isolated structure where sperms are stored during mating. In the present study, the producing process of Phytoseiulus persimilis spermatophore is described in details. Its shape, and the number and shape of sperms inside, are also analyzed, each as affected by coupling time.

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-

Expression and functional analysis of Niemann–Pick C2 gene in Phytoseiulus persimilis
Experimental and Applied Acarology, 2023As a new protein class of semiochemical binding and transporting, Niemann-Pick proteins type C2 (NPC2) in arthropods have received more attentions in recent decade. However, the gene function has not been studied in phytoseiid mites with biocontrol potential.

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 ...
