The antifertility effects of Carica papaya were investigated by feeding adult cycling and pregnant rats with different components of its fruits. No attempt was made to force-feed the animals. The results indicate that unripe fruits of papaya interrupt estrous cycle and induce abortions. The abortifacient property seems to decrease as the fruit becomes stale or ripe. Exogenous progesterone count...

BACKGROUND Dengue is an infectious disease associated with high mortality and morbidity. Being a viral disease, there is no specific drug available for treatment. There are some reports that Carica papaya leaf extract may improve the clinical condition of dengue patients; however, to support this, at present, there is no systematically searched and synthesized evidence available. OBJECTIVES T...

Nowadays, there is an increased sustained interest in the production of plant-based-drugs for the treatment of many diseases. Moreover, people are welcoming traditional medicines to overcome mild/serious illness. Due to increase in the thrust for the production of plant-based antimicrobials, the present study was performed on Carica papaya leaves. The leaf extract was prepared by using acetone,...

Dressed in white, hooded ‘‘personal protection suits,’’ Greenpeace activists donned goggles, gloves, and respiratory masks—the kind of dress you expect to see in the clean zone of a nanotechnology laboratory, not in a field in bucolic northeast Thailand. Easily bridging a barbed wire fence with a stepladder, they began pulling transgenic papaya (Carica papaya) from the trees, throwing the fruit...

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 ...

In a pot experiment, BAU-Biofungicide (Trichoderma harzianum) neem oil and curaterr (carbofuran) 5G were tested against root-knot (Meloidogyne javanica) of two papaya varieties Kashempuri and Deshi papaya. Seedlings were inoculated with second stage larvae of M. javanica. Neem oil (5 ml/ 10g seeds) and BAU-Biofungicide (1:4) were used as seed treatant and curaterr as side dressing. Both the bio...

Dengue is an acute febrile viral infection affecting several tropical inhabitants. Carica papaya L. is a plant of choice for symptomatic treatment of dengue in several countries. In India, the plant, particularly the leaf extract is very popular in the management of Post Graduate dengue. Presently, several studies have been carried out on this plant to investigate its role in the management of ...

Papaya leaf distortion mosaic virus (PLDMV) is becoming a threat to papaya and transgenic papaya resistant to the related pathogen, papaya ringspot virus (PRSV). The generation of infectious viral clones is an essential step for reverse-genetics studies of viral gene function and cross-protection. In this study, a sequence- and ligation-independent cloning system, the In-Fusion(®) Cloning Kit (...

Cysteine proteinases from the fruit and latex of plants, including papaya, pineapple and fig, were previously shown to have a rapid detrimental effect, in vitro, against the rodent gastrointestinal nematodes, Heligmosomoides polygyrus (which is found in the anterior small intestine) and Trichuris muris (which resides in the caecum). Proteinases in the crude latex of papaya also showed anthelmin...

The efficacy of GF-120 NF Naturalyte Fruit Fly Bait in combination with field sanitation was assessed as a control for female oriental fruit fly, Bactrocera dorsalis (Hendel) (Diptera: Tephritidae), in papaya (Carica papaya L.) orchards in Hawaii. Three different bait spray regimes were evaluated: every row (high use of the bait), every fifth row (moderate use), and every 10th row (low use). Or...
