| coexistence of two effective parasitoids of the white peach scale pseudaulacaspis pentagona (hemiptera: diaspididae): the role of host stage and temperature. | encarsia berlesei: (howard) and pteroptrix orientalis (silvestri) are endoparasitoids of pseudaulacaspis pentagona (targioni tozzetti), that are sympatric in campania (italy). the influence of host stages on several components of e. berlesei fitness and the effect of mating status on the production of pteroptrix orientalis progeny were evaluated at 25 degrees c. parasitization of earlier host stages resulted in an increase in the development time and a decrease in progeny number of e. berlesei. ... | 2001 | 11228588 |
| survey of scale insects of ornamental plants in alexandria governorate, egypt. | this investigation covers a survey of the scale insects associating with some ornamental plants at three chosen public gardens as well as at the experimental farm of the agricultural research station in alexandria governorate, egypt. a total of nineteen scale insect species belonging to sixteen genera related to four families of the super-family coccoidea were found infesting eighteen ornamental plants during the period from april, 1998 up to march, 1999. these species are: family: asterolecanii ... | 2001 | 12425080 |
| irradiation as a phytosanitary treatment for white peach scale (homoptera: diaspididae). | irradiation was examined as a potential phytosanitary treatment to control white peach scale, pseudaulacaspis pentagona (targioni-tozzetti) (homoptera: diaspididae), a serious quarantine pest of papaya, carica papaya l., in hawaii. dose-response tests were conducted with second-stage nymphs, adult females without eggs, and adult females with eggs at a series of irradiation doses between 60 and 150 gy to determine the most tolerant stage. the adult female with eggs was the most tolerant stage. in ... | 2006 | 17195662 |

| developmental time and fecundity of white peach scale, pseudaulacaspis pentagona (targioni-tozzetti) (homoptera: diaspididae), on potato, kiwi and mulberry hosts in iran. | the white peach scale (wps), pseudaulacaspis pentagona (targioni-tozzetti) (homoptera: diaspididae), is a world wide polyphagous scale insect. it is widely distributed in north of iran, near the caspian sea areas, where it is the main pest of mulberry and kiwi trees. the development and fecundity of p. pentagona were examined at different temperatures and on different hosts in the laboratory. the longevity of wps decreased with a rise in temperature. at 25 degrees c the largest number of crawler ... | 2007 | 19090130 |
| molecular markers discriminate closely related species encarsia diaspidicola and encarsia berlesei (hymenoptera: aphelinidae): biocontrol candidate agents for white peach scale in hawaii. | we genetically characterized encarsia diapsidicola silvestri and encarsia berlesei howard (hymenoptera: aphelinidae) by two molecular methods: phylogenetic analysis of the cytochrome oxidase subunit i gene (coi) and intersimple sequence repeat-polymerase chain reaction (issr-pcr) dna fingerprinting. these two closely related endoparasitoids are candidate biological control agents for the white peach scale, pseudaulacaspis pentagona targioni-tozetti (hemiptera: diaspididae), in hawaii. we develop ... | 2010 | 20568638 |
| behavioral response of male white peach scale to the sex pheromone, (r,z)-3,9,-dimethyl-6-isopropenyl-3,9-decadien-1-ol propionate and corresponding alcohol. | males of the white peach scale,pseudaulacaspis pentagona (tar-gioni-tozzetti), in florida differ from this scale in france in their responses to putative pheromonal chemicals presented in a laboratory bioassay. males from florida were attracted to, and exhibited sexual (coputatory) behaviors at, the locus of evaporation of (r,z)-3,9-dimethyl-6-isopropenyl-3,9-deca-dien-1-ol propionate (p) (previously identified from effluvia of florida females). addition of the corresponding primary alcohol (a) ... | 1990 | 24263591 |
