In this study, we reported the feasibility of using papaya skin extract (Carica papaya L.) as an alternative to enzyme pepsin in harvesting Gnathostoma spinigerum third-stage larvae. From experimental digestion, we found that the different numbers of recovered larvae between papaya skin extract and pepsin were not statistically significant (p >0.05). When the derived larvae from pepsin and papa...

The oviposition preference and larval performance of females of Ceratitis capitata (Wiedemann) were examined. Wild or laboratory-reared females were tested for oviposition preference in relation to papaya fruit in different stages of ripeness, as well as to two different fruits: papaya and apple. The results demonstrated that both laboratory-reared and wild females preferred ripe papaya fruit c...

The nomenclature of papaya viruses has been a source of confusion, primarily because symptomatology has been used extensively for describing papaya viruses. Although the literature is confusing and causal viruses for each of the diseases are not well identified, it appears that papaya viral diseases can generally be grouped as ring spot, mosaic and leaf curl, associated with poty, potex and gem...

The purpose of this experiment was to study the possible anthelmintic activity of papaya latex (Carica papaya) against Heligmosomoides polygyrus in experimentally infected mice. Five groups of BALB/C mice were infected with 100 Heligmosomoides polygyrus infective larvae/mouse. After patency (day 22) four groups of mice (groups B, C, D and E) were given papaya latex suspended in water at dose le...

Medicinal plants have played an essential role in the development of human culture. Carica papaya Linn.is a monoecious, dioecious or hermaphrodite tree; it belongs to the family Caricaceae. It is widely cultivated throughout world and is used as food and traditional medicine, particularly as an antiseptic and contraceptive. Papaya contains many biologically active compounds. Fruit, leaves, late...

Carica papaya Linn. is commonly called as paw-paw and it belongs to the family Caricaceae. Papaya possess excellent medicinal properties for treatment of different ailments. The different parts of the Carica papaya plant including leaves, seeds, latex and fruit exhibited to have medicinal value. The stem, leaf and fruit of papaya contain plenty of latex. The latex from unripe papaya fruit conta...

We report the case of a 76-year-old woman who experienced dizziness, vomiting, dyspnea, thoracic erythema, and vaginal itching within 5 minutes of eating cucumber. She had been diagnosed 3 months earlier with papaya urticaria and latex sensitization. The results of skin prick tests were positive for cucumber, watermelon, papaya, and latex and negative for melon and profilin extracts. ImmunoCAP ...

Papaya with resistance to papaya ringspot virus (PRSV) is the first genetically modified tree and fruit crop and also the first transgenic crop developed by a public institution that has been commercialized. This chapter reviews the different transformation systems used for papaya and recent advances in the use of transgenic technology to introduce important quality and horticultural traits in ...

Papaya meleira virus (PMeV) is the causal agent of papaya sticky disease, which is characterized by a spontaneous exudation of fluid and aqueous latex from the papaya fruit and leaves. The latex oxidizes after atmospheric exposure, resulting in a sticky feature on the fruit from which the name of the disease originates. PMeV is an isometric virus particle with a double-stranded RNA (dsRNA) geno...

Genetic relationships among Carica papaya cultivars, breeding lines, unimproved germplasm, and related species were established using amplified fragment length polymorphism (AFLP) markers. Seventy-one papaya accessions and related species were analyzed with nine EcoRI-MseI primer combinations. A total of 186 informative AFLP markers was generated and analyzed. Cluster analysis suggested limited...
